【摘要】：目的为缺乏安全用水的贫困地区设计一种砂滤式水净化处理洗手装置,以培养当地居民的良好个人卫生习惯,预防疾病的发生。方法选取坚固耐用、成本低廉的装置外壳材料,确定砂粒滤料的配比,按照GB/T 5750.12—2006《生活饮用水标准检验方法微生物指标》中规定的微生物指标检测方法对洗手装置加标水样进水、出水的菌落总数、大肠埃希菌、贾第鞭毛虫孢囊进行检测。结果装置外壳材料选用PP塑料板,砂粒滤料为40~100目,出水水样中菌落总数去除率可达约90%,大肠埃希菌、贾第鞭毛虫孢囊的去除率均为100%。结论该洗手装置可使用普通地表水作为进水,能满足多口之家一天的洗手用水量。该装置组建简单,滤料等可当地取材,成品易操作,适用于供水资源短缺地区或没有管道供水的居民生活使用。
[Abstract]:Objective to design a sanded water cleaning and washing device for poor areas lacking safe water in order to cultivate the good personal hygiene habits of local residents and prevent the occurrence of diseases. Methods selecting durable and low cost shell material to determine the proportion of sand filter material. According to the microbiological index of the standard test method for drinking water of GB/ T 5750.12-2006, the total number of colonies, Escherichia coli and Giardia lamblia spore sac in the standard water sample of hand-washing device were detected. Results PP plastic plate was used as shell material, sand filter material was 40 ~ 100 mesh, total colony removal rate of effluent water was about 90. The removal rate of Escherichia coli and Giardia flagellate cyst were 100. Conclusion this hand washing device can use the common surface water as the influent, and can satisfy the daily water consumption of many families. The device is simple to set up, the filter material and so on can be obtained locally, the finished product is easy to operate, and it is suitable for the residents living in areas where water resources are short or where there is no pipeline to supply water.
