| 摘 要： | 对灵武规模化养殖场开展粪便废水污染特征研究,监测结果表明,灵武养殖场水污染物中的总氮、总磷、化学需氧量(COD)和5日生化需氧量(BOD5)均超过国家相关排放浓度标准,排放量均未超标,但污染负荷较高;总氮年排放总量达到4.86 t,COD达到19.92 t,总磷0.17 t,各项指标浓度冬季明显高于夏季,但污染负荷差异不大;养殖业水污染物对试验监测区下游干支沟排水的水质影响较大,排水中的总氮、总磷和COD均有不同程度超标,且冬春季>夏秋季。 |

| Abstract: | Studies on characteristic of wastewater pollution were carried out in large scale farm of Lingwu city.The monitoring results showed: The concentration of total nitrogen,total phosphorus and COD and BOD5 all exceeded the standard of national emission,while the amount for discharge were in the range of national standard with high pollution loading;The total amount of annual emission reached to 4.86 ton,COD reached to 19.92 ton and total phosphorus reached to 0.17 ton.Every concentration of pollutant index was higher in summer than in winter with no difference of pollution loading;Wastewater pollutant of breeding industry effected heavily on water quality of downstream branch ditches’ drainage of monitoring zone for experiment.The total nitrogen,total phosphorus and COD for discharge averagely exceeded to the standard with different degree,which was higher in Winter-Spring than in Summer-Autumn. |
