The invention discloses an external-pressure membrane ultra-filtration device. The external-pressure membrane ultra-filtration device comprises a raw water tank, a raw water pump, an outer shell, a water inlet, an air inlet, a center pipe, a backwashing pump, a water production tank, a cleaning water tank, a cleaning pump, an ultra-filtration membrane filter, a purified water outlet, a thick water outlet, an exhaust opening and the like. Water needing processing is fed into the raw water tank, enters the raw water pump, passes through the ultra-filtration membrane filter, enters an ultra-filtration device body through the water inlet, the air enters the ultra-filtration device body simultaneously, the water passes through the center pipe and enters the water production tank, acidification and chlorination are carried out on the water through the backwashing pump, the water enters the water production tank again, thick water discharged through the thick water outlet enters the cleaning water tank, passes through the cleaning pump, passes through the ultra-filtration membrane filter, and enters the ultra-filtration device body through the water inlet, the cycle is carried out repeatedly, finally, the thick water is discharged through the thick water outlet, and gas is discharged through the exhaust opening. The external-pressure membrane ultra-filtration device is made of any one of PVDF, PES, PS, PVC, PAN, PMMA and CA.
Description
technical field [0001] The invention relates to an external pressure device, in particular to an external pressure membrane ultrafiltration device. Background technique [0002] The water treatment products currently on the market are expensive, do not have the characteristics of sufficient exposure, strong pollution resistance, strong chemical resistance, low pressure and large flux, weak adaptability to changes in raw water quality, complicated operation and maintenance, and stable and reliable water quality. Very good and effective removal of turbidity, suspended solids, colloids, microorganisms and other indicator substances in water. Seriously endanger people's health. Contents of the invention [0003] The present invention aims at the problems existing in the above-mentioned products, and provides an external pressure membrane ultrafiltration device to solve the problems of the above-mentioned products, such as insufficient exposure, strong pollution resistance, st...
