| 一、反渗透设备基本原理 First, the basic principle of reverse osmosis equipment 反渗透膜分离技术（简称RO技术）是渗透的相反过程，其原理是水与溶液以渗透膜相隔，水侧向溶液渗透，两相之间有渗透压。若在溶液相上加压大于渗透压，则溶液相中的水就会向水相反方向渗透过去。利用反渗透而取得脱盐水，即原水在足够的压力下，通过渗透膜而变成纯净的水，没有通过膜的水溶解物、悬浮物浓度逐渐增大。 Reverse osmosis membrane separation technology (referred to as RO Technology) is the opposite process of penetration. Its principle is that water and solution are separated by osmosis membrane, and water is penetrated by lateral solution, and there is osmotic pressure between two phases. If the pressure is greater than the osmotic pressure in the solution phase, the water in the solution phase will permeate the water in the opposite direction. The reverse osmosis is used to get the desalted water, that is, the raw water becomes pure water through the permeable membrane under enough pressure, and the concentration of the dissolved matter and suspended matter increases gradually without the membrane. 对于一个特定的纯水系统，其性能的长期稳定是不可缺少的，RO系统的长期性能的成功取决于正常的操作与维护，包括整套系统的试车，开始运转与关机、清洗与保养等，膜面污垢和水垢预防不仅在预处理设计上要考虑，合适的操作也极为关键，同时记录的保存及RO运行参数日报表非常重要，这些资料既能反映该套系统的运行真实情况，也是采取修正措施时的参考。 For a specific water system, the long-term stability of its performance is indispensable, the long-term performance of the RO system's success depends on the normal operation and maintenance, including the test of the whole system, start and shutdown, cleaning and maintenance, membrane surface dirt and scale prevention not only in pre treatment should be considered in design. The appropriate operation is also critical, and record keeping and operating parameters of RO daily report is very important, these data can reflect the real situation of the operating system, but also to take corrective measures as reference. 二、反渗透设备进水与环境要求 Two.

The maximum amount of drainage is 1.5T/H. 设备所在地，应设有照明设施，以便操作。 The location of the equipment should be equipped with lighting facilities for operation. 设备所在地，应留有足够的操作空间，以便操作与检修。 Where the equipment is located, sufficient operating space should be left for operation and maintenance. 设备，应避免接触腐蚀性烟尘气。 Equipment should avoid contact with corrosive smoke and dust. 三、设备操作 Three. Equipment operation 开机 Boot 1、检查电器及管路，确保原水箱有水； 1, check the electrical and pipeline, to ensure that the original water tank has water; 2、开启来水电磁阀前水源开关 2. Open water solenoid valve front water source switch 3、打开【冲洗电磁阀/自动】、【原水泵/自动】、【高压泵/自动】、【总电源/ON】。 3. Open [flush solenoid valve / automatic], [original water pump / automatic], high pressure pump / automatic], [total power supply /ON]. 4、系统开始自动运行 4. The system starts to run automatically 关机： Shutdown: 打开 【冲洗电磁阀/手动】，冲洗2分钟。 Open the solenoid valve / manual and rinse for 2 minutes. 打到【总电源/关】 Hit [total power / turn] 打到【冲洗电磁阀/自动】 Hit the solenoid valve / Auto 反渗透膜的手动冲洗： The manual washing of the reverse osmosis membrane: 冲洗：确信原水箱有水并有水补入，打开【冲洗电磁阀/手动】 Rinse: make sure that the original water tank has water and water is filled, open [flush solenoid valve / manual] 旋至【原水泵/手动】【高压泵/手动】 Turn to [raw water pump / manual] [high pressure pump / manual] 冲洗适当时间后旋到【原水泵/停】【高压泵/停】【冲洗电磁阀/停】 Flush appropriate time to turn to [pump / stop] [high pressure pump / stop] [flush solenoid valve / stop] 反渗透阀门的调节： Reverse osmosis valve regulation: 反渗透系统运行的流量和压力有一定的要求，设备要按要求调到适当的状态使反渗透系统稳定运行，只需调整一次，以后保持手动阀门开度不变即可。 Reverse osmosis system has certain requirements for flow and pressure. The equipment should be adjusted to the appropriate state according to the requirements, so that the reverse osmosis system can run stably. It needs to be adjusted once and then keep the opening of the manual valve unchanged. 1、检查电器及管路，确保原水箱有水； 1, check the electrical and pipeline, to ensure that the original water tank has water; 2、 开启来水电磁阀前水源开关 2. Open water solenoid valve front water source switch 3、 全开RO高压泵后球阀、浓水排放阀、关闭回流阀 3. The full open RO high pressure pump ball valve, the concentrated water discharge valve, the closing reflow valve 4、打开【原水泵/手动】、【高压泵/手动】、【总电源/ON】。 