问题                             水污染的防治
    水污染的防治并不简单,而且大规模的水污染治理往往代价高昂。所有的现代都市都需要高效、安全的污水处理系统,但这些污水处理系统自身的运转也需要消耗水量。现在,关注的热点都集在废水的重复利用方面,根据废水的净化程度,有些净化过的水可以正常使用。

选项

答案     There is no easy answer to prevention nor are there any cheap processes for the large scale treatment of water supplies. All modern cities demand effective, and safe, sewage systems which by their very nature, require a large percentage of available water. A lot of attention is now being directed toward the recycling of waste water. Depending on its level of purification, some of this water can be suitable for normal consumption.
