As a result, reverse osmosis treatment technology has gradually been applied to drinking water treatment technology from the industrial field, and various reverse osmosis direct drinking water machines have been applied.

而反渗透净水机与其他净水器相比,有产生浓缩水的问题,反渗透净水机在工作时,一部分水经过膜过滤后,到达膜的另一端成为净化水,但另一部分含有杂质及有害物质的水被膜截留成为浓缩水,但通常的反渗透净水机净水效率较低,余下的大量浓缩水很多被当作废水排放掉或积聚在反渗透膜,且目前国内少有对提高反渗透净水机效率进行系统的研究,随着消费者对反渗透净水机的认可,以及反渗透膜和净水整机制造商技术的提升,反渗透净水机已朝着节水、低压、大流量的方向发展。Compared with other water purifiers, the reverse osmosis water purifier has the problem of producing concentrated water. When the reverse osmosis water purifier is working, part of the water is filtered through the membrane and reaches the other end of the membrane to become purified water, but the other part contains The water with impurities and harmful substances is retained by the membrane to become concentrated water, but the water purification efficiency of the usual reverse osmosis water purifier is low, and a large amount of the remaining concentrated water is discharged as waste water or accumulated in the reverse osmosis membrane.

石英砂过滤器属于压力式过滤器设备,利用石英砂过滤介质,在一定的压力下,使原液通过该介质,经过滤料之间的孔隙截流和浮获而达到过滤的目的,过滤液体沿滤料间缝隙流过,杂质被逐步截留,属于薄膜过滤,滤除水中悬浮物,不溶性颗粒物,絮状沉淀等异物、脱色去味,滤料缝隙对悬浮物起筛滤作用使悬浮物易于截留在滤料表面,当在滤料表层截留了一定量的污物形成滤膜,随时间推移过滤器的前后压差将会很快升高,直至失效,利用反冲洗方式将滤层中截留杂质,冲出过滤器,恢复初始过滤功能。Quartz sand filter belongs to pressure type filter equipment. It uses quartz sand to filter medium. Under certain pressure, the raw liquid passes through the medium, and is intercepted and floated by the pores between the filter materials to achieve the purpose of filtering. The filtered liquid is filtered along the filter. The gaps between the materials flow through, and the impurities are gradually retained. It belongs to membrane filtration, which filters out suspended solids in water, insoluble particles, flocculent sediments and other foreign matters, decolorizes and deodorizes, and the gaps of the filter media play a role in sieving the suspended solids, so that the suspended solids are easy to be trapped in. On the surface of the filter material, when a certain amount of dirt is retained on the surface of the filter material to form a filter membrane, the pressure difference between the front and rear of the filter will increase rapidly over time until it fails. The backwash method is used to trap impurities in the filter layer, Flush out of the filter to restore the original filtering function.

活性炭过滤器12和石英砂同属于压力式过滤器设备,其设备操作及反洗等操作基本一致,利用活性炭作为过滤介质,在一定的压力下,使原液通过活性炭,经过活性炭滤料吸附原水中色素、异味及水中余氯,为下一级RO反渗透系统保驾护航,当活性炭吸附一段时间后会饱和失效,这时需要反冲洗活性炭,排出吸附污垢方可继续使用。Activated carbon filter 12 and quartz sand are both pressure filter equipment, and their equipment operations and backwashing operations are basically the same. Using activated carbon as a filter medium, under a certain pressure, the raw liquid passes through the activated carbon, and the activated carbon filter material adsorbs the raw water. Pigment, peculiar smell and residual chlorine in the water will escort the next-level RO reverse osmosis system. When the activated carbon is adsorbed for a period of time, it will be saturated and invalid. At this time, the activated carbon needs to be backwashed and the adsorbed dirt can be discharged before continuing to use.

