    多介质过滤器具有进水、出水、反洗进水、反洗排水、正洗排水的控制功能,并设有压缩空气辅助反冲洗接口。开启原水进水阀和出水阀,并调节阀门至合适的开度后,原水即从上部进入过滤器,自上而下通过过滤层,即可得到合格的清澈水。多介质过滤器是截留废水中所含大颗粒悬浮物杂质,保护后续系统的安全运行。
    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.
    多介质过滤器中装填优质石英砂滤料。石英砂滤料具有截留杂质能力强,杂质穿透深,产水能力大,且具有足够的机械强度、化学稳定性能好、对人体无害等优点。当运行一段时间后,需要进行正冲洗和反冲洗,将被截留的污物从排水口排出过滤器体外,使滤料保持良好的过滤能力。期间使用压缩空气辅助反冲洗,可成倍提高反冲洗之效果。多介质过滤器广泛应用于工业给水、工业循环用水及村镇给水处理。其中的石英砂滤料用于直接过滤水中的悬浮物,降低水中悬浮物含量。
    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.

    在实际运行中也经常见到过滤器滤料板结的情况,滤料板结结块主要原因有反洗不彻底、原水水质变化等造成滤料中积累了污泥、油泥或微生物及其排泄物,并与之粘结成块。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)加强反洗。强度+时间+压缩空气擦洗,针对轻度结块。
    (1) Strengthen backwashing. Intensity + time + compressed air scrubbing, for mild caking.
    (2)卸出滤料人工清洗。
    (2) The filter material is discharged and cleaned manually.
    (3)碱洗。针对油泥结块,把NaOH或Na2CO3溶液注入滤池静泡或进行循环冲洗。
    (3) Alkaline washing. For sludge caking, NaOH or Na2CO3 solution is injected into the filter for static bubble or circulating flushing.
    (4)酸洗。针对滤料上的重金属沉淀,一般使用盐酸,注意真人对赌网址 防腐(加缓冲剂)和滤料对盐酸的稳定性。
    (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。针对微生物和有机物生长而致的结块。投加漂白粉和次氯酸钠,使水中活性氯达到40~50mg/L,通过滤层,待排水中有氯臭味时,停止排水并静泡1~2d,杀死有关微生物后,再反洗。为提高清洗效果,上述方法可几种结合使用。
    (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.
