A kind of water treatment system containing membrane module the most according to claim 2, it is characterised in that: a diameter of 12 ~ 18mm of described immobilized microorganism ball (17).
A kind of water treatment system containing membrane module the most according to claim 1, it is characterised in that: described magnetizing mediums (15) is metallic nickel.
A kind of water treatment system containing membrane module 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 treatment system containing membrane module the most according to claim 4, it is characterised in that: a diameter of 3 ~ 5mm of described magnetizing mediums (15).
A kind of water treatment system containing membrane module the most according to claim 1, its using method is:
The first step, open container (10), make immobilized microorganism ball (17) be flowed in described a kind of water treatment system containing membrane module；
Second step, open magnetic field generator (11) and aerator (13), make described a kind of water treatment system containing membrane module internal generation magnetic field, and then make immobilized microorganism ball (17) be in suspended state in described a kind of water treatment system containing membrane module；
3rd step, opening conduits valve, sewage is flowed into described a kind of water treatment system containing membrane module from water inlet (1)；
4th step, sewage are discharged after the membrane cisterna (6) in described a kind of water treatment system containing membrane module filters；Immobilized microorganism ball (17) is not provided with in the membrane cisterna (6) in magnetic field around being flowed into after using a period of time in described a kind of water treatment system containing membrane module, membrane cisterna (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).
