[0002] Ceramic membrane filtration is a kind of liquid purification technology based on nanoscale microporous structure, and high-efficiency solid-liquid separation is realized by membrane element made of ceramic material. After the ceramic membrane filters the raw liquid, the dirt will be left on the ceramic membrane, at which time it needs to be cleaned. The cleaning method of the ceramic membrane is mainly divided into physical cleaning and chemical cleaning.

[0003] At present, the cleaning of the ceramic membrane is mainly in the form of physical cleaning, and the physical cleaning is divided into backwashing method, gas-liquid mixed oscillation cleaning, isobaric flushing (back pressure cleaning) and other physical methods. The backwashing method mainly utilizes the cleaning liquid to be injected into the ceramic membrane in the direction, to form the reverse circulation flow mode, to realize the cleaning effect of the ceramic membrane.

[0004] However, due to the different situations of the raw liquid filtered in the ceramic membrane, the required cleaning degree is also quite different. For example, after the industrial raw liquid and the food-grade raw liquid are filtered in the ceramic membrane, the backwashing conditions of the two are different, that is, the ceramic membrane used for filtering the food-grade raw liquid not only has cleaning requirements for the macroscopic dirt, but also has requirements for the microscopic bacteria killing. However, the current backwashing device of the ceramic membrane can only realize the killing by adding disinfectant into the cleaning liquid. However, the disinfectant itself has certain harmful effects on the human body, so there is still a certain risk of harm when the disinfectant is used for killing. INVENTION CONTENTS
