Technologyoverview

Thistechnology is a new type operative technology of advanced oxidation undernormal temperature and normal pressure, of which Biotechina’s proprietarycatalyst can efficiently decompose ozone into hydroxyl free radicals（·OH） that further decompose organic macromoleculesin sewage into small molecules, and then the small molecules are furtheroxidized into carbon dioxide and water. While reducing COD concentration in thesewage, sewage B/C is simultaneously improved.

Biotechina,through reasonable design of reactor structure and ozone adding manner, hasgreatly improved the reaction efficiency and the ozone utilization rate,reduced ozone adding ratio, and thus brought down the operating consumptions.

Technicaladvantages

Ø  Hydroxyl free radicalsreaction with high oxidation efficiency and no selectivity

Ø  Simultaneouslyachieving the targets of removing COD and improving B/C

Ø  Excellentcompatibility with other treatment processes such as biochemical processes

Ø  Adopting Biotechina’sproprietary high-efficiency series of catalysts

Ø  Adopting Biotechina’sproprietary ozone catalytic oxidation reactor, of which structure is reasonable,ozone utilization rate is high and the reaction.is efficient.

Catalyst

Catalystof ozone catalytic oxidation, with composite metallic compounds as its main reactivecomponents, is a series of heterogeneous catalysts independently developed andproduced by Biotechina for treating different types of sewages. The catalyst hassuch characteristics as unique formula, strong catalytic activity, long servicelife, low cost, environmental friendliness and strong adaptability.

Applicationfields

Applicableto the upgrading and reconstructing of municipal sewage plants and industrialsewage plants.

Oftenbeing used in conjunction with biochemical processes to improve sewage B/C anddegrade COD.
