摘要
本文对应用氧化塘系统处理城市污水的净化效果进行了卫生细菌学、病毒学的系统评价,并结合我国的特点提出了氧化塘系统排放污水的卫生微生物学标准.
After three years' examination,we found that 10~7-10~8/L of fecal coliform bacteria, 10~3-10~5/L of salmonella, 10~1-10~2/L of ascaris eggs and 10~2-10~3 pfu/L of enterovirus were contained in municipal wastewater. The removal rates of bacteria and virus whether in winter and summer or in spring may reach 2 magnitudes respectively after 10 day's treatment if some heat preservation measure was taken in winter.We propose that the regulation of FC should be lower than 10~4/L and the ascaris egg's removal rate should be lower than 90% as the standards of the effluents from the acidifi stabilization ponds system, but the standard value of virus can not be determined yet.
