AI Technical Summary
In MBR integrated wastewater treatment equipment, after wastewater enters the MBR tank, solid pollutants form a filter cake layer on the membrane surface, which leads to a decrease in membrane flux and affects treatment efficiency.
The wastewater solid pollutant treatment component includes an internal wastewater tank, a solid-liquid separation tank, a screw rod, and a servo motor. The screw rod rotates under the drive of the servo motor, pushing solid pollutants toward the solid discharge pipe. They are initially separated through the filter slots, and then further intercepted by a fine filter screen to ensure that the water entering the membrane separator is purer. The fine filter screen is cleaned regularly to reduce the fouling and clogging of the membrane separation component.
It improves the overall efficiency of wastewater treatment, reduces the risk of fouling and clogging of membrane separation components, and ensures the stability of the membrane separation process and the excellent quality of effluent.
