Problems solved by technology

[0003] There are various types of fillers in the prior art, but in practical applications, most of the fillers are made of materials such as polypropylene, polyethylene, polyvinyl chloride or polyester, and the surface of the materials has poor hydrophilicity, resulting in biological fillers Poor surface wetting, low mass transfer performance, poor fluidization, slow growth and poor growth of microorganisms, resulting in slow biofilm formation, thin film formation, and ultimately poor treatment capacity for organic and nitro pollutants in water

Abstract

The invention relates to the technical field of sewage treatment, in particular to a biological filling material, which is prepared from the following ingredients of hydrophilic substrates, nutrients,adhesion filling materials, bonding agents and magnetic powder, wherein the hydrophilic substrates are obtained by mixing polyvinyl alcohol and polyacrylamide. The biological filling material has theadvantages that the specific surface area is large; the hydrophilic performance is good; the nutrition source is slowly released; the magnetic micro electrolysis environment can be made; the capturecapability on microbes in the sewage is high; the adhesion growth of colony is facilitated; good flocculated-adsorption and oxidization effects can be achieved on organic matters in the water; a biological film with compact structures can be further formed; the microbe growth can be promoted; the bioactivity can be activated; the operation starting time of the sewage treatment system is shortened;the filter pool volume and the occupied area can be reduced. The invention also provides a preparation method of the biological filling material and a sewage treatment system using the biological filling material.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biological filler and a preparation method of the biological filler. The invention also provides a sewage treatment system using the biological filler. Background technique [0002] At present, the known fillers in the sewage treatment process are mainly to increase the specific surface area of ​​the fillers and promote the formation of biofilms. The biological fillers used in water treatment can intercept the organic matter in the sewage, and more importantly, provide the "carrier" for the attachment of microorganisms and flora, so as to facilitate the formation of biofilms, use the colonies to decompose the pollutants in the water body, and then degrade the pollutants in the water body . As a microbial carrier, the filler is the core part of the biofilm process, and its performance directly affects and restricts the efficiency of sewage treatment. [0003] There ar...
