Novel device for treating industrial wastewater organic matters

Abstract

The invention discloses a novel device for treating industrial wastewater organic matters. The device consists of an ozone generator, an ozone buffer tank, a hydrogen peroxide storage tank, a hydrogen peroxide pump, a reactor, a tail gas treatment device, an air inlet, a liquid inlet, an air exhaust hole, a water inlet and a water outlet, wherein the ozone generator is connected with the ozone buffer tank; the ozone buffer tank is connected with the reactor through the air inlet; the hydrogen peroxide storage tank is connected with the hydrogen peroxide pump; the hydrogen peroxide pump is connected with the reactor through the liquid inlet; the water inlet is arranged at the lower end of the reactor; the air inlet and the liquid inlet are arranged at the lower end of the reactor; a catalyst layer is arranged at the lower part of the reactor, and the tail gas treatment device is arranged at the upper part of the reactor; the air exhaust hole is formed in the lower part of the tail gas treatment device; an upper cover is arranged at the lower end of the air exhaust hole; aeration heads are arranged around the back part of the air inlet at the bottom part of the reactor; the reactor is provided with three water outlets.

Description

technical field [0001] The invention relates to the field of environmental protection sewage treatment, in particular to a novel device for treating organic matter in industrial wastewater. Background technique [0002] At present, in wastewater treatment projects, there are often many refractory substances in wastewater, such as nitrobenzene and other anthraquinones, which are difficult to oxidize by ordinary oxidation methods, and the cost of related new advanced oxidation methods is high. In the case that ordinary treatment methods are difficult to degrade COD in wastewater, the invention-creation (according to the provisions of Article 2, Paragraph 1 of the Patent Law: the invention-creation referred to in this law refers to inventions, inventions and designs. Here I use the invention-creation It is a matter of personal habits, there is no mistake!) Apply the existing chemical oxidation method to the refractory high-concentration chemical wastewater, use hydrogen peroxid...
