    石英砂过滤器在运行的时候需要注意什么?
    来源:http://www.jnlzsb.com 发布时间:2021-09-24

    石英砂过滤器是以石英砂为过滤介质,在一定压力下通过一定厚度的颗粒状或非颗粒状石英砂过滤高浊度水,截留和去除悬浮物.在本文中,我们就来谈谈石英砂过滤器在运行的时候需要注意什么?
    Quartz sand filter uses quartz sand as the filter medium to filter high turbidity water through granular or non granular quartz sand of a certain thickness under a certain pressure to intercept and remove suspended solids. In this paper, let's talk about what we need to pay attention to when the quartz sand filter is running?
    石英砂过滤器运行过程中的注意事项如下:
    Precautions during operation of quartz sand filter are as follows:
    滤速:石英砂滤料的滤速不宜过慢。由于过滤速度太慢,单位过滤面积的处理水量会变小。为了达到一定的水量,必然要增加过滤面积,也需要增加投资。但滤速过快不仅会增加水头损失,而且会缩短过滤周期,降低出水质量。因此,石英砂滤池的滤速一般为10-12m/h。
    Filtration rate: the filtration rate of quartz sand filter material should not be too slow. Because the filtration speed is too slow, the treated water per unit filtration area will become smaller. In order to achieve a certain amount of water, it is necessary to increase the filtering area and investment. However, too fast filtration speed will not only increase the head loss, but also shorten the filtration cycle and reduce the effluent quality. Therefore, the filtration rate of quartz sand filter is generally 10-12m / h.

    反冲洗:反冲洗用于去除石英砂滤池滤层中的污泥,从而恢复滤料的过滤能力。为了清洗污泥,一定要有一定的反洗速度和时间。这与滤料的大小、相对密度、膨胀率和水温有关。石英砂反洗强度为15L/(M2·s),反洗时滤层膨胀率为25%~50%,反洗时间为5~6min。只有反洗效果好,砂滤才能运行良好。
    Backwashing: backwashing is used to remove the sludge in the filter layer of quartz sand filter, so as to restore the filtration capacity of filter material. In order to clean the sludge, there must be a certain backwashing speed and time. This is related to the size, relative density, expansion rate and water temperature of the filter material. The backwashing strength of quartz sand is 15L / (M2 · s), the expansion rate of filter layer during backwashing is 25% ~ 50%, and the backwashing time is 5 ~ 6min. Only with good backwashing effect can sand filtration run well.
    水流均匀性:无论是作业还是反冲洗,都要求各断面水流均匀分布。要使水流均匀,排水系统要好。只有水流的均匀性才能使过滤效果好。
    Water flow uniformity: whether it is operation or backwashing, the water flow at each section shall be evenly distributed. To make the water flow uniform, the drainage system is better. Only the uniformity of water flow can make the filtration effect good.
    以上就是对山东多介质过滤器厂家对于运行中注意事项的介绍。由于过滤速度、反冲洗和水流均匀性是影响石英砂过滤器运行的主要因素,所以在使用石英砂过滤器时一定要注意这些。
    The above is an introduction to the precautions for operation of Shandong multi-media filter manufacturers. As the filtration speed, backwashing and water flow uniformity are the main factors affecting the operation of quartz sand filter, these must be paid attention to when using quartz sand filter.
