< 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 being treated, the sewage can meet the national A standard, mainly used for dyeing or irrigation, and the yarn is 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 > resource and energy utilization maximization and environmental pollution minimization. Reclaimed water reuse has become the core project of the textile recycling economy demonstration area.

< /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. The pollution problem that restricts the development of" a href= "http://www.91se91.com/news/index_f.asp" textile industry < /a "can be completely eradicated.

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, told reporters that at present, the construction of the textile circular economy demonstration zone has been successfully promoted, and a circular economy development mode with sewage treatment, reuse of water, 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.
