Problems solved by technology

[0005] Among 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-adh

Abstract

The invention discloses a wire-drawing gathering-scattering type combined filler for sewage treatment, and belongs to the field of combined fillers. The wire-drawing gathering-scattering type combined filler for sewage treatment comprises a fixed rope, a semi-elastic movable rope and a plurality of uniformly distributed rhombic filler bodies, wherein the fixed rope and the semi-elastic movable rope sequentially penetrate through the rhombic filler bodies and are connected with the rhombic filler bodies, and the rhombic filler body comprises a pair of upper net plates and a pair of lower net plates. According to the invention, the shape change of the rhombic filler body is controlled, so that the loose state and the dense degree of the biofilm hanging silk are changed, the integrity of a biofilm is damaged, the internal pores of the biofilm are enlarged, the dense degree of the biofilm can be quantitatively and uniformly adjusted according to the actual situation, on the basis of not influencing the normal use of the biofilm, the internal porosity of the biofilm is improved, the adhesion capacity of the biofilm is reduced, and the separation of the aged biofilm is promoted so as to provide the combined filler which is easy to adjust, promotes demolding and has efficient degradation capacity for sewage treatment.

Description

technical field [0001] The invention relates to the field of composite packing, in particular to a composite packing for drawing and gathering and distributing sewage treatment. Background technique [0002] 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 the filler directly affects the efficiency of the biofilm water treatment process. [0003] Renewal and shedding process of biofilm: With the decomposition of organic matter, the thickness of biofi...