保安过滤器13的作用是截留过滤器产水中泄的大于5μm的颗粒,防止其进入反渗透过滤室15,这种颗粒经高压泵14加速后可能会击穿反渗透膜26组件,造成大量漏盐的情况,同时划伤高压泵14 的叶轮,过滤器中的滤元为可更换卡式滤棒,当过滤器进出口压差大于设定值通常为0.07~0.1Mpa时应当更换。The function of the security filter 13 is to intercept the particles larger than 5 μm leaked from the filter product water and prevent them from entering the reverse osmosis filter chamber 15. Such particles may break down the reverse osmosis membrane 26 components after being accelerated by the high pressure pump 14, resulting in a large amount of leakage. In the case of salt, the impeller of the high-pressure pump 14 is scratched at the same time. The filter element in the filter is a replaceable cartridge filter rod. When the pressure difference between the inlet and outlet of the filter is greater than the set value, it should be replaced.

反渗透过滤室15:对透过的物质具有选择性的薄膜称为半透膜,一般将只能透过溶剂而不能透过溶质的薄膜称之为理想半透膜,当把相同体积的稀溶液(例如淡水)和浓溶液(例如盐水)分别置于半透膜的两侧时,稀溶液中的溶剂将自然穿过半透膜而自发地向浓溶液一侧流动,这一现象称为渗透,当渗透达到平衡时,浓溶液侧的液面会比稀溶液的液面高出一定高度,即形成一个压差,此压差即为渗透压,渗透压的大小取决于溶液的固有性质,即与浓溶液的种类、浓度和温度有关而与半透膜的性质无关,若在浓溶液一侧施加一个大于渗透压的压力时,溶剂的流动方向将与原来的渗透方向相反,开始从浓溶液向稀溶液一侧流动,这一过程称为反渗透,反渗透是渗透的一种反向迁移运动,是一种在压力驱动下,借助于半透膜的选择截留作用将溶液中的溶质与溶剂分开的分离方法,它已广泛应用于各种液体的提纯与浓缩,其中最普遍的应用实例便是在水处理工艺中,用反渗透技术将原水中的无机离子、细菌、病毒、有机物及胶体等杂质去除,以获得高质量的纯净水。Reverse osmosis filtration chamber 15: The membrane that is selective for the permeated substances is called a semi-permeable membrane. Generally, a membrane that can only permeate a solvent but cannot permeate a solute is called an ideal semi-permeable membrane. When a solution (such as fresh water) and a concentrated solution (such as salt water) are placed on both sides of a semipermeable membrane, the solvent in the dilute solution will naturally pass through the semipermeable membrane and flow to the concentrated solution side spontaneously, a phenomenon called osmosis. , when the osmosis reaches equilibrium, the liquid level of the concentrated solution will be higher than that of the dilute solution by a certain height, that is, a pressure difference will be formed. This pressure difference is the osmotic pressure. The size of the osmotic pressure depends on the inherent properties of the solution. That is, it is related to the type, concentration and temperature of the concentrated solution and has nothing to do with the properties of the semipermeable membrane. If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the flow direction of the solvent will be opposite to the original permeation direction, starting from the concentrated solution. The solution flows to the side of the dilute solution. This process is called reverse osmosis. Reverse osmosis is a reverse migration movement of osmosis. The separation method separated from the solvent has been widely used in the purification and concentration of various liquids. The most common application example is in the water treatment process, using reverse osmosis technology to remove inorganic ions, bacteria, viruses, organic substances in raw water. And impurities such as colloids are removed to obtain high-quality purified water.

控制器41:根据供水项目水处理站的工程特点及系统配置,系统目前采用常规的电气联动控制方式对系统进行控制,考虑到控制系统存在液位、压力、水质及反渗透内部及水泵之间联动控制系统反渗透装置设置PLC(可编程控制器41)进行编程控制确保系统的稳定可靠,为了提供系统的可监控性,电控系统设置流程控制屏随时监视整个系统用电设备的运行情况;Controller 41: According to the engineering characteristics and system configuration of the water treatment station of the water supply project, the system currently uses a conventional electrical linkage control method to control the system, considering that the control system has liquid level, pressure, water quality and reverse osmosis inside and between pumps The reverse osmosis device of the linkage control system is equipped with PLC (programmable controller 41) for programming control to ensure the stability and reliability of the system. In order to provide the monitorability of the system, the electronic control system is equipped with a process control screen to monitor the operation of the electrical equipment of the entire system at any time;
