Abstract

The invention discloses an ultraviolet catalytic oxidation wastewater treatment process, belongs to the technical field of environmental protection, and provides a novel ultraviolet catalytic oxidation wastewater treatment process for solving the problems of unreasonable coagulation agent type selection, low ultraviolet utilization rate and the like. The process combines traditional sewage treatment with ultraviolet catalytic oxidation treatment of wastewater. Compared with the prior art, the treatment process disclosed by the invention has the beneficial effects that the treatment system disclosed by the invention realizes the application of a full-wave band ultraviolet catalytic oxidation technology in practical engineering, and a feasible process which is small in drug dosage, high in ultraviolet light utilization rate, free of an oxidant and stable in operation is provided for wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to water treatment technology, in particular to the field of a novel ultraviolet catalytic oxidation wastewater treatment process. Background technique [0002] In recent years, with the rapid development of pharmaceutical, petrochemical, printing and dyeing, chemical industry, membrane technology and other industries, wastewater containing various refractory organic substances has impacted the urban sewage treatment system, causing a serious burden on the urban sewage treatment system. Most of these high-concentration wastewater contains toxic and refractory organic pollutants such as polycyclic aromatic hydrocarbons, halogenated hydrocarbons, heterocyclic compounds, organic pesticides, heavy metal complexes, etc. Great impact on the environment and human health and safety. Due to the complexity of this type of wastewater, most of the complex pollutants cannot be use...
