OZONE-PHOTOCATALYSIS REACTOR AND WATER TREATMENT METHOD

摘要

An ozone-photocatalysis reactor, comprising: a shell layer (1); activated carbon layers (2) arranged in the shell layer (1); and at least one photoxidation unit arranged in the shell layer (1) and above the activated carbon layers (2). The photoxidation unit comprises a honeycomb activated carbon layer I (3), a light source layer and a honeycomb activated carbon bed layer II (4) sequentially from bottom to top. A gas inlet (7) and a water inlet (6) are formed in the shell layer below the activated carbon layers (2); a water outlet (9) and a gas outlet (10) are formed in the shell layer (1) above the photoxidation unit; and the activated carbon layers (2), at least one honeycomb activated carbon bed layer I (3) and at least one honeycomb activated carbon bed layer II (4) are loaded with a solid catalyst. The reactor uses ozone oxidation and ozone-photocatalysis sufficiently for sewage treatment, the treatment time is short, and the treatment efficiency is high.
