    多介质过滤器在原水处理中的必要性
    来源:http://www.jnlzsb.com 发布时间:2019-04-09

    原水预处理,在水行业也叫给水预处理。在水处理中,深度处理系统,对进水往往有一定的水质要求。而为了延长系统的周期和使用期限,防止系统的损坏,一般尽可能地使进水水质提高。原水只有经过适当的预处理后,方能满足后道制水设备系统对进水的水质要求。所以根据原水中悬浮颗粒、碳酸盐硬度、有机物含量、游离氯等含量的不同,采取不同的预处理是十分有必要的。
    Raw water pretreatment is also called feed water pretreatment in water industry. In water treatment, advanced treatment system often has certain water quality requirements for influent. In order to prolong the period and service life of the system and prevent the damage of the system, the quality of the influent water is generally improved as far as possible. Only after proper pretreatment can the raw water meet the water quality requirements of the back-channel water-making equipment system. Therefore, according to the different contents of suspended particles, carbonate hardness, organic matter content and free chlorine in raw water, it is necessary to adopt different pretreatment methods.
    无论是直接采用离子交换系统或者先用电渗析法(EDI),再加上反渗透的系统,普通的自来水、地下水或工业用水往往都不能够满足离子交换树脂或反渗透膜对玷污物质的进水要求。原水只有经过适当的预处理后,方能满足后道制水制备系统对进水的水质要求。
    Whether directly using ion exchange system or electrodialysis (EDI) first, coupled with reverse osmosis system, ordinary tap water, groundwater or industrial water often can not meet the requirements of ion exchange resin or reverse osmosis membrane for fouling materials. Only after proper pretreatment can raw water meet the water quality requirements of the back-channel water preparation system.
    常用原水预处理方法:
    Commonly used raw water pretreatment methods:
    通过在原水中投加高分子物质(絮凝剂),使水体中细小而松散的絮粒变的粗大而密实,便于快速沉淀。
    By adding macromolecule substance (flocculant) in raw water, the fine and loose flocs in water become coarse and dense, which is convenient for rapid precipitation.
    然后就用到了多介质过滤器,一般过滤器内装有大小不同、种类不同的精制滤料,从上到下、由小到大依次排列,能去除水体中的悬浮物、泥沙、粘土、腐殖物等,使出水浊度达到理想效果。常用的多介质过滤器填料为石英砂。
    Then a multi-media filter is used. Generally, there are different sizes and types of refined filters in the filters. They are arranged from top to bottom and from small to large, which can remove suspended matter, sediment, clay, humus and so on in the water body, and make the turbidity of the effluent reach the ideal effect. Quartz sand is commonly used as filler for multi-media filter.
