摘要
人工模拟农村生活污水,通过添加炉渣和不添加炉渣,并设置不同温度(15℃、25℃和35℃)下静滞和摇动处理,探讨炉渣净化农村生活污水的条件和效果。结果表明,污水经过炉渣静滞净化吸附后,污水中的TN、NH_(3)-N、TP以及COD都有一定的降低,且随温度的升高,炉渣去除污水中TN、NH_(3)-N、TP以及COD的作用越大,在35℃下去除率分别达到了4.9%、63.2%、94.5%和64.7%。如果加炉渣的生活污水再以一定的频率摇动,能有效地提高炉渣对污水中NH_(3)-N的去除,去除率达到了90.0%,但对TN、TP以及COD的去除率有所下降。
The conditions and effects of slag on the purification of rural domestic sewage were studied by adding slag or not,shaking treatment or not,under different temperatures(15℃,25℃and 35℃).The results showed that the TN,NH_(3)-N,TP and COD in sewage were reduced after the adsorption of slag without shaking treatment.The removal amount of TN,NH_(3)-N,TP and COD in sewage from slag increased with temperature.The removal rates of TN,NH_(3)-N,TP and COD in sewage by slag reached 4.9%,63.2%,94.5%and 64.7%respectively at 35℃.The removal rate of NH_(3)-N in sewage could effectively be improved to 90.0%by the adsorption of slag with shaking treatment,while the removal rate of TN,TP and COD decreases somewhat.
