Abstract

A membrane separation device with a cleaning function comprises a membrane separation unit, a water inlet pipeline and a water outlet pipeline connected with the membrane separation unit and a water suction pump communicated with the water outlet pipeline. The membrane separation unit comprises a first chamber communicated with the water inlet pipeline and a second chamber communicated with the water outlet pipeline, and a plurality of globular hairbrushes are arranged in the membrane separation unit. According to the membrane separation device with the cleaning function, the plurality of the globular hairbrushes are arranged between adjacent porous membranes in the second chamber, cleaning liquid is added into the second chamber to be reacted with the outer walls of the porous membranes by controlling a jet flow pipeline, and gas is transmitted into the second chamber by controlling a gas transmission pipeline, the plurality of the globular hairbrushes collide mutually to slightly brush over the outer walls of the porous membranes under the action of the gas; accordingly, the porous membranes are cleaned and prevented from plugging; a pressure detecting meter used for detecting pressure of the outer walls of the porous membranes is arranged in the second chamber, the cleaning process is performed when the pressure achieves a certain value.

Description

technical field [0001] The invention relates to a membrane separation device for treating industrial waste water, in particular to a membrane separation device with cleaning function and a cleaning method thereof. Background technique [0002] my country is a country with scarce water resources, and the per capita water resources account for 2500m of the total 2 , which is 1 / 5 of the world's per capita level. With the rapid development of social economy, the contradiction of water shortage is becoming more and more serious. However, my country's water consumption quota is relatively high, and the water intake per 10,000 yuan of industrial added value is 5 to 10 times that of developed countries. The industrial water reuse rate is lower than 30%, and the water treatment and water utilization rate technologies have not reached the level of moderately developed countries. The printing and dyeing industry is a "big energy and water consumer", accounting for 35% of industrial wa...
