Problems solved by technology

Biofilm fillers can be roughly divided into two types: organic fillers and inorganic fillers. The former has poor biocompatibility, while the latter has poor specific surface area and compressive strength. Existing fillers cannot simultaneously achieve good biocompatibility, large specific surface area and High compressive strength

Abstract

The invention discloses biological membrane packing for treating livestock and poultry breeding wastewater and a preparation technology of the biological membrane packing. The density of the biological membrane packing is 0.96-0.98 g / cm<3>. The biological membrane packing is prepared from the following components in parts by weight: 58-62 parts of high density polyethylene, 10-18 parts of montmorillonite, 10-18 parts of powdered activated carbon, 11-20 parts of light calcium carbonate, 3-5 parts of shellac resin, 1.5-3 parts of gelatin, 0.5-1 part of cerous sulfate, and 0.5-0.8 part of fullerene. The biological membrane packing is suitable for treating the livestock and poultry breeding wastewater, and chemical oxygen demand (COD) concentration, ammonia nitrogen (NH3-N) concentration and total phosphorus (TP) concentration in the livestock and poultry breeding wastewater can be reduced effectively.

Description

technical field [0001] The invention relates to a biofilm filler, in particular to a biofilm filler for livestock and poultry breeding wastewater treatment and a preparation process thereof. It belongs to the technical field of sewage treatment. Background technique [0002] The chemical oxygen demand (COD) concentration of livestock and poultry wastewater is as high as 10000mg / L, ammonia nitrogen (NH 3 -N) concentration of 500~1300mg / L, total phosphorus (TP) concentration of 50~100mg / L, is a kind of organic wastewater rich in N and P, and is a serious pollution source in urban and rural areas, which is difficult and expensive to treat. The characteristics of livestock and poultry breeding wastewater are as follows: large discharge, large impact load; mixed solid and liquid, high concentration of organic matter, very difficult to treat; particularly high N and P nutrient content, low carbon-nitrogen ratio. [0003] At present, anaerobic digestion technology is widely used,...
