Design Case of a Fully Underground WWTP in Foshan City
摘要
Abstract
[Objective]The current effluent of a wastewater treatment plant(WWTP)in a certain area of Foshan City cannot meet the discharge water quality requirements of the Action Plan for Prevention and Control of Water Pollution.At the same time,for the purpose of cooperate with the construction of the north gateway center of central axis planned by the Foshan Municipal Government and reduce the impact of the WWTP operation on surrounding environment,a WWTP in a certain area of Foshan City has been upgraded and constructel into a fully underground WWTP.[Methods]The comprehensive treatment capacity of WWTP is 100 000 m3/d,and the effluent is subject to the Level A standard of the Pollutant Discharge Standards for Urban Sewage Treatment Plants(GB 18918-2002)amendment list(released in 2006),the stricter of the Guangdong Province local standard Discharge Limits of Water Pollutant(DB44/26-2001)and the Fenjiang River Basin Water Pollution Discharge Standards(DB44/1366-2014).Among them,ammonia nitrogen implements the standard 1.5 mg/L for Level Ⅳ water in the Environmental Quality Standards for Surface Water(GB 3838-2002),and reserves the underground facility space for the water to be upgraded to Level Ⅳ water standard.The water treatment process adopts"pretreatment+combined anaerobic/anoxic/aerobic(AAO)biochemical process-moving-bed biofilm reactor(MBBR)+magnetic coagulation high-efficiency sedimentation tank+ultraviolet contact disinfection channel(supplemented with sodium hypochlorite)",the deodorization process adopts"biological deodorization+ion deodorization+whole process root deodorization",and it will introduce the application of smart WWTP for the first time.[Results]Since its operation,the effluent and atmospheric energy of this project have remained stable and meet the standards,compared with the original factory,it has released about 64 000 m2 of green space as a municipal park,achieving maximum land use while ensuring smooth processes,convenient transportation,and good landscape visual effects,the application of smart WWTP has also enhanced the industry's intelligent competitiveness.[Conclusion]This project is the first fully underground WWTP in Foshan City,a demonstration project in Foshan City,and also selected as the benchmark plant for the third phase of"Double Hundred Leapfrogs"wastewater treatment.This paper mainly introduces its design scheme,process flow,equipment parameters and operation situation,etc.,provides reference for similar projects.关键词
