The capacity of daily treatment of domestic sewage and industrial printing and dyeing wastewater has reached 180 thousand tons. More than 100" a target= "_blank" href= "http://www.91se91.com/" > textile < /a > printing and dyeing enterprises have entered the pipeline network, and all the textile parks have achieved centralized treatment of sewage.

Cui Lixin, Secretary of Gaoyang County Party committee, said that Gaoyang is committed to building a pilot county of energy saving and emission reduction and circular economy in Hebei province. This year, it will invest 4 billion yuan to further promote the construction of 60 thousand tons of sewage treatment plant, technical renovation project, reclaimed water utilization project, water resources recycling utilization, popular science and technology tourism demonstration project, boiler pformation and comprehensive utilization of thermal energy, etc., vigorously developing circular economy and thoroughly solving the pollution problem that restricts the development of textile industry.

< p > < strong > water pollution control first, < /strong > /p >

< p > Gaoyang as a textile County, there are all kinds of < a href= "http://www.91se91.com/news/index_c.asp" > textile enterprises < /a > more than 3300, nearly 100 textile professional villages, employing 160 thousand people, producing 3 billion 500 million towels, 30 million blankets and 24 thousand tons of wool, accounting for 38.8%, 26% and 24.7% of the total output of the country respectively.

With the rapid development of the textile industry, printing and dyeing wastewater also brings serious environmental pollution and restricts the development of the industry.

In order to fundamentally solve the worries behind the development of the textile industry, Gaoyang County puts the water pollution control in the first place in accordance with the requirements of pollution control, integration and upgrading.

< /p >

< p > according to the introduction, the Gaoyang sewage treatment plant is a municipal sewage and industrial a href= "http://www.91se91.com/news/" > printing and dyeing wastewater < /a > mixed treatment project. In November 2006, the first phase of the project started construction; in April 2009, the implementation of a upgrading project was carried out in November, and the water quality of the effluent reached the national level A standard in November through the acceptance of environmental protection in Baoding. In the same year, the two phase of the project was launched, and the commissioning process was put into operation in May 2011. The daily processing capacity of life and industrial printing and dyeing wastewater reached 180 thousand tons. In November 2011, it was accepted by the Hebei provincial environmental protection department and became the largest county level sewage treatment plant in Hebei.

< p > "Gaoyang County sewage treatment plant adopts advanced oxidation ditch + barok integrated process, which not only reduces processing costs, but also ensures stable discharge."

Wang Jidai, director of the sewage treatment plant, said that after treatment, the sewage reached the national A standard, mainly used for dyeing or irrigation, and the yarn was pure and pure.

< /p >

< p > "only about half of the cost of electricity consumption can be saved in the enterprise, and the yarn is dyed with recycled water. The yarn dyed is brighter than that of ordinary underground water. The dye can save 10% to 15%, and the water consumption is saved by 20%.

Wang Bin, manager of Shun Fa dyeing and weaving mill of Gaoyang County, regrets the tremendous benefits brought by reclaimed water to the enterprise.

< /p >

< p > < strong > how to eradication pollution? < /strong > < /p >

< p > "we must take the road of circular economy, maximize the comprehensive utilization rate of resources and energy, maximize the utilization of resources and energy, minimize the pollution of industrial waste utilization and minimize environmental pollution, and restrict the pollution problem of" a href= "http://www.91se91.com" textile industry < /a "to completely eradicate the problem.

Gao Yang county magistrate Ma Yirui firmly said.

< /p >

< p > aiming at the current situation of Gaoyang industry development, Gaoyang County has integrated the original park and redesigned the 22.29 square kilometers of textile industry gathering area, with a built-up area of 9.27 square kilometers and more than 100 enterprises, with annual sales revenue of 8 billion yuan, which has become a new engine for the development of county economy.

Among them, the textile circular economy demonstration area, planning 594.93 hectares of land, its core project - investment in 1 billion 53 million yuan of water reuse yarn dyed and high-grade towel bath dyeing and finishing project, the cumulative investment of 360 million yuan.

< /p >

Liu Zhenxin, director of the Environmental Protection Bureau of Gaoyang County, said that at present, the construction of the textile circular economy demonstration zone has been successfully promoted, and the circular economy development mode, which combines sewage treatment, reclaimed water utilization, waste heat utilization, steam printing and dyeing, and slag ash brick making, has been formed. It has been listed as the "3255" circular economy demonstration project in Hebei province.

< /p >

< p > Zhang Qingwei, governor of Hebei Province, gave full affirmation to Gao Yang's inspection in the textile recycling economy demonstration area. He demanded that Gaoyang be built as a pilot county in the province's energy conservation and emission reduction and circular economy, and that all localities should learn from Gaoyang's practice and select key areas and key drainage basins to carry out the pilot project of circular economy.

< /p >

In the pformation and upgrading of traditional industries, Gaoyang County persisted in promoting pformation and upgrading with technological pformation, and the county government set up special funds for technical pformation to support enterprises in introducing technology and updating equipment. P

In recent years, there are more than 2000 advanced sets of advanced textile equipment and more than 80% of advanced equipment investment. In the past two years, more than ten million yuan and 51 projects have been invested in the pformation and upgrading of projects, with a total investment of 6 billion 110 million yuan. It has formed the "a href=" http://www.91se91.com "cotton" textile industry represented by Hongrun, Sanli and other enterprises, represented by Rui Chun, Yong Liang and other enterprises, and the three dragon type economy represented by Rongyi, Asia and other enterprises in the blanket industry.

< p > < strong > realizing comprehensive utilization of gas, electricity, water, heat and slag < /strong > < /p >

< p > > at present, there are 236 coal-fired boilers in Gaoyang County. In the aspect of comprehensive utilization of thermal energy, this year, we will start the project of 1 billion yuan of boiler pformation and comprehensive utilization of thermal energy, and the capacity of drying sludge will reach 200 tons per day. The comprehensive utilization of gas, electricity, water, heat and slag will be realized. After the completion of the project, it will completely replace small boilers.

Liu, director of the demonstration project of Hong Run recycling economy, Gaoyang County, said that a set of scientific recycling system was also designed for sludge produced after sewage treatment. The steam produced by sludge instead of boiler fuel was used for textile dyeing or heating, and ash was used to make energy saving and environmental protection bricks.

"After the completion of the circular economy system, it can handle 58 thousand tons of sludge and 36 thousand tons of ash, and save twenty thousand tons of raw coal and save about 3 million tons of groundwater."
