| 摘 要： | 以斑马鱼胚胎毒性测试研究海南某污水处理厂出水经氯胺、二氧化氯、次氯酸钠、臭氧和紫外几种消毒处理后对斑马鱼胚胎的毒性。利用胚胎毒性和层次分析法构建危害分级方法及其指标体系,评价消毒危害。研究结果表明:消毒处理前的二沉池出水未产生胚胎发育毒性效应,但经次氯酸钠、氯胺、臭氧、二氧化氯对再生水消毒处理可使斑马鱼胚胎出现卵黄囊异常、心跳减缓、色素沉积减少、孵出延缓和卷尾等毒理反应;不同消毒方式处理的再生水可致斑马鱼胚胎死亡率增加,胚胎毒性依次为:二氧化氯紫外紫外+次氯酸钠=二沉池出水(不消毒)氯胺=紫外+氯胺臭氧次氯酸钠;不同消毒方式的危害分级为:二氧化氯和紫外消毒构成轻微危害,危害等级为I级,紫外+次氯酸钠、紫外+氯胺、氯胺消毒构成中度危害,危害等级为II级,次氯酸钠危害较强,其危害等级为III级;化学消毒剂与紫外线组合消毒可降低再生水消毒的危害。
