预处理系统-氧化沟工艺处理化纤废水

Treatment of chemical fiber wastewater using pretreatment system-oxidation ditch

化纤废水CODcr、BOD5、SS、S2-、Zn2+浓度都很高。采用物化预处理系统—氧化沟工艺处理某化纤企业废水后,效果明显,出水各项指标均可达到《污水综合排放标准》(GB8978-1996)中的一级排放标准。同时最大程度地降低了工程投资和运行成本,减少了整个设施的占地面积。

The concentration of CODcr,BOD5 ,SS,S^2- and Zn^2＋ are quite high in chemical fiber waste water. After the pretreatrnent system- oxidation ditch treatment,the effect of the technology is so obvious that the quality of the treated wastewater can meet the require- merits of the Comprehensive Effluent Discharge Standard （GB8978 - 1996）. Meanwhile engineering investment, run eost and occupied land area are reduced.
