More Information
Summary:This invention provides membrane bioreactor with powdered zeolite addition, belonging to the technical field of water treatment, the reactor comprises a reaction tank, in which the added powdered zeolite is located, and a PLC controller is arranged outside the reaction tank and connected with the highest water level sensor, the lowest water level sensor and the outlet water suction pump respectively. The invention adds the modified powdered zeolite into the reactor, and makes full use of the complementary functions of adsorption, ion exchange, biodegradation and membrane filtration of the powdered zeolite, it especially solves the problem of poor removal effect of polar micromolecule organic matter and ammonia nitrogen by membrane bioreactor at low temperature. The invention is mainly applied to the treatment of micro-polluted source water.
