To second compartment.It is moved in circles using such, the sludge yield of system can be reduced, reach the mesh of sludge reduction
's.
The present invention works in this way：
At normal temperatures and pressures, organic wastewater is pre-processed through certain, such as：Oil separation grit chamber or air supporting or regulating reservoir etc., specifically
Depending on waste water quality condition, bion pulling flow type electrocatalysis oxidation apparatus of the present invention is entered by water inlet pipe, waste water is through anode
Enter the electrocatalytic oxidation processing so as to continue second segment communicating pipe from the bottom of adjacent next pole room, until entering end
It holds in the last one anode chamber.Hydraulic detention time is 0.5 ~ 1h in entire treatment unit for waste water device.For anti-locking system it is long when
Between some in pole plate corrosion caused by when running or waste water have sticking substances and be adhered on pole plate to reduce pole plate operation
Efficiency, the present apparatus is provided with timing pole, pole can be automatically switched to down after device continuous operation 10min, original so as to make
Anode becomes cathode, and original cathode becomes anode, under the action of electric current, pollutant on pole plate etc. then can Automatic-falling extremely
