碱减量印染废水处理工程实例

Practice on wastewater treatment from alkali peeling facility

采用厌氧水解/好氧生化/混凝沉淀法的组合工艺处理碱减量印染废水,工程运行结果表明:进水CODCr为2 263 mg/L,SS(悬浮物)为183 mg/L,色度为683倍时,处理后出水CODCr为166 mg/L,SS为7 mg/L,色度为76倍,可达到GB4287—2012《染织纺整工业水污染物排放标准》的现有企业间接排放标准要求。

Alkali peeling wastewater is treated by the combined process of anaerobic hydrolysis, aerobic biochemical and coagulation precipitation. The operation results show that at the qualities of water inlets with CQD cr 2 263 mg/L,SS （suspended solids） 183 mg/L and chrominance 683 times, the water outlets feature COD cr 166 mg/L, SS 7 mg/L and chrominance 76 times, which can meet the requirement of GB 4287--2012 discharge standards of water pollutants for dyeing and finishing of textile industry.
