作者检测了两个小规模处理系统(巴氏消毒系统和隐化池系统)的病毒含量,同时比较了四种不同方法(直接接种法,酸沉淀法,明矾沉淀法和两相分离法)检测病毒的效能。研究地点为Tvind学校。隐化池系统是用来处理来自浴室、厨房和厕所污水的混合物的,能使水体被排放到小河之前,BOD下降30%。巴氏消毒系统是用来处理含有大量悬浮固体的污水的,其过程是污水与甲醛(最终浓度为170～200 mg/l)混合,其后立即在76℃,30分钟进行巴氏消毒。从隐化池系统和巴氏消毒系统采集进水和出水样品;另外在Damhusaaen
The authors examined the virus content of two small-scale processing systems (pasteurization and insolation systems) and compared four different methods (direct seeding, acid precipitation, alum precipitation and two-phase separation) The effectiveness of the virus. The study site is Tvind School. The hidden pool system is designed to handle a mixture of sewage from the bathroom, kitchen and toilet and to reduce the BOD by 30% before the water is discharged to the stream. The pasteurization system is designed to treat wastewater containing a large amount of suspended solids by mixing wastewater with formaldehyde (final concentration 170 to 200 mg / l) and immediately thereafter pasteurizing at 76 ° C for 30 minutes. Samples of influent and effluent were taken from the invader system and the pasteurization system; in addition to the Damhusaaen
