摘要
唐山市东北郊污水处理厂为东郊污水处理厂、北郊污水处理厂合并迁建而成,拟于2021年12月底建成通水。拟建入河排污口位于开平区康各庄村南、石榴河左岸,排水管为箱涵设计,最大排水流量为3.3 m3/s。本文通过计算石榴河排污口断面天然条件下与污水处理厂最大排水条件下20年一遇设计洪水位,分析了入河排污口设置对河道行洪的影响;同时分析了对河堤安全的影响和入河排污口的防洪安全。
The Northeast Suburb Sewage Treatment Plant of Tangshan City is a combination of Dongjiao Sewage Treatment Plant and Beijiao Sewage Treatment Plant, which is planned to be completed and connected to water by the end of December 2021. The proposed river discharge outlet is in the south of Kanggez-huang Village, Kaiping District, on the left bank of Shiliu River. The drainage pipe is designed as a box culvert, and the maximum drainage flow is 3.3 m3/s. In this paper, the 20-year design flood level of the Shiliu River discharge outlet section under natural conditions and the maximum drainage condition of the sewage treatment plant was estimated;the influence of the sewage discharge outlet setting on the river flood discharge and the impact on the safety of the river embankment, as well as the flood control safety of the sewage outfall into the river were analyzed.
