养殖场粪污“三分离一净化”综合处理技术集成研究

摘要

Integrated treatment technology on livestock and poultry farm fecal sewage was studied with the existing mature rain sewage diver-sion process, drying nightsoil process, squeezing dewatering process and wastewater deep purification. Engineering model was designed and demonstration project was constructed. The practice indicated that it achieved remarkable results on comprehensive treatment and utilization of scale livestock and poultry farm waste, with the removal rate of COD and ammonia nitrogen over 96%, worth of expansion in suitable area with reliable operation and convenient management.%通过对现有的比较成熟的雨污分流工艺、干清粪工艺、挤压脱水工艺以及废水深度净化处理等工艺技术集成，设计养殖场粪污“三分离一净化”综合处理工程模式，并选择养殖场实施示范工程建设。实践表明，本研究在解决规模畜禽养殖场粪污综合处理与利用方面成效显著，养殖污水COD和氨氮去除率均达96%以上，且运行可靠、管理方便，适宜有条件的地区推广运行。