4. Open [raw water pump / manual], [high pressure pump / manual], [total power supply /ON]. 5、RO系统开始运行 5, RO system starts to run 6、高压泵前压力开关的调节：高压泵前压力开关主要防止来水压力不够时高压泵仍运行对设备造成损害。将高压泵前压力开关调到0.5kg/cm2，适当关小高压泵后阀门，使高压泵不频繁启动为止。 6, pressure switch adjustment before high pressure pump: high pressure pump before pressure switch to prevent water pressure is not enough, high pressure pump still running to damage the equipment. The pressure switch in front of the high pressure pump is adjusted to 0.5kg/cm2, and the valve is properly closed after the high pressure pump, so that the high pressure pump is not started frequently. 7、调节浓水排放阀（关小）反渗透膜【进水压力】约0.8--1Mpa,浓水流量约为：0.6m3/h,纯水流量约为1.5m3/h。调节回水阀门使浓水流量约为：0.6-1.0m3/h,【进水压力】约为0.8--1Mpa（在排水全部可以使用时，建议关闭回水阀门，有利增加膜的寿命。 7, regulating the heavy water discharge valve (close small) reverse osmosis membrane [inlet pressure] about 0.8--1Mpa, the flow rate of concentrated water is about 0.6m3/h, and the flow rate of pure water is about 1.5m3/h. Adjusting the backwater valve makes the flow of concentrated water approximately 0.6-1.0m3/h, and the inlet pressure is about 0.8--1Mpa. When the drainage is available, it is recommended to close the return valve, which will increase the life of the membrane. 反渗透主系统的自动控制过程： The automatic control process of the main reverse osmosis system: 流程示意： 电钮全部打到自动档时，设备按如下程序执行： Schematic: All button to automatic control equipment, according to the following procedures: 开机时，原水电磁阀、冲洗电磁阀全开，高压泵延时5秒钟后打开,冲洗30秒钟后，冲洗电磁阀关闭，系统进入正常供水状态。 When starting, the raw water solenoid valve and the flush solenoid valve are all opened. After the high-pressure pump is delayed for 5 seconds, it opens and rinse for 30 seconds. Then the electromagnetic valve is flushed, and the system enters the normal water supply state. 当系统接有纯水高位控制（浮球开关）时，水满时系统自动打开冲洗电磁阀、关闭高压泵，低压冲洗20秒后关闭原水泵、进水电磁阀。原水箱有水、纯水箱低位时，自动开启原水泵、高压泵、进水电磁阀制水。 When the system is connected with the pure water high position control (float switch), when the water is full, the system automatically opens and washes the solenoid valve, and closes the high-pressure pump. After 20 seconds of low pressure flushing, the original water pump and the inlet electromagnetic valve are closed. When the original water tank has water and the pure water tank is low, the original water pump, the high pressure pump and the influent electromagnetic valve are automatically opened. 当前处理系统自动冲洗或再生时，高压泵停，进水电磁阀关。 When the current processing system is automatically washed or regenerated, the high pressure pump stops and the influent electromagnetic valve. 四、前处理操作面板说明 Four.

Type of filter material: refined quartz sand 作用：有效地将水中的悬浮物、杂质去除，降低进水浊度。 Effect: effectively remove the suspended matter and impurities in the water to reduce the turbidity of the influent. 操作方法：砂滤器的管阀布置如图2所示。 Operation method: the pipe valve arrangement of the sand filter is shown in Figure 2. （1）运行 (1) operation 正常启动时，首先打开进水阀A1、正洗排水阀A5，进水流量控制在1.0T/H，运行3-5分钟后逐渐打开出水阀A2，关闭正洗排水阀A5，此时砂滤器进入正常工作。 When starting normally, first open the inlet valve A1 and the normal drain valve A5, and the inlet flow rate is controlled at 1.0T/H. After running for 3-5 minutes, the outlet valve A2 will be opened gradually, and the positive drain valve A5 will be closed. At this time, the sand filter will enter normal operation. （2）反洗 (2) backwash 随着纯水机运行时间的增加，截留的污物逐渐增多，水流阻力变大，此时要进行反洗，以恢复砂滤器过滤能力。先开启反洗排水阀A4和反洗进水阀A3，反洗流量控制在 With the increase of the running time of the pure water machine, the remaining dirt increases gradually and the flow resistance becomes larger. At this time, the reverse washing is needed to restore the filtration capacity of the sand filter. First open the backwash drain valve A4 and the backwash inlet valve A3, the backwash flow control |
