- Abstract:
- Plant-network integration is to ensure the safety and efficient operation of an urban drainage system. Based on the factors of sewage volume, water quality and water level, the integrated construction and coordinated operation of wastewater treatment plant and drainage pipe network is the development direction of urban drainage system in the future. The design treatment capacity of a comprehensive municipal wastewater treatment project in Jiangxi is 1.5×104 m3/d, and the process consists of multi?mode A/A/O, anoxic tank and MBR. To solve the problems such as low wastewater quantity and pollutants concentration in the initial stage of operation, high total phosphorus in the effluent, sudden increase of wastewater quantity and decrease of pollutants in the influent in rainy season, two measures were carried out as follows: first, the combination of wastewater quality and quantity investigation in the sewage pipe network and step commissioning of the wastewater treatment plant; second, linkage adjustment of the plant and network, addition of external carbon source and optimization of the dosing equipment. Finally, the commissioning and operation of the wastewater treatment plant was qualified, and successful experience for plant?network integration commissioning and operation was summarized.
