摘　　要：件杂货码头根据货种的不同,产生的污水性质及浓度也不尽相同。袋装货物码头及堆场产生的污水主要为初期雨水,无包装货物如木材、石料堆场产生的污水主要为径流雨污水。初期雨水及后期洁净雨水可通过电动闸门或自然切换的方式进行分流,设置初期雨水池收集,后期洁净雨水排放至雨水系统,径流雨污水由调节沉淀池收集。初期雨水及径流雨污水可根据污染物的性质采用气浮或混凝沉淀的处理工艺,如有回用要求时还应增加过滤消毒的处理工艺。The nature and concentration of sewage produced are different according to different cargo types in the cargo terminal.The sewage produced by bagged cargo terminals and storage yards is mainly initial rainwater,while that produced by unpacked cargo storage yards such as wood and stone is mainly runoff rainwater.The initial rainwater and the later clean rainwater can be divided by electric gate or natural switching.This paper collects the initial rainwater in the initial rainwater tank and discharges the later clean rainwater into the rainwater system.The runoff rainwater sewage is collected in a regulating sedimentation tank.According to the nature of sewage,the initial rainwater and runoff rainwater sewage should be treated by air flotation and coagulant sedimentation respectively.If there are reuse requirements,the treatment process of filtration and disinfection shall be added.
