Microelectrolysis-fenton oxidizing reaction device

Abstract

The invention belongs to the technical field of sewage treatment, and in particular relates to a microelectrolysis-fenton oxidizing reaction device. The oxidizing reaction device comprises a wastewater supply device, and a hollow-out reactor made of anti-corrosive materials; a barrel body of the reactor is internally divided into a fenton oxidizing reaction area, a microelectrolysis reaction area and a flocculoreaction area from bottom to top; the microelectrolysis reaction area is full of iron-carbon fillers. The device also comprises a draining device arranged at the upper side of the reactor. The draining device is convenient for draining the treated wastewater to the outside of the oxidizing reaction device. The microelectrolysis-fenton oxidizing reaction device has the advantages that the microelectrolysis technology and the fenton oxidizing technology are integrated, so that the effective space of the reactor can be furthest utilized, i.e.,, the electrochemical reaction and the oxidization-reduction reaction can be carried out synchronously within the effective space of every independent unit device, therefore, the wastewater treatment process can be greatly simplified, the impact of various factors on wastewater treatment operation can be reduced, the purification performance of unit equipment in wastewater treatment can be improved, and as a result, an ideal treatment effect can be obtained.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a micro-electrolysis-Fenton oxidation reaction device. Background technique [0002] Micro-electrolysis and Fenton (Fenton) oxidation technology are two different wastewater treatment technologies, which are often used separately or simultaneously in the design of wastewater treatment processes, and can achieve better treatment results. In the prior art, the common practice when using micro-electrolysis and Fenton (Fenton) oxidation technology at the same time is to connect the micro-electrolysis reactor and the Fenton oxidation reaction device successively in series, in order to achieve better treatment effect, thereby for the follow-up biochemical process Provide good pretreatment conditions. However, this design method of series use needs to be equipped with two different unit processing equipment, that is, it is necessary to connect the independent micro...

Problems solved by technology

However, this design method of series use needs to be equipped with two different unit processing equipment, that is, it is necessary to connect the independent micro-electrolysis reactor and Fenton oxidation reaction device according to the set process, and configure a series of auxiliary pipelines and facilities, this simple superimposed connection method not only requires large construction investment, high operating costs, lengthy and complicated treatment process, but also makes it difficult for the micro-electrolysis reactor and Fenton oxidation reaction device to be in the optimal operating condition at the same time, so it is also difficult to obtain ideal processing efficiency
