The rise of nanometers

Shanmei City is very close to Pengcheng. If you drive through the Shenhai Expressway, you can get from Pengcheng to Shanmei City in more than two hours.

A bus came down from the Pubian Expressway intersection, then went straight to Shanmei Avenue in the city, and found an ordinary business hotel.

There were 23 people in total, led by a scholar-type middle-aged man wearing an ordinary white shirt. He was Li Jiye, deputy district chief of Pengcheng.

Among the traveling companions were people from Pengcheng’s sanitation, environmental protection, and business sectors, as well as experts in five related fields.

After putting their luggage away, the group left the hotel and started hiking in Shanmei City. They did not walk all the way on the main roads, but even inspected some small alleys, urban villages, and urban-rural fringes.

Contrary to the expected mess, despite the overall backwardness of the city's infrastructure, the garbage is cleaned up in a very timely manner.

From time to time, you can see automatic sweepers and automatic sprinklers running back and forth on the road.

The areas that sanitation workers are responsible for are corners and small alleys that are difficult to clean mechanically.

There were also a lot of trash cans, but there were no classified trash cans. However, Li Jiye was impressed by the anti-tipping design of the trash cans.

What surprised the group even more was the fast suction trucks. During the two days of inspection, they encountered no less than twenty suction trucks.

As a professional, Xiao Dongming developed the molecular permeable membrane at this time. During the operation of these fast fecal suction trucks, there is indeed a fast management system that can filter sewage.

Li Jiye asked curiously: "Professor Xiao, can this kind of treated water really reach drinking water level?"

"I don't know yet. The water is quite clear by visual inspection, but the specific situation requires sampling and testing." Xiao Dongming did not dare to make a conclusion.

When they tried to approach the septic suction truck, they were stopped by the operator, who refused to allow Li Jiye and others to approach on the grounds that it involved company secrets.

When we came to the Xinlou River, which had been treated before, all the garbage and debris on the river had been cleaned up, and the sewage on the dirt road where sewage had previously flowed across the river had also disappeared.

The sludge in the river was also dug up by Blue Age Company.

Walking upstream along the Xinlou River, they discovered many breeding farms. Although the smell was quite unpleasant, the phenomenon of random discharge of sewage and feces everywhere did not occur.

Several farmers also felt very strange when they saw a group of strangers who were still neatly dressed.

Li Jiye quickly asked with a smile: "Fellow, you are raising pigs well."

A middle-aged man who was lighting the fire replied casually while adding more firewood: "It's just so so. There are no leftovers to collect recently. I can only eat feed, vegetable leaves and sweet potatoes."

"Why don't you see pig manure in your farm?" Li Jiye said insinuatingly. He had worked in rural areas, but he knew that small farms like this had no concept of pollution control at all.

"In the pots in the back, people come to collect them every once in a while. They come."

Talk about Cao Cao, Cao Cao arrives.

A fast fecal suction truck drove down the dirt road from the entrance of Shantou Vocational College and came to the breeding farm here. The name and trademark of "Blue Era" were printed on the truck.

Li Jiye was not surprised by this familiar name.

As a group of people watched, an operator opened the lid of a plastic tank buried underground. The lid was similar to a sewer manhole cover and added a lock.

Insert the sewage suction pipe into the tank and quickly draw out the sewage and pig manure inside. A large amount of filtered pure water flows out from the drain outlet on the other side.

The water level in the small ponds dug by the farmers quickly rose. Although they did not consume the recycled water, it was very convenient for watering vegetables and flushing pig houses.

The middle-aged farmer handed a card similar to a bank card to the driver: "Old Wei, see how many points I have?"

The driver inserted the card into the on-board computer and refreshed the data: "There are 1,437 points, which can be redeemed for organic fertilizer. If you want to redeem liquefied gas, there is still a lot left."

"Thanks."

"You're welcome."

The compressed dry matter in the sewage tank can be exchanged for one point per kilogram of dry matter. These points can be exchanged for sea and land gas and sea and land organic fertilizers.

This also promotes the enthusiasm of farmers, allowing them to take the initiative to discharge sewage and pig manure into sewage storage tanks.

While the manure suction truck went to other farms, several experts squatted next to the small pond. Although there was sediment, the water surface gradually became clear after a while of sedimentation.

After pouring a handful of water, Xiao Dongming smelled it and found no serious odor. Even if there was a smell, it was emanating from the farm itself, not from the water.

Others came to the same conclusion.

This model of pollution control and water recycling surprised everyone. It not only eliminated the sewage problem in the farm, but also reduced the water consumption in the farm.

Even if the pool evaporates and infiltrates, it can reduce water consumption by at least half.

Although Pengcheng itself is a modern city, there are also urban-rural fringes, as well as large and small breeding farms.

Although management is relatively strict, sewage discharge from some small farms is still a headache.

If Shanmei's model can be introduced, it would be a good idea.

With a notebook and pen in hand, Li Jiye examined the situation and recorded the parts he thought were useful.

That afternoon, a group of them went straight to Guizhuling Industrial Park. After identifying themselves, the factory director Huang Guotong came out to greet them personally.

On the other hand, the staff of the suction truck in the past two days also reported some situations to the safety department, saying that a group of people were observing their suction truck.

Based on Huang Guotong's report just now, the Ministry of Security quickly analyzed the other party's intentions. It was probably an official inspection team from Pengcheng.

Lin Baijie instructed Huang Guotong to entertain the other party well and reported the matter to Huang Xiuyuan.

In this regard, Huang Xiuyuan just let Lin Baijie act according to the situation. There was no need to be too enthusiastic, so as to take the initiative.

After all, taking the initiative to deliver something to someone's door and visiting someone's door are two different situations. Things that are too easy to obtain will always give people the illusion of being cheap.

Li Jiye and his party who visited Guizhuling Industrial Park were deeply shocked after entering the second and third phase factory buildings.

In particular, the five experts Xiao Dongming had mixed emotions, ranging from excitement to frustration.

After borrowing the factory's simple laboratory, they conducted a rough laboratory test on the quality of the water treated by the factory and found that the water was already pure water.

It is actually very simple to test whether it is pure water. Even if there is no lens electron microscope, you can still use simple methods to detect it.

One is to electrify, pure water is a poor conductor of electricity.

Another method is the supercooling method. Calm pure water will not freeze even if it is below zero degrees Celsius. This kind of water is called supercooled water. Because pure water lacks condensation nuclei (impurities), it freezes in a calm state. , pure water below zero will not freeze.

Through these two methods, Xiao Dongming and others basically determined that the water was pure water.

But what Li Jiye saw was a little different.

What he saw was rapid gas production, pure water, organic fertilizer, and deep recycling of pollutants.
