拜托翻译下!机译则不给分
Several landmark studies that have provided a sound technical basis for the safe use of reclaimed wastewater for various beneficial uses were reviewed in this paper. Emphasis, however, was on direct nonpotable reuse applications. The era of wide-spread wastewater reclamation, recycling and reuse started in the 1960s with appropriate wastewater treatment and reuse regulations. The recent trends in wastewater reuse are for direct reuse in urban environments such as landscape irrigation, toilet flushing, industrial uses, recreational and ornamental impoundments. With tertiary and advanced wastewater treatment, groundwater recharge has been implemented. Indirect or direct potable water reuse has been intensively studied and a few projects have been implemented or are currently under development.

Answer 1

一些具有里程碑意义的研究,提供了坚实的技术基础,也为安全使用填废水利用各种有利本文进行了审查.然而,重点是对直接nonpotable重新申请.时代广布填海废水、回收与再利用始于60年代,并提供适当的废水处理回收法规.最近的趋势是直接回收废水再利用,如城市环境景观灌溉、冲水厕所、工业用地、娱乐、观赏impoundments.大专及先进的废水处理,地下水已经执行.直接或间接的饮用水循环是深入研究和一些项目已经落实或正在研制.
