黄浦江上游汇水区禽畜业污染及其防治对策

Animal Husbandry Pollution and its Harness Countermeasure in Upper Catchment of Huangpu River

为定量了解黄浦江上游汇水区禽畜业污染对黄浦江水网地区水环境的影响程度,对汇水区的禽畜业现状进行了调查,提出了各类禽畜的粪尿及其污染物的排泄系统,估算了禽畜粪尿总产生量及流失量。结果表明,汇水区禽畜粪尿流失量达91.3万t/a,由此产生的污染物COD_(Cr)为5.32万t/a,NH_3-N为0.58万t/a,分别是汇水区污染总负荷的38.3％和47.8％,成为黄浦江上游汇水区的主要污染源。对此,提出了防治禽畜业污染的几点对策与建议。

For quantification of the pollution effect of animal husbandry on the upper catchment of Huangpu River, an investigation have been conducted. Coefficient of various animal excreta was provided for estimating the total amount of excreta and discharge to the water course. The result showed that the total amount of animal excreta was 913 thousand t/a in upper catchment, among which CODcr was 53.2 thousand t/a and NH3-N 5.8 thousand t/a, or 38.3% and 47.8% of the total pollutant load respectively, so it may be a main pollution source in the upper catchment, then several countermeasures and recommendations for controlling pollution were also provided.
