摘  要：
通过对粪污水进行分离、沉淀、曝气、生物滤池和添加微生物菌群有机物的降解对比试验,优选出了一套工艺流程,并在北京东广德猪场进行了工程实践。结果表明,优选出的以生物滤池为主的好氧生物处理工艺降解效率高、设备投资少、运行费用低且管理方便。高速生物滤池的降解率可达90%以上,整个污水处理系统有机物的降解率达到93%～97%。从系统运行水质监测结果来看,在保证粪污水全面实现达标排放和猪粪(渣)无害化处理的前提下,这种处理工艺将各个单一处理技术有机地结合起来,形成一种综合处理与利用的系统工程,达到经济、社会、生态效益的高度统一。

摘  要：
A new treatment system for disposal of swine wastewater is brought forward in accordance with the characteristics of swine manure- discharging way, the property of swine wastewater on intensive scaled swine farms. The results of our experiment showed: 1) According to the result of experiment set a sedimentation pond that adopt a method with nature proceeds to deposition to realize solid- liquid separation before treatment system on swine wastewater. 2) Foreign microorganism had no an obvious exaltation to removal rates of COD of wastewater, so we could share profits to use the microorganism in swine wastewater in treatment with swine wastewater. 3) Aeration could promote favorable oxygen microorganisms to decompose quickly organic compounds in swine wastewater, but the cost of running treatment system for swine wastewater was rather expensive, therefore we could supply super- speed biology filter pond with equipment for sending the breeze and add ample oxygen to fill the place of aeration device. 4) Establishment of an oxidized pond in the end of the system for treatment of swine wastewater could insure the swine wastewater reaching to state- standard and became “ zero of discharge” . The project practice of swine wastewater treatment in Beijing Dongguangde pig breeding farm showed that the optimal treatment system with the biological filter pond that good oxygen living creature was main saving the project investment, operating expenses, simplifying management and increasing efficiency of removal rates of COD. The removal rates of COD were more 90% in efficiency biology filter pond and the whole removal rates of COD were 93% ～ 97% of the new system. The results of removal rates of COD indicated that the new system form a comprehensive systemic engineering of excrement treatment and utilization, and reaching to a high unity of economic, social and ecological benefits, on condition of guaranteeing the prerequisite that the discharged swine wastewater reaches the state standard and swine manure was non- pollution treated.
