Connect.
This utility model operationally, first chooses the dominant bacteria of the COD that can degrade and dominant bacteria
Cultivate, a series of process techniques such as preprocessed anaerobic-aerobic advanced oxidation, quartz sand filtration,
Filtering, through MBR activated sludge process and membrane separation technique, the COD produced in waste water after, the water after process reaches
The one-level requirement of national sewage comprehensive emission standard, i.e. CODcr≤100mg/L discharges.
Embodiment the most of the present utility model, for the ordinary skill people of this area
For Yuan, it is possible to understand that can be real to these in the case of without departing from principle of the present utility model and spirit
Executing example to carry out multiple change, revise, replace and modification, scope of the present utility model is by claims
And equivalent limits.
