The invention discloses a continuous coagulation-flat membrane filtering system which comprises a filtering reactor, a coagulant tank and a water storage tank. The filtering reactor is provided with astirrer, an air hole is formed in the top wall of the filtering reactor, the coagulant tank is sequentially connected with a first peristaltic pump and the filtering reactor through pipelines, the water storage tank is sequentially connected with a second peristaltic pump and the filtering reactor through pipelines, a side pipe is arranged on the side wall of the filter reactor, the outer end port of the side pipe is connected with a flat membrane, a supporting frame and a filtrate receiver through hoops, the filtrate receiver is sequentially connected with a pressure sensor, a pressure valveand a pump through pipelines and then connected with a filtrate receiving tank, a water level relay is arranged outside the filter reactor, a water level probe of the water level relay is arranged inthe filter reactor, and the water level relay is electrically connected with the first peristaltic pump and the second peristaltic pump. According to the system, the flat membrane is pumped in a negative pressure manner, continuous coagulation-flat membrane filtering can be achieved, and the system is convenient to fix, good in sealing performance and continuity and easy to disassemble and assemble.
Description
technical field [0001] The invention belongs to the field of water treatment membrane separation and relates to a continuous coagulation-flat membrane filtration system. Background technique [0002] As an advanced water treatment technology, membrane separation technology has developed rapidly in recent years. Because of its energy saving, high efficiency, economy, simplicity and convenience, and no secondary pollution, it has been widely used in water treatment for brackish and salty water. Water desalination, seawater desalination, industrial water supply treatment, pure water and ultrapure water preparation, wastewater treatment, sewage reuse, etc. Among them, the problem of membrane fouling has become the key to restricting the development of membrane separation technology, and direct filtration of raw water with membranes will cause greater filtration resistance and decrease in flux. Therefore, in practical applications, water samples are usually pretreated before mem...
