Problems solved by technology

[0002] Typical fillers on the existing market, such as Longtai Environmental Protection (Filler) Co., Ltd., which specializes in the production of various environmentally friendly water treatment fillers, are made of PE, which has a high bulk density and relatively poor suitability for the growth of biofilms.
However, the existing disclosed technology fails to comprehensively consider the performance of fillers: including hydrophilicity (suitable for the growth of biofilms), suitable for the growth of aerobic, facultative and anaerobic bacteria, the specific gravity of fillers, and the materials used Cost and durability of use, etc.

Abstract

The invention discloses a biosorption filler for treating industrial wastewater. The biosorption filler comprises the following substances (by weight): 14-20 parts of PA, 3-14 parts of PB, 4-6 parts of sodium hydroxide, 1-8 parts of calcium hydrate, 11-21 parts of ion exchange resin, 16-27 parts of PE, 10-26 parts of PLA, 1-3 parts of a nanoscale granular inorganic material, 2-6 parts of calcium carbonate, 1-8 parts of mica powder, 2-4 parts of acrylic fibers, 1-7 parts of polypropylene ester fiber, 3-8 parts of hollow glass beads, 3-7 parts of gypsum powder, 8-15 parts of iron oxide and 4-11 parts of a phosphite anti-oxidant. The method of the invention is simple, and the product is easy to produce and manufacture. With die treatment, the product has rough surface and is microporous. Thus, specific surface area of the product is large, and surface wettability of the filler can be improved. The product is more beneficial to biofilm formation of microbes.

Description

technical field [0001] The invention belongs to the field of industrial wastewater treatment, in particular to a biological adsorption filler for industrial wastewater treatment. Background technique [0002] Typical fillers on the existing market, such as Longtai Environmental Protection (Filler) Co., Ltd., which specializes in producing various environmental protection water treatment fillers, are made of PE, which has a high bulk density and relatively poor suitability for the growth of biofilms. However, the existing disclosed technology fails to comprehensively consider the performance of fillers: including hydrophilicity (suitable for the growth of biofilms), suitable for the growth of aerobic, facultative and anaerobic bacteria, the specific gravity of fillers, and the materials used Cost and durability of use, etc. Chinese patent CN1740102 discloses an integrated flocculation biological fluidized bed sewage treatment process, for the purpose of integrating the first...
