摘要:
成都合作污水处理厂三期工程采用预处理+多相组合膜生物反应器（MP-MBR）+紫外消毒组合工艺，其工程难点在于对TN、SS、TP的控制。因此，选择MP-MBR工艺作为主体工艺以获得优于常规生化工艺的处理效果。同时，生化反应过程与膜分离过程分别在不同反应器中完成，便于适时调整生化处理的运行模式以及膜的清洗、更换及增设，提高系统的抗冲击负荷能力。预处理阶段包括粗细格栅、曝气沉砂池、膜格栅、调节池，设置调节池是为了解决生活污水与工业废水合并处理的水质水量均化问题，同时实现水解酸化的目的。实践结果表明，该工程出水水质稳定达到《四川省岷江、沱江流域水污染物排放标准》（DB 51/2311—2016）的要求。
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).
