When he was thinking about what else to write, there was a noise outside. It turned out that Wu Nanhai from the agricultural team and He Ping, who was sent by Shi Niaoren to disinfect the toilets, had a quarrel and came all the way here to explain. Although He Ping traveled through time
He used to be an employee of a large state-owned pharmaceutical factory. He was actually doing maintenance work on equipment and instruments. He didn't know anything about drugs and pharmacology. The health team wanted him here because his wife, Zhao Yanmei, worked in the pharmaceutical factory's mold seed laboratory.
Shi Niaoren, a technician at the company, was preparing to work on a pharmaceutical factory project in the future. Zhao Yanmei had to keep Zhao Yanmei first. To keep a wife, of course, she had to keep her husband.
He Ping, who has a rectangular face, glasses, and a scholarly look, simply became a clerk in the health department, doing odd jobs and running errands. How come he got into a quarrel with someone for no reason?
When I went out, I saw the fat man Wu Nanhai grabbing He Ping with an angry look on his face, while He Ping looked aggrieved and was holding a nylon bag containing lime in his hand.
"Did you ask him to spread lime?" Wu Nanhai saw the leader coming out and focused his firepower on Shi Niaoren.
"What? Is there a problem? Our health team is disinfecting the toilets."
"Do you understand chemistry?" Wu Nanhai pointed to lime, "Farm manure such as manure is a nitrogenous fertilizer and cannot be mixed with alkaline fertilizers such as plant ash and lime. The result of mixing will be neutralization failure. You are so powerful
What's the use of the excrement in the toilet if you sprinkle it with lime?!"
Shi Niaoren's face was very ugly. After all, he was also a doctor studying in the United States. Medicine was called a beast. He had performed surgery in the United States and had been prevented from epidemics in the imperial capital. Wouldn't it be a huge loss of face to question an undergraduate from the No. 1 Agricultural University if he knew chemistry?
. But then I thought about it, Wu Nanhai is the person in charge of agriculture and one of the executive committee members. Agriculture is an industry that the executive committee is planning to develop quickly. In the future, many logistical support matters may have to rely on the agricultural department - he
He was the person in charge of the sanitary den. After the two persons in charge had a fight in front of each other, they couldn't even move around in circles. He calmed down a little and suppressed his anger. He really never thought about the issue of fertilizer efficiency, so he used lime to
Toilet disinfection is the simplest and most common disinfection method. When disposing of the excrement of infectious patients, disinfection with lime is almost a necessary procedure.
"This is our negligence." Shi Niaoren hurriedly greeted Wu Nanhai and coaxed Wu Nanhai away with kind words. Xiao He looked unhappy - he was being criticized for not performing the leadership task.
"Isn't it just big shit? Just give him a few more dips!"
"We are also learning through practice." Doctor Shi reassured his soldiers, "Wu Nanhai needs fertilizers for agriculture - crops and flowers." He glanced at the lime bag and saw that not much was used. Lime is still lime.
He got it from the construction engineering department - he couldn't bear to part with the bleaching powder - and planned to use it to treat drinking water.
Lime cannot be used, and bleaching powder is reluctant to part with it, so the harmless treatment of feces has to be thought of separately. Shi Niaoren's main field is infectious diseases, and he is no stranger to epidemic prevention. He knows that there are many kinds of harmless treatment of general excrement.
Lime, bleaching powder, etc. work quickly. If not, the easiest way is to store it in a sealed place, but it requires a third-level septic tank - at worst, a septic tank... How about some natural plants? He remembered that he had seen it
His book said that some natural wild plants can also be used as substitutes. The problem is that he can't remember which plants they are, and he has never studied Chinese medicine, so even if he knows the names, he may not be able to recognize them.
Just as he was thinking about whether he should make a report and ask where there are talents in traditional Chinese medicine, Tian Jiujiu came in again and asked the health team what kind of water treatment method they planned to use so that they could come up with a water supply plan for construction as soon as possible.
"This is really one out and one in." Shi Niaoren murmured to himself.
"What?" Tian Jiujiu was confused.
"Nothing, I'll come to the construction site right away."
The water supply system is under the direct control of the health team. The shallow groundwater near Bopu has high salt content and is not suitable for drinking water. They have no conditions to exploit the deep water. The only feasible option is to pump water from the Wenlan River.
.
As a water supply, the most ideal is spring water or deep groundwater. Rivers like the Wenlan River have large flows and good self-purification capabilities, and they are also usable water sources. However, this is a river delta area, and the water quality is generally poor.
If there is greater pollution, water treatment will be more complicated.
Shi Niaoren tested the water depth and flow rate, and extracted 250ml of water samples from 50 centimeters below the water surface. He did not have any testing equipment, so he had to use the simplest method of visual inspection and nose smelling.
After seeing the results, he shook his head repeatedly. He originally thought that the river water should be very clean based on the pollution level in the 17th century. The fact is that although there is little sediment in the water, there is a lot of algae. This shows that the content of organic matter in the water is too rich. This
Of course, there is nothing strange in modern time and space - it is all caused by chemical fertilizers, but there were no chemical fertilizers in the Ming Dynasty. Such high organic matter content only shows that the middle and upper reaches of the river are developed agricultural areas or residential areas.
Of course, it is not impossible to use this water. According to Ji Niao Ren's observation, this water is still Category 3 water according to modern standards - the water intakes of some modern city water plants cannot meet this standard.
