【摘要】：在5 000 m~3/d规模的生产性运行条件下,通过对微纳米陶瓷板曝气-活性无烟煤滤池与砂滤池在非排涝期和排涝期的运行效果进行比较。结果表明:非排涝期微纳米陶瓷板曝气-活性无烟煤滤池相比砂滤池,对臭和味、浊度、氨氮、有机物和消毒副产物的去除效果明显增加;排涝期改造后的滤池相比砂滤池,臭和味明显减弱,基本察觉不到臭和味,滤池改造后并不影响浊度的去除效果,滤后水平均浊度维持在0.5 NTU左右,对氨氮的去除率提高30%以上,对有机物的去除率提高约20%,三卤甲烷生成势降低约16%。非排涝期时改造滤池与普通石英砂滤池运行工况基本一致,无需启动微纳米曝气系统,不增加运行成本;排涝期时启动微纳米陶瓷板曝气系统,增加的水厂运行成本不高于0.1元/m3,运行效果良好,显著提升出水水质。
[Abstract]:Under the productive operation condition of 5 000 mm3 / d scale, the effects of aeration with active anthracite filter and sand filter on non drainage and waterlogging stage were compared by means of micro nano ceramic plate aeration and active anthracite filter. The results showed that the removal efficiency of odor, turbidity, ammonia nitrogen, organic matter and disinfection by-products was obviously increased compared with sand filter, and the effect of modified filter after waterlogging period was higher than that of sand filter, the results showed that compared with sand filter, the removal of odor, turbidity, ammonia nitrogen, organic matter and disinfection by-products was obviously increased in the micro-nano ceramic plate aeration-activated anthracite filter in non-drainage period. The odor and taste were obviously weakened, the odor and taste could not be detected, the removal efficiency of turbidity was not affected after the modification of filter, the average turbidity after filtration was maintained at about 0.5 NTU, and the removal rate of ammonia nitrogen was increased by more than 30%. The removal rate of organic matter was increased by about 20%, and the formation potential of trihalomethane was decreased by about 16%. The operation condition of the modified filter is basically the same as that of the ordinary quartz sand filter during the non-drainage period, and the micro-nano aeration system does not need to be started, and the running cost is not increased; during the waterlogging period, the micro-nano ceramic plate aeration system is started. The increased operation cost of the water plant is no more than 0.1 yuan / m ~ (3), the operation effect is good, and the effluent quality is improved significantly.
