Description

Powder electrodes fix equipment

The present invention relates to a fixing device for fixing a powder electrode in which electro-aggregation is formed, and more particularly, it is formed in a rectangular parallelepiped shape by compressing porous zero-valent iron with a press, and contained in the influent supplied from the outside using the electro-aggregation principle. A powder electrode that aggregates and dissolves contaminants, and an electrode terminal connector for supplying electricity to the powder electrode is inserted and fixed, and an inlet groove is formed at a predetermined interval so that the inflow water passes between the powder electrodes on the lower surface, and the electrode The terminal connector is installed so that it is positioned higher than the powder electrode, and a holder with a treated water discharge groove for discharging the treated water from which pollutants have been removed from the powder electrode is formed on the upper side of the powder electrode fixing device that uniformly treats the influent water and improves water treatment efficiency. It is about.

In general, water treatment technology is classified into physical, chemical, and biological treatments according to treatment methods, and primary treatment refers to physical treatment, and secondary treatment refers to chemical treatment and biological treatment. And the tertiary treatment refers to all of the above physical, chemical, and biological treatments as a highly advanced treatment method.

For each pollutant, natural separated substances are removed by physical treatment, water-soluble pollutants and colloidal particles are removed by chemical and biological treatment, and nitrogen, phosphorus, trace amounts of organic and inorganic substances are removed by biological treatment or advanced treatment such as a separator. do.

For domestic sewage, nitrogen, phosphorus, and organic matter are removed by the activated sludge method by microorganisms, and for industrial wastewater, the pH is adjusted using caustic soda or slaked lime by adding a water-soluble metal salt to the wastewater containing heavy metals. It generates hydroxide, floats or precipitates, and is removed by sludge.

This water treatment method requires a large facility area to secure the treatment time (around 15 hours), and the flexible response is limited when the amount of wastewater is increased or decreased intermittently, and the sludge treatment cost increases when using chemicals to increase the sedimentation efficiency. There is.

Such a water treatment method has been converted from a chemical treatment method to a biological treatment method that can reduce the use of chemicals, but a physicochemical pretreatment process is required for non-degradable wastewater, and a chemical oxidation method using ozone, hydrogen peroxide, etc. has recently been used. .

Compared to general chemical treatment, the method used to increase the oxidizing power is Advanced Oxidation Process (AOP). AOP is an oxidizing treatment of organic substances and hardly decomposable substances that are pollutants in water by generating OH radicals with strong oxidizing power in water. It is an advanced chemical treatment method, and the advanced oxidation methods that have been popularized in Korea are outlined in the Fenton oxidation method, the ozone oxidation method, the photocatalytic oxidation method, and the electron beam oxidation method.

These advanced oxidation methods are very efficient in oxidizing organic substances because they use OH radicals, which have stronger oxidizing power than conventional chemical treatment methods, as an oxidizing agent, but each method has many disadvantages compared to its own performance.

For example, the Fenton oxidation method using chemicals may cause maintenance costs and secondary pollutants due to the use of chemicals, and the ozone oxidation method using ozone requires electricity cost and ozone post-treatment facilities compared to ozone generation efficiency and safety. There is a problem with management risks.

The development of technology that can overcome these problems as much as possible and completely treat organic and hardly decomposable substances is an essential research task for the protection of water resources that are rapidly deteriorating due to rapid industrialization, and the treatment efficiency is excellent and secondary pollutants are generated. There is no concern, and economical wastewater treatment technology that is easy to maintain is required.

Meanwhile, in the electrocoagulation method, when electric current is supplied, metal ions are eluted from the electrode plate, contaminants in wastewater are coagulated and adsorbed, and contaminants are removed by being floated or precipitated by hydrogen and chlorine gas.

The electric coagulation method has a wide range of applications to remove various pollutants such as heavy metals other than organic matter, has a high processing speed, excellent processing efficiency, and has a small installation area and simple process.

However, since the conventional electrocoagulation method simply arranges a plurality of electrodes and passes the treated water, there is a problem that the overall water treatment efficiency is deteriorated.

In order to solve such a problem, the wastewater treatment apparatus using the Korean Patent Registration No. 10-1221565 electrocoagulation adds a certain amount of inorganic coagulant or organic coagulant to the wastewater flowing into the reaction chamber, or a mixture of inorganic coagulant and organic coagulant. Thus, the floc formation was improved to further improve the coagulation rate, but there is a disadvantage in that the sediment cannot be discharged because it is difficult to recycle the sediment due to the introduction of chemicals, and the sediment must be disposed of.

In addition, in the conventional wastewater treatment device using electric coagulation, the efficiency of the electrode deteriorates as the electrode is used, and the efficiency decreases due to the adhesion of hard substances to the anode.In order to use it after cleaning, not only the system has to be stopped, but the facility is changed depending on the degree of water pollution. There is a drawback of getting bigger.

The front and rear surfaces and the upper surface are open, and the powder electrode 110 and the electrode terminal connector 120 are inserted into the inside, and the inlet groove 131 through which the influent water passes between the plurality of powder electrodes 110 on the lower surface is spaced at a predetermined interval. Treated water discharge grooves are formed to be spaced apart, insert grooves 132 into which the multipole rods 121 of the electrode terminal connector 120 are inserted in the longitudinal direction on both sides, and discharge treated water from which contaminants have been removed. The powder electrode fixing device including; a holder 130 in which 133 is formed.
The method of claim 1,
In the holder 130, the central width of the lower surface 130a is narrower than the width of both side surfaces 130b, and the front and rear surfaces of the lower surface 130a are made up of half of the inflow groove 131 so that a plurality of holders 130 are connected. The powder electrode fixing device is provided so that the powder electrode 110 is spaced apart from the powder electrode 110 of the other holder 130 at the same interval.
The method of claim 1,
The powder electrode 110 is stacked and inserted into the holder 130 into which the electrode terminal connector 120 is inserted, and the spacer 140 so that the powder electrode 110 contacts the multi-pole 121 of the electrode terminal connector 120. ) Is inserted into the insertion groove 132 powder electrode fixing device.
The method of claim 1,
The powder electrode 110 is a powder electrode fixing device comprising iron ore, limestone, and coal.
The method of claim 1,
A powder electrode fixing device in which the holder 130 is disposed and coupled to the other holder 130 in a front and rear surface, and a plurality of electrode terminal connecting rods 120 are connected to a bus bar at the top of the plurality of holders 130 to receive electricity. .
The method of claim 1,
The powder electrode fixing device is installed to be detachably sliding from the lower surface (130a) of the holder (130) from both side surfaces (130b).
The method of claim 1,
The length of the multi-pole rod 121 is formed longer than the length of the insertion groove 132 so that the upper end of the multi-pole rod 121 is disposed equal to or higher than the treated water discharge hole 133 of the holder, so that the treated water Powder electrode fixing device discharged to the treated water discharge hole 133 via a rod 121.
