据近年调查,海军沿海、岛屿部队的少数饮用水源受生活污水和农药的污染,色度、浊度超过生活饮用水标准的占30%左右,约有80%的水源不经消毒处理而直接饮用。为给分散部队提供结构简单、便于推广、能解决100～150人的食堂饮用水净化的装置,开展了生活饮用水净化装置的研制工作。经过滤材的筛选试验,反冲洗方式的选择试验,不同规格型号的消毒元件的比较选择等试验,研制成适于分散部队用的Hy-84型饮用水净化消毒装置,经部队现场试用,于1986年7月通过技术鉴定。
According to recent surveys, a few of the drinking water sources of coastal navy and island units are polluted by domestic sewage and pesticides. Chrominance and turbidity exceed the standard of drinking water by about 30%. About 80% of the water is directly discharged without disinfection drink. In order to provide decentralized units with a simple structure and easy popularization, it is capable of solving the problem of purifying drinking water in canteen of 100 to 150 persons and carrying out research and development work on the purification device of domestic drinking water. After screening test of filter material, selection test of backwashing method, comparison and selection of disinfecting elements of different specifications and models, Hy-84 type drinking water purifying and disinfecting device suitable for decentralized troops was developed and tested on site by the troops July 1986 passed the technical appraisal.
