摘要
使用过乙酸处理私人住宅的化粪池及粪坑污水(1～2g/L),在污水中加入1g/L过乙酸不仅操作简便,而且发现肠道指示微生物被有效去除。仔细混合过乙酸和污水非常重要。冬季冻土、冰、雪不构成特别的问题。经过处理的污水臭味几乎全部消失。经过乙酸处理的污水倒入牲畜泥浆池时,在牲畜泥浆和污水的混合中仍然有卫生化作用。这种污水可以排放到农田土壤中,没有微生物污染地下水的危险。
Wastewaters of private household septic tanks and cesspools have been treated with peracetic acid (1-2 g L-1). Adding 1 g L-1 peracetic acid to wastewaters was easy and has been found to be effective in destroying enteric indicator microorganisms. The careful mixing of peracetic acid and wastewater was found to be important. Winter periods with frozen soil, ice and snow did not constitute extra problems. The bad smell of these wastewaters almost totally disappeared during the treatment. When wastewaters treated with peracetic acid were emptied into animal slurry tanks, hygienization still continued in the mixture of animal slurry and the wastewaters. These wastewaters could thus be released into agricultural soil without risk of microbiological pollution to groundwaters.
