In sewage-treatment plant, the effect of sedimentation tank is mainly mud-water separation, and the method that routine uses is free sedimentation, flocculation sediment, group's precipitation and compression precipitating, but method of each precipitation has respective shortcoming, or the sedimentation time is oversize, or mud-water separation is not thorough, settleability is bad.
Summary of the invention
It is an object of the invention to provide the immobilized microorganism ball and using method thereof being applied in sewage-treatment plant, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: the immobilized microorganism ball being applied in sewage-treatment plant, and including magnetizing mediums and activated sludge, described magnetizing mediums is without magnetic, but can magnetize under the influence of a magnetic field, described activated sludge is rich in microorganism；Described activated sludge is wrapped in magnetizing mediums, is formed spherical.
Preferably, the preparation of the described immobilized microorganism ball being applied in sewage-treatment plant and to reclaim be to be dissolved into by solvent and thick be sufficiently mixed with magnetizing mediums afterwards by will be enriched in the activated sludge of microorganism, then become bead sector-style of going forward side by side to do by Mold Making in mixture；Bead after air-drying again is placed among magnetic field, and under the active force in magnetic field, the bead that the internal bead containing magnetizing mediums does not contains magnetizing mediums with inside separates, and the internal bead containing magnetizing mediums is immobilized microorganism ball；Immobilized microorganism ball is applied in sewage-treatment plant, and by arranging magnetic field generator generation magnetic field around sewage-treatment plant, makes immobilized microorganism ball be in suspended state in sewage-treatment plant；Immobilized microorganism ball is in long-time use, the activated sludge on surface loses activity gradually, the immobilized microorganism ball being not provided with in the sedimentation tank in magnetic field around being flowed into sinks to bottom by the gravity of self and reclaims, finally by the immobilized microorganism ball reclaimed by soaking, rolling, centrifugal mode reclaims magnetizing mediums；Again the magnetizing mediums being recovered to and activated sludge are sufficiently mixed and again make immobilized microorganism ball.
Preferably, a diameter of 1 ~ 5mm of described immobilized microorganism ball.
Preferably, described magnetizing mediums is metallic nickel.
Preferably, described metallic nickel is the metallic nickel after Passivation Treatment.
Preferably, a diameter of 0.3 ~ 2mm of described magnetizing mediums.
The described immobilized microorganism ball being applied in sewage-treatment plant, its using method is:
The first step, sewage-treatment plant arranging magnetic field generator, the sedimentation tank in sewage-treatment plant is not provided with magnetic field generator；
Second step, being placed in sewage-treatment plant by multiple immobilized microorganism balls, under the effect of magnetic field generator, immobilized microorganism ball is in suspended state in sewage-treatment plant；
3rd step, immobilized microorganism ball are in long-time use, the activated sludge on surface loses activity gradually, the immobilized microorganism ball being flowed into sedimentation tank in sewage-treatment plant along with sewage sinks to bottom sedimentation tank by the gravity of self, carries out reclaiming preparing by the immobilized microorganism ball sunk to bottom sedimentation tank again.
Compared with prior art, the invention has the beneficial effects as follows: one, described apply the immobilized microorganism ball preparation in water treatment facilities and the immobilized microorganism ball prepared by recovery method uses immobilized mode can make Microorganism incubation, this mode can not only maintain the activity of microorganism, preferably purify water, and can preferably make mud-water separation, settleability is good；A diameter of 1 ~ 5mm of immobilized microorganism ball, the diameter of immobilized microorganism ball will need bigger magnetic field that immobilized microorganism ball just can be made to suspend because of too big, sewage also will not be difficult to touch the microorganism inside immobilized microorganism ball because the diameter of immobilized microorganism ball is too big, and immobilized microorganism ball also will not be difficult to because diameter is the least prepare and reclaim；Two, immobilized microorganism bag includes magnetizing mediums and activated sludge, magnetizing mediums can make magnetizing mediums magnetize under the effect of externally-applied magnetic field, immobilized microorganism ball is enable to be in suspended state under the influence of a magnetic field, thus may advantageously facilitate the circulation of microorganism and improve microbial activity, can preferably purify water；Immobilized microorganism ball also will not be made to be damaged by the way of magnetic field controls immobilized microorganism ball；Three, immobilized microorganism ball can recycle, one side is due to the bacteria metabolism in immobilized microorganism ball and processes sewage for a long time, cause the microorganism in immobilized microorganism ball slowly old dead, use the mode reclaimed periodically discharge and supplement immobilized microorganism ball, the microorganism in immobilized microorganism ball can be made to be in high activity state all the time；On the other hand in water, flocculence or floating microorganism can be discharged together along with immobilized microorganism ball, and the microorganism of discharge is also used as preparing the raw material of immobilized microorganism ball.