If such water quality is to be used as drinking water, a rather complicated set of sedimentation, filtration, and disinfection processes must be used. No matter which water supply mode is adopted, sedimentation tanks, filter wells, disinfection tanks, water channels... are required for building materials that are in short supply.
Isn’t this a fantasy for the engineering team?
Taking into account the bad infectious disease situation in ancient times, there was a high possibility that the water contained cholera and typhoid bacteria. Shi Niaoren thought twice and thought that it would be better not to use river water until there was no condition to establish water treatment facilities.
"It's better to send fresh water from the boat to the shore." He sighed and went directly to Ma Qianxu to report.
Ma Qianzhu didn't know much about how to solve the fresh water problem on the ship, so he called Mond and asked him.
"There is water on the ship, but it can't hold it for long." Mond explained: The general hull design has at least two fresh water tanks. One stores drinking water, which is the fresh water connected to the shore after entering the port;
Daily water is distilled water condensed from the cooling water of the main unit. This kind of soft water obtained by desalination of sea water is usually used for sanitary washing and is generally not drunk. Sometimes the drinking water is not enough, you can also drink it.
Because Fengcheng was designed as an ocean liner, it has four fresh water tanks and a considerable water storage capacity. However, the original design was to supply forty or fifty crew members, and now there are nearly 600 people, which is a bit difficult. Supplementary
The amount of newly generated distilled water when the machine is running is limited, and it cannot be supplied on a large scale for a long time.
"Use auxiliary engines to provide fresh water!" Ma Qianzhu frowned after listening to his report, "This is exchanging diesel for water!" He felt a little regretful, "There is no diesel flowing in the river."
Shi Niaoren knew that he was worried about the oil on the ship, but he knew that in Lingao, intestinal infectious diseases such as cholera, typhoid fever, and paratyphoid fever were very widespread in history. Until the 1970s and 1980s, cholera and typhoid fever were still rare.
A large-scale outbreak. Although the people across the country are now vaccinated thanks to modern medicine, there is no guarantee that they will be fine - even if they don't get infectious diseases, an acute enteritis outbreak will be enough for them.
After expounding the pros and cons, Ma Qianzhu had no choice but to accept this suggestion. In order to save water as much as possible, the command headquarters decided after discussion: to set up a centralized water supply station on the shore, lay water hoses with floating barrel lines, and lead fresh water from the ship to
There is a 2-ton capacity stainless steel water tower in the living area - for drinking and washing only.
"As for taking a bath, let's get over it for now." Ma Qianzhu knew that this policy of limited fresh water supply would definitely attract countless curses to him, but he had no choice but to do this. He sat down and drafted a document, which was sent by oa.
"Building materials" he wrote on his notepad. Many things today are restricted by this building material. He must try to solve them during the meeting in the evening.
The dusk was getting thicker, and the day of D-Day was about to pass. As the order to "end work" came from the walkie-talkie, the travelers who had been working at the outer construction site for a day gathered in twos and threes towards the camp.
The people in the logging team were returning from the mangroves while talking. They were carrying tools on their shoulders. Although they were physically tired, everyone had warm emotions in their hearts, and their feelings for each other seemed to have improved a lot.
The tide is receding, and the sea water is washing away the large and small rocks in the bay. Looking from a distance, the western skyline shows the outline of Lingaojiao. The blood-red sunset slowly sinks among the scattered clouds and haze. The view of Bobu Bay
The sky, light, and sea colors blended into each other and shone brightly. The sea water, as if it had been burned by fire, turned golden and red.
The fleet of traversers was anchored in the bay one after another, and the dark shadows of the ships were inlaid with a radiant golden edge by the sunset. These ordinary cargo ships and fishing boats, to them at this moment, were like the ones in Pascual Bay.
The Imperial fleet is generally magnificent.
This magnificent scenery made them mesmerized, and the inexplicable excitement made them silent. Not only them, but also those who came back from other peripheral construction sites also slowed down and looked at this gorgeous and magnificent scene.
"Everyone, let's go quickly, it's getting dark." The military team member at the back greeted them and checked to see if there were any stragglers. According to the plan, they had to go last to ensure that no one was still there after dark.
Outside the camp.
"Guntower!" someone shouted, and everyone looked in the direction of the camp. An earthen fence had been built around the standing beacon tower, and a barbed wire fence had been erected on it. At first glance, it looked like a Japanese guntower in an old movie.
After a day of construction, the entire camp began to take shape. With the beacon tower and the inspection department's house as the core, the entire camp was in the shape of an irregular pentagon. A trench 5 meters wide and 2 meters deep was dug on the periphery, which attracted Wen Lan.
When the river is filled, the inside of the trench should be built 1 meter higher than the outside, and a barbed wire fence should be laid on top. The barbed wire is 2 meters high, cross-fixed with wooden stakes, and buried very firmly. The lower part of the barbed wire is also laid with bellows-type barbed wire. After the barbed wire, there is another
The dug soil was piled and rammed into a long fort, with trenches dug on top. In addition, six 8-meter-high wooden sentry towers were built on the long fort.
At this time, torches were lit along the long ramparts, illuminating the trenches. The gate of the camp was open. On the gatehouse, two sentries were holding rifles, standing next to a searchlight. Two carbide lamps were hung below the gatehouse, and the light was
The light is blinding. Travelers pass through the gate, scan the dog tag at the manpower registration desk at the door, and then return tools and excess materials at the planning committee's storage point.
"Liu Zheng, right?" The female clerk in the human resources team looked at the personal information and photos displayed on the computer screen, and then compared them with his face, "Your barracks number is No. 14, Building B."
