    石英砂過濾器在運行的時候需要注意什么?
    來源:http://m.gdxinmeihua.com 發布時間:2021-09-24

    石英砂過濾器是以石英砂為過濾介質,在一定壓力下通過一定厚度的顆粒狀或非顆粒狀石英砂過濾高濁度水,截留和去除懸浮物.在本文中,我們就來談談石英砂過濾器在運行的時候需要注意什么?
    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?
    石英砂過濾器運行過程中的注意事項如下:
    Precautions during operation of quartz sand filter are as follows:
    濾速:石英砂濾料的濾速不宜過慢。由于過濾速度太慢,單位過濾面積的處理水量會變小。為了達到一定的水量,必然要增加過濾面積,也需要增加投資。但濾速過快不僅會增加水頭損失,而且會縮短過濾周期,降低出水質量。因此,石英砂濾池的濾速一般為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.

    反沖洗:反沖洗用于去除石英砂濾池濾層中的污泥,從而恢復濾料的過濾能力。為了清洗污泥,一定要有一定的反洗速度和時間。這與濾料的大小、相對密度、膨脹率和水溫有關。石英砂反洗強度為15L/(M2·s),反洗時濾層膨脹率為25%~50%,反洗時間為5~6min。只有反洗效果好,砂濾才能運行良好。
    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.
    水流均勻性:無論是作業還是反沖洗,都要求各斷面水流均勻分布。要使水流均勻,排水系統要好。只有水流的均勻性才能使過濾效果好。
    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.
    以上就是對山東多介質過濾器廠家對于運行中注意事項的介紹。由于過濾速度、反沖洗和水流均勻性是影響石英砂過濾器運行的主要因素,所以在使用石英砂過濾器時一定要注意這些。
    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.
