1984年本刊第5期所登的“一种加氯消毒法”提到将继续进行取消接触池的试验,我们在继续试验中所用的加氯方法,设备与文中介绍的方法相同,从1981年8月起先是在接触池前部的反应池中取样化验,共作了细菌检测29次,平均大肠杆菌指数为16.7个/升,最高为161个/升,从上述结果可以看出,处理后的污水符合医院污水排放标准中总大肠菌群数每升不得大于500个的要求。为了更准确的反映试验结果,我们于1983年7月进行了取消接触池的运行试验。具体的做法是虹
The “chlorination method” enshrined in the 1984 issue of the 5th issue of the journal mentions that the trial to cancel the contact pool will continue. The chlorination method used in the continuation of the test is the same as that described in the article, from 1981. In August of this year, a sample was taken from the reaction pool in the front of the contact tank. A total of 29 bacterial tests were performed. The average E. coli index was 16.7 per litre and the highest was 161 per litre. From the above results, it can be seen that The post-contaminated water meets the requirement that the number of total coliform bacteria in the hospital’s wastewater discharge standard should not exceed 500 per litre. In order to more accurately reflect the test results, we conducted a test to cancel the contact tank in July 1983. The specific approach is rainbow
