养猪废水氮磷污染及其深度脱氮除磷技术探讨

Approaches on Nitrogen Phosphorus Pollution of Pig Raising Wastewater and the Technique of Depth Denitrogen & Phosphorus Removal

通过对规模化养猪场废水氮磷污染监测 ,揭示氮磷污染现状 ;研究生物脱氮除磷的机理和途径 ,指出传统 A/ O工艺脱氮除磷局限性 ;探讨养猪业废水在沼气厌氧发酵基础上进行深度脱氮除磷的水生生物氧化塘工艺的可行性。

Through monitoring nitrogen phosphorus pollution of large-scale pig raising wastewater,the paper indicates the current status of nitrogen phosphorus pollution,and studies the mechanism and pathway of biological denitrogen & phosphorus removal,and then indicates the limitation of traditional A/O process on denitrogen & phosphorus removal,discusses the feasibility of depth denitrogen & phosphorus removal with the hydrobiology oxidation pool process based on the methane anaerobic zymolysis.;
