摘要
研究了ClO2 作为消毒剂在去除医院污水中总大肠菌群数 (CFU)时的性能参数。实验结果表明 ,ClO2 加入量为 5— 8mg L、温度为 2 0— 30℃、接触时间为 30— 6 0min、pH为 7.8— 8.5、填料为组合型 ,是ClO2 去除CFU的最优参数 ,可使污水中CFU降至 5 0 0个 L ,达到国家一级排放标准 (GB8978- 1996 )。同时 。
In this paper, the property parameters of ClO 2 for removing the CFU in sewage from hospitals were studied. The results have shown: the amount of ClO 2 between 5 mg and 8 mg, the temperature between 20℃ and 30℃, the retention time from 30 min to 60 min, pH from 7 to 8 and combinative stuffing are the optimal parameters in removing CFU. The CFU in sewage can be reduced down to 500 after treatment, so that it can meet the national discharge standard. And this paper also analyzes the influence of those parameters on the removal rate of CFU.
