Description
Technical field:
The utility model relates to a kind of online backflushing formula sewage-treatment plant.
Background technology:
The operation principle of traditional active sand filter is that former water enters filter interior by water inlet pipe, and after water-locator uniform distribution on to adverse current by filter material layer and outer row, it is mainly used in removing microparticle suspension in waste water, and it is used for the process of trade effluent, the pretreatment etc. of desalinization.In processing procedure, former water is filtered, pollutant load in water reduces, in quartz sand filter media, the content of pollutant increases simultaneously, the sand-washing device that the quartz sand filter media of bottom is carried to filter top by the air lift being arranged in filter central authorities under the effect of air compressor machine cleans, filter sand returns filter bed after cleaning, will clean produced pollution beyond the region of objective existence row simultaneously.By sewage, from bottom to top adverse current is by filter material layer with filter sand is risen to the cleaning of top sand-washing device by air lift still there is the higher problem of power consumption, and the device still complex structure of active sand filter, cost of investment is higher.
