摘　　要：H岛位于华南滨海地区,现状排水体制为截流式合流制,岛上污水管网密度约为2.7km/km^(2),已建截流井64座。H岛污水管网水位位于管顶以上4.33~5.19 m,比正常运行水位偏高4.58~5.46 m,管网水位与潮位关系密切;污水处理厂进水COD为108.8~138.7 mg/L,BOD为49.2~63.2 mg/L,污水实际收集处理率仅为50%,污水系统效能低下。通过查阅资料及现场复核,分析了造成污水系统效能低下的原因,并提出了挤外水、强养护等针对性解决措施。Island H is located in the coastal area of South China.The current wastewater system is an interception combined system.The density of the wastewater system in the island is about 2.7 km/km^(2),and 64 interception wells have been built.The water level of the H island wastewater system is 4.33-5.19m above the pipe top,which is 4.58-5.46 m higher than the normal operating water level.And the water level of the wastewater system is closely related to the tide level.The COD concentration of the wastewater treatment plant is 108.8-138.7 mg/L,and the BODconcentration is 49.2-63.2 mg/L.The actual wastewater collection and treatment efficiency is only 50%.And the wastewater system quality and treatment efficiency should be upgraded.Through the data review and on-site check,the causes for the low quality and efficiency of the wastewater system were analyzed,and the corresponded solutions such as squeezing extraneous water and strengthening maintenance of wastewater system were proposed.
