水中有机成分及其饮用水水质的影响李晓东蔡国庆马军摘要：M水中微量有机污染物和氯化消毒副产物对饮用水水质构成直接威胁，是饮用水中重点控制的有机成分；天然大分子有机物对水质构成间接影响，导致胶体稳定性提高、混凝剂药耗增加；藻类和代谢产物影响常规处理工艺效果，对水质产生不良影响。关键词：有机污染物消毒副产物天然有机物藻类随着我国经济的迅速发展，对水质与水量的要求愈来愈高。但由于受水土流失、水源污染等因素的影响，地表水成分逐渐趋于复杂，有机成分增多，给水处理难度增大。现行的常规给水处理工艺，难以去除水中对人体有害的多种微量有机污染物；此外，由于水土流失严重，水中天然有机物浓度也很高，不但对胶体产生严重保护作用，导致混凝剂药耗增加、水中铝的剩余量增高，而且产生大量的氯化消毒副产物，其中大部分对人体健康有较大的危害；由于水体受到污染，导致富营养化，藻类过量繁殖，产生难闻的嗅味和有害的藻毒素。如何经济有效地解决这些问题是给水处理领域所面临的一项重要任务。1饮用水中微量有机污染物饮用水中机污染物的来源可主要分为三个方面：工业废水和生活污水排放、大气污染、城市与农田径流。我国污水处理率很低，加上现有处理设施运行效率不高，使约80%左右的污水未经妥善处理即被排放到附近水体。据统计，我国82%的河流受到不同程度的污染。在我国的主要水域，如海河、辽河、淮河、巢湖、滇池、太湖等污染更为严重。大气污染造成的水源污染问题近些年来逐渐引起人们的重视，汽车尾气排放的碳氢类污染物参与光化学反应产生光化学烟雾，生成一些对人体有害的有机污染，随着降雨等途径进入到地表水体中。城市地表径流使一些有机污染物进入到水体，农田径流将农药和化肥等成分引入到水体中。虽然微量有机污染物的浓度很低（一般在ng/L～µg/L范围），仅占水中有机物总量的很少一部分（一般<10%，以总有机碳或高锰酸盐指数等综合指标计），但种类繁多、对人体危害较大，具有较高的致突变活性。据统计，在我国的七大水系中，不适合作饮用水源的河段已接近40%；城市水域中78%的河段不适合作饮用水源；约50%的城市地下水受到污染，水源污染加剧了水资源短缺的矛盾。目前我国绝大部分水厂仍采用传统的处理工艺，不能有效地去除以溶解状态存在的微量有机污染物，致使一些有害物质，包括致癌、致畸、致突变等微量有机污染物残留在饮用水中。2大分子天然有机物
