Description

Provided with a heating and cooling means sewage disposal system

The present invention relates to a wastewater treatment apparatus, and more particularly, to a water-cooled hot / cooler of a wastewater treatment apparatus.

In general, wastewater generated from sewage, livestock wastewater and manure is decomposed by inflow into the wastewater treatment apparatus as shown in FIG. 1, to decompose wastewater introduced into the aeration chamber 1 through the wastewater inlet 2. In order to inject the microorganisms into the aeration chamber (1), while the activated microorganism is naturally activated in the aeration chamber (1) to decompose the dirt inside the aeration chamber (1).

Meanwhile, oxygen is supplied to the microorganisms in the aeration chamber 1 so that the microorganisms are actively activated. The air is supplied into the aeration chamber 1 through the blower 3 and the air supply pipe 4.

Here, when the temperature in the aeration chamber 1 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 or the like according to the operation of the blower 3 is about 74 ° C. The air at this temperature is further heated while passing through the solar air-heated metal air supply pipe 4, so that the temperature of the wastewater is approximately 42 when air of 74 ° C. or more is supplied into the aeration chamber 1. There was a problem such as rising to more than ℃ to slow the activity of microorganisms.

In addition, in winter, the cold air supplied through the blower (3) and the air supply pipe (4) into the aeration chamber (1) lowers the temperature of the wastewater to an appropriate temperature or less, thereby slowing down the activity of microorganisms, thereby degrading wastewater. There was a problem of lowering.

An object of the present invention for solving the above problems is to provide a wastewater treatment apparatus equipped with a hot / cooler for supplying air at an appropriate temperature inside the aeration chamber even in summer or winter.

The wastewater treatment apparatus provided with the present invention hot and cooler for achieving the above object includes an aeration chamber into which microorganisms are introduced and the wastewater flows, a blower for supplying air into the aeration chamber, and an air supply pipe connected to the aeration chamber and the blower. A wastewater treatment apparatus provided with a warm / cooler comprising: a water-cooled warm / cooler is installed in an air supply pipe to cool or heat air supplied from a blower to an aeration chamber.

Another characteristic of the wastewater treatment apparatus equipped with the present invention is a case in which the air cooler is connected to an air supply pipe at both ends, and the case is partitioned into a first space, a heat transfer space, and a second space. A plurality of first and second porous plates respectively provided in the heat transfer space and coupled to a plurality of through-holes formed at both ends of the first and second porous plates, respectively, to connect the first and second spaces. It consists of a water inlet pipe and a water outlet pipe respectively connected to the heat transfer space of the case to cool or heat the air passing through the plurality of air pipes as the water passes through the heat transfer space.

Therefore, by installing a water-cooled hot / cooler in the air supply pipe between the blower and the aeration chamber, water is supplied at approximately 18 ° C. in summer, cools 74 ° C. at 30 ° C., and water is supplied at 80 ° C. in winter. Heat the air at about 30 ° C. to about 45 ° C., thereby maintaining the temperature inside the aeration chamber at 30-40 ° C., thereby maximizing microbial propagation and waste water treatment, thereby improving wastewater treatment efficiency and water pollution. This can be minimized.

Specific features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings.

2, the wastewater treatment apparatus provided with the present invention hot / cooler is provided with an aeration chamber 11 through which wastewater is introduced through a wastewater inlet 12, and a blower is provided to supply air into the aeration chamber 11. 13 is provided, and the air supply pipe 14 is connected to the aeration chamber 11 and the blower 13.

Microorganisms are introduced into such aeration chamber 11 to decompose dirt while self-proliferating in the aeration chamber 11 by air supplied from the blower 13.

Meanwhile, the air supply pipe 14 is provided with a water-cooled hot / cooler 15 to cool or heat the air supplied from the blower 13 to the aeration chamber 11 according to the characteristics of the present invention, which is ion. The configuration of the cooler 15 is as shown in Figs.

That is, the case 16 is provided at both ends with an air supply pipe 14 connected thereto, and the case 16 is partitioned into a first space 21, a heat transfer space 22, and a second space 23. (16) The first and second porous plates 19 and 19 are provided in the interior, respectively, and the first and second porous plates 17 and 19 have a plurality of through holes 18 ( 20) is formed.

In addition, a plurality of air tubes 24 are provided in the heat transfer space 22 of the case 16, and the air tubes 24 have a plurality of ends formed at the first porous plate 17 and the second porous plate 19. It is coupled to the through holes 18 and 20 to connect the first space 21 and the second space 23.

The wastewater treatment apparatus equipped with the present invention hot / cooler having such a configuration drives the blower 13 to forcibly supply air to the aeration chamber 11 through the air supply pipe 14. The hot air rises to about 74 ° C. as it passes through the blower 13.

That is, assuming that the atmospheric temperature during the summer day is about 30 ° C, the air at 30 ° C rises to about 74 ° C while passing it by frictional heat generated during operation of the blower 13, and the air heated by solar heat. It is further heated while passing through the supply pipe 14.

The heated air is cooled to a predetermined temperature while passing through the water-cooled hot / cooler 15 of the present invention, and the air introduced into the first space 21 of the case 16 through the air supply pipe 14 is first Through the through-holes 18 of the porous plate 17 is divided into a plurality of air pipes 24 and flows through the heat transfer space 22.

At this time, water of about 18 ° C. is introduced into the heat transfer space 22 through the water inflow pipe 25, and low temperature water absorbs high heat of the air while contacting each air pipe 24, thereby cooling the air. The water absorbing the heat of the air is discharged through the water outlet pipe 26, the temperature of the air supplied to the aeration chamber 11 through the second space 23 of the case 16 is about 30 ℃ The temperature of the water discharged to the water outlet pipe 26 is about 22 ° C.

When the air passes through the air pipe 24 in the heat transfer space 22, water of about 80 ° C. introduced into the heat transfer space 22 through the water inlet pipe 25 contacts the plurality of air pipes 24, and thus the air pipe ( The air temperature in 24 is raised.

At this time, the temperature of the water discharged through the heat transfer space 22 to the water outlet pipe 26 is about 76 ℃, the temperature of the air supplied to the aeration chamber 11 through the air pipe 24 is about 45 ℃.

Therefore, the air heated to about 45 ° C. is supplied inside the aeration chamber 11 and mixed with the waste water cooled by the cold weather, thereby raising the temperature of the waste water slightly. As described above, the microorganism actively moves inside the aeration chamber 11. It is made to be 30-40 ℃ suitable for activity.

Therefore, according to the season and the temperature, the water of the temperature-cooled cooler (15) is passed through the appropriate temperature to properly regulate the temperature of the air supplied to the aeration chamber (11), so that the microorganisms act on the temperature inside the aeration chamber (11) It can be kept constant at a temperature of about 30-40 ℃ suitable for the following.
