Biological carrier for efficiently treating industrial wastewater

Abstract

The invention discloses a biological carrier for efficiently treating industrial wastewater, which is characterized by comprising the following components in parts by weight: 34-45 parts of PA (polyamide), 10-19 parts of PB (polybutadiene), 5-9 parts of nitric acid, 120-150 parts of elastic emulsion, 2-4 parts of zinc oxide, 5-15 parts of flame retardant, 30-60 parts of organic silicon modified epoxy resin, 20-50 parts of mixed solvent, 0.3-0.5 part of thickener, 0.1-0.3 part of wetting agent, 0.3-0.5 part of dispersant, 0.2-0.5 part of antifreezing agent and 3-9 parts of antiaging agent. The method is simple and easy for production and manufacturing; and by adding the mold treatment, the product surface is coarse and microporous, and thus, the product has large specific area, can improve the surface wettability of the filler, is more beneficial to biofilm formation, and can greatly enhance the biofilm formation speed and fastness in the water treatment system.

Description

technical field [0001] The invention relates to a biological carrier for efficiently treating industrial waste water. Background technique [0002] Typical fillers on the existing market, such as Longtai Environmental Protection (Filler) Co., Ltd., which specializes in producing 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. Chinese patent CN1740102 discloses an integrated flocculation biological fluidized bed sewage treatment process, for the purpose of integrating the first-level enhanced technology and biological fluidized bed techn...
