目前,国内外对车载野外饮水净化装置研究较多。虽然该装置能对野外水源进行有效净化处理,但存在装置体积大,能耗大,成本高,携带不便等问题。因此,笔者研发了一种新型车载野外饮水净化装置。该装置系统由前处理单元、净化单元、箱体和电控单元四个部分组成。前处理单元是对原水进行沉淀和消毒处理。采用的沉淀剂为聚丙烯酰胺和聚合氯化铝混合物,用来沉淀原水中的悬浮物及其他杂质。消毒剂采用二氧化氯,用来去除原水中的细菌、病毒等微生物。使用时将两者一起倒入车载水桶中与水搅拌,消毒10 min后可进入净化装置进行净化。净化单元是对预处理后的原水进行粗滤和深层净化处理,包括抽水泵、5μmPP棉和活性碳复合过滤器以及1μm PP棉
At present, the domestic and foreign research on vehicle-mounted outdoor drinking water purifiers are more. Although the device can effectively purify the water source in the field, there are problems such as large device size, high energy consumption, high cost and inconvenient portability. Therefore, I developed a new vehicle field drinking water purification device. The device system consists of pre-treatment unit, purification unit, cabinet and electronic control unit composed of four parts. Pre-treatment unit is the raw water sedimentation and disinfection. The precipitating agent used is a mixture of polyacrylamide and polyaluminum chloride, used to precipitate suspended solids and other impurities in raw water. Chlorine dioxide disinfectant used to remove bacteria, viruses and other microorganisms in raw water. When using the two together into the car bucket and water mixing, disinfection 10 min can enter the purification device for purification. Purification unit is the raw water after pretreatment of coarse filtration and deep purification, including the pump, 5μmPP cotton and activated carbon composite filter and 1μm PP cotton
