水處理里面很多過濾器需要進(jìn)行反沖洗的，特別是填料過濾器，通過填料攔截將雜質(zhì)過濾到填料中，如果不及時(shí)進(jìn)行沖洗，會(huì)出現(xiàn)一下情況，
Many filters in the water treatment need to be backwashed, especially the packing filter. Impurities are filtered into the packing through the packing interception. If the filter is not washed in time, there will be a situation,
、出水流量小。
First, the outflow flow is small.
第二、出水水質(zhì)差。
Second, the quality of effluent is poor.
第三、填料會(huì)結(jié)塊，時(shí)間長(zhǎng)了都沖洗不干凈。
Third, the packing will agglomerate, and it will not be cleaned after a long time.
當(dāng)出現(xiàn)第三種情況，必須要進(jìn)行更換濾料。
In case of the third situation, the filter material must be replaced.
下面是因?yàn)殚L(zhǎng)時(shí)間不清洗的石英砂過濾器，石英砂濾料出現(xiàn)情況。嚴(yán)重出現(xiàn)了結(jié)塊的現(xiàn)象。
The following is because the quartz sand filter is not cleaned for a long time, and the quartz sand filter material appears. The phenomenon of caking appeared seriously.
