Abstract

The invention provides a reinforced scrubbing system for a vertical flat-plate ceramic membrane and application of the reinforced scrubbing system. According to the reinforced scrubbing system, air flushing and water flushing are adopted in the system at the same time; scrubbing particles are driven to roll through air flushing, so scrubbing of the flat-plate ceramic membrane by scrubbing particles is reinforced; then pressure water is used for upward flushing, so the problem that the surface of the flat-plate ceramic membrane is polluted and is difficult to clean is solved. A slag discharge groove and a baffle are arranged on the upper portion of the membrane, sludge is discharged upwards after air scrubbing is strengthened, and meanwhile it can be guaranteed that scrubbing particles cannot escape in a flushing process. The problems that due to the fact that the surface of the flat-plate ceramic membrane is flat and smooth, the control effect of traditional air friction washing on membrane pollution is quite limited, and the ceramic membrane can be quickly blocked when dirt and organisms adhere and grow seriously are solved, and the system has the advantages of being high in practicability, high in technical economy, high in automation degree and the like.

Description

technical field [0001] The invention relates to the field of membrane technology, in particular to a membrane pollution cleaning system suitable for flat ceramic membranes and its application. Background technique [0002] Flat ceramic membranes are widely used because of their long life, high flux, corrosion resistance, and friction resistance. With the improvement of technology and the reduction of cost, flat ceramic membranes will be more used. [0003] However, the surface of the flat ceramic membrane is flat and relatively smooth, and the traditional air friction washing has a limited effect on the control of membrane fouling. When the growth of dirt and bio-attachment is serious, the ceramic membrane will be quickly blocked. [0004] Although frequent chemical cleaning can alleviate membrane fouling, it consumes chemicals, water, and time, which affects the efficiency of flat ceramic membranes. [0005] At present, there is still a lack of targeted physical scrubbing...
