作为纯净水生产的依托是非常重要的。所以要生产纯净水一定是要选择原水水质比较好的地方。如山泉、深井等。在这里牵扯到一个非常重要的指数就是“电导率”，一般而言电导率越低，水越纯净。水处理工艺都是采用的反渗透系统，经过处理后的水一般能达到90%——99%的脱盐率；下面我介绍一下这个系统的组成部件。
As a support for the production of purified water, it is very important. So to produce pure water, it is necessary to choose a place with good raw water quality. Such as mountain springs, deep wells, etc. A very important index involved here is "conductivity". Generally speaking, the lower the conductivity, the purer the water. The water treatment process adopts reverse osmosis systems, and the treated water can generally achieve a desalination rate of 90% -99%; Below, I will introduce the components of this system.
1、原水泵
1. Raw water pump
原水泵是为原水预处理系统提供原水压力的作用。如果原水有压力就完全可以不用这个设备。一般要求原水压力>=0.3MPa
The raw water pump serves to provide raw water pressure for the raw water pretreatment system. If the raw water is under pressure, this equipment can be completely eliminated. General requirement: Raw water pressure>=0.3MPa
2、原水箱
2. Raw water tank
原水箱的作用更简单，是储存原水用的。这是怕原水万一供不上作一个中转（通常添加浮球开关是整个系统自动化程度更高）。
The function of the raw water tank is simpler, it is used to store raw water. This is because we are afraid that if the raw water cannot be supplied, it will be used as a transfer (usually adding a float switch will increase the automation level of the entire system).
3、石英砂过滤器
3. Quartz sand filter
采用石英砂滤料以除去原水中较大颗粒的悬浮物、泥沙、杂质等，降低水的混浊度。而且还可以使水中的有机物质、细菌、病毒等随着浊度的降低而被大量去除，并为滤后消毒创造了良好条件。
Using quartz sand filter material to remove suspended solids, sediment, impurities, etc. of larger particles in the raw water and reduce water turbidity. Moreover, it can also remove a large amount of organic substances, bacteria, viruses, etc. in the water as the turbidity decreases, and create good conditions for disinfection after filtration.
4、活性炭过滤器
4. Activated carbon filter
利用活性碳的吸附能力有效地吸附原水中的有机物、游离性余氯、胶体、微粒、微生物、某些金属离子及脱色等。
Utilize the adsorption capacity of activated carbon to effectively adsorb organic matter, free residual chlorine, colloids, particles, microorganisms, certain metal ions, and decolorization in raw water.
5、软化系统（加药系统）
5. Softening system (dosing system)
利用离子树脂的交换性能，除去原水中的钙镁离子，以达到防止后继设备结生水垢的影响，但是操作起来费工，费料。改为加药系统直接向里添加阻垢剂。
By utilizing the exchange performance of ion exchange resins, calcium and magnesium ions in the raw water are removed to prevent the influence of scale formation on subsequent equipment. However, the operation is labor-intensive and material intensive. Change to adding scale inhibitor directly to the dosing system.
主要解决以下问题：
Mainly solve the following problems:
1、防止有机物污染；
1. Preventing organic pollution;
2、防止胶体物及悬浮固体微粒堵塞；
2. Prevent blockage of colloids and suspended solid particles;
3、防止氧化性物质对膜的氧化破坏；这样可保证反渗透装置稳定运行以及正常的使用寿命。
3. Prevent oxidative damage to the membrane by oxidizing substances; This can ensure the stable operation and normal service life of the reverse osmosis device.
4、防止反渗透膜面结垢CaCO3、CaSO4、SrSO4、CaF2、SiO2、铁、铝氧化物等在膜面沉积
4. Prevent the deposition of CaCO3, CaSO4, SrSO4, CaF2, SiO2, iron, aluminum oxides, etc. on the reverse osmosis membrane surface from scaling
