摘要
在太湖梅梁湾强化净化示范区内布设了渔网围栏工程,研究了围栏介质对水体的净化效果.研究结果表明,围栏介质能显著提高水体透明度,在1月份的试验中水体透明度提高了20cm,在6月份的试验中水体透明度提高了30cm;2次试验中的水体叶绿素a、总磷(TP)和总氮(TN)的削减率分别为62.5%、22.5%、37.8%和43.8%、30.9%、60.5%;据此估算,示范工程区的渔网围栏每年大约能去除TP和TN的量分别为40.5,963.6kg.
The fishing net paling engineering was set up in the strengthened and purified exemplary area of Mcihang Bay; and the purifying effect of net paling medium on waters was studied. Net paling medium could enhance obviously the water transparency enhancing 20cm in January test; and 30cm in June test. The reducing rate of chlorophyll a, TP and TN were 62.5%, 22.5%, 37.g% respectively in first test and 43.8%, 30.9%, 60.5% respectively in second test. Based on this, it was estimated that the fishing net paling in the exemplary area could remove about TP 40.5kg and TN 963.6kg per year.
