Abstract

本发明公开了一种用于被三氧化二砷污染水源后的应急处置方法，旨在提供一种安全高效的应急处置方法，它包括在受污染水体中投加大量的石灰中和沉淀，在事故点上游筑坝截流，开挖人工渠道，使水流改道绕过事故点，用机械铲除受污染沙土石，将大量水泥石灰倒入事故点床底并搅拌，固化处理床底中无法清除的受污染沙土石。本发明可广泛的适用于各种水源地的水质保护，给下游居民的饮水安全带来了保障。

Description

一种用于被三氧化二砷污染水源后的应急处置方法
技术领域本发明涉及一种水源污染后的应急处置方法，具体为一种用于被三氧化二砷污染水源后的应急处置方法。
背景技术三氧化二砷也称砒霜有剧毒，是工业生产和农业制药的重要化工原料，用途广泛，随着交通运输业的发展，也给水源地的保护带来了安全隐患，一旦其污染水源将会严重威胁下游居民的饮水安全。
发明内容本发明一种用于被三氧化二砷污染水源后的应急处置方法，能有效地解决上述问题，旨在提供一种安全高效的应急处置方法。
本发明的目的通过下述技术方案予以实现；它包括在受污染水体中投加大量的石灰中和沉淀，在事故点上游筑坝截流，开挖人工渠道，使水流改道绕过事故点，用机械铲除受污染沙土石，将大量水泥石灰倒入事故点床底并搅拌，固化处理床底中无法清除的受污染沙土石。
具体实施方式下面对本发明作进一步描述，当确认被三氧化二砷污染水源后，迅速采取上述措施，并随时检测下游水质变化情况，一旦发生变化，立即通知下游用水单位。
本发明可广泛的适用于各种水源地的水质保护，给下游居民的饮水安全带来了保障。
