摘要
针对某印染厂的废水水质特点,设计相应的预处理改造方案,对其高有机磷阻燃废水和含聚乙烯醇退浆废水分别进行预处理,以保障生化处理系统的稳定运行。同时,为了保障外排水稳定达标,对二沉池出水进行深度处理。工程改造后,运行稳定,达到了相应的污水排放要求。
According to the water quality characteristics of the waste water from a printing and dyeing plant, the corresponding pretreatment and transformation scheme was designed to pretreat the high organophosphorus flame retardant wastewater and the polyvinyl alcohol-containing desizing wastewater respectively, so as to ensure the stable operation of the biochemical treatment system.At the same time, in order to ensure that the external drainage reaches the standard stably, the effluent from the secondary sedimentation tank was treated deeply. After the project transformation, the operation was stable and the corresponding sewage discharge standard was reached.
