Abstract

The present invention relates to the field of waste water treatment, and specifically relates to a multi-stage ozone reaction tower technology for injecting ozone into an ejector; the specific composition includes: a regulating tank, a lifting pump, a water distributor, an anaerobic reaction tower, and a biogas collection cover; The jet device enters the ozone multi-stage ozone reaction tower technology. The reaction tower disclosed by the invention utilizes the jet flow technology to circulate jet wastewater and ozone, greatly increasing the contact time and contact area between wastewater and ozone, and improving the utilization rate of ozone; the invention also provides a The hydrophobic ozone decomposition catalyst has high ozone decomposition efficiency, good moisture resistance, and the decomposition efficiency is not affected by ambient humidity, and can be used to decompose ozone under different humidity environments.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a multi-stage ozone reaction tower technology for injecting ozone into an ejector. Background technique [0002] Ozone is an unstable and easily decomposed strong oxidant. Using ozone to treat wastewater is a very effective wastewater treatment technology. [0003] 201821943116.9 discloses an ozone oxidation reactor, including a mixer, a gas phase balance tube, a tower reactor and an ultra-fine bubble distributor in the inner and lower parts thereof. The ultra-fine bubble distributor includes a gas cavity connected to the gas inlet and a The gas-liquid channel in the cavity, the gas-liquid channel is a pipeline passing through the gas cavity, and the side wall of the pipeline has a gas hole that communicates with the gas cavity. At the bottom, the outlet of the circulating liquid is connected to the gas-liquid channel through the wall of the tower reactor through the liquid ...
