Abstract

The invention relates to an integral solar energy photoelectricity water-treatment device comprising an electrode couple or an three-dimensional electrode as well as an electrolytic bath, a storage battery, solar energy battery components and corresponding controllers and an ultraviolet lamp, wherein the electrode couple or the three-dimensional electrode is loaded with photocatalytic materials; the ultraviolet lamp is used for illuminating a photoelectrode; the solar energy battery components convert the received solar light energy to electric energy which is then transmitted and stored in the storage battery so as to supply power for the ultraviolet lamp and/or the electrode couple intermittently or continuously. The invention integrates an optical chemical oxidation process and an electric chemical oxidation process which both generate enhancement and synergetic effects for improving the water treatment efficiency, or the functions of the optical chemical oxidation process and the electric chemical oxidation process can be independently exerted to realize water purification; the invention has the advantages of simple structure, low manufacturing cost, safe and simple operation, easy realization of automation and safe maintenance, driving the entire water treatment process by wholly or partly utilizing the electric energy converted from the solar energy, solving the problem of high dependence on energy sources in a photoelectrocatalytic water treatment process and being capable of not depending on the traditional power grid in service.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an integrated solar photoelectric water treatment device. Background technique [0002] With the development and improvement of wastewater treatment technology, organic wastewater with simple components and good biodegradability has been effectively controlled. Biological method is currently the most economical and effective method to eliminate organic pollutants in domestic and industrial wastewater. However, with the rapid development of petrochemical, pharmaceutical, pesticide and fuel industries, the number and types of refractory organic compounds in industrial wastewater are increasing day by day, especially containing high concentrations of aromatic compounds, such as phenolic (three) substances, etc. It is highly toxic and difficult to remove directly by general biodegradation methods. On the other hand, the country's limit standards for pollutant discharge are getting hi...
