Abstract

The invention provides a membrane cleaning system. According to the invention, pipelines behind cleaning circulating pumps of all membrane cleaning circulating systems communicate with each other, soa plurality of the cleaning circulating pumps can be used for pressurized cleaning of one membrane module, and thus, cleaning pressure with a larger selection range is provided in the process of cleaning one membrane module, the cleaning pressure is improved, and cleaning efficiency and cleaning effect are improved; the pipeline behind the cleaning circulating pump of the membrane cleaning circulating system positioned at the tail end of a liquid supply pipeline is connected with an inlet of a liquid supply tank, so emptying of the pipeline from the liquid supply tank to a cleaning circulatingtank is achieved; and discharged water is supplied to the liquid supply tank through the cleaning circulating pump, so emptying of the whole pipeline is achieved, the situation that residual cleaningliquid in the pipeline influences the temperature and pH value of cleaning liquid in a subsequent cleaning process is prevented, and therefore, membrane cleaning effect is improved.

Description

technical field [0001] The invention relates to the technical field of membrane pollution treatment, in particular to a membrane cleaning system. Background technique [0002] In the existing industrial production process, it is usually necessary to use membrane filtration technology. The key to the application of membrane technology is to solve the problem of membrane fouling, and the most basic method to solve the problem of membrane fouling is membrane cleaning. At present, the membrane systems generally used in industrial production will be polluted to varying degrees with the prolongation of operation time, and the membrane flux will gradually decrease, thus affecting the use effect of the membrane. The existing membrane cleaning system has a poor cleaning effect on the membrane. Contents of the invention [0003] The embodiments of the present application provide a membrane cleaning system to solve the technical problem that the existing membrane cleaning system has...
