Description

TECHNICAL FIELD [0001] The present invention relates to a wastewater treatment apparatus,

The present invention relates to a wastewater treatment apparatus with improved performance including an electron oxidation station, and more particularly, to a wastewater treatment apparatus capable of measuring a point where a treatment efficiency is lowered in a treatment process in an electron oxidation station, To an improved wastewater treatment apparatus.

Generally, a corona discharge method is known as a method or structure for generating anions at atmospheric pressure. The corona discharge method is a structure that induces generation of a corona discharge between each electrode by applying a high voltage to the electrode by the corresponding polarity.

The generated corona discharge can be classified into an anode corona and a cathode corona depending on the voltage applied to the electrode by polarity. The characteristics of the double anodic corona are more likely to expand spatially than the cathode corona, but the cathode corona method in which a large amount of free electrons and radicals are generated is widely used in the field of industrial devices.

In addition, a method for generating free electrons and anions is classified into a pulse power system, an ac power system, and a DC power system depending on the type of a power source for applying power to each electrode. The structure of the conventional ozone generator and the anion oxygen generator using the pulse power source is composed of a pin-plate structure composed of a discharge pin and a ground. The positive electrode takes the form of a plate and the negative electrode takes the form of a pin. When pulsed power is applied to each electrode, a corona discharge is formed, and ozone or anion oxygen is generated. However, the conventional power generating apparatus has a complicated structure for applying power to each of a plurality of discharge pins and a plurality of discharge pins, and thus there is a problem that workability is low when components are replaced.

In addition, when the electrons generated from the electron generator are supplied to the wastewater treatment plant, the efficiency of the wastewater treatment can be greatly increased. However, since the conventional wastewater treatment technologies introduce such electrons and ions into a certain portion of the wastewater treatment plant, The supply amount can be controlled and the electrons and ions can not be variably supplied to various wastewaters of various kinds.

Hereinafter, the configuration and operation of an embodiment of the present invention will be described in detail with reference to the drawings.

Fig. 1 shows a wastewater treatment apparatus including the electron generating apparatus 200. Fig.

The wastewater treatment apparatus includes a flow rate adjusting tank 210 in which wastewater is stored; A pump for discharging the wastewater stored in the flow rate adjusting tank 210 to the outside and transferring the wastewater through the wastewater transfer line; A biological reaction tank (220) for reacting the wastewater supplied from the flow rate control tank (210) with microorganisms to separate effluent water and sludge; An effluent water tank 230 for temporarily storing effluent water discharged from the bioreactor; A sludge storage tank (240) for temporarily storing the sludge discharged from the bioreactor; And an electron generator (200) including an electron generator (201) for discharging the gas to activate it as electrons and ions and supply it to the wastewater under processing.

Since the supply amount of the wastewater is different depending on time, the wastewater treatment device is required to be supplied with a constant flow rate. Therefore, the wastewater is temporarily stored in the flow rate adjustment tank 210, It is possible to supply the water at a constant flow rate to enable smooth operation of the wastewater treatment apparatus.

The bioreactor 220 is a means for injecting microorganisms into the wastewater supplied from the flow rate adjusting tank 210 to precipitate solid components, and it is possible to convert contaminants or suspended matter in the wastewater into microparticles through solidification, . In addition, the bioreactor 210 may be a diaphragm-type reaction vessel 221 or a separation membrane-type reaction vessel 222. Blowers 223 and 224 may be installed in the diverging or separating membrane, Can be supplied.

The discharged water tank 230 is a means for temporarily storing the discharged water discharged from the bioreactor 220. When the discharged water temporarily stored is not precipitated, the discharged solid water can be further precipitated. When the discharged water reaches the predetermined water level, Respectively.

The sludge storage tank 240 may temporarily recycle the solid (sludge) discharged from the bioreactor 220 to the flow regulating tank, the bioreactor, or the discharged water tank by further separating the liquid contained in the sludge .

The electron oxidation station 200 includes the electron generator 201 and is connected to the flow rate control tank 210, the bioreactor 220, the discharge water tank 230, and the sludge storage tank 240, Is a means for supplying generated electrons. Conventional electronic wastewater treatment system increases the treatment efficiency of wastewater by injecting the electrons generated from the electron generator to a certain point, but it is applied to various wastewater and treatment plant because the injection point is different according to the type and treatment method of each wastewater. It is impossible. However, in the present invention, after the supply of the electrons generated by the electron generator 201 is installed in each treatment tank, the supply of the electrons generated in the flow rate adjusting tank 210, the bioreactor 220, the effluent water tank 230 and the sludge storage tank 240 Since the treatment efficiency is measured and electrons are supplied according to each treatment efficiency, the treatment efficiency can be maximized, and it is possible to flexibly cope with the change of the wastewater and the change of the treatment method.

Also, since the electron oxidation station 200 can supply the electrons from the minimum amount to the maximum amount according to the treatment efficiency of each treatment tank, it is possible to supply an appropriate amount of electrons according to the condition of each treatment tank. At this time, the treatment efficiency can be measured through the chemical oxygen demand (COD), biological oxygen demand (BOD), hydrogen ion concentration (pH), suspended solids (SS), total nitrogen (TN) and total phosphorus Therefore, it is preferable to measure this and supply the appropriate electrons to each treatment tank.

Further, it is preferable that the electron oxidation station 200 divides the amount of electrons generated from the minimum amount to the maximum amount during the supply of the electrons into 10 to 500 steps, more preferably 50 to 150, most preferably 100 . When subdividing into less than 10 steps, it is difficult to supply precise amount of electrons because the difference in electron generation amount between each step becomes large. In the case of subdividing into more than 500 steps, it takes a long time to move between each step, It is difficult to supply.

In addition, a comprehensive control panel 202 is installed in the electron oxidation station 200 to measure the contamination condition of each treatment tank, and to supply an appropriate amount of the generated electrons to each treatment tank according to each contamination situation.
