              多介質過濾器應用原理介紹

              多介質過濾器在水處理過程中,過濾一般指的是石英砂,無煙煤濾料層攔截水中的懸浮雜質,使水澄清的過程。用于過濾的多孔材料,石英砂過濾材料是更常見的。與粒狀過濾材料,粉末和各種纖維。常用與石英砂、無煙煤活性炭、磁鐵礦、石榴石、多孔陶瓷和塑料球等等。
              In the water treatment process of multi-media filter, filtration generally refers to the process of quartz sand and anthracite filter material layer intercepting suspended impurities in water and making water clear. Quartz sand is the most common porous material for filtration. With granular filter materials, powders and various fibers. Commonly used with quartz sand, anthracite activated carbon, magnetite, garnet, porous ceramics and plastic balls and so on.
              過濾器 內多介質濾料為優質均粒礫石、石英砂、磁鐵礦、無煙煤等濾料,這些濾料根據其比重和粒徑的大小在過濾器罐體內科學有序的分布,如比重小而粒徑稍大的無煙煤放在濾床的更上層,比重適中和粒徑小的石英砂放在濾床的中層,比重大和粒徑大的礫石放在濾床的更下層。這樣的配比保證了過濾器在進行反洗的時候不會產生亂層現象,從而保證了濾料的截留能力。

              filter The multi-media filter media in the filter tank are high-quality homogeneous gravel, quartz sand, magnetite, anthracite and other filter media. These filter media are scientifically and orderly distributed in the filter tank according to their specific gravity and particle size. For example, anthracite with small specific gravity and slightly larger particle size is placed in the top layer of the filter bed, quartz sand with moderate specific gravity and small particle size is placed in the middle layer of the filter bed, and gravel with large specific gravity and particle size is placed in the bottom layer of the filter bed The bottom. This ratio ensures that the filter will not produce disordered layer when backwashing, so as to ensure the interception capacity of filter material.
              多介質過濾器(又稱機械過濾器)是以成層狀的無煙煤、砂、細碎的石榴石或其他材料為床層,一個典型的多介質過濾器。
              Multi media filter (also known as mechanical filter) is a typical multi-media filter with layered anthracite, sand, fine garnet or other materials as the bed.
              床的頂層由更輕和更粗品級的材料組成,而更重和更細品級的材料放在床的低部。其原理為按深度過濾--水中較大的顆粒在頂層被去除,較小的顆粒在過濾器介質的較深處被去除。從而使水質達到粗過濾后的標準。
              The top layer of the bed consists of the lightest and coarsest grade materials, while the heaviest and finest grade materials are placed in the lower part of the bed. The principle is deep filtration - the larger particles in the water are removed at the top layer, and the smaller particles are removed at the deeper part of the filter medium. So that the water quality can reach the standard after coarse filtration.
              設備是壓力式的,其原理是當原水自上而下通過濾料時,水中懸浮物由于吸附和機械阻流作用被濾層表面截留下來;當水流進濾層中間時,由于濾料層中的砂粒排列的更緊密,使水中微粒有更多的機會與砂粒碰撞,于是水中凝絮物、懸浮物和砂粒表面相互粘附,水中雜質截留在濾料層中,從而得到澄清的水質。經過濾后的出水懸浮物可在5毫克/升以下。
              The principle of the equipment is that when the raw water passes through the filter material from top to bottom, the suspended solids in the water will be intercepted by the surface of the filter layer due to adsorption and mechanical resistance; When the water flows into the middle of the filter layer, because the sand particles in the filter layer are arranged more closely, the particles in the water have more chances to collide with the sand particles, so the flocs, suspended solids and sand particles in the water adhere to each other, and the impurities in the water are trapped in the filter layer, so as to obtain the clarified water quality. The suspended solids in the filtered effluent can be less than 5 mg / L.
              多介質過濾器是由幾種過濾介質組合添裝,在一定的壓力下使濁度較高的水通過過濾器,有效去除懸浮物雜質使水澄清的過程,常用的濾料有石英砂,無煙煤,錳砂等,主要是用于水質深度凈化的預處理,可根據工藝要求填加不同的濾料。
              The multi-media filter is a process of adding several filter media to make the water with high turbidity pass through the filter under a certain pressure to effectively remove the suspended solids and impurities and make the water clear. The commonly used filter media are quartz sand, anthracite, manganese sand, etc., which are mainly used for the pretreatment of water quality deep purification. Different filter media can be added according to the process requirements.
