Integrated ozone catalytic oxidation tower

Abstract

The invention belongs to the technical field of wastewater treatment and in particular relates to an integrated ozone catalytic oxidation tower. The oxidation tower comprises a tower body, spiral tubes and two catalyst traps, wherein the spiral tubes are arranged in the tower body; the catalyst traps are arranged in the tower body at an interval along the height direction of the tower body; the two catalyst traps are used for partitioning the inner cavity of the tower body into a rotating bed reaction zone, a fixed bed reaction zone and a water storage zone from bottom to top; the fixed bed reaction zone is used for filling a granular oxidation catalyst; the rotating bed reaction zone is equipped with a power paddle and a rotating paddle in coaxial linkage; the spiral tubes are distributedin the rotating bed reaction zone, the fixed bed reaction zone and the water storage zone; water inlets of the spiral tubes communicate with an ozone inlet and a sewage inlet; the water inlets are located in the water storage area; and water outlets of the spiral tubes are located in the rotating bed reaction area. The oxidation tower is capable of reducing requirements on power support, reducingoperation and maintenance cost and simplifying operation, in addition, greatly improving the biodegradability and organic matter removal rates of treated sewage, and reducing the difficulty of subsequent retreatment.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to an integrated ozone catalytic oxidation tower. Background technique [0002] The per capita share of water resources in China is very low, and with population growth, regional economic development, and accelerated industrialization and urbanization, the demand for urban water continues to grow, which will make the problem of insufficient water supply and water shortage increasingly serious. Industrial production requires a lot of water, and at the same time, it will also produce a large amount of industrial sewage. If it cannot be effectively treated, the problem of water shortage will be further aggravated. [0003] Industrial sewage generally has high chemical oxygen demand (COD), dark color, strong odor and poor biodegradability, which makes industrial sewage difficult to treat. The biodegradability of treated sewage is still low, which increases the difficulty of...
