人类赖以生存的最基本的物质之一首当为水资源。在我国经济发展迅速的今天,随之而来的是环境污染相应严重,尤其是饮用水污染尤为突出,目前百姓日常用水主要是自来水,但自来水的水质尚有待改进,其症结主要体现在以下三个方面:1、水源污染:国家环境部门统计,我国80%的河流受到不同程度的污染;在我国七大水系中,不适合做饮用水源的河段已接近40%,城市水域中78%的河段不适合作饮用水源;约50%的城市地下水受到污染。随着现代工业的飞速发展,水体正受到工业废水、汽车尾气、农药、石油化工等中的铅、苯、酚等有机物的化学污染
One of the most basic things human beings depend on is water resources. In our country’s rapid economic development, the ensuing serious environmental pollution, especially drinking water pollution is particularly prominent, the current daily water use is mainly tap water, but tap water quality has yet to be improved, the crux of the problem is mainly reflected in the following three Aspects: 1.
