- Abstract:
- The combined process of Chengdu Hezuo wastewater treatment plant phase Ⅲ project consists of pretreatment, MP-MBR and UV disinfection. The difficulty of this project lies in the control of TN, SS and TP. Therefore, MP-MBR process was selected as the main process to obtain better treatment performance than conventional biochemical process. In addition, the biochemical reaction process and membrane separation process were completed in different reactors, so that the operation mode of biochemical treatment and membrane cleaning, replacement and addition could be adjusted timely, and the shock load resistance of the system could be improved. The pretreatment process included coarse and fine grilles, aerated grit chamber, membrane module and regulating tank. The regulating tank was set up to solve the problem of water quality and quantity equalization in the combined treatment of domestic sewage and industrial wastewater, and realize the purpose of hydrolytic acidification. The effluent quality of the project stably met the limit specified in Discharge Standard of Water Pollutants in Minjiang River and Tuojiang River Basin in Sichuan Province (DB 51/2311-2016).
