The rise of nanometers

The Golden Week in early October has not passed long.

At Shanmei Vocational and Technical College in Shanmei City, Cai Haiyizheng accompanied city leaders to inspect the college.

Cheng Gaoyu, who visited the college once last year, was not surprised when he saw the tin houses and small shops at the college gate after getting off the bus.

There is a cement bridge at the gate of the college, and underneath is the Xinlou River, which is four to five meters wide. Suddenly he took a look at the river water and found that the river water was very clear.

I stopped and stood next to the railing of the bridge for a while, looking along the river. The water was crystal clear, the mountains of garbage on both sides were gone, and I didn't smell the stench.

Cheng Gaoyu turned his head: "Hai Yi, you have done a good job in the governance of the city."

"I'm ashamed to say that this Xinlou River is managed by Suiren Company." Cai Haiyi replied with a smile.

Cheng Gaoyu was stunned and asked: "Oh? Is it the Suiren Company that has become famous recently?"

"Yes, this is the company."

"Tell me about it. It seems that the city has changed a lot."

Cai Haiyi said that in the past six months, there have been some changes in the city, and the public health situation in the streets and alleys has undergone a huge change. Basically, there is no accumulation of garbage.

The most important thing is that the rivers flowing through the city and the water quality of Pinqing Lake have undergone a transformation.

Since the sewage discharge from the upstream farms is blocked, sewage pipes and sewage rivers within the city are also continuously sucking away sludge.

In addition, the sewage discharge of two electronics factories and a paper mill were also contracted by Suiren Company.

The pollution situation in the entire city has entered a virtuous cycle, and a large number of pollution phenomena have been reversed bit by bit.

The people who feel it the most are actually not Cai Haiyi or Cheng Gaoyu, but the residents living on the banks of rivers and lakes.

After inspecting the college, Cheng Gaoyu did not go back immediately. Instead, on a whim, he asked Cai Haiyi to lead the way upstream along the Xinlou River.

The previous garbage mountain has disappeared without a trace, and some newly grown weeds on the ground are erasing the traces of the past.

When we visited the six or seven pig farms owned by local villagers, although there was some smell, it was not that serious. Cai Haiyi explained that it was because the farms were equipped with sewage storage tanks and did not discharge directly to the open air, so there was not much odor.

"This model is good. It seems that other counties will also promote it."

Cai Haiyi, who smiled bitterly after hearing this, hurriedly explained the reason: "Judging from the current situation, unless they are all contracted to Suiren Company, other companies may not be able to do it."

"Is it a technical problem?" Cheng Gaoyu thought thoughtfully.

Cai Haiyi nodded: "It's just a technical problem. Without this technology, it would be difficult for enterprises to make profits in contracting sanitation, unless there are large financial subsidies."

"I've heard a little bit about this."

"Speaking of which, the urban area is still benefiting from the Suiren Company. Their projects in Tuocheng and Rongcheng charge very high prices, and they also include the management rights of the water company."

Cheng Gaoyu returned along the road, asked his assistant to change the itinerary, and then asked Cai Haiyi to take him to inspect several urban-rural fringe areas, Kuishan Lake, Pinqing Lake, and several farmers' markets.

The minibus parked next to a river bank of Pinqing Lake. Next to it was a river that merged into Pinqing Lake. He had just inspected this place once when he was transferred from Pengcheng a year ago.

At that time, he stood here, watching the dark river water pouring into Pinqing Lake. The middle reaches of the river was the Xinli Electronics Factory, and the upper reaches were a large number of small breeding farms.

Now that he has returned to his hometown, he found that the pollution situation in the river has greatly improved. He can even see small fish in twos and threes, looking for food and playing in the river.

Maybe in a year or two, this will become a good place for fishing.

The minibus started again, but instead of returning, it headed towards Pubian Town. On the way, Cheng Gaoyu, Cai Haiyi and others inspected Lingfeng Paper and Dechang Electronics Factory and found that the sewage problems here had also been reversed.

Then I passed through Guizhuling Industrial Park and entered the recycling factory in person, watching the trucks of garbage being transported into the processing workshop.

Liquefied gas manufacturing workshop.

Cheng Gaoyu, wearing protective clothing and a safety helmet, asked the new factory director Li Shuzheng: "Director Li, how much liquefied gas can your factory produce in a day?"

Li Shuzheng, a gentle man, replied: "The production is about 120 to 140 tons a day, depending on the amount of garbage collected."

Cheng Gaoyu asked curiously: "Is so much liquefied gas produced from garbage?"

"They are all garbage or waste, including domestic garbage, sewer waste, farm waste, public toilet waste, factory waste, etc."

Suddenly Cheng Gaoyu asked a question: "I heard that your company has developed water purification technology and harmless recycling technology. Is this technology applicable to all industrial wastewater?"

Li Shuzheng gave some general information: "Judging from the current testing situation, it is very good for the recycling of solid waste and sewage. However, it still needs to be verified for waste gas pollution and nuclear pollution."

Hearing this situation, Cheng Gaoyu made a mental note.

Finally, we visited the deep recycling workshop of the recycling factory, where a large number of harmful substances are decomposed or extracted separately from wastewater and waste.

In the heavy metal recycling workshop, there are nameplates on the collection boxes, which are gold element collection boxes, silver element collection boxes, cadmium element collection boxes, copper element recycling boxes, etc.

Across the glass window, Cheng Gaoyu asked with interest: "Can elements really be extracted from wastewater and waste?"

"This is natural. The heavy metal recycling workshop gives priority to electronic wastewater and electronic waste. Our company contracts the wastewater waste from Truly Electronics Factory and Dechang Electronics Factory, which contains a large amount of heavy metals."

Cheng Gaoyu tentatively asked: "I heard that Tuocheng Guiyu Town is the world's capital of e-waste. Your company's technology should also be applied here, right?"

"It is indeed possible, but the situation there is complicated. Local snakes are doing this business, and our company is powerless." Li Shuzheng expressed helplessness.

Regarding this issue, Cheng Gaoyu has been working in Shanmei for more than a year and feels very troubled. After all, the Chaoshan area has extremely serious clan influence and side fishing, and many companies are actually aborted.

Many of the people who deal with electronic waste in Tuocheng have a gray background. To do this business, you need to have connections at home and abroad, otherwise it will be difficult to make money.

And he is not in charge of Tuocheng, so he has no control over matters on that side.

After leaving Guizhuling Industrial Park, the minibus continued towards Haifeng County. Cheng Gaoyu, Cai Haiyi and others inspected Meilong Town and Ketang Town.

The backward production capacity transferred from the Pearl River Delta region has indeed brought local employment and promoted economic prosperity.

But Cheng Gaoyu also saw the other side. Electroplating factories, hardware factories, jewelry factories, and jewelry factories have brought serious pollution.

Especially in Meilong Town, he saw many residents on both sides of the river who did not even dare to drink tap water and had to go to the mountains to fetch spring water.

On the minibus back, Cheng Gaoyu summarized what he saw and heard. If Suiren Company had not appeared, Shanmei would have no choice but to rely on undertaking backward production capacity in developed areas and sacrifice the environment to develop the economy.

But in Guizhuling Industrial Park, he saw another path, and it was a feasible path.

If it can succeed, it will not only be a good thing for the local residents, but also a good thing for our own future.
