In chinese north cities , more than 70 % of drinking water resource is surface water which has been seriously polluted by organic matters and algae 我国北方城市水源70以上为地表水，有机物污染严重，藻类大量繁殖，各种浮游动物孳生，常规处理工艺无法满足安全饮用水供应的需要。
In recent years , yellow river has been seriously polluted by organic pollutants , and existing water treatment technology can not effectively remove organic pollutants from yellow river 近年来，黄河水中有机物污染日趋严重，现有的给水处理工艺不能有效去除黄河水中的有机污染物。
In general , a surface soiled with something of a mineral nature can be effectively cleaned with an acidic detergent , whereas alkaline detergents are used for surfaces soiled with organic matter 一般而言，被具有无机物特性的物质污染的表面可使用酸性去污剂有效清洁，反之，碱性去污剂用于清洁被有机物污染的表面。
