"The old canal carries the memories of many Jeju people, and now there are no boats on the river, no more fish and shrimp, some are just black and smelly!

We, the descendants, those of us in power, must feel guilty!

It is said that the new official takes office with three fires, whether it is for political performance or people's livelihood!

Some people are keen to build squares, some people are keen to build high-rise buildings, and some people are keen to engage in development zones!

Then my Zhang Hua's three fires will be burned from the old canal!

In myths and legends, King Jizo Bodhisattva once made a great wish, hell is not empty, vow not to become a Buddha!

I also made a grand wish today, the old canal is not clear, and I, Zhang Hua, will never leave!" Standing on the embankment of the old canal, Zhang Hua said loudly to the government cadres accompanying him.

The accompanying reporters found various positions to take pictures of Zhang Hua and record Zhang Hua's ambitions.

After Zhang Hua expressed his emotion and made a grand wish, he turned his head and smiled at Yu Qingyang: "Mr. Yu, the provincial party committee has approved Jeju City as a pilot city for the market-oriented operation of sewage treatment!"

I just said the big thing!

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 in Huayu and stood up for Yu Qingyang.

It was also through the media that the pollutant discharge companies along the old canal were told.

The management of the old canal is related to the political future of our people.

If you dare not cooperate with the anti-pollution campaign and affect my political future, then don't blame me for being ruthless.

Ruin people's future, never die!

This is Zhang Hua's ambition, and it is also Zhang Hua's declaration of war against coastal sewage enterprises.

"Mayor Zhang, on behalf of Huayu Water, I would like to assure Mayor Zhang that we will work hard to make 200% efforts to manage the old canal well!

For this purpose, we contacted Carter Bess in Germany!

Purchased the world's most advanced water treatment technology from Carter Bess Water Treatment Company at a high price.

And hire the experts of Carter Bess Water Treatment Company to provide technical guidance for our company!

Tailor-made for the most suitable sewage treatment plant in Jeju City!" Yu Qingyang assured with a smile.

Increasing Jeju as a pilot city for the market-oriented operation of sewage treatment is not a difficult task for Zhang Hua at all.

There is no need to even use the political resources of the family, and the province needs more cities to be pilot cities.

Zhang Hua went to the provincial government to express his stance and petition, and the province happily approved Jeju City's request.

Jeju City, as a pilot city for sewage treatment, is also the first sewage treatment project since the establishment of Huayu Water.

Therefore, Yu Qingyang attached great importance to it and personally came over to serve as the project manager of this project.

Sewage treatment is not a high-tech technology, and there is no embargo or ban on sale.

As long as there is money, all the sewage treatment technologies in the world can be selected by Huayu Investment Company!

Yu Qingyang contacted Carter Bess Water Treatment Company through the German architects of Mo Aman Brothers.

After communicating several times on the phone, the other party said that he would send someone to China to negotiate in the near future.

What Yu Qingyang bought was not the drawings of sewage treatment equipment and sewage treatment plants, but a complete set of technologies and a complete set of sewage treatment processes.

China's sewage treatment really started in the 90s of the last century, and it was not until the 21st century that it began to develop rapidly.

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 many sewage treatment technologies in China.

And it is relatively advanced, but it has not yet reached the world's leading level.

The set of technologies that Yu Qingyang is preparing to introduce is naturally the world's most advanced sewage treatment technology.

Through tertiary treatment, the standard of reclaimed water can be achieved.

Primary treatment, called physical treatment, is also called mechanical treatment.

The mechanical treatment section includes structures such as grids, grit removers, and primary sedimentation tanks for the purpose of removing coarse particles and suspended solids.

The principle of treatment lies in the separation of solid-liquid through physical methods to separate pollutants from sewage, which is a commonly used sewage treatment method.

Mechanical treatment is an essential project for all sewage treatment processes, and the typical removal rates of BOD5 and SS in the primary treatment of municipal wastewater are 25% and 50%, respectively.

Secondary treatment is a biochemical treatment with the primary purpose of removing non-sinkable solids and dissolved biodegradable organic matter.

The process composition is diverse, which 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.

At present, most sewage treatment plants use the activated sludge method.

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 transform organic pollutants into harmless gas products (CO2), liquid products (water) and solid products rich in organic matter.

The excess biological sludge is separated from the purified sewage by the solid-liquid separation in the sedimentation tank and removed from the purified wastewater.

The tertiary treatment is the advanced treatment of water, which is the wastewater treatment process after the secondary treatment, and is the highest sewage treatment measure.

At present, there are not many sewage treatment plants in China that have been put into practical application.

This is also the reason why Yu Qingyang specially introduced a complete set of sewage treatment technology from Germany at a high price.

It will carry out denitrification and dephosphorization treatment of the secondary treated water, remove the remaining pollutants in the water with activated carbon adsorption method or reverse osmosis method, and disinfect bacteria and viruses with ozone or chlorine, and then send the treated water into the reclaimed water pipeline as a water source for flushing toilets, spraying streets, watering green belts, industrial water, fire prevention and other water sources.

After the whole treatment process, although Yu Qingyang did not get the standard of drinking water he wanted, the reclaimed water obtained was more advanced than 99% of the sewage treatment plants in China.

At present, many domestic sewage treatment only meets the primary treatment standard, barely reaching the discharge standard, and the better one can meet the secondary treatment standard.

The rest needs to be digested by nature's purification system.

The reason for this is that there is still a question of cost.

The cost of tertiary deep processing is too high for ordinary enterprises to afford, or are unwilling to bear.

The construction of sewage treatment plants to carry out centralized treatment of sewage is also mandatory sewage treatment.

"Okay! I put my political future and the fate of the old canal in the hands of your Huayu investment!

Next, it's up to you to do what you do, and our municipal 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 has repeatedly emphasized that German experts and German technology are to increase confidence in the Jeju municipal government.

Although I don't want to admit it, the Chinese people are still a little flattering to foreigners.

Some are overly superstitious about foreign technology.
