采集经三格粪池初步处理的粪水,测定加氯前后的细菌总数、粪大肠菌数,并进行Ames试验,结果表明加氯消毒效果是理想的,但同时产生了强致突变性。作者认为应对粪水加氯消毒的得失重新全面评价。 A preliminary test of the manure collected from the three-septic tank was carried out to determine the total number of bacteria and the number of fecal coliform bacteria before and after chlorination. Ames tests were conducted. The results showed that the chlorination effect was ideal, but strong mutagenicity was also observed. The author believes that the success or failure of chlorination of manure should be re-evaluated.
