Ionized water is cleaned by ultrasonic three times, each 10min, then the dry 15min in 37 DEG C of baking ovens, the metallic support that obtains that treated；
(3) apatite layer is generated, the metallic support that step (2) are obtained immerses in configured calcium phosphorus saturated solution, is soaked respectively
Bubble 6h, 12h are stood in 37 DEG C for 24 hours, and deposition obtains apatite layer, drying at room temperature.
9. wastewater treatment composite biological agent according to claim 8, it is characterised in that: the mixed bacteria liquid instills phosphorus ash
Method in stone are as follows:
(1) bacterium solution step is carried, instills mixed bacteria liquid dropwise at a slow speed in the metal support surface with apatite layer of acquisition, is guaranteed
Every drop is all completely immersed in coating, drying at room temperature；
(2) dried metallic support is again dipped into calcium phosphorus saturated solution, generates new apatite layer, is repeated after dry
Bacterium solution is added dropwise, this process circulation obtains multilayer more than twice and carries bacterium solution apatite layer.
