施用木薯酒精好氧发酵液对香蕉园土壤及水质的安全性评价

Safety evaluation on soil and water in banana plantation irrigated with aerobic fermentation liquid of cassava alcohol

为了解木薯酒精好氧发酵液（COD为200～900 mg/L）对香蕉园土壤和水质的影响,采用单因子污染指数法和内梅罗综合污染指数法对园区土壤的重金属含量进行评价,并评价园区内饮用井水的水质状况.结果表明,施用好氧发酵液区域的香蕉园土壤综合污染指数在0.47～0.72之间,属清洁或尚清洁等级,土壤未受到污染;并且园区中的饮用井水符合生活饮用水卫生标准,没有受到污染.

In order to understand the effects of aerobic fermentation liquid of cassava alcohol （AFLCA, COD was 200- 900 rag/L） on soil and drinking well water （DWW） in banana plantation, the quality of DWW and the content of heavy metal （Hg, Cd, Pb, As and Cr） in soil were analyzed and evaluated by single factor index and Nemerow multi-factor index method. The results showed that, the comprehensive pollution index of heavy metal in soil was 0.47-0.72, reached cleaning or slight cleaning grade. The quality of DWW was up to standard of water conventional quality index. The soil and DWW in banana plantation irrigated with the AFLCA was not polluted.
