摘要
采用原子吸收分光光度法测定废水中重金属元素的含量并进行污染评价。结果表明:仁怀市酒厂废水呈强酸性,废水中重金属铜、铅、镉、铬、锰含量均很低,其单项污染指数远低于0.700,完全能达到国家综合污水排放一级标准。小作坊底锅水和窖底水中锌元素含量偏高,其单项污染指数大于1.000,综合污染指数大于0.700,但低于国家综合污水排放二级标准,根据单项及综合污染指数计算分析,属轻度污染等级。其他种类的废水完全达到国家综合污水排放一级标准。
The content of heavy metals element in distillery waste water were determined by atomic absorption spectrophotometry and the pollution evaluation was taken. The results showed that the distillery wastewater was strong acid, the content of each one of copper, lead, cadmium, chromium and manganese was low, which the single pollution index was far less than 0.700, which could meet with a class standard of national waste syntheti- cal discharge. The content of zinc in pot-bottom water from small workshop and pit-bottom water was slightly high, and the comprehensive pollution indexes of them were over 0.700 and the single pollution index were more than 1.000, which were far less than the national second standard of wastewater discharge Based on the calculation and analysis of the single and comprehensive pollution indexes,which were in light pollution level. Other kinds of wastewater, which could attain a class standard of national waste synthetical discharge.
