The specific embodiment
Embodiment 1:
The efficient air water of a kind of as shown in Figure 1 to Figure 3 microcoacervation is cleaned the filter tank, form by four unit, filter tank 1 of arranging side by side, the quantity of unit, filter tank is specifically selected by the operating mode of needs, each unit, filter tank is equipped with independent intake chamber 2, filtering technique system 3, filtering layer purging system 4 and collecting system 5, a public cover air purging system 6, one cover water purging system 7, it is the 8 cover water inlet systems 9 of unifying that one cover water outlet is collected, air purging system 6 is arranged at water purging system 7 tops, air purging system 6 comprises the gas distribution equipment 10 that is distributed in 1 filtering layer bottom, unit, four filter tanks, intake valve 11, air inlet pipe 12, intake valve 11 is set on the air inlet pipe 12 and connects four gas distribution equipment 10, pore 19 evenly is set on the gas distribution equipment 10.
Water inlet system 9 comprises water inlet pipe 13, distributing channel 14, regulating weir 15, overflow pipe 16, little flocculation tank 17 and mixer 18, described water inlet pipe 13 feeds little flocculation tank 17, mixer 18 is arranged in little flocculation tank 17, little flocculation tank 17 is communicated with distributing channel 14, regulating weir 15 and overflow pipe 16 are set in the distributing channel 14, and overflow pipe 16 is communicated with intake chamber 2.
The handling process of former water is: former water flows into little flocculation tank 17 through water inlet pipe 13, add trace P AC regulate particulate matter surface in the former water electrically, stir through mixer 18, make the extremely even attitude of particulate matter flocculation in the former water, do not become cotton-shaped separating out again, enter distributing channel 14 after the stirring, regulate the intake chamber 2 that flow velocity enters each unit, filter tank 1 by regulating weir 15, overflow pipe 16 in the distributing channel 14 can be when flow velocity exceeds standard be directly imported former water each intake chamber 2, former water flows into each unit, filter tank 1 by intake chamber 2, filtering technique system 3 by unit, filter tank 1 finishes filtration, enters collecting system 5 separately, is converged by each collecting system 5 and finishes filtration to going out water collection system 8.The efficient air water of microcoacervation provided by the present invention is cleaned the filter tank and was added trace P AC at former water before water inlet pipe enters little flocculation tank, can choose the kind and the dosage of flocculant according to the difference that former water treatment requires, after mixing, mixer produces the uniform flco of particle difference, do not precipitate and separate out, the particle that the easier filtration of filtrate is flocculated and uses technology succinctly quick, maintains easily, the equipment cycle of operation is longer, long service life.
When the efficient air water scouring filter tank cycle of operation of microcoacervation reaches, or the filtering layer degree of congestion is when reaching the loss of flood peak of setting, backwash just must be carried out in the filter tank, close water inlet pipe 13 during backwash, open filtering layer purging system 4, make the filter material surface of the water washing and filtering process system 3 of filtering layer purging system 4, carry out gas flushing then, open intake valve 11, air enters each gas distribution equipment 10 through air inlet pipe 12, by pore 19 ejections that evenly are provided with on the gas distribution equipment 10, the impurity of filtering technique system 3 filter material surfaces is cleaned and suspend in water, the purging system 7 of fetching boiling water when gas flushing is stablized carries out further water flushing to filtering technique system 3 filtrates, adopts big resistance distribution this moment, slight drag water distribution technology is carried out, close intake valve 11 earlier after flushing finishes and stop gas flushing, the water flushing continues, by the water of water purging system 7 and filtering layer purging system 4 will band impurity water towards finishing flushing to going out water collection system 8.The efficient air water of microcoacervation provided by the present invention is cleaned the filter tank and the filter tank is being carried out comprised in the flushing process that gas flushing, air water flushing and water washed for three steps, and adopts big resistance distribution, and the mode of slight drag water distribution is cleaned fast, the convenient great amount of cost of saving.
