"Ladies and gentlemen, I have a different opinion here on the location of the sewage treatment plant!" Yu Qingyang had to contradict again.

At the scheduling meeting, Mayor Zhang Hua, Standing Committee Deputy Mayor Yang Yabin and other leaders spoke about mobilization, and then began some specific matters of the old canal governance.

The first is the location of the wastewater treatment plant.

"It's true that we are treating the old canal this time, but in terms of the location of the sewage treatment plant, should we broaden our horizons?

When considering a location, don't just stare at the old canal!

Jeju City has three rivers running through the municipal district, the Old Canal, the Grand Canal, and the Bulpu River!

Among them, the old canal and the Zhufu River are all black and smelly water bodies!

Each black and smelly river has a different pollutant discharger.

If our sewage treatment plant is only targeted at the sewage enterprises in the old canal, will it cause a boycott from the sewage enterprises?

There is an old saying in China that if you don't suffer from poverty, you will suffer from inequality!

If we can't treat pollution equally, then such a problem will inevitably arise.

Everyone is a sewage company, why can he discharge sewage directly into the river, but I have to pay for it?"

As in the previous generation, the leaders of the Jeju Old Canal Management Working Group placed the address of the sewage treatment plant on the edge of the old canal, next to an abandoned wharf.

There is no problem with the sewage treatment plant being placed on the river's edge.

The problem is that it is not appropriate to put the sewage treatment plant on the West Bank.

This directly limits the number of polluting enterprises.

If companies on the east coast want to connect sewage pipes to sewage treatment plants, the pipes have to cross the river, which invisibly increases the cost of laying pipelines.

In addition, the old canal is east of the Zhufu River, and the high-tech development zone of Jeju City is on the east side of the Zhufu River.

This is equivalent to the enterprises in the high-tech development zone and the sewage treatment plant separated by two rivers.

How can this work?

This is increasing the construction cost of Huayu's investment.

There are two ways to concentrate sewage in the sewage treatment plant, one is to lay pipelines to direct the sewage from the enterprise to the sewage treatment plant.

The second is to use a sewage collection truck, similar to a tanker truck, to transport it to the sewage treatment plant.

Separated by two rivers, the cost of collecting sewage either way would be significant.

Therefore, Yu Qingyang resolutely put forward different opinions.

We must resist this kind of thinking of spending other people's money without feeling distressed.

"Mr. Yu, we have not ignored the sewage discharge enterprises on the east bank of the Zhufu River!

The problem is that the polluting companies on the east bank of the river are too far away!

Even if we put the sewage treatment plant on the east bank of the old canal, it is still not close!

Is it economically reasonable to continue to use pipes for sewage collection?

So the last time we had a discussion, we were thinking about whether we could use tankers to collect sewage!" Yang explained.

In addition, the old canal runs north-south through the center of Jeju and turns west to join the Grand Canal.

That is, there are a large number of residents on the east and west banks of the old canal, and whether the sewage treatment plant is placed on the east or west bank, there are some municipal pipelines that need to cross the river. Liu Qiyao, director of the Environmental Sanitation Bureau, also stood up and explained.

"Another consideration for choosing the West Bank is that there are more residents on the east bank and fewer residents on the west bank, so the difficulty of demolition is much smaller!" Zhao Ming, director of the Planning Bureau, also came forward to explain.

"Hehe! Leaders!" Yu Qingyang took a sip of tea unhurriedly, "Just like what Director Zhao said just now, there are more residents on the east coast, and the discharge of domestic sewage is naturally much larger! The number of enterprises and urban residents on the east bank is more than double that of the west coast.

Moreover, I would like to ask you another question, leaders, you can be said to be the decision-makers of Jeju City! So in what direction will Jeju City develop in the future?

As for the difficulty of demolition and relocation mentioned by Director Zhao just now, as far as I know, the opposite bank of the sewage treatment plant selected in our city is also a piece of farmland like the west bank!

A little further east of the farmland are the old fertilizer factory and the carbon factory! At present, the old fertilizer factory has ceased production, and it seems to have been purchased by Linghua MSG! I don't know how Director Zhao's so-called statement that the demolition and relocation on the west bank is smaller than that on the east bank came about!

