Existing Situation and Experience of Rural Domestic Waste water Treatment in Guangzhou
摘要
Abstract
[Objective]In order to get insight into the existing situation of rural domestic wastewater treatment in Guangzhou,summarize and promote effective treatment experience,and provide reference for other areas to carry out new rural construction.[Methods]The construction,operation and maintenance management and capital investment of rural domestic wastewater treatment project were investigated and analyzed by site investigation,data review,data statistics and water quality[chemical oxygen demand(CODCr),ammonia nitrogen,total phosphorus]analysis,wastewater collection and the operation effect of various treatment process.[Results]The results showed that Guangzhou selected the governance mode according to local conditions,preferred the engineering procurement construction(EPC)mode for construction,publicly invited third-party units to carry out operation and maintenance work,continued construction and operation and maintenance capital investment,and used information management means,and achieved remarkable results.More than 8 500 kilometers of wastewater pipe networks and 2 600 rural domestic wastewater centralized treatment facilities with a total treatment capacity of 176 000 m3/d had been built.There were some problems in wastewater collection and storage,such as water seepage,pipe network quality defects,rainwater and waste water confluence,etc.The concentrated treatment mainly used anaerobic pond+constructed wetland,anaerobic pond,membrane biological reaction(MBR)process,and anaerobic/anoxic/aerobic(AAO)process,accounting for 46.9％,27.9％,10.6％,12.2％respectively.The processing scale was below 50 m3/d.The order of operation and maintenance cost was MBR＞AAO＞anaerobic tank+constructed wetland＞anaerobic tank.The covering area rank was anaerobic pool+constructed wetland＞anaerobic pool＞AAO＞MBR.The removal effect of CODCr,ammonia nitrogen and total phosphorus was different,and the effluent quality of anaerobic tank was the worst.[Conclusion]In the process of rural domestic wastewater treatment,attention should be paid to the quality of pipe network construction and operation and maintenance management,strengthen capital investment,and select the appropriate treatment process according to operation and maintenance cost,land area,water quality and quantity,etc.关键词
