摘　　要：本文简单介绍了饮用水管网“红水”现象的成因和控制方法 ,采用投加碱液的方法进行水质稳定处理 ,适当地提高水的 p H值、碱度和钙离子含量 ,可以有效地降低水的腐蚀性。旋转挂片腐蚀失重试验的结果表明 。The mechanism and methods of controlling corrosion induced reddening of drinking water of in water distribution systems were briefly reviewed. A laboratory study was conducted to evaluate the effectiveness of addition of several alkaline solutions to increase the pH, alkalinity and Ca 2+ of water to reduce its corrosiveness. The results of coupon weight-loss corrosion experiments indicated that water stabilization could be a successful way to control corrosion in water distribution systems and minimize or eliminate reddening of drinking water.
