Description

A Electrolysis / Electroflotation Combined Electrolyzer of counter flow type for sewage and wastewater treatments}

The present invention relates to a counter-flow electrolysis / injury-integrated electrolysis reactor for advanced treatment and sterilization of wastewater, and more specifically, flow between wastewater and wastewater and gas generated during electrolysis. It is an electrolysis reactor for the advanced treatment and sterilization of wastewater and sewage, which increases efficiency in the form of counter flow and can simultaneously perform electrolysis (electrolysis oxidation) and electric flotation in a single device.

Conventional electrolytic reactors for wastewater treatment have been produced and used in a reactor for electrolytic coagulation, a reactor for electrolysis, and a reactor for electrolytic flotation.

When the electrolytic reaction is initiated, oxidation and sterilization of organic matter in wastewater and sewage due to the generation of various oxides are carried out, and fine oxygen gas and hydrogen gas of the negative electrode plate are generated in the positive electrode plate. It is adsorbed by floating materials, surfactants, n-HEX, etc., and can float and remove organic matters.

Conventional reactors manufactured and used in the prior art are designed in a form using only a part of the overall phenomena generated during electrolysis according to the application purpose.

Therefore, the following disadvantages are raised.

Existing reactors manufactured for electrolysis (organic oxidation) emit oxygen and hydrogen gas generated at this time as they are, so there is no use of gas such as sterilization by generated oxygen and floating effect by oxygen or hydrogen. The efficiency of the electric flotation reactors, which induces a large amount of this gas by simply generating a float, is relatively good for oxidizing organic materials by electrolysis using a catalyst material coated with a catalyst material which is relatively easy to generate gas and has low catalytic ability. I didn't lose.

In addition, all the reactors using electrolysis are designed in the same direction (parallel flow) of the flow of gas and liquid, it is not easy to use the gas generated at this time.

In addition, the wastewater treatment process has a problem in that the electrolytic flotation device and the electrolysis (electrolytic oxidation) reactor must be configured and operated independently of each other.

Therefore, in the wastewater and sewage treatment of the electrolysis reactor, a combination of electrolysis and electrolytic flotation is more efficient, and the flow of the wastewater and sewage is also preferably designed as a counter flow.

The purpose of the present invention to solve the above problems is to provide a structure that can be performed simultaneously in a single process by combining electrolysis (electrolytic oxidation) and electrolytic flotation reaction, and also to improve the efficiency of waste water and sewage flow The present invention provides an improved electrolytic reactor in the form of a counter flow.
