广州某典型分期建设污水厂的高效调试和运行调控技术
Efficient Commissioning and Operation Control Technology for a Typical Phased WWTP Construction in Guangzhou
摘要
Abstract
The construction of wastewater treatment plants(WWTPs)by stages is the normal state of the planning and of large,medium and small cities at present.Based on the operating load rate,water quality standards,investment guarantee,system safety and other factors of WWTPs,the construction and operation of WWTPs by stages is the direction of urban WWTP construction in the future.A municipal wastewater project in Guangzhou includes expansion and bid upgrading,among them,the expansion project is 3×105 m3/d,adopting AAOA+MBR process,and the bid upgrading project is 2×105 m3/d,using modified AAO+advanced treatment process.In order to solve the problems of incomplete system function,low removal rate of total phosphorus,unclear water allocation regular pattern between multi-stage WWTPs,high energy consumption,abnormal water quality fluctuation and insufficient experience in new process safety management at the initial stage of trial operation,the first was to use temporary measures,such as using multiple high-power generators to supply main equipment by zones,using temporary blowers for biochemical aeration,and using temporary reagent tanks and laying temporary reagent tubes.To achieve the goal of water supply on schedule and discharge up to standard,the second was to optimize the process,improve the operation capacity,and gradually form a set of mature,low-energy multi-stage WWTP commissioning and regulation operation experience through influent at different points,and optimize the amount and mode of aeration,so as to finally ensure that the effluent is stable and up to standard,and ensure the safety of the regional water environment.关键词
