上海市郊原有水厂400余座,供水人口300多万。但由于水源恶化,有些另觅水源,或引水、或迁厂;有些勉强维持,水质无保证;有些则想接通市属大水厂的管网而关闭原水厂。星罗棋布的市郊水厂说明历史上郊区水质的优良,是农村改水工作的硕果。面对水环境的逐年恶化,这些水厂能否存在下去是衡量我们能否治理好水污染的明显标志。 There are more than 400 existing water plants in the suburbs of Shanghai, and the water supply population is more than 3 million. However, due to the deterioration of water resources, some other water sources, or water diversion, or relocation; some barely maintained, the water quality is not guaranteed; some want to connect the municipal water plant pipe network and close the original water plant. The suburban water plants scattered across the country illustrate the suburb’s excellent water quality, which is a fruit of rural water improvement work. Faced with the deterioration of the water environment year after year, the existence of these water plants is a clear indicator of whether we can manage water pollution.
