Abstract

The invention relates to the technical field of sewage treatment, and specifically relates to a cleaning device and a cleaning method for a ceramic flat sheet membrane component. The cleaning device provided by the embodiment of the invention comprises an accommodating mechanism, a fixing bracket, an air blower, a first water inlet pipe and an ozone generator, a liquor is injected into an accommodating cavity first in use, the dirt on the ceramic flat sheet membrane component is soaked by the liquor, and is softened and separated, then the air is introduced to scour the dirt, the dirt cleaningefficiency is higher; the ozone is introduced into the ceramic flat sheet membrane component through an ozone generating mechanism, the pollutant in an inner channel and an aperture of a ceramic membrane is oxidized and degraded from inside to outside, the cleaning effect on the dirt at the inner part of the ceramic flat sheet membrane component is better, then tap water is used to flush back from the inner part to the outer part of a ceramic membrane sheet, the pollutant blocked in the aperture of the membrane is thoroughly removed, the membrane flux restoration effect is better, the cleaning efficiency is higher, and the cleaning time is reduced by a half or more.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a cleaning device and a cleaning method for a ceramic flat membrane module. Background technique [0002] MBR (MembraneBio-Reactor-membrane bioreactor) is a new type of water treatment technology that combines a membrane separation unit with a biological treatment unit. It replaces the secondary settling tank with a membrane module to maintain a high active sludge concentration in the bioreactor and reduce Wastewater treatment facilities occupy less land and by keeping the sludge load low, thus reducing the amount of excess sludge. Compared with the traditional biochemical water treatment technology, MBR has the characteristics of high treatment efficiency, good effluent quality, compact equipment, small footprint, easy automatic control, and simple operation and management. [0003] Flat ceramic membrane has the advantages of good chemical stability, acid and alkali re...
