Description

Wastewater treatment device with air spray nozzle {Wastewater disposal plant having air spray nozzle}

The present invention relates to a wastewater treatment apparatus in which an air spray nozzle is incorporated, and more particularly, to a wastewater treatment apparatus incorporating an air spray nozzle used in a water-cooled warm / cooler of a wastewater treatment apparatus.

In general, wastewater generated from sewage, livestock wastewater and manure is decomposed by inflow into the wastewater treatment device, and microorganisms are introduced into the aeration chamber to decompose wastewater introduced into the aeration chamber through the wastewater inlet. As it is naturally activated inside the aeration chamber, it decomposes the dirt inside the aeration chamber.

On the other hand, oxygen is supplied to the microorganisms in the aeration chamber to be actively active, the air is supplied to the aeration chamber through the blower and the air supply pipe.

Here, when the temperature in the aeration chamber is 30-40 ° C., the growth of microorganisms and decomposition of dirt are most actively performed.

However, when the air is supplied by operating the blower in the summer when the temperature in the atmosphere is about 30 ° C, the temperature of the air discharged therefrom by frictional heat, etc. according to the operation of the blower was about 74 ° C. Air of the same temperature is further heated while passing through the solar air-heated metal air supply pipe, so when air of 74 ° C. or higher is supplied into the aeration chamber, the temperature of the waste water rises to approximately 42 ° C. or higher to prevent the activity of microorganisms. There was a problem such as slowing down.

In addition, in winter, the cold air supplied into the aeration chamber through the blower and the air supply pipe lowers the temperature of the waste water to an appropriate temperature or less, thereby slowing the activity of the microorganisms, thereby lowering the decomposition power of the waste water.

There has been much research to improve this. For example,

Japanese Laid-Open Patent Publication No. 58-58193 describes a treatment method in a biological treatment tank in which a copper tube is immersed in a cooling water tank and spirally passed through.

In order to clean the waste water distribution in Korea Utility Model Publication No. 86-472, it is necessary to open the cover of the machine to clean the inside of it and develop a defect that does not have good heat exchange effect. The air backwashing device of the wastewater heat exchanger with the built-in air conditioner and the control valve installed in the backflow pipe and the wastewater supply pipe installed in the wastewater supply pipe is described.

The conventional techniques have used a simple physical principle, and there has been a problem in that air supplied to the aeration chamber cannot be supplied to the aeration chamber at an appropriate temperature in a short time.

The present invention for solving the problems as described above is to improve the wastewater treatment apparatus equipped with the name ON, the cooler of the utility model registration application No. 99-15228 (99. 7. 28) the applicant has filed, An object of the present invention is to provide a wastewater treatment apparatus in which an air spray nozzle is provided, which is designed by improving a nozzle in an air passage in a conventional wastewater treatment apparatus, and which can supply air at an appropriate temperature in the aeration chamber even in summer or winter. It is.

Bar is heated to about 45 ℃ while passing through the cooler 15, when the air passes through the air pipe 24 in the heat transfer space 22 of about 80 ° C introduced into the heat transfer space 22 through the water inlet pipe 25 As the water contacts the plurality of air tubes 24, the air temperature in the air tubes 24 is increased.

At this time, the temperature of the water discharged through the heat transfer space 22 to the water outlet pipe 26 is about 72 ℃, the temperature of the air supplied to the aeration chamber 11 through the air pipe 24 is about 47 ℃.

Therefore, the air heated to about 47 ° C. is supplied into the aeration chamber 11 to be mixed with the waste water cooled by the cold weather, and the temperature of the waste water is slightly increased. As described above, the microorganisms actively move inside the aeration chamber 11. It is made to be 30-40 ℃ suitable for activity.

Therefore, water-cooled depending on the season and temperature. Since the temperature of the air supplied to the aeration chamber 11 is properly adjusted by passing water having an appropriate temperature through the cooler 15, a temperature of about 30-40 ° C. suitable for microorganisms to actuate the temperature inside the aeration chamber 11. It can be kept constant.

Here, the air tube 24 may be formed in a straight shape as shown in FIG. 5, but may be provided in a curved shape to maximize the contact area with water passing through the heat transfer space.

The present invention as described above by supplying water of about 18 ℃ in the summer to cool the air of about 80 ℃ about 30 ℃, by supplying water of about 80 ℃ in winter to heat the air of about 30 ℃ about 47 ℃, Since the temperature inside the aeration chamber is always maintained at 30-40 ° C. to maximize microbial propagation and wastewater treatment, thereby improving the efficiency of wastewater treatment and minimizing water pollution.
