摘要
A method for wastewater treatment with zero discharge of sludge is provided, which including: a) providing a membrane bioreactor system comprising a membrane separation system (1) and a reaction vessel (2); and b) aerating the membrane separation system (1) and the reaction vessel (2) to control a dissolved oxygen concentration around the membrane separation system (1) to be greater than 0 and smaller than 2 mg/L and the dissolved oxygen concentration in the reaction vessel (2) excluding the membrane separation system (1) to be greater than 0 and smaller than 1 mg/L. A wastewater treatment system with zero discharge of sludge includes a membrane bioreactor system, and the membrane bioreactor system includes a reaction vessel (2), a membrane separation system (1), a water production system, and an aeration system.
