Container formula ozone catalytic oxidation and bological aerated filter system

The utility model belongs to sewage treatment among the environmental protection engineering especially indicates a container formula ozone catalytic oxidation and bological aerated filter system. Equalizing basin, ozone catalytic tower, middle water tank, bological aerated filter, backwash pond in the box, pump, electric -magnetic flow meter, solenoid valve are controlled by controlling means inthe pipeline, and the backwash pond meets bological aerated filter, ozone catalytic tower input connects the equalizing basin output, water tank in the middle of establishing between ozone catalytic tower and bological aerated filter, and gas -liquid mixture thing that little bubble generator's input connect ozone generator to produce, its output connects the little bubbles circulation pipeline entry in the ozone catalytic tower, and the little bubble generator's of input catalytic tower 2 flow is adjusted to the ozone concentration that controlling means detected according to the catalytic tower 0 appearance, water i
