A kind of water cleaning systems the most according to claim 2, it is characterised in that: a diameter of 12 ~ 15mm of described immobilized microorganism ball (17).
A kind of water cleaning systems the most according to claim 1, it is characterised in that: described magnetizing mediums (15) is metallic nickel.
A kind of water cleaning systems the most according to claim 4, it is characterised in that: described metallic nickel is the metallic nickel after Passivation Treatment.
A kind of water cleaning systems the most according to claim 4, it is characterised in that: a diameter of 4 ~ 5mm of described magnetizing mediums (15).
7., according to a kind of water cleaning systems described in claim 1-6, its method of operating is:
The first step, open container (10), make immobilized microorganism ball (17) be flowed in described a kind of water cleaning systems;
Second step, open magnetic field generator (11) and aerator (13), make that described a kind of water cleaning systems is internal produces magnetic field, and then make immobilized microorganism ball (17) be in suspended state in described a kind of water cleaning systems;
3rd step, opening conduits valve, sewage is flowed into described a kind of water cleaning systems from water inlet (1);
4th step, sewage are discharged after the sedimentation basin (6) in described a kind of water cleaning systems precipitates;Immobilized microorganism ball (17) is not provided with in the sedimentation basin (6) in magnetic field around being flowed into after using a period of time in described a kind of water cleaning systems, sedimentation basin (6) bottom is sunk to by the gravity of self, and entering in collection device (14), part immobilized microorganism ball (17) is back in pre-denitration pond (2) by return duct (12).