Yu Qingyang's words were not polite at all, and they pierced Zhao Ming's heart.

None of the Jeju city leaders attending the meeting expected that Yu Qingyang would be so familiar with Jeju.

"In addition, there is no problem in considering the use of tankers to transport industrial wastewater! However, have you ever thought about how much is the price of sewage treatment? How much does it cost to transport a ton of industrial wastewater by tankers?

Will the transportation costs be paid by the polluting company, or by the sewage treatment plant?"

"Naturally, the sewage treatment plant will transport it by itself!" blurted out Liu Qiyao, director of the Environmental Sanitation Bureau.

"Hehe! From the high-tech zone to the sewage treatment plant designated by our city leaders, the transportation distance is about 20 kilometers! Here we do not consider the sewage of Sun Paper, but only the sewage discharge enterprises in the high-tech zone.

How much does it cost to transport 20 kilometers? A 20-ton tanker truck costs about 100 yuan for a round-trip freight! That is, a ton of freight costs 5 yuan!

Director Shen, the price I quoted, even if it is applied to the transportation of muck, should not be expensive?"

"It's not expensive! Twenty kilometers of muck transportation costs more than 20 yuan per cubic meter!" Shen Qixin, director of the construction committee, said in a sullen voice.

"Leaders, how much do you plan to charge for pollution control per ton of sewage?" Yu Qingyang asked another pointed question.

This is not a later generation, the state promulgated the "Regulations on Urban Drainage and Sewage Treatment" specifically on the discharge of urban residents' sewage and industrial wastewater, and the price of industrial wastewater has reached the point of hundreds or even more than 2,000 yuan per ton.

If Yu Qingyang dares to charge a pollution control fee of 100 yuan per ton from a polluting company, people can spray him to death.

The market-oriented operation of the sewage treatment plant is still in the trial stage, and even if it matures in the future, it is a semi-public welfare enterprise.

It is impossible to price too high.

The general pricing method is that the construction cost is amortized equally to each year according to the depreciation rate, and the depreciation cost is calculated, plus the annual maintenance cost, plus the operating expenses of the sewage treatment plant, plus a certain profit, and finally divided by the estimated amount of sewage to be treated, to obtain the pollution control fee standard.

Under normal circumstances, one ton is generally about ten yuan.

"Our city area is 50 square kilometers, and the permanent population is about 500,000, and a sewage treatment plant with a daily sewage treatment capacity of 200,000 tons can meet the needs of the entire city!

Of course, taking into account the expansion of the area of the town and the growth of the resident population, I propose to consider the design of the daily processing capacity according to the daily processing capacity of 500,000 tons!

The completion of the first phase will reach a daily processing capacity of 200,000 tons, and the investment will be about 500 million!

Coupled with the transformation of municipal pipelines, the cost of laying sewage pipelines of sewage enterprises is about 200 million!

The construction cost of the first phase is about 700 million!

Based on the payback period of 20 years, the average annual cost is about 35 million!

The daily processing capacity is 200,000 tons, and after deducting the shutdown maintenance, the sewage treatment plant can run for 350 days a year, and the annual sewage treatment capacity is 70 million tons.

35 million plus the cost of maintenance and repair, plus the operating expenses, according to 60 million!

In this way, the cost of treating one ton of sewage is about eight cents and six cents. Plus the profit, a dollar?

Even if the high-tech zone is a little farther away, and the cost of laying sewage pipelines is high, let's add 100 million yuan to the construction cost, okay?

In total, the cost of sewage treatment is just over a dollar. ”

Yu Qingyang suddenly calculated the account, at first everyone didn't understand, what he was doing with this account, and finally when he reported the cost of sewage treatment, everyone understood what Yu Qingyang meant.

This is to tell them that the normal cost of sewage treatment is just over a dollar, and if you consider using a tanker truck with a freight of five yuan a ton to transport sewage, you are almost scolding them for being a loser.

Of course, this cost refers to ordinary industrial wastewater, excluding toxic and polluted industrial wastewater.

Toxic pollutants industrial wastewater refers to substances that contain toxicity and are not easily biodegradable, including heavy metals, toxic compounds and organic compounds that are not easily biodegradable.
