集约化奶牛场污水磷污染指数的测定

Determination of Sewage Phosphorus Pollution Indexes in Intensive Cow Farm in Four Seasons

采集集约化奶牛场四季节污水样进行磷含量测定,计算出奶牛场污水磷污染指数,并对四季节间磷污染指数差异进行比较分析。结果显示,四季节奶牛场污水磷含量春季最高,冬季最低,污水磷污染指数呈现与其相同的变化规律。

Through the determination of the phosphorus contents of sewage samples from the intensive cow farms,the sewage phosphorus pollution indexes of four seasons were calculated and their differences were analyzed.The results showed that the sewage phosphorus content was the highest in spring and the lowest in winter,the same was the sewage phosphorus pollution index.
