【摘要】：通过对河南省不同规模生猪养殖户(企业)的典型案例调研,提炼了不同养殖规模下,生猪粪便处理的主要模式,分规模估算了污染系数和排污量占比,并对比分析了不同养殖规模粪便处理的成本收益现状.研究发现:不同养殖规模在粪便处理方式的选择上存在较大差异,成本收益和监管力度是决定养殖户采取不同粪便处理方式的关键因素;我国生猪养殖污染排放的压力较为严重,污染治理设备投资资金压力大、缺乏配套的种植用地消化畜禽粪便、粪便循环利用的经济效益较低、有机肥市场监管不完善等问题是制约养殖户减少粪便污染的重要因素.在此基础上,本文提出了促进生猪粪便利用、减少环境污染排放的政策建议.
[Abstract]:Based on the investigation of typical cases of pig farmers (enterprises) of different scales in Henan Province, the main models of pig feces treatment under different scale were refined, and the pollution coefficient and the proportion of sewage discharge were estimated in different scales.The cost-benefit status of fecal disposal in different scale was compared and analyzed.It was found that there were great differences in the selection of fecal disposal methods in different breeding scale, and the cost, income and supervision were the key factors to determine the different faeces treatment methods of breeders.The pressure of pollution discharge from live pig breeding in China is more serious, the investment and capital pressure of pollution control equipment is great, the waste of livestock and poultry is digested by the lack of supporting planting land, and the economic benefit of recycling feces is low.Imperfect supervision of organic fertilizer market is an important factor restricting farmers to reduce fecal pollution.On this basis, the paper puts forward some policy suggestions to promote the utilization of pig manure and reduce the discharge of environmental pollution.
