Catalytic ozonation integrated wastewater treatment device

Abstract

The invention discloses a catalytic ozonation integrated wastewater treatment device. The device comprises a reaction tank which has a water inlet and a water outlet positioned on one side of the water inlet, the height of the water outlet is higher than the height of the water inlet, partitions for enabling water at the water inlet to flow to the water outlet in sequence are arranged in the reaction tank, the partitions are arranged at intervals in the direction from the water inlet to the water outlet so as to form a reaction area for water flow to flow through a space between any two adjacent partitions, and a catalytic bed is installed in each reaction area. According to the invention, the reaction tank is divided into a plurality of reaction areas, so that sewage enters the reaction tank from the water inlet, sequentially passes through reaction chambers and then can be discharged from the water outlet, thereby effectively prolonging the retention time of the sewage in the reaction tank and improving the treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a catalytic ozone oxidation integrated wastewater treatment device. Background technique [0002] With the rapid development of industry, a large amount of waste water is produced while the economy grows, especially the toxic and harmful refractory organic waste water, which pollutes the surface water hugely. Conventional biological methods and other water treatment processes cannot degrade them to meet the corresponding discharge standards. Therefore, advanced oxidation technology is considered to degrade such toxic, harmful and refractory organic substances, reduce their toxicity, and improve their biodegradability. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes an integrated wastewater treatment device for catalytic ozonation. [0004] An integrated wastewater treatme...
