【摘要】 本文报道上流式厌氧消化器处理城镇粪尿上层液的卫生效果。消化器为污泥床与过滤器的结合体,有效容积20升,在室内试验处理城镇粪水,采用53±1℃发酵,在进料粪水中,人为加入相当数量的肠道致病菌活茵,泵入厌氧消化器,滞留仅6小时,从排出液中,即已不能检出活的致病菌。大场菌值由10^-5～10^-3升为>11.1～10^-1。每100ml排出液中仅有寄生虫卵0.04个,且均为死卵,取得了显著的卫生效果。更多还原

【Abstract】 The excreta collected fr°m tOwnship were experimentally treated by upflow anaerobic digester consisting of sludge bed and filter with an effective capacity of 20 liters, The fermentation temperature was 53 + 1℃. The inlet excreta m which a great number of living intestine pathogenic bacteria was artificially added, were pumped into the digester. 6 hours after treatmeut, no living pathogenic germ and only 0.04 dead Parasitic egg/100 ml could be detected in the outlet samples. The c°lititer turned 10^-5-10^-3into 11.1-10^-1.更多还原
