| 反渗透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。 Reverse osmosis 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。 The pretreatment system generally includes quartz sand filter, activated carbon filter and precision filter. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine to meet the requirements of reverse osmosis. 预处理系统详细分类说明： Detailed classification of pretreatment system: 1、石英砂过滤器 1. Quartz sand filter 石英砂过滤器主要去除水中的悬浮物、胶体、泥沙、粘土、腐植物、颗粒物等杂质。可降低水的浊度，达到水质澄清的目的，保护反渗透膜。 Quartz sand filter mainly removes suspended solids, colloids, silt, clay, rotten plants, particles and other impurities in water. It can reduce the turbidity of water, achieve the purpose of water quality clarification, and protect the reverse osmosis membrane. 2、活性炭过滤器 2. Activated carbon filter 活性炭过滤器主要利用活性炭表面大量的羟基（氢氧基）和羟基等官能团，对各种物质进行化学吸附，去除水中的异味、有机物、胶体、铁及余氯，同时降低水的色度、浊度，减少对反渗透系统的污染。 Activated carbon filter mainly uses a large number of hydroxyl (hydroxyl) and hydroxyl functional groups on the surface of activated carbon to carry out chemical adsorption of various substances, remove the peculiar smell, organic matter, colloid, iron and residual chlorine in water, reduce the color and turbidity of water, and reduce the pollution of reverse osmosis system. 3、软化器 3. Softener 利用离子交换树脂上的钠离子交换水中的钙镁离子，降低水的硬度，同时用软水盐进行离子交换树脂再生。软水盐又名离子交换树脂再生剂。 The sodium ion on the ion exchange resin is used to exchange calcium and magnesium ions in water, so as to reduce the hardness of water. At the same time, soft water salt is used to regenerate the ion exchange resin. Soft water salt is also known as ion exchange resin regenerant. |
