The present invention relates to an electrolytic cell for electrolytic treatment of organic compounds contained in the water quality, in particular, by using a membrane separation type electrolytic cell, the electrolyte and the organic compound wastewater to be treated are separated and secondary pollution does not occur, and as a working electrode Electrolytic separation flow electrolyzer having excellent electrolysis efficiency using platinum / titanium electrode.

In modern society, pollution by industrial and household wastewater is very important due to environmental and ecological problems. In particular, traces of organic compounds present in wastewater are highly toxic to aquatic life, microorganisms and mammals. Among the toxic organic compounds introduced into industrial wastewater, halogenated organic compounds, especially halogenated hydrocarbon compounds, are produced in large quantities industrially, and phenol derivatives, phenol derivatives, have been reported to have strong toxicity to the living body as carcinogens.

In addition, aromatic amines such as m-nitroaniline and benzidine, which are released from petrochemical, pulp, and chemical industries, react rapidly in the blood, converting hemoglobin into methamoglobin, which interferes with oxygen uptake.

In addition, phenol is mostly contained in the wastewater of processes containing aromatic organic compounds, and is mainly generated in the paper industry, petroleum refining process, plastics, and adhesive process. Since aromatic hydrocarbon compounds entering industrial wastewater and household wastewater are difficult to decompose by biological treatment or ozone, many scientists have been working on the treatment of aromatic organic compounds present in such water quality for the past several years.

Several studies known to date have been conducted to change the structure of a compound to convert it into a biodegradable compound, to partially decompose the molecule to reduce toxicity, or to completely decompose the molecule to produce CO ₂ or H ₂ O or other Its purpose is to convert non-toxic minerals.

The treatment methods used to accomplish this purpose include recovery, incineration, adsorption, microbial decomposition, ozone oxidation, chemical, Fenton, and electro-Fenton. In the Fenton method and the electro-Fenton method, the Fe used for the treatment remains in the solution, causing another environmental pollutant.

The purpose of the study for the practical use of the industrial wastewater treatment method is to develop an economical method that is simple to operate, has high treatment efficiency, and has high reliability.

Recently, many researchers have accepted electrochemical decomposition as a very effective method to partially or completely change the structure of molecules by oxidizing or reducing various organic compounds, and to reduce COD in effluent or biological methods. Much research is underway to develop practical methods for the degradation of toxic species that are difficult to degrade.

In order to realize the electrochemical treatment of wastewater, studies on oxidation and reduction of various chemical species introduced into the wastewater have been conducted. Lead electrode, SnO ₂ , Pt, Au, graphite, Ti / Various types of electrochemical cells have been developed using SnO ₂ , Ti / IrO ₂ , flow-through porous electrodes, fludized bed electrodes, rolling tube electrodes, packed bed electrodes and rod electrodes. Much progress has been made in the research.

These electrodes were used for anodic oxidation of various aromatic organic compounds such as aniline, phenol, benzyl alcohol, toluene and chlorophenol. Phenol and benzoquinone derivatives are representative toxic compounds in organic wastewater, and many studies have been conducted on oxidative decomposition using various types of electrolyzers and lead oxide, SnO ₂ and flow-through porous, Pt, Au, and graphite electrodes. .

First, a study on the oxidation of phenol for wastewater treatment in the presence of NaCl is performed. In this study, NaCl forms ClO ^- when phenol is electrolyzed by a flow-through electrolyzer using Ti / SnO ₂ and Ti / IrO ₂ electrodes. It is known to catalyze the decomposition of phenol to CO ₂ . In addition, electrochemical treatment of phenol in lead dioxide packed bed anodes, oxidative decomposition using p-benzoquinone and maleic acid as representative compounds, are being studied.

It is known that isobutanol is oxidized in the flow electrode using Ni electrode, and isobutylic acid is produced. The results of oxidation reaction of methanol, benzyne, benzoquinone, polyamine and organic compounds in wastewater Many are known.

As shown in the above prior arts, the treatment efficiency of organic compounds depends on the properties of the cathode materials used for oxidation rather than the properties of the compounds themselves, so the development of suitable anode materials is essential in the electrolysis of wastewater.

However, the lead oxide, SnO ₂ , Ti / SnO ₂ may cause secondary contamination of the product during electrolysis because the electrode itself contains contaminants. In addition, Pt and Au electrodes have good efficiency, but are not economically suitable because they are expensive precious metals, and graphite and rod electrodes have no secondary pollution and are stable, but have poor electrolysis efficiency. Fluidized bed electrode, rolling tube electrode, packed bed electrode has a relatively high electrolysis efficiency, but the manufacturing cost and management is difficult.

Therefore, in order to increase the electrochemical treatment efficiency, an electrode having high current efficiency should be used, and in order to solve the problem of mass transfer caused by the treatment of a very thin solution, the surface area of the anode and the compact electrolytic cell are required.

The flow tank type electrolyzer, which is known to be the most efficient among the electrolyzers used for the electrochemical treatment of industrial wastewater, is known to satisfy these characteristics, but the flow tank electrolyzer used in various studies is designed to flow together with the electrolyte. Since the secondary product is generated by the reaction between the electrolyte and the reaction solution during the electrolysis process, it is difficult to identify the intermediate or final product produced. In most cases, the anode material is made of metal or alloy oxide so that the pH of the solution to be treated can be reduced. Therefore, there is a problem that causes secondary metal contamination by elution.

In the electrochemical decomposition of aromatic organic compounds, phenol is widely used as a representative compound, and the final product of phenol anodic oxidation is CO ₂ . As intermediate products of this reaction, p-benzoquinone and aliphatic organic acids such as muconic acid, fumalic acid, maleic acid, succinic acid, and formic acid are produced.The conversion reaction to p-benzoquinone, which is the first reaction step, is known to proceed rapidly. have. Decomposition of aliphatic organic acid by ring-breaking of P-benzoquinone is a rate-limiting step of this decomposition reaction. Especially, in the electrochemical decomposition of phenol, there is a problem of deterioration of surface activity due to the polymerization reaction at the anode surface.

The present invention has been made to solve the above problems, the organic compounds contained in the water quality by the electrochemical method of decomposition, and using a membrane separation electrolyzer to separate the electrolyte and the organic compound waste water to be treated to secondary pollution This does not occur, and the object of the present invention is to provide a membrane separation flow electrolyzer using a platinum / titanium working electrode having improved electrolysis efficiency using a platinum / titanium electrode as a working electrode.
