Chapter 108 Water Quality Inspection Report Results
Xu Li asked Zhang Chong to use a small basin to collect the sewage from the ditch.
Although Zhang Chong felt sick, he still did as he was told.
Xu Li gently opened the petri dish, and then put part of the phagocytic bacteria into the sewage basin.
After waiting for almost five minutes, the sewage in the basin showed obvious changes.
I saw that the sewage in the basin became clear at a speed visible to the naked eye. The original turbidity and filth disappeared, replaced by "little silk sprouts" like dodder seeds, but these "little silk sprouts" soon disappeared.
Missing.
"Here's the principal..."
Zhang Chong on the side looked shocked.
If Xu Li hadn't introduced the unknown phagocytic bacteria just now, he would have thought the principal was doing magic!
The clearness of the sewage must be related to the phagocytic bacteria in Xu Li's hands.
Is it possible...
Zhang Chong seemed to have thought of something.
"Okay, let's get a few more pots and take a look."
Xu Li was not surprised by this single effect. He needed to conduct multiple experiments so that he could be guaranteed.
So, the two began to get busy.
But this time I used some cups, ten of them.
After introducing the phagocytic bacteria, the results were the same as the first time.
"Okay, Teacher Zhang, please send these ten samples to the Inspection and Quarantine Center in Fengcheng for inspection to see if they meet the standards. The specific inspection fees will be reimbursed by the school."
Xu Li turned to Zhang Chong and ordered.
Currently, there is only one CMA-qualified third-party testing agency in Fengcheng, and it is public, so it is still reliable in terms of credit.
"No problem, principal."
Zhang Chong knew what this meant, so he packed up his things, took a taxi and took the samples to the hospital.
"Principal, what experiment were you doing just now?"
"Why did I see that the sewage became clear just now?"
"Did you get some magical potion in your hand just now?"
After Zhang Chong left, curious students gathered around and asked.
Because the scene just now also surprised them.
"I will announce this when the time comes. You all should disperse now!"
Xu Li doesn't plan to make the Phagocytosis public yet, and will wait until the inspection report comes out.
Seeing Xu Lidu say this, everyone had no choice but to disperse.
However, one or two students among them recorded the scene just now with their mobile phones and posted it online. No one knows what kind of Internet waves it will cause.
The other side
Twenty minutes after taking a taxi, Zhang Chong arrived at the Inspection and Quarantine Center in Fengcheng and began to line up according to the procedures to prepare for the water body inspection.
"One water inspection costs 1,200."
The girl at the window quoted the price. Zhang Chong handed the sample test tube to the girl, and then took the school's reimbursement voucher for reimbursement.
I have to say, this inspection costs 1,200 per time, which is really expensive!
If Zhang Chong was asked to pay for it himself, he might feel a little uncomfortable, but fortunately the school would be responsible for the reimbursement.
Then Zhang Chong sat in the waiting room and waited, because it would take at least an hour before the test results came out.
He just has to wait here.
He took out his mobile phone and browsed short videos, otherwise it would be quite boring to wait.
"Have you heard? Several factories in the industrial zone were found to have sewage discharge problems. After testing, many harmful substances exceeded the standard!"
"I've also heard about this. It seems to be close to Linjia Village, right? I heard that many villagers went to the factory with carrying poles to argue."
"Sigh~ What's the use of this? If we don't file a lawsuit and close the factory completely, it will only treat the symptoms but not the root cause."
At this time, Zhang Chong heard several middle-aged men discussing around him.
Factory wastewater?
Zhang Chong was slightly startled.
In fact, news about this kind of news is common in China.
Nowadays, various regions are too pursuing economic benefits and forgetting about the environment and ecology. Many third- and fourth-tier cities with relatively backward development will introduce some industrial or electronic manufacturing companies in order to promote the economy of the region.
But such economic benefits are only temporary.
Nowadays, many factories have many pollution discharge problems. Although the country has promulgated relevant policies in recent years, all polluting enterprises must meet the pollution discharge standards before they can discharge.
But this kind of "pollution discharge standard" is not something every company can meet, because it requires purchasing a set of advanced pollutant treatment equipment, which costs millions and tens of millions.
Therefore, many bosses secretly discharge sewage in order to save money, which will also affect nearby residents over time.
Just when Zhang Chong was stunned, the sound of the radio sounded.
"Please ask Mr. Zhang Chong on the 12th to collect the inspection report and inspection samples...!"
Hearing that it was his turn, Zhang Chong quickly went to the collection window to receive the inspection report and sample test tubes.
Zhang Chong opened the report and his eyes shrank slightly.
【Microbial indicators】
Total coliforms: 0
Escherichia coli:0
Thermotolerant coliform:0
【Toxicological Indicators】
Arsenic, selenium, carbon tetrachloride, cadmium, cyanide, bromate, chromium, fluoride, formaldehyde, lead, nitrate, chlorite, mercury, chloroform, and chlorate all display zero p>
【Drinking Water Disinfectant Index】
Chlorine and free chlorine preparations, ozone, monochloramine, chlorine dioxide: 0
Finally, the sensory properties and general chemical indicators, such as iron, total dissolved solids and aqueous solution pH, have almost reached the minimum value within the qualified range.
If this has been sterilized or treated with high temperature, wouldn’t it be possible to drink it directly?
Zhang Chong couldn't help but think boldly.
"No, hurry back and show it to the principal!"
So Zhang Chong hurried back to school happily.
After Xu Li received the report, his face was calm and calm, obviously expecting such a result.
"Teacher Zhang, please don't announce this matter for now. I will compile a paper."
"Okay."
Zhang Chong nodded. After all, this thing was created by the principal himself, and he had no say.
The reason why Xu Li let Zhang Chong know about this was to prepare for the next thing.
However, he did not tell him the cultivation methods and core secrets. After all, no one else knows the core secrets in the laboratory except Xu Li himself. Even Li Mo cannot tell him the core technology without reservation.
Him.
It is better for him to be cautious now. When the time comes, he will create a core technical team...
After all, people are the biggest variable.
"By the way, principal, I have built something in the laboratory these days, so I would like to hear your opinion."
Zhang Chong suddenly thought of something and said hesitantly.
"Oh? What did you make?"
Xu Li was a little curious. He had previously asked Zhang Chong to guard the phagocytosis bacteria and allowed him to conduct his research experiments under the rules.
I didn’t expect this guy to actually do it.
"This...I can't explain clearly, please follow me to the laboratory to have a look!"
Zhang Chong quickly replied, he knew that since Xu Li had created such an awesome phagocytic bacterium, he must have achieved something in biology.
