The Guanzhong Region Rural Livestock And Poultry Breeding Pollution Control Technology Integration Research

With the rapid development of the rural livestock industry, livestock pollution is a growing problem, and has become a major source of environmental pollution in rural areas. Our country’s existing livestock and poultry pollution treatment technology policy and the standard is mainly aimed at large scale farms and culture zones, for smaller rural scattered and concentration of livestock and poultry fanning areas, mature technology, economic and reasonable pollution treatment technology is still not perfected.In ecology theory, the theory of circular economy, sustainable development of the theory as guides, on the basis of analysis and summarized domestic and international livestock pollution control technology, through the investigation and study in Guanzhong area of the livestock and poultry and pollution situation, integrative livestock and poultry pollutants processing technology, put forward Guanzhong rural area the appropriate integrated treatment technology for livestock and poultry pollutants.The main findings are:(1) Livestock and poultry pollutants processing of scattered household should use "Anaerobic fermentation+biogas treatment process", combined with people excrement and urine build biomass pool to treatment pollutants, can also use "natural compost process"(2) Livestock and poultry pollutants processing of large breeding should use "Solid-liquid separation+compost+oxidation ponds process","Anaerobic fermentation+biogas treatment process"(3) Livestock and poultry pollutants processing of breeding region should use "Fermentation bed breeding technology","Anaerobic fermentation+biogas treatment process". build with village-level comprehensive utilization network of gas pipeline.(4) Livestock and poultry pollutants processing of scale livestock and poultry farms primarily in order to realize pollutants harmless treatment and recycle utilization, according to different conditions and requirements, should use "Solid-liquid separation+solid compost+liquid (anaerobic treatment+aerobic treatment) process","Hybrid anaerobic fermentation+methane project technology"...
