A method for removing phosphorus by gasification, comprises a) providing a membrane bioreactor which includes a reaction tank (2) and a membrane separation system (1); b) aerating the reaction tank (2) to control a redox potential in the reaction tank (2) to be higher than -200mV; and c) controlling a dissolved oxygen concentration around the membrane separation system (1) to be greater than 0 and smaller than 2mg/L and the dissolved oxygen concentration in the reaction tank (2) excluding the membrane separation system(1) to be greater than 0 and smaller than 1mg/L, and allowing the dissolved oxygen concentration around the membrane separation system (1) to be higher than the dissolved oxygen concentration in the rest zones of the reaction tank (2). Also provided is a phosphorus removal system by gasification including a reaction tank (2), a membrane separation system (1), a water production system, and an aeration system. |
