摘要
采用除油/生物处理/混凝沉淀工艺处理焦化废水,经过近一年的实际运行表明,该工艺在进水COD浓度为1500~7000mg/L、NH3-N浓度为300~3000mg/L的条件下,对COD去除率〉95%、出水NH3-N稳定在10mg/L以下(去除率〉98%),出水水质达到《污水综合排放标准》(GB8978-1996)的一级标准。
One year practical operation shows that under influent COD of 1 500 -7 000 mg/L and NH3 -N of 300 -3 000mg/L, the removal efficiency of COD is higher than 95% and NH3 -N residual in effluent is less than 10 mg/L ( i. e. the removal efficiency is higher than 98% ) by using deoil/ biotreatment/coagulation/sedimentation process to treat coking-plant wastewater. The effluent quality satisfies the class-I requirement of Integrated Wastewater Discharge Standard (GB 8978 -1996 ).
