摘要
分析了常规水旋澄清池处理工艺.提出了增加投药器、改变投药方式和改造水旋澄清池进水方式的强化措施.实验结果表明,水旋澄清池经强化技术改造后,黄河水中浊度、有机物、氨氮的去除率均有了较大提高.为水厂在黄河水较高浊度期的正常供水提供了技术保障.
The technology of water-power whirling clarifier is summarized. Several techniques which can enhance coagulation, such as adding chemicai feed machine, changing the method of chemical feed, improving the influent mode,are brought up. The experimental result indicates that the removal efficiency of turbidity,organic compounds and ammonia nitrogen in the source water from the Yellow River is enhanced by the strengthening coagulation. At the same time, the outflow quality is improved.
