藻菌共生-外置式膜过滤联合石化废水处理系统及方法
摘要：
本发明公开了一种藻菌共生-外置式膜过滤联合石化废水处理系统及方法。处理系统包括推流式反应器(1)和外置式膜过滤设备(4)；推流式反应器(1)用于利用藻菌共生体系分解石化废水中的有害物质；推流式反应器(1)上设置有第一进液口(11)、第二进液口(12)和出液口(13)，第二进液口靠近第一进液口；外置式膜过滤设备(4)设置有进液口(41)、第一出液口(42)和第二出液口(43)；推流式反应器(1)的出液口(13)与外置式膜过滤设备(4)的进液口(41)连接，外置式膜过滤设备(4)的第二出液口(43)与推流式反应器(1)的第二进液口(12)连接。该处理系统占地面小、处理效率高、出水水质好、能同时稳定去除废水中氮和磷。
摘要（英）：

The invention discloses an alga bacterial symbiosis-external membrane filtration combined petrochemical wastewater treating system and method. The treatment system comprises a push-flow reactor (1) and an external membrane filtering device (4); the push-flow reactor (1) is used for decomposing harmful substances in the petrochemical wastewater by utilizing an alga bacterial symbiotic system; the push-flow reactor (1) is provided with a first liquid inlet (11), a second liquid inlet (12) and a liquid outlet (13); the second liquid inlet is close to the first liquid inlet; the external membranefiltering device (4) is provided with a liquid inlet (41), a first liquid outlet (42) and a second liquid outlet (43); the liquid outlet (13) of the push-flow reactor (1) is connected with the liquidinlet (41) of the external membrane filtering device (4); and the second liquid outlet (43) of the external membrane filtering device (4) is connected with the second liquid inlet (12) of the push-flow reactor (1). The treatment system is small in occupied area, high in treatment efficiency and good in effluent quality, and nitrogen and phosphorus in the wastewater can be simultaneously and stablyremoved.
