摘　　要：猪场污染物特性参数是衡量粪污无害化和资源化利用的重要依据。为深入掌握江西规模猪场粪污特别是污水多级处理后的污染物特性参数变化特点,选择采用“USR+A/O+MBR”工艺污水处理模式的江西新建区某规模养猪场,对其养殖过程中排出的粪便和污水处理各环节污染物特性参数进行周年季节性监测。结果表明:鲜粪经堆沤发酵后OM、NH 3-N、TN、TP特性参数值分别为50.84%、0.41%、2.47%、5.94%,其中的OM和TP含量增加,NH 3-N、TN含量减少;污水最后出水中COD、NH 3-N、TN、TP特性参数值分别为386.06 mg/L、70.89 mg/L、493.53 mg/L、7.61 mg/L,污染物总去除率分别达到95.40%、72.73%、91.41%、95.89%。说明规模猪场污水采用“USR+A/O+MBR”组合工艺处理模式,污染物去除效果好,出水水质达到畜禽养殖业污染物排放标准要求。The pollutant characteristic parameters of a pig farm are the important basis for the evaluation of harmlessness and resource utilization of pig manure.In order to understand the variation of pollutant characteristic parameters after multistage treatment of manure,especially for sewage,in Jiangxi large-scale pig farms,a large-scale pig farm with USR+A/O+MBR wastewater treatment model in Jiangxi was selected to conduct annually seasonal monitoring on pollutant characteristics in each stage.The results showed that the parameters of Manure OM,NH 3-N,TN and TP were 50.84%,0.41%,2.47%and 5.94%,respectively,and the contents of OM and TP increased,but the contents of NH 3-N and TN decreased.The characteristic parameters of COD,NH 3-N,TN and TP in the final effluent were 386.06 mg/L,70.89 mg/L,493.53 mg/L and 7.61mg/L respectively,the total removal rates of pollutants were 95.40%,72.73%,91.41%and 95.89%,respectively.The results indicate that the combined processing mode of“USR+A/O+MBR”can remove the pollutant well,and the effluent water quality meets the requirements of pollutant discharge standards of livestock and poultry industry.
