改善湖泊水环境的调水与生物修复结合途径探索

分析了生物修复和引清调水措施在改善湖泊水环境的优点和不足,指出单独采用其中一种方法,在解决湖泊污染问题上都存在一定的局限性,而将二者结合起来既能充分发挥各自的优点,又能加快湖泊生态恢复的步伐.在此基础上,对二者结合途径进行探索.以汉阳四湖为例,引清调水与生物修复可以通过3种主要途径结合: 短期引清调水与长期生物修复相结合,局部生物修复与大区域调水置换结合,水力调度调控与湖泊生物恢复结合.

Exploring possibility to regain polluted-lake water quality by means of bioremediation and water diversion

This paper makes a detailed discussion on the advantages and disadvantages of bioremediation and water division in trying to regain the quality of the polluted lake water. The author's conclusion is that it is beyond expectation neither to rely on bioremediation nor on water division separately and singly. Rather, a comprehensive set of measures are to be adopted to solve the problem of the pollution. The so-called comprehensive or combined set of measures means to bring about the full advantage of these two ways of measures plus to the careful measures for lake environment protection. At this crucial juncture, the authors of this paper explored the realistic approaches to the final solution. Taking the water quality control project of the four lakes of Hanyang as example, the authors suggest that there are three approaches to the combined use of bioremediation and water division. There are combination of short-term water division and long-term bioremediation, combination of partial bioremediation and large-scale water replacement, as well as the combination of hydrodynamic management and biorestoration.
