Pneumatic de-molding type sewage treatment combined filler and matched device thereof

Abstract

The invention discloses a pneumatic de-molding type sewage treatment combined filler and a matched device thereof, belongs to the field of combined fillers, and has the advantages that in the use process, oxygen-containing gas is introduced into a hollow elastic bag rope, so that on one hand, the hollow elastic bag rope can be expanded to drive a film attaching disc silk screen to outwards extendand expand; a biofilm loose due to the pulling action, which accelerates the shedding of the aged biofilm initially, on the other hand, oxygen-containing gas is dispersed into the sewage through the gas filtering shaping pipe to form gas flow impact on the film attaching disc silk screen, so that the falling of the biological film is further promoted, the oxygen content of the sewage is increased,and the degradation efficiency of the biological film is improved; the oxygen-containing gas drives a collision ball to continuously float up and down and collide with an air filtering shaping pipe,so that the film attaching disc silk screen generates certain vibration and depth to promote falling of the biofilm, the blockage condition of the biofilm is greatly reduced through the three auxiliary demolding processes, and the continuous and efficient degradation performance of the combined filler is guaranteed.

Description

technical field [0001] The invention relates to the field of combined packing, and more specifically relates to a combined packing for pneumatic off-mode sewage treatment and its supporting device. Background technique [0002] Fillers are widely used in water treatment, whether in aerobic, facultative or anaerobic treatment processes, or integrated sewage treatment equipment, fillers are everywhere. The filler in the water treatment process usually provides a surface material (or filter material, carrier) for the growth and fixation of the biofilm. Filler is the technical core of biofilm water treatment process. It is the transfer medium of microbial biomass, microbial species, microbial activity and substances required for microbial metabolism in the biological pool. Filler is related to microbial habitat, growth and reproduction. Fillers have a significant impact on the performance characteristics and process development of biofilm processes. Therefore, the quality of t...

Problems solved by technology

[0005] However, in the existing sewage treatment fillers, some of them are not easy to form a film during use due to the large gap between the fillers, and the amount of bio-adhesion is low, while some fillers are densely distributed between the fillers and have small gaps in order to increase the amount of bio-adhesion. , but the flow resistance generated during use is relatively large, and it is not easy to remove the film (the aging biofilm is not easy to fall off), causing blockage, affecting the contact between sewage and biofilm, resulting in a decrease in the degradation performance of the filler
