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 ,这种方法可以取得满意的缓蚀效果 This article briefly introduced the cause and control method of “red water” phenomenon in drinking water pipe network. Stabilizing the water quality by adding lye can improve the p H value, alkalinity and calcium ion content of water, which can effectively Reduce water corrosion. The results of corroded weight loss test of rotating coupons show that this method can achieve satisfactory corrosion inhibition effect
