摘要
对浙江安吉县大溪景区的水环境进行了调查,对景区及其周边水体的温度、pH、高锰酸盐指数、DO、NH3-N、动植物油、总磷、总氮以及排污口COD进行监测,结果表明,大溪溪在未接纳餐饮废水之前就已受到轻微磷污染,其最下游水库已富营养化。大溪溪水质总体基本良好,除总氮指标外,经自身净化后仍能保持在Ⅰ～Ⅱ类水标准,属微污染水,不加控制有恶化趋势。
The water quality was investigated with a view to assessing the aqueous environment of a tourist spot located in Daxi, Anji County of Zhejiang Province. The status quo was probed emphatically by monitoring several factors including temperature, pH, permanganate index, dissolved oxygen（DO）, ammonia nitrogen（NH3-N）, animal and plant oil, total phosphor（TP）, total nitrogen（TN） and COD of aqueous environment in and around the tourist spot area. The results showed that Daxi had been polluted by phosphorus before taking in the wastewater, and the backward position reservoir was eutrophic. The water quality of the whole Daxi was basically good and after selfpurification it would reach Ⅰ to Ⅱ grade standard. However, it was still micro-polluted water and the deterioration of aqueous environment would be much more serious without taking effective measures.
