Integrated reaction device for ozone and activated carbon

Abstract

The invention discloses an integrated reaction device for ozone and activated carbon. The integrated reaction device comprises an inner cylinder, an outer cylinder and a middle cylinder, wherein the inner cylinder and the outer cylinder are coaxially arranged, and the middle cylinder is arranged between the inner cylinder and the outer cylinder; a catalyst packing layer for reacting with ozone is arranged in the inner cylinder, an activated carbon packing layer is arranged in the middle cylinder, and an ozone gas guide pipe assembly used for guiding ozone into the inner cylinder and a water guide pipe assembly are arranged on the outer cylinder. According to the integrated reaction device in the technical scheme, through internal structure integration, all the reaction areas share the same wall, the effluent is connected through water passing holes, connecting pipelines of all reaction areas are reduced, the occupied area is reduced, and the capital construction investment cost is saved. Meanwhile, through the secondary ozone catalytic reaction of the inner cylinder, the purification speed and the purification effect of wastewater are greatly improved, and the product performance is improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an integrated reaction device for ozone and activated carbon. Background technique [0002] Wastewater or drinking water advanced treatment technology is to adopt appropriate treatment methods to remove trace organic pollutants or precursors of disinfection by-products that cannot be effectively removed by conventional treatment processes, so as to improve and ensure water quality safety. The ozone-activated carbon treatment process has become one of the mainstream processes for advanced treatment due to its unique efficiency in removing pollution. [0003] The ozone-activated carbon method is to add ozone before the activated carbon pool, and carry out the ozone contact oxidation reaction in the ozone contact reaction pool. Dosing ozone before activated carbon filtration can oxidize and decompose some organic matter into H2O and CO2, thereby reducing the organic load of acti...

Problems solved by technology

[0004] However, in the normal operation, the layout of each reaction device is scattered, and the occupied area cannot be effectively used, resulting in a large occupied area, cumbersome connecting pipelines, and high infrastructure investment. At the same time, the application of ozone catalytic reaction is not ideal, and effective ozone decomposition cannot be carried out well. organic matter in water
