介質(zhì)濾波器,也被稱為機械過濾器(有一個人將呼吁石英砂過濾器媒體過濾器,因為石英砂顆粒大小是不同的,2 - 3種規(guī)格),機械過濾器,別名,實際上是相同的濾波器,在水處理過程中,是一種更常用的機械過濾設(shè)備,因為過濾材料價格低,環(huán)境保護、過濾效果的優(yōu)點是好的,由此得到的石英砂過濾器在水處理中得到了充分的應(yīng)用。
　　Media filter, also known as mechanical filter (one person will call for quartz sand filter media filter, because quartz sand particle size is different, 2-3 specifications), mechanical filter, alias, is actually the same filter, in the process of water treatment, it is the most commonly used mechanical filter equipment, because the price of filter material is low, the advantages of environmental protection and filtering effect are good The obtained quartz sand filter has been fully used in water treatment.
　　為什么多媒體過濾器會產(chǎn)生反效果?首先，我們從多媒體過濾器的作用開始，它主要用于過濾和攔截水中的懸浮物、沉積物、有機物和其他雜質(zhì)。過濾的原理主要是被石英砂困住，所以經(jīng)過一段時間的多媒體過濾后，沙子之間的縫隙中有很多小顆粒，如泥漿、有機物等雜質(zhì)。如果不進行反洗,過濾槽的攔截泥沙等雜質(zhì)可以累積,如果影響源性水,和水壓力減少,過濾流量減少,不僅浪費寶貴的能源(電力、水泵功率)和污水水質(zhì)沒有達(dá)到標(biāo)準(zhǔn),所以多介質(zhì)過濾器使用反洗一段時間后必須進行。
　　First of all, we start from the role of multimedia filter, which is mainly used to filter and intercept suspended solids, sediments, organics and other impurities in water. The filtering principle is mainly trapped by quartz sand, so after a period of multimedia filtering, there are many small particles in the gap between the sand, such as mud, organic matter and other impurities. If backwashing is not carried out, the impurities such as intercepted sediment in the filter tank can be accumulated. If the source water is affected, and the water pressure is reduced, and the filtration flow is reduced, not only precious energy (power of power and water pump) is wasted, but also the sewage quality is not up to the standard. Therefore, the backwashing of multi-media filter must be carried out after a period of time.

　　多媒體過濾器有兩種反沖洗方式，一種是氣水反沖洗，另一種是水反沖洗。
　　There are two kinds of backwashing methods for multimedia filter, one is air water backwashing, the other is water backwashing.
　　空氣水反洗:使用氣泡和石英砂過濾材料之間的摩擦,而且是用石英砂過濾材料的粒子和粒子之間的摩擦,這是使用石英砂過濾材料和水相沖摩擦,四個互動,限度地增加了反撥效應(yīng),所以水洗后的石英砂過濾材料可以正常使用。優(yōu)點是:反沖洗時間短，耗水量少。所以山東多介質(zhì)過濾廠家推薦的反沖洗方法是:蘇打水反沖洗
　　Air and water backwashing: the friction between bubbles and quartz sand filter material, and the friction between particles of quartz sand filter material, is the friction between quartz sand filter material and water. Four interactions maximize the backwash effect, so the quartz sand filter material after water washing can be used normally. Advantages: short backwashing time and less water consumption. Therefore, the recommended backwashing method of Shandong multi-media filter manufacturer is: soda water backwashing
