Advanced wastewater treatment system by aid of ozone and microwave ultraviolet light oxidation

Abstract

The invention relates to an advanced wastewater treatment system by aid of ozone and microwave ultraviolet light oxidation, and relates to an organic wastewater treatment device. The technical scheme includes that the advanced wastewater treatment system comprises an air compressor, a gas storage tank, a freezer dryer, an oxygenerator, an ozone generator and a dissolved gas pump which are successively connected, wherein two inlets and an outlet are arranged on the dissolved gas pump, the ozone generator is connected with one of the inlets of the dissolved gas pump, the other inlet of the dissolved gas pump is connected with an intermediate water tank, the outlet of the dissolved gas pump is connected with a microwave ultraviolet light device, the rear end of the microwave ultraviolet light device is connected with a circulation water tank, a partition board is arranged in the circulation water tank, water on the upper layer of the partition board is drained out, and water on the lower layer of the partition board returns to the intermediate water tank via a pipe. The advanced wastewater treatment system has higher oxidation efficiency, the service life of equipment is prolonged, the wastewater is sufficiently mixed with ozone, and the efficiency of the advanced wastewater treatment system under actions of microwave ultraviolet light is greatly increased as compared with a system independently using ozone or ultraviolet light technology.

Description

technical field [0001] The invention relates to a treatment device for organic waste water, in particular to a waste water advanced treatment system for oxidation treatment using ozone and microwave ultraviolet light. Background technique [0002] The treatment of refractory organic wastewater is a major technical problem at home and abroad. At present, the effective treatment technology is mainly Advanced Oxidation Technology (Advanced Oxidation Technology). This technology is a group of new technologies developed in the field of environmental protection in the past 20 years. It is defined as any oxidation process involving hydroxyl radicals (??OH, hydroxyl free radical) in the reaction, which belongs to the advanced oxidation process (Advanced Oxidation Process, English abbreviation AOP), also known as advanced oxidation technology. This technology mainly uses strong oxidants with hydroxyl radicals as the core to quickly, non-selectively and thoroughly oxidize various re...

Problems solved by technology

The shortcomings of the existing technology are mainly: low oxidation efficiency; the existing electrode ultraviolet lamp weakens the ultraviolet intensity due to electrode aging and the lamp tube is scrapped due to electrode failure; in the traditional design, the ozone dosing method mostly adopts Venturi jet + static Mixed by the mixer, there are defects such as low dissolution efficiency and large dosage of oxidant; using ozone or ultraviolet technology alone, the efficiency is low
