  • 摘要: 有机物、总磷是我国地表水源主要污染物,涉及范围广,污染浓度高,是影响水厂出水安全的重要因素。以某水厂净水系统为依托,分析水厂常规工艺对有机物和总磷的去除效果及影响因素。研究表明,地表水源水厂所采用的混凝+沉淀+过滤+消毒的传统工艺对有机物的去除率不高,在22.1%～61.3%之间,平均去除率为38.3%;其中,混凝沉淀是常规工艺中去除CODMn的关键环节,占总去除效果的43%～68%,过滤环节去除率约为10%;温度和混凝剂投加量是影响CODMn去除效果的主要因素。常规工艺对总磷的去除效果较好,去除率约为60%～90%,冬季略低,其他季节略高;混凝沉淀单元与过滤单元对总磷均有较好的去除效果,去除率分别为25%～77%和40%～76%。在当前水质条件下,水厂现行工艺可满足常规状况下有机物和总磷的去除需要。
    Abstract: Organic compounds and total phosphorus are the main pollutants of surface water and usually cause serious pollutions with large area and high concentration. So they are the important factors for water supply security. Based on the purification system of a water plant, the removal effects of CODMn and total phosphorus and the influencing factors under conventional process are discussed. It is proved that the removal rate of CODMn is from 22.1% to 61.3% and the average value is about 38.3%. Coagulation sedimentation plays a very important role in CODMn removal and the ratio of its removal rate to total value ranges from 43% to 68%. But for filtration it is only 10%. Temperature and coagulation dosing are the main influencing factors. The removal rate of total phosphorus under conventional process is much higher and it is from 60% to 90%. The effects of coagulation sedimentation and filtration are both good and their removal rates are almost the same. One is from 25% to 77%, and the other is from 40% to 76%. Therefore, for current water quality the conventional process of surface water plants can meet requirements of the removal of organic compounds and total phosphorus.
