Abstract

The invention relates to a soaking thin-walled plate frame membrane filter, which consists of one or a plurality of thin-walled plate frame membrane filter sheets and an aeration device below the filter sheet. The membrane filter sheet consists of a thin-walled panel, a conduction part and a filter membrane, all of which are bonded together. The invention is characterized in that at least two support strips are respectively arranged along two sides to form an asymmetrical framework on one surface of the invention, the vertical asymmetrical frames pressures each other closely to form a membrane chamber and two thin metal or plastic reinforcing strips are further arranged along two sides to be used as support. The soaking thin-walled plate frame membrane filter provided by the invention can be soaked in an original / waste sink and filters impurity in water, the aeration device is used for blocking reduction of the membrane and therefore, stable water production, bacteria filtering and reduction of slit index and turbidity can be realized.

Description

technical field [0001] The invention relates to a soaking type membrane filter which is composed of a thin plate and frame filter membrane and an aeration and backwashing device, especially a kind of thinner thickness, lighter weight and certain strength, which can be backwashed and used for backwashing. The immersion type thin plate frame membrane filter with an asymmetric frame to prevent the filter membrane from breaking. Background technique [0002] Generally, when the turbidity of urban wastewater or industrial wastewater is less than 1NTU, it must be purified by coagulation, sedimentation, filtration and general ultrafiltration or microporous filtration treatment equipment. During the purification process, not only coagulants must be added, In addition, bulky coagulation tanks, sedimentation tanks, sand filtration equipment, and ultrafiltration or microporous filtration equipment are required, which not only requires large processing equipment and complicated processi...
