              多介質過濾器濾料板結原因分析!
              來源:http://www.mtffz.com 發布時間:2019-09-24

              多介質過濾器是利用一種或幾種過濾介質,在一定的壓力下把濁度較高的水通過一定厚度的粒狀或非粒材料,從而有效的除去懸浮雜質使水澄清的過程,但是我們在使用中會發現會出現濾料板結的現象,今天山東多介質過濾器的小編就給大家分析一下原因,希望對大家有所幫助!
              Multimedia filter is a process of clarifying water by using one or several filter media to remove suspended impurities effectively by passing turbidity water through granular or non-granular materials with a certain thickness under certain pressure. But we will find that there will be the phenomenon of filter material hardening in use. Today, Shandong Multimedia Filter Xiaobian will give you an analysis of the reasons, hoping to help you all!
              1、截留在濾層上表層的污物,如果在一定周期內,不能有效地去除,在隨后的反洗過程中,如果反洗空氣的分布不均勻會導致膨脹高度不均勻,隨著反洗空氣的搓動,搓動量小的地方,濾料表面的油污等雜質不能有效去除,在投入下一正常濾水周期后,局部負荷增大,雜質會從表面沉入內部,球團逐漸增大,并同時向過濾器的填充深度內延伸,直至整個過濾器失效。
              1. If the contamination on the surface of the filter layer can not be removed effectively within a certain period, the uneven distribution of the air in the subsequent backwashing process will lead to uneven expansion height. With the rubbing of the air in the backwashing process, where the rubbing momentum is small, the oil contamination and other impurities on the surface of the filter material can not be removed effectively. After putting into the next normal filtration cycle, the local load will increase, the impurities will sink from the surface into the interior, the pellets will gradually increase, and extend to the filling depth of the filter at the same time, until the whole filter fails.
              備注:實際運行中,反洗空氣不均勻的現象經常出現,主要是由于底部布氣管道的穿孔、局部濾帽的堵塞或損壞或是柵管間距的變形等原因引起。
              Note: In actual operation, uneven backwash air often occurs, mainly due to perforation of bottom gas distribution pipeline, blockage or damage of local filter cap or deformation of grid pipe spacing.

              2、濾層的表面濾料顆粒細小,反沖洗時相互碰撞機會少,動量小,所以不易清洗干凈。附著的砂粒易結成小泥球。當反沖洗結束濾層重新級配時,泥球就進入下層濾料中,隨著泥球的長大不斷向深處移動。
              2. The surface of the filter layer has fine particles, less chance of collision and less momentum when backwashing, so it is not easy to clean. Attached sand particles tend to form small mud balls. When the backwash is finished, the mud ball enters the lower filter material and moves to the depth with the growth of the mud ball.
              3、原水中所包含的油,截留在過濾器內,經反洗并殘余部分,日積月累,是導致過濾器濾料板結的主要因素。何時進行反洗可根據原水的水質特點和出水水質要求,采用限定水頭損失、出水水質或過濾時間等標準來確定。
              3. The oil contained in the raw water, which is intercepted in the filter, washed back and the residual part, accumulated over time, is the main factor leading to the filter material hardening. When to carry out backwashing can be determined according to the water quality characteristics of raw water and the water quality requirements of effluent, using the criteria of limited head loss, effluent quality or filtration time.
