Research Aerobic Composting Of Livestock And Poultry Manure

As China's reform and opening up and economic development, livestock and poultry breeding industry has seen rapid development. According to the National Environmental Protection Ministry survey in 1999, the generation of pollutants in livestock manure, only one had already far exceeded the COD of industrial and domestic wastewater COD of pollutants and, therefore, livestock farming has become China's largest polluting industries. Strengthening of livestock and poultry breeding industry, pollution prevention, environmental protection, rural China has become the present stage the most important task is a pressing need urgent task.This study was treatment of livestock waste pollution and the status of the investigation, analysis, selection of livestock and poultry manure composting technology line. A comprehensive and systematic study of the aerobic composting process, a detailed analysis and elaboration of the composting process to a simple and effective method of determination of oxygen consumption rate, calculate the exact amount of gas, in the best biological response under the control of the aerobic composting conditions, process. Thereby not only improved the aerobic composting theory, for the livestock and poultry manure composting industrial production has played a more direct, cost-effective guide.
