反渗透纯净水设备介绍
Introduction to reverse osmosis purified water equipment
反渗透设备应用膜分离技术，能有效地去除水中的带电离子、无机物、胶体微粒、细菌及有机物质等，是高纯水制备、苦咸水脱盐和废水处理工艺中的最佳设备。
The reverse osmosis equipment applies membrane separation technology,
which can effectively remove charged ions, inorganic substances,
colloidal particles, bacteria and organic substances in water. It is the
best equipment in high-purity water preparation, brackish water
desalination and wastewater treatment processes.
1、设备系统构成
1. Equipment system composition
反渗透纯净水处理系统一般包括预处理系统、反渗透装置、后处理系统、清洗系统和电气控制系统等。
Reverse osmosis purified water treatment system generally includes
pretreatment system, reverse osmosis device, post-treatment system,
cleaning system and electrical control system.
预处理系统一般包括原水泵、加药装置、石英砂过滤器、活性炭过滤器、精密过滤器等。其主要作用是降低原水的污染指数和余氯等其他杂质，达到反渗透的进水要求。
Pretreatment system generally includes raw water pump, dosing device,
quartz sand filter, active carbon filter, precision filter, etc. Its
main function is to reduce the pollution index of raw water and other
impurities such as residual chlorine, so as to meet the inflow
requirements of reverse osmosis.
反渗透装置主要包括多级高压泵、反渗透膜元件、膜壳（压力容器）、支架等组成。其主要作用是去除水中的杂质，使出水满足使用要求。
The reverse osmosis device mainly consists of multi-stage high-pressure
pump, reverse osmosis membrane element, membrane shell (pressure
vessel), support, etc. Its main function is to remove impurities in the
water and make the effluent meet the use requirements.
后处理系统是在反渗透不能满足出水要求定网站建设 伺服液位仪 防撞墙模具 唐山护栏 钢纤维 天津除甲醛 保定铝型材的情况下增加的配置。主要包括阴床、阳床、混床、杀菌、超滤等其中的一种或者多种设备。
The post-treatment system is added when the reverse osmosis cannot meet
the effluent requirements. It mainly includes one or more equipment such
as anion bed, cation bed, mixed bed, sterilization, ultrafiltration,
etc.
清洗系统主要有清洗水箱、清洗水泵、精密过滤器组成。当反渗透系统受到污染出水指标不能满足要求时，需要对反渗透进行清洗使之恢复功效。
The cleaning system is mainly composed of cleaning water tank, cleaning
water pump and precision filter. When the RO system is polluted and the
effluent index cannot meet the requirements, it is necessary to clean
the RO system to restore its efficiency.
