摘要 选取抚顺市典型地区30户农户作为研究对象，运用实地抽样调查、现场监测及SPSS软件数据分析等方法对农户生活污水各类污染物产污系数进行研究。结果表明，30户监测农户的农村生活污水人均日排量和COD、BOD5、NH3-N、TN、TP、动植物油浓度的平均水平分别为30.03 L/（人·d）、784.08 mg/L、388.74 mg/L、3.27 mg/L、18.31 mg/L、2.66 mg/L、7.36 mg/L;农村生活污水中COD与BOD5、NH3-N、TN、TP、动植物油之间存在显著正相关，人均日排污水量与COD、BOD5、NH3-N、TN、TP、动植物油之间不存在显著相关关系;收入水平对农户生活污水中COD和BOD5产污系数无显著影响，但对人均日排污水量和NH3-N、TN、TP、动植物油产污系数影响极显著。

Abstract 30 households in typical areas of Fushun City were selected as the research objects，and the product-pollution coefficients of household sewage were studied by means of field sampling survey，field monitoring and SPSS software data analysis.The results showed that the average daily discharge of rural domestic sewage per capita and the average levels of COD，BOD5，NH3-N，TN，TP and animal and vegetable oil concentrations of 30 monitored farmers were 30.03 L/（person·d），784.08 mg/L，and 388.74 mg/ L，3.27 mg/L，18.31 mg/L，2.66 mg/L，7.36 mg/L，respectively.There was a significant positive correlation between COD，BOD5，NH3-N，TN，TP and animal and plant oil in rural domestic sewage，while there was no significant correlation between the average daily discharge of rural domestic sewage per capita and COD，BOD5，NH3-N，TN，TP and animal and plant oil.The income level had no significant effect on the COD and BOD5 pollution production coefficients in the total domestic sewage of farmers，but it had a very significant effect on the per capita daily sewage discharge and the NH3-N，TN，TP，animal and vegetable oil pollution production coefficients.

農村生活污水与农村饮用水源安全及环境质量密切相关，污水随意排放已经严重污染农村地区环境及水源，是我国近3亿农村人口饮用水不达标的原因之一，极易导致某些流行性疾病的发生与传播，农村生活污水面源污染是导致江河湖泊富营养化和水环境恶化的主要原因[1]。

农村居民生活排水污染物产生量与气候、水资源、生活水平等密切相关，为了建立合理的农村生活源水污染物产生系数，该研究综合考虑自然地理分区、水系分区，选取抚顺市代表辽宁东部山区现状。目前，针对农村生活污染源污染的研究相对较少，有关抚顺市农村生活污水产污系数的研究鲜见报道，因此，该研究选取6个典型行政村不同经济收入水平的30户典型农户为监测对象，开展抚顺市农村生活源水污染物产污系数测算的研究，确定抚顺市农村生活源水污染物产污系数，从而为抚顺市农村生活污染源控制提供理论依据。……
