Biofilm filler for livestock and poultry breeding wastewater treatment and its preparation process

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,...
