    影响多介质过滤器的出水效果的因素有哪些?
    来源:http://www.mjingoma.com 发布时间:2019-05-17

    多介质过滤器主要利用多种过滤介质,在一定的压力下,把浊度较高的水通过滤质,有效的截留除去水中的悬浮物、有机物、胶质颗粒、氯、嗅味及部分重金属离子等,终达到降低水浊度的一种高效过滤设备。不过有用户在使用过程中发现过滤器的出水效果并不是很好,那是什么原因导致了这一现象呢?
    Multimedia filters mainly use a variety of media, under a certain pressure, the turbidity of water through the filter, effectively intercept and remove suspended matter, organic matter, colloid particles, chlorine, odor and some heavy metal ions in the water, and ultimately achieve a high-efficiency filtration equipment to reduce water turbidity. However, some users find that the effluent effect of the filter is not very good in the process of using. What is the reason for this phenomenon?
    1.水流的均匀性
    1. Uniformity of flow
    无论是运行或反洗时,都要求各截面的水流分布均匀。要使水流均匀,主要是排水系统要良好。只有水流的均匀性,才能使过滤效果良好。
    Whether in operation or backwashing, uniform distribution of water flow in each section is required. In order to make the water flow uniform, the drainage system should be good. Only the uniformity of water flow can make the filtering effect good.
    2.滤速
    2. filtration rate
    多介质过滤器的滤速不能过于慢。因为滤速过慢,单位过滤面积的处理水量就小。为了达到一定的出水量,势必要增大过滤面积,也就要增加投资。但如果滤速过快,不仅增加了水头损失,过滤周期也会缩短,并会使出水的质和量下降。滤速一般选择10~12m/h。
    Multimedia filters should not be too slow. Because the filtration speed is too slow, the amount of treated water per unit filtration area is small. In order to achieve a certain amount of effluent, it is necessary to increase the filtering area and investment. But if the filtration speed is too fast, not only the head loss is increased, but also the filtration cycle is shortened, and the quality and quantity of the effluent will be reduced. The filtration rate is usually 10-12 m/h.

    3.反洗
    3. backwash
    反洗是用以除去滤层中的泥渣,以恢复滤料的过滤能力。为了把泥渣冲洗干净,必须要有一定的反洗速度和时间。这与滤料大小及相对密度、膨胀率及水温都有关系。反洗时,滤层的膨胀率为25%~50%,反洗时间5~6min。只有反洗效果好,才能使砂滤器运行良好。
    Backwashing is used to remove the sludge in the filter layer to restore the filtering capacity of the filter material. In order to clean the sludge, it is necessary to have a certain speed and time of backwashing. This is related to the size and relative density of filter media, expansion rate and water temperature. When backwashing, the expansion rate of the filter is 25%-50%, and the backwashing time is 5-6 minutes. Only when the backwashing effect is good can the sand filter run well.
