What kind of presentation will the concept of the traditional "grain reincarnation" combine with modern green technology?

In response to the country's call for the "toilet revolution" as a major people's livelihood event, the environmental protection dreamer team led by Mr. Liu Dongliang, a teacher of Zhengzhou Light Industry University, has developed a new model of circular development of urban and rural public toilets. Native

"Subtraction": Make public toilets without water, no pipe, no smell, no odor, no odor

On August 1, Tianjian Lake Park, located in the Zhengzhou High -tech Zone, attracted a stream of citizens. Near the bridgehead of the east side of the lake, several green trees surrounded a demonstration site of an ecological public toilet, and the "grain cycle toilet" written on the roadside sign was noticeable.

From the front, there are no two -way public toilets in the scenic area. The only difference that can be seen in the toilet is that the squats on the ground are designed with dung and urine separation. There is not a water punching or plastic bag under the stool area, but a flat conveyor belt. It will be transmitted to the smart biological warehouse at the back of the public toilet. Because there is a new air system for negative pressure at any time, the entire public toilet cannot be smelled.

"The beach not far from the front is an Internet celebrity punching place. As soon as it arrives on holidays, there are tens of thousands of people. Since the trial operation of this public toilet demonstration site in April this year, thousands of people have solved the need for toilet the toilet every day at the peak, and it has always maintained it. The high -quality clean environment has achieved our goal perfectly. "Hou Qinzhong, the head of the Tianjian Lake Park Management Office of Zhengzhou Urban Management Bureau, told reporters.

What makes him more satisfied is the "saving" of public toilets in construction and management. "This kind of water -free toilet does not need to excavate the water pipe discharge system. Just pull the root wires, and then give the handwashing the root water pipe. The daily cleaning is responsible for the professional cleaning company.

As a full -time cleaning personnel of the demonstration site, Chen Jing, an employee of Henan Wasi Lan Environmental Technology Co., Ltd., praised the work experience for a few months: "I have been responsible for ordinary water -type public toilets before. Busy until late. It's enough to clean it once a day or two. The preliminary feces that have been treated at the scene will be collected every two or three months. "

"We have calculated that such an ecological public toilet can reduce operating costs of more than 50%and about 80%of labor costs." Liu Chuanxue, general manager of Henan Watana Environmental Technology Co., Ltd. The team cooperation has successfully realized the industrialization of the "no sewer dung urine distributed circular toilet system", which can be widely used in scenic spots, stations, shopping malls, streets and other dense areas and villages.

"Add Fa": Let dung urine become available treasures that can be available

If you only look at the front -end user experience, similar ecological public toilets at home and abroad can also achieve good results. However, the "depth value -added treatment" mode that starts and runs through the middle and back end is a different key to the "Graphite Reincarnation toilet" model.

Teacher Liu Dongliang showed a few plastic bags to reporters, which was the terminal product successfully extracted by the R & D team in the laboratory:

Several bags of particles of particles are crude proteins extracted by the intellectual biological response warehouse for harmless treatment, which can be used as a breeding and feed for replacement of fish powder;

Two bags of pale yellow powder are biological enzymes extracted from pure urine, which can be used as raw materials or high -end fine chemical materials for biopharmaceuticals;

There are also a few small bottle of black liquid. It is a high -end liquid organic fertilizer that uses dung slag and urine processing. It can be used to cultivate high -end fruits and fruits with good tastes. , High -end products can be sold to more than 20,000 yuan per ton ...

"Pole urine sewage contains a large amount of nutrients such as nitrogen, phosphorus, potassium, etc., which is essentially a very rich treasure." Liu Dongliang said that the ancient labor people had already mastered the original dung urine cycle utilization technology, but in modern industrial industry In society, the popularity of water -rushing toilets blocked the cycle of urban and rural organic matter.

There are many significant advantages of water -rushing toilets, but their disadvantages are also increasing. On the one hand, it wastes a lot of water resources. After mixing with various harmful substances, it becomes sewage sludge, becoming one of the important sources of environmental pollution, and the cost of processing sewage sludge is high. On the other hand, the organic matter of fecal urine is difficult to realize the return to the field, and the agriculture that loses the supply of nutrients can only be fully shifted to industrialization. Due to excessive application of chemical fertilizers, it is easy to cause problems such as soil board and crop quality.

"Now that through the green circulation technology, we have allowed the traditional Chinese" grain reincarnation "concept to finally re -form a sustainable ecological 'circle' in the new era." Liu Dongliang proudly introduced that the scientific research team has developed a full set of mature maturity. The deep value -added treatment technology of feces can be used to realize the recycling of the entire industrial chain of urban urinary urine.

"Since 2016, the ecological toilet project of our school has improved the four generations, and it is currently accelerating the establishment of its own 'patent pool'." Zhang Xiaojing, deputy dean of the School of Materials and Chemical Engineering of Zhengzhou Light Institute of Technology, said that the team of environmentally friendly dreamers is committed In the system research and practice of organic matter organic matter and downstream multi -industry cycle in urban toilet, the next step will be strived to formulate new industry standards.

"Multiplication method": provides "Chinese -style ideas" for the toilet revolution

Improved the sanitary conditions of the toilet is directly related to the health and environmental conditions of the people of developing countries. To this end, the United Nations proposed the "toilet revolution". Since the 18th National Congress of the Communist Party of China, my country's urban and rural areas have set off a new round of "toilet revolution". There is a "grain reincarnation hundred garden" in Zhengzhou Light Industry University. Here are the demonstrations, experiences, and communication places for nearly 20 kinds of farm toilet models, including the latest and most practical typical public toilets and farm toilets at home and abroad.

"Through the comparative study of various toilet modes, we found that the savings of water resources and the effective use of feces and urine resources are becoming a pain point that is currently urgently needed." Liu Dongliang believes that this will also become the "upgrade of the toilet revolution" in the future "Key.

For example, at the current typical non -sewer toilet technology at home and abroad, the vacuum extraction on the high -speed rail, and the common blue water rinse of some scenic spots are still mixed feces and urine mixing methods. The supercritical technology adopted decomposed dung and urine, and the early investment was very high. In some process, the microbial decomposition technology of the countryside will produce odor gases ...

"This project of the environmental protection and dream chaser has been separated from the pure separation of dung and urine at the source, to the depth value -added treatment of subsequent fecal urine, and the system technology integration and innovation of the entire industry chain is the current single technical improvement in a certain aspect. Compared with, Zhong Sujuan, deputy director of the National People's Congress and the Executive Deputy Director of the State Institute of Welding of the Provincial People's Congress, commented on this.

The advancement of new technologies will bring a significant "multiplication effect" to urban development. According to estimates, after a cities with a population level of 10 million, after public toilets have fully promoted the "grain reincarnation toilet" model, 5.2 million tons of water can be saved each year, saving 7.3 million yuan in sewage treatment fees; 230,000 tons of organic fertilizer for output, and can improve the soil 7.6 7.6 Thousands of acres.

Looking back at the history of human toilets, the earliest widespread popularity of dung and urine returning in ancient China, forming the cleanest urban public health environment and the best agricultural yield in the world at that time, and achieved the "optimal solution" of the same period; modern times; modern times; modern times. Can China closely combine the latest green technology with the concept of cycle development to find out the "optimal solution" of the new era? It is worth looking forward to.
