Xian'An Builds A Town Of Green Ramie

2007, located

The total investment is more than 30 million yuan, which is in line with the national level emission standards. Why should it be put into use in 4 years?

"To protect Liangzi Lake's water environment," Tan Haihua, Secretary of the district Party committee of Xian'an District, said.

As we all know, Liangzi Lake is a national level water resources ecological protection lake and Wuhan drinking water reserve bank.

The Gaoqiao River, which flows through the Xian'an District, is a tributary of the upper reaches of Liangzi Lake. Therefore, protecting the water environment of Gaoqiao river basin is of great significance for ensuring the environmental safety of Liangzi Lake.

In recent years, in order to create "

Xian'an is the hometown of ramie in the whole country. Ramie planting and deep processing are one of the pillar industries in the whole region.

According to statistics, there are more than 20 large and small ramie degumming enterprises in the region, with an annual output of nearly 10000 tons of refined hemp, with an annual output value of nearly 300 million yuan.

With the development of the economy and the pollution problem, the degumming enterprises discharge about 3000000 tons of waste water every year. These waste water is directly discharged into the river without any treatment. PH, COD and suspended solids are more than 100 times the national standard, which not only pollutes the surrounding environment, but also poses a serious threat to the downstream Liangzi Lake waters, so it is imperative to govern them.

The news of shutting down the small degumming business has spread widely in the society.

Some people think that it is not important to develop the economy to step on the red line and hit the "edge ball".

Some people have questioned: "where is the raw material for the degumming business, where is the raw material of the hemp industry? How much is the loss of the industrial output value of nearly 3 hundred million?"

In spite of this, the district and district governments have resisted resistance from all sides, weighed the pros and cons, clarified the right and wrong, and unified the whole region's thinking from top to bottom to scientific development: rather slow development, and at the expense of the environment, the small workshop type degumming enterprises have serious pollution and must be resolutely closed down.

Immediately after that, the district set up a "small degumming and cleaning up special action" leading group, formulated special action plans, and adopted the overall linkage method.

Up to now, 21 small workshop degumming enterprises which do not have the ability to control pollution have been shut down. This has completely reversed the situation of small workshop degumming enterprises everywhere and sewage crossflow, and the quality of water environment has recovered.

In recent days, the seven group of Xiangpu village, Xiangyang lake, Xian'an District, has been extremely busy, because the first eco environmental protection ramie degumming Center - Xianning ramie degumming center is under construction.

The center has a total investment of 120 million yuan, covering an area of 60 mu, and uses the microbial degumming patent technology jointly developed by Hubei elite Textile Group Company and Huazhong University of Science and Technology.

Starting next year, the city's ramie degumming enterprises will focus on degumming, centralized pollution control and unified emission.

On the 15 day, at the construction site of ramie degumming center in Tianyuan Textile Co., Ltd., Hubei, the reporter saw that more than 130 workmen in charge of welders, masonry workers and reinforcement workers were working hard. The main works of 8 biochemical ponds were basically completed, and the iron nets of the strains were also erected.

According to Xu Xingding, director of construction, the project invested 60 million yuan, the design capacity for handling sewage was 5000 tons, and started in early 2009. The main project is expected to be completed before the Spring Festival. It will start trial operation next year and will be put into operation in June next year.

"The degumming sewage near 100 DEG C first flows into the cooling pool with 8000 cubic meters of storage capacity, and then pumps into the coagulation sedimentation tank. After the hydrolysis acidification pond, the one or two stage biochemical tank and the flotation tank, and so on, the final sewage inlet COD value reaches below 100, which conforms to the national first level discharge standard.

Xu Xing introduced the way vigorously.

It is understood that once Xianning ramie degumming center is put into use, the essence of ramie degumming sewage treatment plant will immediately "move", threatening pollution hazards of Gaoqiao River and Liangzi Lake will disappear completely.

Hu Zude, chairman of Hubei Jinghua Textile Co., Ltd. wrote to reporters: at present, the cost per ton of industrial sewage treatment is 2.3 yuan. The company produces about 2800 tons of degumming sewage every day, plus management fees. Once the degumming center sewage treatment project is put into operation, the daily running cost will be more than 10 thousand yuan.

"Only by making up your mind and completely eliminating hidden dangers can we realize the healthy development of enterprises. The gold lettered signboards of Xianning's Ramie village can really start!" Hu Zude said.

Strive for "zero pollution"

How to calculate "zero pollution"?

15, in the essence of ramie degumming sewage treatment plant, the reporter witnessed the process of degumming sewage from black to clear: like a sauce like black water slowly flowing into the water outlet, and then from the outlet, it is already a bottoming water. The online automatic monitor shows that the COD value is 46, far lower than the national level emission standard 100.

Yang, a chemist, said that the equipment was monitored in real time for 24 hours a day, and the main indicators such as pH and COD were clear at a glance.

Wherever there is Internet, you can check the monitoring data at any time.

Hu Guangwang, the head of the ramie degumming sewage treatment plant, pointed to two pumping pumps not far away, saying that in order to reduce the discharge amount, the company could recycle the treated sewage again. At present, more than 1000 tons of waste water can be recovered and recycled, accounting for more than 40% of the emissions.

According to the relevant person in charge of the Environmental Protection Bureau, in order to ensure "zero pollution", the district not only requires the factory to move away from Gaoqiao River Basin, but also helps enterprises improve their production processes and carry out technological research and development, so as to minimize environmental pollution.

Hu Zude told reporters: with the help of the environmental protection department, the company has successively worked with Wuhan University, Jiangsu Yixing environmental protection company, Huazhong University of Science and Technology and other scientific research departments, and successfully developed microbial wastewater treatment technology in 2010.

The technology is free from dependence on heavy polluting raw materials such as sulphuric acid and liquid chlorine. It is replaced by pollution-free microbial materials and greatly improves the efficiency of sewage treatment.

This technology not only obtains national patent, but also fills the blank of technology in the same industry in China.

"At present, we are carrying out two technical tackling problems, one is nanofiltration advanced treatment technology, the other is improving the technology of waste water recovery and utilization.

Once put into use, not only can fully clean production be achieved, but the utilization rate of waste water is expected to reach 100%, and then the goal of "zero pollution" can be truly realized! "Hu Zude confidently said.
