The advection sedimentation / immersion type ultrafiltration integrated water treatment device comprises an advection sedimentation tank, an immersion type ultrafiltration membrane assembly, a membrane assembly supporting tool, an ultrafiltration water outlet pipe, an ultrafiltration water outlet valve, an ultrafiltration sucking pump, an online vacuum pressure sensing device, an ultrafiltration backwashing valve, an ultrafiltration backwashing pump, a bubble diffusing device, an aerating pipe, a gas flow meter, an aerating valve, an aerating pump, a steady flow plate, a mud collecting tank, a perforation mud discharging pipe, a mud discharging valve and a sawtooth-shaped backwashing overflow weir, wherein one end of the ultrafiltration water outlet pipe is communicated with the immersion filtration membrane assembly, the other end of the ultrafiltration water outlet pipe is communicated with the ultrafiltration water outlet valve, the ultrafiltration water outlet valve is connected with the ultrafiltration sucking pump, one end of the aerating pipe is connected with the bubble diffusing device, the other end of the aerating pipe is connected with the aerating valve, and the mud discharging valve is arranged at one end of the perforation mud discharging pipe, outside a tank. The advection sedimentation / immersion type ultrafiltration integrated water treatment device is mainly applied to the field of water treatment.

Description

technical field [0001] The invention relates to an ultrafiltration integrated water treatment device. Background technique [0002] With the rapid development of the economy, the pollution of drinking water sources in my country is becoming more and more serious; at the same time, the quality standards of drinking water in my country are constantly improving, and conventional treatment processes are often difficult to meet the safety requirements of water supply. As a green physical separation technology, ultrafiltration technology is known as the water treatment technology of the 21st century. It can achieve efficient removal of particles, colloids, bacteria, and even viruses, and effectively ensure the safety of drinking water. However, the current ultrafiltration technology is mainly used as an independent process unit after conventional coagulation, sedimentation, and sand filtration. This will increase the infrastructure investment of water treatment structures on the o...
