Description
技术领域technical field
本实用新型涉及一种家用或商用净水设备，尤其涉及一种节水型净水机，属于水处理技术领域。The utility model relates to a household or commercial water purifier, in particular to a water-saving water purifier, which belongs to the technical field of water treatment.
背景技术Background technique
净水机是一种采用多级滤芯对水质进行深度净化处理的设备，根据不同的净化原理和工艺，可以分为很多种类，如超滤、微滤、反渗透、离子交换、活性炭吸附等，过滤精度也有很大差异，其中，反渗透净水机是过滤精度最高的一种。由于反渗透膜的孔径仅为0.1纳米左右，只允许水分子通过，水中所含的杂质，如泥沙、铁锈、胶体、农药、重金属、放射性物质、水碱、细菌、病毒等有害物质可以全部被截留排除，因此，反渗透净水机受到了人们的普遍欢迎。Water purifier is a kind of equipment that uses multi-stage filter elements to purify water quality in depth. According to different purification principles and processes, it can be divided into many types, such as ultrafiltration, microfiltration, reverse osmosis, ion exchange, activated carbon adsorption, etc. There are also great differences in filtration accuracy, among which reverse osmosis water purifiers are the one with the highest filtration accuracy. Since the pore size of the reverse osmosis membrane is only about 0.1 nanometers, only water molecules are allowed to pass through, and the impurities contained in the water, such as sediment, rust, colloid, pesticides, heavy metals, radioactive substances, water alkali, bacteria, viruses and other harmful substances can be completely eliminated. Being intercepted and excluded, therefore, the reverse osmosis water purifier has been widely welcomed by people.
然而，由于反渗透膜特殊的净化原理和使用要求，在净化原水的过程中，会产生大量的盐分较高的“浓水”，浓水和净水的比例高达3:1，甚至更高，也就是说有70％以上的水都被直接排放掉了。其实，所谓“浓水”并不是废水，这部分水由于已经经过了前置滤芯的预处理，其卫生指标要优于自来水，只是含盐量较高不适合饮用，将“浓水”排入下水道，无疑是白白浪费了自来水。如果以每户家庭每个月使用300升纯净水计算，一个月将排放1吨浓水，这对于反渗透净水机已占据绝大多数市场的现状而言，造成了水资源的极大浪费。However, due to the special purification principle and application requirements of the reverse osmosis membrane, in the process of purifying raw water, a large amount of "concentrated water" with high salt content will be produced. The ratio of concentrated water to purified water is as high as 3:1, or even higher. That is to say, more than 70% of the water is directly discharged. In fact, the so-called "concentrated water" is not waste water. Since this part of water has been pretreated by the pre-filter, its sanitary index is better than that of tap water, but the high salt content is not suitable for drinking. The "concentrated water" is discharged into the The sewer is undoubtedly a waste of tap water. If each family uses 300 liters of pure water per month, 1 ton of concentrated water will be discharged in a month, which has caused a great waste of water resources in view of the current situation that reverse osmosis water purifiers have occupied the vast majority of the market .
