      多介質過濾器濾料板結成塊怎么處理?

      多介質過濾器具有進水、出水、反洗進水、反洗排水、正洗排水的控制功能,并設有壓縮空氣輔助反沖洗接口。開啟原水進水閥和出水閥,并調節閥門至合適的開度后,原水即從上部進入過濾器,自上而下通過過濾層,即可得到合格的清澈水。多介質過濾器是截留廢水中所含大顆粒懸浮物雜質,保護后續系統的安全運行。
      The multi-media filter has the control functions of water inlet, outlet, backwash water inlet, backwash drainage and forward washing drainage, and is equipped with compressed air auxiliary backwash interface. After opening the raw water inlet valve and outlet valve, and adjusting the valve to the appropriate opening, the raw water enters the filter from the upper part and passes through the filter layer from top to bottom, and then qualified clear water can be obtained. The multi-media filter is to retain the large particles of suspended solids in the wastewater to protect the safe operation of the follow-up system.
      多介質過濾器中裝填優質石英砂濾料。石英砂濾料具有截留雜質能力強,雜質穿透深,產水能力大,且具有足夠的機械強度、化學穩定性能好、對人體無害等優點。當運行一段時間后,需要進行正沖洗和反沖洗,將被截留的污物從排水口排出過濾器體外,使濾料保持良好的過濾能力。期間使用壓縮空氣輔助反沖洗,可成倍提高反沖洗之效果。多介質過濾器廣泛應用于工業給水、工業循環用水及村鎮給水處理。其中的石英砂濾料用于直接過濾水中的懸浮物,降低水中懸浮物含量。
      The multi-media filter is filled with high-quality quartz sand filter material. Quartz sand filter material has the advantages of strong ability to retain impurities, deep penetration of impurities, large water production capacity, sufficient mechanical strength, good chemical stability and harmless to human body. After running for a period of time, it is necessary to carry out positive flushing and backwashing to discharge the intercepted dirt from the drainage outlet out of the filter body, so as to keep the filter material with good filtration capacity. During this period, the effect of backwashing can be improved by using compressed air to assist backwashing. Multi media filter is widely used in industrial water supply, industrial circulating water and rural water supply treatment. The quartz sand filter material is used to directly filter the suspended solids in water and reduce the content of suspended solids in water.

      在實際運行中也經常見到過濾器濾料板結的情況,濾料板結結塊主要原因有反洗不徹底、原水水質變化等造成濾料中積累了污泥、油泥或微生物及其排泄物,并與之粘結成塊。消除方法:
      In the actual operation, it is often seen that the filter material is caking. The main reasons for the agglomeration of filter material are incomplete backwashing and the change of raw water quality, resulting in the accumulation of sludge, oil sludge or microorganisms and their excreta in the filter material, which are bound to form blocks. Elimination method:
      (1)加強反洗。強度+時間+壓縮空氣擦洗,針對輕度結塊。
      (1) Strengthen backwashing. Intensity + time + compressed air scrubbing, for mild caking.
      (2)卸出濾料人工清洗。
      (2) The filter material is discharged and cleaned manually.
      (3)堿洗。針對油泥結塊,把NaOH或Na2CO3溶液注入濾池靜泡或進行循環沖洗。
      (3) Alkaline washing. For sludge caking, NaOH or Na2CO3 solution is injected into the filter for static bubble or circulating flushing.
      (4)酸洗。針對濾料上的重金屬沉淀,一般使用鹽酸,注意設備防腐(加緩沖劑)和濾料對鹽酸的穩定性。
      (4) Pickling. For heavy metal precipitation on filter media, hydrochloric acid is generally used. Pay attention to equipment corrosion protection (add buffer) and the stability of filter material to hydrochloric acid.
      (5)氯清洗。針對微生物和有機物生長而致的結塊。投加漂白粉和次氯酸鈉,使水中活性氯達到40~50mg/L,通過濾層,待排水中有氯臭味時,停止排水并靜泡1~2d,殺死有關微生物后,再反洗。為提高清洗效果,上述方法可幾種結合使用。
      (5) Chlorine cleaning. Caking caused by the growth of microorganisms and organic matter. Add bleaching powder and sodium hypochlorite to make the active chlorine in water reach 40-50 mg / L. after passing through the filter layer, when there is chlorine odor in the drainage, stop drainage and soak for 1-2 D. after killing the relevant microorganisms, backwash. In order to improve the cleaning effect, the above methods can be used in combination.
