餐厨垃圾废水与垃圾渗沥液混合生化预处理技术研究

摘要

将餐厨垃圾废水与垃圾渗沥液按一定比例混合后,利用硝化-反硝化处理工艺对其进行预处理.结果表明,出水CODCr去除率达到85％,氨氮去除率达到58％,总磷去除率为74％,电导率降低率达到63％.采用生化工艺作为餐厨垃圾废水与渗沥液混合液的预处理工艺是可行的.%Wastewater from food waste and waste leachate were mixed by a certain percentage for pretreatment by using nitrification-denitrification process. The result showed that the removal rate of CODCr in the effluent reached 85%, the removal rate of ammonia nitrogen reached 58% , the removal rate of total phosphorus was 74% , the reduction rate of conductivity reached 63%. It is feasible that the mixture of wastewater from food waste and waste leachate is pretreated by using biochemical process.
