Problems solved by technology

[0008] In view of the fact that the existing livestock and poultry wastewater treatment cannot solve the problems of high metal content, nitrogen and phosphorus content, and heavy odor during the treatment process, the present invention provides a method for treating livestock and poultry wastewater using a biological composite filler. The biological composite filler used in the treatment process has a porosity and The packing has high mechanical strength. When treating livestock and poultry wastewater, it can absorb a large amount of macromolecular nutrients such as phytate phosphorus, residual veterinary drugs (antibiotics), urea, and suspended solids, as well as metal elements such as copper, iron, and zinc, and biofilms. Strong performance, it also has disinfection effect while adsorbing, can kill pathogens in wastewater, and effectively solves the problem of difficult livestock wastewater treatment

Abstract

The invention discloses a method for processing livestock waste water through bio-compound fillers and belongs to the field of livestock farming waste water treatment. The method comprises the steps of (a) pouring the bio-compound fillers into livestock waste water to be processed for soaking for 3-10 hours, wherein the volume ratio of the bio-compound fillers and the livestock waste water is 1:(10-20); (b) taking out the soaked bio-compound fillers in the step (a), stacking the soaked bio-compound fillers into a conical shape, covering the surface of the soaked bio-compound fillers with a layer of wheat straw or maize straw for high-temperature compost. According to the method for processing the livestock waste water through the bio-compound fillers, the bio-compound fillers utilized during the treatment process are high in porosity and mechanical strength, and when being utilized to process the waste water, can absorb large amounts of macromolecular nutrient elements such as phytate phosphorus, veterinary drug residue, urea and suspends solid as well as metal elements such as copper, iron and zinc inside the waste water and kill pathogens inside the waste water, so that the problem of difficulty in livestock waste water treatment can be effectively solved.

Description

technical field [0001] The invention belongs to the field of livestock and poultry breeding wastewater treatment; in particular, it relates to a method for treating livestock and poultry wastewater by using biological composite fillers, more specifically, it relates to a method for treating livestock and poultry breeding wastewater with high ammonia nitrogen load, difficult to reach the standard, and residual There are many drugs and high treatment costs, and a wastewater treatment method that can be treated to make it reach the standard is provided. Background technique [0002] In recent years, with the development of intensive aquaculture and large-scale aquaculture in our country, a large number of farms have appeared in rural areas. The wastewater discharged by these farms is large and concentrated every day, and the wastewater contains a large amount of pollutants, such as heavy metals, residual Veterinary drugs and a large number of pathogens have caused new environme...
