Described photocatalytic-bioreactor for sewage treatment is characterized in that: described fibrous packing is fixedly filler or floating stuffing.
Described photocatalytic-bioreactor for sewage treatment is characterized in that: described fixedly filler is soft cellulose filler, vertical elastic filler or comprehensive filler; Described floating stuffing is suspension ball filler or many cavitys foam plastics square filler.
The invention has the beneficial effects as follows:
1, the present invention is the synergy of photochemical catalytic oxidation and biological treatment, according to the difference of sewage character, can adopt different operation processing modes.Simultaneously, must carry out suitable mud according to the requirement of system and reflux, the present invention has also considered inner from return-flow system, with usefulness and the treatment effect that guarantees effective active sludge.
2, sewage treatment process of the present invention and corresponding treatment facility thereof can be adapted to the high density and the sewage of low concentration of high density or difficult degradation; And the processing of the production of lower concentration and high density or the dirty waste water of living; Big as far as possible reduces investment outlay, and reduces running cost, reduces and takes up an area of.
3, the treatment effect of treatment process of the present invention is stable, and reliable, effluent quality can reach the primary standard or the higher standard requirement of discharging standards; The sludge quantity that produces is few, has settling property preferably, is easy to handle.
4, compare with other treatment facility or structures through method and apparatus of the present invention, technical process is short, and treatment effect obviously improves 30%～60%, and working cost reduces by 21%～38%.For the sewage that is difficult to degrade of general aspects, after the synergy through photochemical catalysis and biological treatment, the clearance of entire equipment or technology can reach more than 90%.Treatment facility can with the combination of multiple treatment process, operation scheme is flexible, saves the investment of engineering, reduces floor space.
