The invention discloses a
catalytic ozonation fluidized bed reactor for efficiently removing CODcr in
wastewater and belongs to the field of
sewage treatment equipment. The reactor comprises a
fluidized bed reactor body, a
solid-liquid
separation system, an
ozone oxidation
system, a powdered catalytic oxidant addition
system and a powdered catalytic oxidant recycling
system. The reactor has the outstanding capacity of removing difficultly biodegraded organic pollutants in
wastewater in the industries such as
coal chemical industry, steel, biological
pharmacy and printing and
dyeing, can serve as a pretreatment system of a membrane
filtration system and can also be used for industries and regions executing the high COD
emission standard. The COFR technology has the advantages of low
investment cost, simple structure and simplicity and convenience in operation, the COD removal rate is high, secondary
pollution is avoided, the modular combination mode is convenient to design and implement, the COFR reactor can be combined with other
water treatment methods, the problems that the
sewage treatment in the
coal chemical industry,
pharmacy, printing and
dyeing and other related industries does not reach the standard and the concentrated water in
nanofiltration reverse osmosis and other processes cannot be treated can be effectively solved, and the reactor is an effective and practical novel technology and is widely applied and popularized.
