Abstract： |
For improving properties of mixed liquid in membrane biologic reactor, membrane pollution developing speed is controlled to stabilize operation of membrane biologic reactor. The invention provides a method that ozone is utilized to treat mixed liquid in membrane biologic reactor effectively to improve properties of mixed liquid thus to control membrane pollution. The partical steps are in following; ozone generator is used to produce ozone, ozone inventory is mot more than 1mg O3/g-ss which is used to do centralized treatment for the mixed liquid in the membrane biologic reactor, or mud circulating pump is used to pump some mixed liquid in said membrane biologic reactor, or mud circulating pump is used to pump some mixed liquid in said membrane biologic reactor into ozone reaction tank to be treated by adding ozone that inventory is more than 100 mg O3/g-ss, then treated mixed liquid is circulated into said membrane biologic reactor to be mixed with original mixed liquid. |
