英语翻译
The most effective approach for cleaning up contaminated surface water is to prevent further discharges from contaminated sources and enable natural biological,chemical,and physical processes to break down the existing contamination.In some surface water bodies where natural processes are not enough to break down the contaminants,other cleanup approaches such as mixing and aeration may be required to further promote natural cleanup.A significant source of surface water contamination may be contaminated sediments.Contaminated sediments generally contain persistent contaminants and are difficult to clean up.Three main approaches to cleaning up contaminated sediments are:1) remove them by dredging; 2) place a cover over them to prevent contact with the surface water; or 3) allow natural processes to cover them or break them down over time.For contamination that does not mix with surface water and floats on the surface,such as that encountered during an oil spill,contamination can be removed by skimming it from the surface using a "boom."

整治地表污水的最有效方式是防止进一步污水排放,并且使自然生物,化学和物理作用降解现有污染.然而一些地表水体不具备充分恢复能力,所以需要一些其他的方式来帮助自然清理,如搅拌和通风.地表水污染的一个重要原因可能是沉积物污染.被污染的沉积物一般都有持久污染物,这很难清除.
治理沉积物污染的三个主要方式是：
1,挖出沉积物
2,覆盖沉积物表层,避免其于地表水接触
3,随着时间,通过自然过程覆盖或降解
不与地表水混合和浮在水面的污染,像石油泄漏,这种污染可以用水栅从水面刮去.（这可是我一句句做的哦!可不是翻译软件哦!

没分还那么多，你好意思。

清理被污染的地表水最有效的方法是防止进一步污染排放源，使自然生物，化学和物理过程，以打破现有的污染。在一些地方地表水体的自然过程，不足以打破污染物，如混合和曝气其他清理方法可能会被要求进一步促进自然清除。地表水受到污染的重要来源，可能被污染的沉积物。受污染的沉积物普遍含有持久性污染物，难以清理。三项主要方法清理受污染的沉积物是：1）消除疏浚他们; 2）地方对他们的幌子，以防止地表水的接触;或3）允...
