目的 针对以黄河为生活饮用水源的污染因素 ,研究改善水质的防治措施和净水工艺。方法采取对城市污水截流改道 ,在制水过程中增加低脉动混凝沉淀给水技术、使用杀藻剂、挖泥清淤及活性炭吸附等工艺。通过对照研究和统计学处理 ,对防治措施和制水工艺的效果作出评价。结果 出厂水达到国家《生活饮用水卫生标准》 ,藻毒素含量降至对人体危害水平以下。结论 使用杀藻剂使水源藻密度降低、藻毒素含量升高 ,降浊、投放活性炭等工艺对改善水质作用显著
Objective To study the pollution prevention and control measures to improve the quality of the drinking water in the Yellow River and the water purification process. Methods Aiming at diversion and diversion of urban sewage, low pulsation coagulation sedimentation water supply technology was added in the process of making water, and algicides, dredging and activated carbon adsorption were used. Through comparative studies and statistical analysis, the effect of prevention and control measures and water-making technology are evaluated. Results Factory water to reach the national “drinking water health standards”, algae toxin content reduced to the level of human health hazards below. Conclusion The use of algicide to reduce the water density of algae, algae toxin content increased, turbidity, put activated carbon and other processes on the improvement of water quality significantly
