【摘要】 本文报道用石英粉吸附——洗脱法浓集污水病毒,其回收率为51～90％。对1985年3～7月采集的不同水样进行病毒分离和蚀斑滴定,结果表明,高碑店污水系统中的病毒大部分为肠道病毒。春季以脊髓灰质炎病毒为主,夏季以柯赛奇B3及非肠道病毒为主。不同类型污水中的病毒浓度依次为:原污水58PFU/1;二级污水<19,约为9PFU/1;医用污水<16,约为1PFU/1,地下水<1.7PFU/1,未检出病毒。夏季水样内病毒浓度较春季低。更多还原

【Abstract】 About 40% municipal wastewater of Beijing city was converged into Gao-beidian wastewater system.For detecting the comtaminated viruses in the system, we adopted adsorption-elution technique with quartz powder to concentrate viruses fron the water samples.The recovery efficiency was 51-90%. Water samples collected from March to July 1985 were used for virus isolation and plaque assay. The results indicate that the contaminated viruses in the wastewater system were mostly enteroviruses with seasonal variations, polio-viruses mainly in spring,while mostly coxsackievirus B3 and non-enterovirus-es in summer.The concentration of viluses in vastewater was higher in the spring than in the summer. The average virus concentration in different waters were as follows: raw wastewater ( 58 pfu/1 ) , effluent of biological oxidation treatment ( <19, about 9 pfu/1), Hospital sewage ( <16, about 1 pfu /1 ) , ground water ( <2 pfu/1, undetectable ) .更多还原
