Now let Jinan Lianzhong heat supply equipment factory take you to understand the operation mode of Shandong multi-media filter!

　　多介質過濾器又稱機械過濾器（現(xiàn)在有很人將石英砂過濾器稱呼為多介質過濾器，因為石英砂顆粒大小不同，分2-3種規(guī)格），機械過濾器，別名很多，其實就是相同的過濾器，在水處理工藝中，是更常用的一種機械式過濾設備，因為濾料低廉，，過濾效果好等優(yōu)勢，所以石英砂過濾器得到了在水處理中得到了充分的應用。

　　Multi media filter is also called mechanical filter (now many people call quartz sand filter as multi-media filter, because quartz sand particle size is different, divided into 2-3 specifications). Mechanical filter, with many aliases, is actually the same filter. In water treatment process, it is the most commonly used mechanical filter equipment, because the filter material price is low, environmental protection, filtering effect So quartz sand filter has been fully used in water treatment.

　　多介質過濾器為什么要進行反洗呢？我們從多介質過濾器的作用說起，多介質過濾器主要是過濾與攔截水中的懸浮物，泥沙，有機物等雜質。過濾原理主要是通過石英砂截留來的，所以多介質過濾器工作一段時間后，砂的縫隙間有許多的細小顆粒物，如泥，有機物等雜質等。如果不對其進行反洗，過濾罐體內攔截的泥沙等雜質會越積越多，從而影響了源水的通過性，并使出水壓力變小，過濾流量減少，不但浪費了寶貴的能源（電能，水泵提供動力），而且出水水質不達標，所以，多介質過濾器使用一段時間后必須要進行反洗工作。

　　Why should the multi-media filter be backwashed? First of all, we start from the function of the multi-media filter, which mainly filters and intercepts the impurities such as suspended solids, sediment and organic matters in the water. The filtration principle is mainly intercepted by quartz sand, so after the multi-media filter works for a period of time, there are many fine particles between the gaps of sand, such as mud, organic matter and other impurities. If it is not backwashed, the impurities such as sediment intercepted in the filter tank will accumulate more and more, which will affect the trafficability of the source water, reduce the outlet pressure, reduce the filtration flow, not only waste the precious energy (electricity, power provided by the pump), but also the outlet water quality is not up to the standard. Therefore, the backwashing work must be carried out after the multi-media filter is used for a period of time.

　　多介質過濾器有兩種反洗方式，一種是氣水反洗，另外一種是水反洗。

　　There are two backwashing methods for multi-media filter, one is air-water backwashing, the other is water backwashing.

　　氣水反洗：是利用空氣的氣泡還有石英砂濾料兩者相互摩擦，再者就是利用石英砂濾料的顆粒與顆粒之間的摩擦力，也就是利用石英砂濾料和水相沖的摩擦力，四者相互作用，在的限度上增加了反沖洗的效果，這樣經(jīng)過反水洗后的石英砂濾料就可以進行正常使用。優(yōu)點是：反洗時間較短，耗水量少。所以工泉水處理科技有限公司反洗方法是：汽水反洗

　　Air water backwashing: the air bubble and quartz sand filter material are used to rub against each other. The friction between the particles of quartz sand filter material is also used, that is, the friction between quartz sand filter material and water is used. The interaction of the four increases the backwashing effect to the maximum extent, so that the quartz sand filter material after backwashing can be used normally Use. Advantages: short backwashing time and less water consumption. Therefore, the recommended backwashing method of Gongquan Water Treatment Technology Co., Ltd. is: steam water backwashing
