- 摘要:
- 某镇纺织企业中水回用工程服务于7家喷水织机企业，设计处理规模6 500 m3/d，采用格栅+混凝气浮+曝气生物滤池处理工艺，通过20%中水与污水厂的尾水交换、含油污泥离心脱水将油类留存于泥饼的方式，消除中水回用的污染物循环富集问题。实践证明，喷水织机废水经该工艺处理后，中水水质达到了喷水织机用水要求，大大减轻了原集中处理污水厂的水处理负荷，使污水处理厂出水水质稳定达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级A标准。
- Abstract:
- A reclaimed water reuse project with designed treatment capacity of 6 500 m3/d, which serves seven water-jet loom enterprises in a county, adopts the process of screen, coagulation flotation, and biological aerated filter. Twenty percent of the reclaimed water is exchanged with the effluent of the wastewater treatment plant(WWTP), and the oily sludge is centrifugally dehydrated to eliminate pollutant enrichment during reclaimed water cycling. Practice has proved that the quality of reclaimed water treated by this process can meet the demand of water-jet loom, which greatly reduces the water treatment load of the original centralized WWTP. Thereby the effluent of the WWTP reaches the discharge requirement of first level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).
