摘  要：针对工业密集型城镇污水处理厂应对突发性进水异常能力不足的问题，提出了在污水处理厂前端设置应急处理系统的解决方法。该文以南方某区综合污水处理厂为例，通过对历史进水异常事件分析，发现来水中工业废水含量占比较大和水质复杂多变，同时水厂现行工艺存在难以准确掌握和控制来水的弊端。设计采用以预警监测单元和应急调蓄单元组成的应急处理系统，提升了污水处理厂应对异常进水能力。

Abstract：Aiming at the problem that the industrial intensive urban wastewater treatment plant has insufficient ability to deal with sudden abnormal inflow， the method of setting emergency treatment system at the front end of wastewater treatment plant is proposed. Taking a comprehensive wastewater treatment plant in South China as an example， through the analysis of the historical abnormal inflow events， it is found that the industrial wastewater content of abnormal inflow is relatively large and the water quality is complex and changeable. At the same time， the current process of the water plant is difficult to accurately grasp and control the inflow. An emergency treatment system composed of early warning monitoring unit and emergency storage unit is designed to improve the ability of sewage treatment plant to cope with abnormal water inflow.

Key Words：Urban wastewater treatment plant; Sudden abnormal water inflow; Industrial waste water; Emergency treatment

近年来，部分工业密集型城镇污水处理厂受突发性异常进水冲击事件时有发生，进水中可能含有工业废水，工业废水污染物浓度高、毒性强、可生化性差，难降解有机物含量高[1-2]，短期内可导致生化系统崩溃，生化系统恢复需要数十日，对污水厂的正常运行和出水造成了恶劣的影响[3]。城镇污水处理厂面对突发性异常进水的应急措施，一般采用前端处理或末端治理的方法。前端处理一般选择在污水厂前端设置调节池或缓冲池，如美国Snapfinger污水处理厂[4]在集水井前增设了调节池;哈尔滨松北集乐污水处理厂[5]和辽宁某氟化工产业园区污水处理厂[6]在粗格栅后设置调节池;德国Hattingen污水處理厂[7]在沉砂池后设置了与初沉池平行的缓冲池;某制革园区污水处理厂[8]在粗格栅后设置由事故水调节池和絮凝沉淀池组成的事故应急处理系统。……
