赛得利(江西)化纤有限公司粘胶化纤废水治理去除COD、SS

CREATE_TIME:2019-01-08 VIEWS:619

江西赛得利化纤有限公司污水处理厂为赛得利(江西)化纤有限公司年产60000吨差别化化学纤维项目的配套辅助工程,设计废水处理能力为21000m3/d,采用物化+生化处理工艺。经物化处理后的废水进入CASS池,在池中进行常规活性污泥法的生物处理,进生化池水质约CODCr 450mg/L,SS(悬浮固体) 500mg/L。出水水质需达到国家一级排放标准CODCr<100mg/L,SS<70mg/L。而粘胶纤维生产混合废水的酸性很强且富含锌盐和硫化物,治理难度较大,采用常规的物化+生化治理工艺存在运行效果不够稳定、出水水质CODCr、SS偏高等问题。

为提高CODCr、SS的去除率,稳定出水水质,九江美联环保有限公司(利蒙LLMO九江经销商)采用利蒙LLMO E-1投加治理,对污水厂的4号CASS池进行改进。
