Chapter 374 Jeju Sewage Treatment Sail (Seeking the Moon)
"The old canal carries the memories of so many Jeju people. Nowadays, there are no more boats or fish and shrimps on the river. What's left is just black and smelly!
We, the descendants, and those in power, all have to feel guilty!
It is said that the three things a new official should do when taking office are for political performance and for people's livelihood!
Some people are keen to build squares, some are keen to build high-rise buildings, and some are keen to build development zones!
Then let me, Zhang Hua, start my three fires from the old canal!
According to myths and legends, Ksitigarbha Bodhisattva once made a great wish, vowing not to become a Buddha until hell is empty!
I have also made a great ambition today. If the old canal is unclear, I, Zhang Hua, will never leave!" Standing on the embankment of the old canal, Zhang Hua said loudly to the government officials accompanying him.
The accompanying reporters found various locations to take photos of Zhang Hua, recording Zhang Hua’s ambitions.
After Zhang Hua expressed his emotions and set his ambitions, he turned to Yu Qingyang and smiled: "Mr. Yu, the provincial party committee has approved Jeju City as a pilot city for market-oriented operation of sewage treatment!
I just said the big words!
Next, my political life will be handed over to your Huayu Investment Company!"
This is of course a joke, but it also represents Zhang Hua's trust in Yu Qingyang.
At the cost of his own political life, he invested for Hua Yu and stood up for Yu Qingyang.
We also told the sewage companies along the old canal through the media.
The management of the old canal is related to Zhang's political future.
If you dare not cooperate with the pollution control and affect my political future, then don't blame me for being ruthless.
Destroy people's futures without stopping!
This is Zhang Hua's ambition and Zhang Hua's declaration of war against coastal sewage companies.
"Mayor Zhang, on behalf of Huayu Water, I assure Mayor Zhang that we will make 200% effort to manage the old canal!
For this purpose we specifically contacted the German Carter Bass Company!
The world's most advanced water treatment technology was purchased from Carter Bass Water Treatment Company at a high price.
And we hired experts from Carter Bass Water Treatment Company to provide technical guidance to our company!
Tailor-made sewage treatment plant that is most suitable for Jeju City!" Yu Qingyang promised with a smile.
It is not difficult for Zhang Hua to add Jeju as a pilot city for market-oriented operation of sewage treatment.
There is no need to use political resources at home. The province needs more cities to serve as pilot cities.
Zhang Hua went to the provincial government to express his position and petition, and the province readily approved Jeju City's request.
As a pilot city for sewage treatment, Jeju City is also the first sewage treatment project since the establishment of Huayu Water.
Therefore, Yu Qingyang attached great importance to it and personally came to serve as the project manager of this project.
Sewage treatment is not a high-tech technology, and there are no embargoes or sales restrictions.
As long as there is money, all sewage treatment technologies in the world can be chosen by Huayu Investment Company!
Yu Qingyang contacted Carter Bass Water Treatment Company through the German Mo Amann Brothers Architectural Design Office.
We communicated several times on the phone, and the other party said that he would send someone to China to negotiate in the near future.
What Yu Qingyang bought was not sewage treatment equipment or drawings of a sewage treatment plant, but a set of technologies and a set of sewage treatment processes.
China's sewage treatment really started in the 1990s, and it did not begin to develop rapidly until the 21st century.
At present, China is the world's largest consumer of sewage treatment and the largest importer of sewage treatment.
According to Yu Qingyang’s understanding, there are currently many sewage treatment technologies in China.
And it's still relatively advanced, but it's still not up to the world's leading level.
The technology Yu Qingyang plans to introduce is naturally the most advanced sewage treatment technology in the world.
Through three-level treatment, it can reach the standard of gray water.
The first-level treatment is called physical treatment, also called mechanical treatment.
The mechanical treatment section includes structures such as grilles, grit tanks, and primary sedimentation tanks for the purpose of removing coarse particles and suspended solids.
The principle of treatment is to achieve solid-liquid separation through physical methods to separate pollutants from sewage. This is a commonly used sewage treatment method.
Mechanical treatment is an essential project for all sewage treatment processes. The typical removal rates of BOD5 and SS in the primary treatment of urban sewage are 25% and 50% respectively.
Secondary treatment is biochemical treatment, with the main purpose of removing unsettled suspended solids and dissolved biodegradable organic matter.
Its process composition is diverse and can be divided into activated sludge method, AB method, A/O method, A2/O method, SBR method, oxidation ditch method, stabilization pond method, CASS method, land treatment method and other treatment methods.
Currently, most sewage treatment plants use the activated sludge process.
The principle of biological treatment is to complete the decomposition of organic matter and the synthesis of organisms through biological action, especially the action of microorganisms, and convert organic pollutants into harmless gas products (CO2), liquid products (water) and organic matter-rich products.
solid product.
The excess biological sludge is separated from solid and liquid in the sedimentation tank and removed from the purified sewage.
Tertiary treatment is an in-depth treatment of water. It is the wastewater treatment process after secondary treatment and is the highest treatment measure for sewage.
At present, not many sewage treatment plants in our country have been put into practical use.
This is also the reason why Yu Qingyang specially imported a complete set of sewage treatment technology from Germany at a high price.
It denitrifies and dephosphorizes the secondary-treated water, removes remaining pollutants in the water using activated carbon adsorption or reverse osmosis, disinfects with ozone or chlorine to kill bacteria and viruses, and then sends the treated water into the central
Water pipes are used as water sources for flushing toilets, spraying streets, watering green belts, industrial water, fire prevention, etc.
After the entire treatment process, although the standard of drinking water Yu Qingyang wanted was not obtained, the gray water obtained was already more advanced than 99% of domestic sewage treatment plants.
At present, many sewage treatments in China only meet the primary treatment standards and barely meet the discharge standards. Better ones can meet the secondary treatment standards.
The rest needs to rely on nature’s purification function to digest the sewage.
The reason for this is still related to the issue of cost.
The cost of third-level in-depth processing is too high, and ordinary enterprises cannot afford it, or are unwilling to afford it.
Building a sewage treatment plant to centrally treat sewage is also mandatory sewage treatment.
"Okay! I leave my political future and the fate of the old canal in your hands, Huayu Investment!
What we do next is up to you, and our city government will fully cooperate!" Zhang Hua waved his arms and said loudly.
"Mayor Zhang, our company will organize German experts to come to Jeju as soon as possible to conduct on-site inspections and design a sewage treatment plant suitable for Jeju City."
Yu Qingyang repeatedly emphasized German experts and German technology in order to increase confidence in the Jeju City Government.
Although they don’t want to admit it, Chinese people still worship foreign things.
Some are overly superstitious about foreign technology.
