Abstract

The invention provides a catalytic ceramic membrane reactor. The reactor comprises a reactor body, wherein a catalytic ceramic membrane assembly, a catalytic energy supply system, an aeration system and a catalyst recovery system are arranged in the reactor body; the catalytic ceramic membrane assembly is arranged in the middle of the reactor body; the catalytic energy supply system is arranged onthe outer side of the catalytic ceramic membrane assembly; the aeration system and the catalyst recovery system are sequentially arranged below the catalytic ceramic membrane assembly; the reactor body is filled with a photocatalyst-containing sol system. The catalytic ceramic membrane reactor can effectively decompose organic matter, control membrane pollution, retain the catalyst, reduce membrane cleaning cost, achieve advanced treatment and improve effluent quality standards.

Description

technical field [0001] The invention relates to a catalytic ceramic membrane reactor, which belongs to the technical field of sewage treatment. Background technique [0002] In today's world, the problems of deteriorating water environment and shortage of water resources are becoming more and more serious. Membrane water treatment technology has become the leading technology of new water treatment technology due to its outstanding advantages of high efficiency, energy saving, good selectivity and wide application. Among them, inorganic ceramic membranes have the characteristics of high temperature resistance, oxidation resistance, and high mechanical strength. However, membrane fouling and high cleaning costs have become bottlenecks that limit the development of ceramic membranes. As a new, green and environmentally friendly water treatment technology, catalytic oxidation has significant advantages in the deep removal of non-degradable and refractory organic matter by bioche...
