- 摘要：通过构建水生动物-人工介质新型生态系统来研究太湖水源地水质改善效果.中试试验结果表明,对比3d和7d的水力停留时间(HRT),当HRT=7d,系统对TN、NO2--N、NO3--N、TP、PO4--P的平均去除率可分别达到79.00%、63.46%、14.57%、67.43%、35.81%;对比空白池,TN、NO2--N、NO
- Abstract：Pilot tests were made on the improvement of source water quality in Taihu Lake through the construction of an aquatic and artificial media ecological system. A 7 day HRTgives the highest removal rate and capacity and benefit. Under these conditions, the average removal rates were 79.00% TN, 63.46% nitrate nitrogen, 14.57%nitrite nitrogen, 67.43% TP, and 35.81% phosphate phosphorus. In contrast, in the deposition pool, the average removal rates only reached 9.67% TN, 7.09%nitrate nitrogen, 1.30% nitrite nitrogen, 9.92% TP, and 7.04% phosphate phosphorus. Through coordination of aquatic absorption and micro-degradation on artificial media, significant amounts of nitrogen and phosphorus pollutants were removed. It is evident that the source water quality in Taihu Lake can be significantly improved by use of the aquatic and artificial media ecological system.
