【摘要】 中水技术开发既可缓解水资源的紧缺,又能改善城市环境。本文报道用石英粉吸附/洗脱和浓缩棒脱水的二步浓集水病毒技术(回收率为25.4～37.3％),研究中水技术不同处理工艺去除病毒的效果。结果,二级处理可去除掺入病毒的98.9％,结合三级处理的混凝沉淀和过滤,可去除99.976％,再加活性炭吸附或加氯消毒,所得中水分别去除掺入病毒的99.986％和99.991％。经首都机场中水道试验厂水样检测表明,中水中未检测到病毒(<0.23PFU/L)。更多还原

【Abstract】 The increasing need to reuse water now call for advanced wastewater treatment. New processes have been developed to purify the sewage to a desired degree. For evaluating virai removal of the processes we adopted ad-sorption-elution with quartz powder and dehydration with high polymers tech nique to concentrate viruses from water samples with recovery efficiency of 25.4-37.3%. The treatment processes were found to be efficient in reduc-ing contaminated viruses to undetectable Ievel ( <0.23PFU/L ) in a pilot plant ( 10 tons a day in scale ) . The result of experimentally-seeded polio virus I indicates that the efficiency of virai removal by activated-sludge treatment, coagulation-sedimentation and filtration with dual medium filters,and chlorination was 98.9%, 97.8% and 63.3% respectively. The total virairemoval can reach 99.991%.更多还原
