摘要
[目的 ]雨水是浙江省沿海农村居民家庭的主要饮用水源之一 ,为保证居民饮用雨水的卫生质量 ,采用管道式净水器 ,对雨水柜水质进行净化效果观察及技术经济研究。 [方法 ]于丰水期和枯水期对管道式净水器的原水和出水进行水质监测。 [结果 ]雨水柜水质的感官和一般化学指标尚能符合饮用水卫生标准要求。丰水期雨水柜水的细菌总数和总大肠菌群合格率仅为 2 0 %和 3 0 % ,但经净水器净化后都能符合国家生活饮用水卫生标准要求。雨水耗氧量 1.91～ 2 .2 1mg/L,其去除率 9.5 %～ 2 1.8% ;总有机碳和腐殖酸的去除率分别为 12 .1%和 13 .1%。净水总量可达 10 t左右 ,按成本计算每处理 1L 水仅花 2分钱。 [结论 ]管道式净水器净化饮用水具有使用方便 ,效果可靠和日常运行成本低等优点 ,是家庭较为理想的净水装置。
Rain water was the main drinking water source for rural population in the coastal areas of Zhejiang province To ensure the sanitary quality of drinking rain water,observation and technical economic analysis on the effectiveness of water treatment of water storage tank by tubular water purifier were carried out The sanitary qualities of source water and finished water of tubular water purifier were monitored during plenty water period and low water period The organoleptic and general chemical parameters of the storage tank water still met the sanitary standard of the drinking water The qualified rate of total count of bacteria and total coliform was only 20% and 30% for the storage tank water in plenty water period respectively These two microbiological parameters could meet the National Sanitary Standard for Drinking Water after the treatment by water purifier The values of chemical oxygen demand (COD) of raw rain water reached to 1 91~2 21 mg/L The removal rates induced by water purifier were 9 5%~21 8% for COD,12 1% and 13 1% for total organic carbon and humic acid respectively The total capacity of each water purifier reached to about 10 tons The cost of purified water was 0 02 yuan per liter [Conclusion]Tubular water purifier presented some advantages as follows:convenient operation,reliable effectiveness and low cost for operating and maintenance etc.So it was an ideal domestic water purifier
