摘　　要：本文以规模化养猪场的污水处理工程实例分析了各阶段的处理效果,结果认为,在改进规模化养猪场传统污水处理方案时,应用固液分离机进行前处理对去除SS,COD,BOD和NH3等效果好,去除率分别为75.7%,62.4%,59.9%和18.3%,且投资省、回收快,不增加企业的运行费用负担。This article briefly introduced the present state of development of large scale pig farm and the wastewater discharge in Fujian province. On the basis of a case study of wastewater treatment on a Large Scale Pig Farm, it was found that solid-liquid separators, as prctreatment, could help the removal of SS, COD, BOD and NH3, which could reach the removal rate of 75.7%, 62.4%, 59.9% and 18.3% respectively,thus greatly improving efficiency of wastewater treatment. It also has the advantage of less cost, and no financial burden of transportation.
