A fluidized bed ozone oxidation tower

Abstract

The invention discloses a fluidized bed type ozone oxidation tower which comprises a tower body, a water outlet tank arranged at the top of the tower body, a reflux tank communicated with the water outlet tank and an ozone device. The bottom of the tower body is provided with sewage inlets; the interior of the tower body is divided into a water flow adjusting area, a fluidized bed filling area, a fluidized bed reaction expansion area and a reaction buffer water outlet area from bottom to top; a water flow adjusting device is arranged in the water flow adjusting area, and the fluidized bed filling area is filled with an ozone catalyst; a reflux water inlet is formed in the water flow adjusting area of the tower body; the water outlet tank is provided with a water draining port, the reflux tank is provided with a reflux water outlet, and the height of the water draining port is larger than that of the reflux water outlet; the water outlet tank is communicated with the reflux tank through two communicating pipes, the height of one communicating pipe is not larger than that of the reflux water outlet, and the height of the other communicating pipe is not smaller than that of the water draining port; the reflux water outlet is communicated with the reflux water inlet through a pipeline provided with a gas-liquid mixing device; the ozone device is connected with the gas-liquid mixing device; the top of the water outlet tank and the top of the reflux tank are sealed, and the top of the water outlet tank is provided with an exhaust pipe.

Description

technical field [0001] The invention relates to a device in the field of waste water treatment; more specifically, it relates to a novel fluidized bed type ozone oxidation tower. Background technique [0002] In recent years, with the rapid development of the national economy, water environment protection is an issue that is widely concerned by the current human society. With the rapid development of my country's national economy, high-concentration organic wastewater poses a threat to my country's precious water resources. However, using existing biological treatment methods, it is difficult to treat organic wastewater with poor biodegradability and relatively large molecular weight, and advanced oxidation processes (Advanced Oxidation Process, referred to as AOPs) can directly mineralize it or increase pollutants through oxidation. At the same time, it also has great advantages in the treatment of trace harmful chemical substances such as environmental hormones. It can com...

AI Technical Summary

Problems solved by technology

In the actual oxidation process, there are problems of low ozone utilization rate and high treatment cost, which seriously limit the application of ozone oxidation method.
