technical field

The utility model relates to the technical field of cleaning, in particular to a membrane separation device with a cleaning function.

Background technique

There are three main types of methods for advanced treatment of printing and dyeing wastewater: chemical method, physical method and biological method. Membrane separation is a kind of physical method. The advantage of using the membrane separation method is that high reliability of water treatment can be obtained because the required water purity can be easily and stably satisfied by adjusting the size of the membrane pores. However, when a fluid in which contaminants including solid components are suspended is filtered using the filter membrane module, the filter membrane is easily contaminated by the contaminants, resulting in a decrease in water permeability of the filter membrane. Therefore, the filter membrane must be cleaned periodically by removing contaminants from it. In the existing filter membrane cleaning method, the filter membranes are removed and then cleaned one by one, which is troublesome in operation and low in cleaning efficiency.
