Water in wash pool, which is passed through in microbial deactivation apparatus, to be backwashed, and backwashing time is 3-5 minutes, back washing strength 7-
11L/(s·m2), to rinse out the ferriferous oxide and Mn oxide that adhere on filtrate, and water tank is flowed by overflow pipe
In.
9. microbe filter method as claimed in claim 8, it is characterised in that: contain in the backwashing water that the water tank is collected
There are iron-oxidizing bacteria and manganese oxidizing bacteria, water tank is flowed by overflow pipe when the water level of underground water is excessively high in filter column, in underground water
The ferrous iron and bivalent manganese contained provides the environment of life and breeding for the iron-oxidizing bacteria and manganese oxidizing bacteria of water tank；After 3-6 days,
Iron-oxidizing bacteria and manganese oxidizing bacteria can form colloid substance in the water surface of water tank；Periodically this mucilage binding substance is passed through on top cover
The drain hole at end is added in filter column.
