呼和浩特市奶牛粪便产生量估算及耕地负荷

The estimation of Dairy manure yield and farmland load in Hohhot

通过对奶牛粪便年排放量的估算方法和奶牛粪便排泄参数的确定,估算了呼和浩特市奶牛养殖业粪便产生量并对由此产生的土壤负荷进行了分析。结果表明,2009年呼和浩特地区奶牛养殖业共产生7966979.1 t粪便,是当年工业产生固体废物的1.2倍;奶牛粪便及其中的砷、汞、镉、铜平均耕地负荷分别为17.97t/hm2、75.6g/hm2、1.4g/hm2、30.9g/hm2和136.6g/hm2,部分地区的养殖业已经对当地环境构成了污染。

Through the determination of the estimation method of Dairy manure emissions and Cow feces excretion parameters , We have estimated Dairy cattle manure production in Hohhot and analysis The resulting soil load. The results show that Milk cow aquaculture in Hohhot in 2009 produced 7966979.1 t . as 1.2 times of the industrial solid waste; Cow manure and the average cultivated land load of arsenic, mercury, cadmium, copper are 17.97t/hm2, 75.6g/hm2, 1.4g/hm2, 30.9g/hm2and 136.6g/hm2,Part of the aquaculture of the area have on the local environment form pollution.
