Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the implementation of the patent of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the patent of the present invention.

[0025] The principle of the patent of the present invention is as follows: ozone is a strong oxidant, and the hydroxyl radical (OH) produced by its decomposition has a stronger oxidizing ability than ozone molecules, and the reaction is non-selective, and can quickly oxidize and decompose sewage a large number of organic pollutants.

[0026] Ozone oxidation technology is the use of hydroxyl radicals (OH) generated by ozone to decompose organic pollutants in water. It is an efficient sewage treatment technology that can quickly oxidize and decompose a large number of organic pollutants in sewage. In recent years, it has become an industrial sewage t...

Abstract

The invention relates to an ozone advanced treatment method based on metal ions for industrial wastewater. The method mainly comprises the steps of preparing a metal ion solution containing Ti<4+>, Fe<2+>, Mn<2+> and Zr<4+>, performing treatment in an ozone device, and performing treatment in a device containing a KI solution for certain residence time; and the method is characterized in that themetal ion solution is used as a catalyst, ozone is used as an oxidant for advanced treatment, and the KI solution is used as a tail-gas treatment solution. The method provided by the invention has thecharacteristics that the COD removal rate in treatment effects achieves 80% or more, the operation is simple and convenient, and the costs are lower.

Description

technical field [0001] The invention belongs to the technical field of advanced water treatment, and in particular relates to a metal ion-based ozone advanced treatment method for industrial wastewater. Background technique [0002] The rational use of modern water resources is an important content in the implementation of my country's sustainable development strategy. The characteristics of large water consumption and large sewage discharge in chemical industry parks are no longer suitable for the needs of water resource utilization in the development of modern society. [0003] There are many types of pollutants in wastewater. According to the different hazards caused by wastewater to environmental pollution, it can be roughly divided into solid pollutants, aerobic pollutants, organic pollutants, oil pollutants, toxic pollutants, biological pollutants, acid-base pollutants, and nutritional pollutants. , sensory pollutants and thermal pollution. Solid pollutants exist in...
