Integral ecological breeding house capable of effectively utilizing breeding waste resource

Abstract

The invention belongs to the technical field of comprehensive utilization of waste and particularly discloses an integral ecological breeding house capable of effectively utilizing a breeding waste resource. The breeding house includes a breeding house body, the breeding house body comprises wall bodies and a ceiling; the breeding house body is internally provided with a culture area, a breeding waste solid-liquid separation area and a urine utilization area; a semi-in-situ compost area is arranged outside the breeding house body, the breeding waste solid-liquid separation area is arranged between the breeding area and the urine utilization area, and the semi-in-situ compost area is arranged on one side of the urine utilization area. The breeding house is used for disposing breeding wastegenerated by fragmentary breeding of farmers, the resource utilization rate of the breeding waste can be greatly increased, and discharged breeding pollution loads are reduced. Through the biologicalbreeding house, efficient dry-wet separation of the breeding waste on site, semi-in-situ aerobic composting of solid feces, fermentation of urine for preparation of nutrient soil and other functions are integrated into a whole part, feces and urine are not accumulated in the breeding house, the breeding waste is effectively converted into a resource, and the breeding house has the advantages of being safe and sanitary, less in emission of pollutants, easy to operate and maintain, high in resource utilization and the like.

Description

technical field [0001] The invention belongs to the technical field of waste comprehensive utilization, and in particular relates to an integrated ecological pen for effective utilization of breeding waste resources. Background technique [0002] my country is a large country of livestock and poultry breeding. Due to the limitation of economic conditions and the influence of breeding habits, the breeding methods of family sporadic stables widely exist in the vast rural areas. It is difficult to effectively collect and treat aquaculture pollutants in sporadic stables. Aquaculture sewage is often mixed with rural domestic sewage, which has a great impact on the external environment and is an important non-point source of pollution in rural areas. Taking dairy farming as an example, usually one household raises 1-4 cows. Through investigation, each cow produces about 20kg / d of feces and about 10kg / d of urine. COD in 1kg of fresh feces cr The amount produced is about 30g, the...

AI Technical Summary

Problems solved by technology

However, household biogas digesters have a low gas production rate and troublesome cleaning and maintenance, and many of them have been abandoned by farmers; household manure ponds, livestock and poultry manure collection stations, etc. have a limited collection rate of livestock and poultry manure, and it is difficult to collect livestock and poultry urine separately. Untreated wastewater mixed with rural domestic sewage enters rural domestic sewage treatment stations

Due to the high concentration of organic matter, nitrogen, phosphorus and other pollutants in the aquaculture wastewater, as well as the high content of mucus and suspended solids, it often causes the treatment load of rural domestic sewage treatment stations to be overloaded and blocked, which affects the normal operation of sewage treatment stations.
