Description
Technical field:
The present invention 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.
The patent No. is 201310465930X, the application for a patent for invention that patent name is the device of microparticle suspension " automation purify liquid waste ", disclose a kind of novel wastewater treatment equipment, it adopts sieving mode from top to bottom, utilize the gravity of water self to filter, and the natural pressure difference utilizing the pressure in filter pipe to be greater than ambient pressure carry out backwash, energy-conserving and environment-protective, structure is simple, with low cost.But there is following shortcoming in the device of this patent: the interior of rotating shaft hollow of this device, only there is a passage, the side that rotating shaft stretches out outside housing is provided with sewage outlet, the side that rotating shaft is positioned at housing is connected with multiple sewage pipe, one end of multiple sewage pipe is all connected with the passage in rotating shaft, the other end is connected with each connecting hole on rotating suction disc respectively, when when rotating suction disc rotates, each connecting hole is relative with each first lead to the hole site respectively, because the pressure in filter pipe is greater than ambient pressure, water in filter pipe just can upwards recoil, drive microparticle suspension through each sewage pipe, interior of rotating shaft passage, each sewage outlet is discharged.Such design, because the pressure in each filter pipe there are differences, just can there are differences with the pressure differential in the external world, when carrying out backwash, the larger filter pipe of pressure differential just can backwash stronger, the less filter pipe of pressure differential just can backwash more weak, thus cause each filter pipe to occur the situation that recoil is uneven, the microparticle suspension that time has been grown in the weak filter pipe of backwash increases, and filter effect just can be affected, and then affects the wastewater treatment efficiency of whole equipment.
