介质滤波器,也被称为机械过滤器(有一个人将呼吁石英砂过滤器媒体过滤器,因为石英砂颗粒大小是不同的,2 - 3种规格),机械过滤器,别名,实际上是相同的滤波器,在水处理过程中,是一种更常用的机械过滤设备,因为过滤材料低,环境保护、过滤效果的优点是好的,由此得到的石英砂过滤器在水处理中得到了充分的应用。
　　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.
　　为什么多媒体过滤器会产生反效果?，我们从多媒体过滤器的作用开始，它主要用于过滤和拦截水中的悬浮物、沉积物、有机物和其他杂质。过滤的原理主要是被石英砂困住，所以经过一段时间的多媒体过滤后，沙子之间的缝隙中有很多小颗粒，如泥浆、有机物等杂质。如果不进行反洗,过滤槽的拦截泥沙等杂质可以累积,如果影响源性水,和水压力减少,过滤流量减少,不仅浪费宝贵的能源(电力、水泵功率)和污水水质没有达到标准,所以多介质过滤器使用反洗一段时间后必须进行。
　　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.

　　多媒体过滤器有两种反冲洗方式，一种是气水反冲洗，另一种是水反冲洗。
　　There are two kinds of backwashing methods for multimedia filter, one is air water backwashing, the other is water backwashing.
　　空气水反洗:使用气泡和石英砂过滤材料之间的摩擦,而且是用石英砂过滤材料的粒子和粒子之间的摩擦,这是使用石英砂过滤材料和水相冲摩擦,四个互动,限度地增加了反拨效应,所以水洗后的石英砂过滤材料可以正常使用。优点是:反冲洗时间短，耗水量少。所以山东多介质过滤厂家的反冲洗方法是:苏打水反冲洗
　　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
