摘要
借鉴含铜废水预处理设施脱氮升级改造经验,将化工废水接入含铜预处理设施,改造采用“水解酸化+A/O+PACT+混凝沉淀”处理工艺,在保证其他指标去除效果不受影响的情况下大幅提升COD去除能力,有效利用了区域废水处理设施富余能力,工程实际运行结果满足江苏省对化工废水排放相关要求。可为有类似情况的区域提供借鉴。
Based on the experience of denitrification upgrading and transformation of copper-containing wastewater pretreatment facilities,the chemical wastewater was connected to copper-containing pretreatment facilities,and the change adopts the treatment process of"hydrolysis acidification+A/O+PACT+coagulation sedimentation",which significantly improved the COD removal capacity and effectively utilized the surplus capacity of regional wastewater treatment facilities while ensuring that the removal effect of other indicators is not affected.The actual operating results of the project meet the relevant requirements of Jiangsu Province for chemical wastewater discharge.It can provide a reference for regions with similar situations.
