Description

Septic tank system

The present invention relates to an apparatus, and more particularly to a septic tank system for treating sewage.

The septic tank is a facility to purify only manure, which is a solid or solid pollutant, generated in flush toilets by sedimentation and decomposition. The main mechanism of wastewater treatment in these septic tanks is the 'methane fermentation method' of organic matter by microorganisms, and there are aerobic digestion and anaerobic digestion.

In addition, the composition of the domestic septic tank is largely composed of a corruption tank, an oxidation tank, and a disinfection tank. In corruption tank, corruption and fermentation of organic matter proceeds, and oxidizing action of aerobic bacteria occurs due to inflow of air while staying in the oxidation tank for 16 to 24 hours. In the case of disinfecting tank, sterilization is carried out by using disinfectant of various kinds of sewage while staying for 15 minutes.

The types of septic tanks are divided into a single septic tank and a combined septic tank. The single septic tank can be classified into a corrupt tank, a crypto tank, a sprinkling type decay tank, a spraying filter, an aeration method, and a contact aeration. In addition to this treatment method, the septic tank can be selected and selected according to the number of users

Civil complaints and disputes are increasing due to odors generated during the purification process and storage of sewage. Since living odor is a problem that directly relates to the quality of life, a device for supplying air or a medicine is put in to solve the problem. However, even this method has a limitation in completely removing the odor.

In addition, pests may be generated during the purification or storage of sewage. To solve this problem, there is a method of applying ginkgo leaf or loach, insect screening, or injecting chemical insecticide. Insects such as mosquitoes and flies are highly fertile and fit well with the septic environment, making them difficult to eradicate, and the use of indiscriminate insecticides causes new environmental problems.

The present invention provides a septic tank system capable of eliminating odors or pests generated in a purification process without being discharged to the outside, and capable of removing odors and pests environmentally. However, these problems are exemplary and do not limit the scope of the present invention.

According to an aspect of the present invention, there is provided an aeration tank in which an inner space is sealed and an aeration device is installed in the inner space, a sedimentation tank installed separately from the aeration tank, the sludge being treated in the aeration tank, And an absorption tank in which the stored absorption fluid absorbs a first gas or foreign substance generated in the aeration tank and discharges it to the settling tank.

The aeration tank may include a discharge pipe, one end of which extends from one side wall, and the other end of which is installed to be submerged in the absorption fluid of the absorption tank.

In addition, when the pressure of the first gas stored in the upper portion of the aeration tank rises, the first gas and the foreign matter may move along the discharge pipe and be collected in the absorption fluid.

The apparatus may further include a connection pipe connecting the aeration tank and the sedimentation tank so that the sewage flows from the aeration tank to the sedimentation tank and installed lower than the absorption tank.

The absorber may include an inlet pipe for introducing the absorbing fluid into the inner space, a take-out tube installed on the absorbing fluid for discharging the second gas separated from the absorbing fluid to the outside, And a discharge pipe for discharging the refrigerant to the outside.

In addition, the absorption tank may include at least one baffle unit installed in the inner space of the absorption tank so as to be submerged in the absorption fluid.

The baffle units may be spaced apart from each other in the height direction, and may be arranged so that at least a part of the baffle units are overlapped with each other.

Further, the baffle unit may be installed so as to be inclined with respect to the bottom surface of the absorption tank.

Further, the absorbing fluid stored in the absorption tank may be acidic.

The absorption fluid stored in the absorption tank may be at least one of hydrochloric acid (HCl), sulfuric acid (H2SO4), sodium hypochlorite (NaClO), chlorine dioxide (ClO2) and potassium permanganate (KMnO4) have.

The aeration tank may further include a pressure sensor for measuring a pressure of the first base and a branch pipe for opening the first base if the pressure of the first base is equal to or higher than a predetermined pressure and for discharging the first base to the outside.

According to an embodiment of the present invention as described above, the septic system can prevent bad odors or foreign substances generated during the purification process from being discharged to the outside, thereby improving the sanitary environment.

The septic tank system can separate sewage and odor from each other and treat them to improve the efficiency and cleanliness of the purification process. In particular, the efficiency and cleanliness of the purification process can be improved by removing odors by neutralization reaction in the absorption tank.

The septic system can easily remove odors because the odor stays in the absorption tank for a considerable time by the baffle unit. Of course, the scope of the present invention is not limited by these effects.

1 is a plan view conceptually illustrating a septic tank system 100 according to an embodiment of the present invention.

1, the purification system 100 includes a decay tank 10, a flow rate control tank 20, an aeration tank 110, a settling tank 120, and a treatment tank 50.

The decay bath (10) is a place where sediment is suspended in the sewage. The flow rate in the corruption tank (10) must be slowed, and the sewage should stay longest. The decay bath 10 is relatively largest in order to slow the flow rate of the sewage and to increase the rectification time.

The flow rate adjusting tank 20 is provided between the decay bath 10 and the aeration tank 30. The flow rate adjusting tank 20 can control the flow rate of the sewage flowing into the aeration tank 30. The flow rate regulating tank 20 can regulate the flow rate of the sewage, so that the sewage can be suddenly introduced into the aeration tank 30 and the sewage can be treated stably.

The aeration tank 30 can pass the sewage into the filter medium (not shown) to purify the sewage. The aeration tank 30 is provided with an aeration device, and oxygen generated in the aeration device can react with the sewage to purify the sewage. Normally, the sewage is rectified in the aeration tank 30 for about 16 hours to 24 hours, so that insects such as mosquitoes can be generated.

The settling tank 40 is connected to the aeration tank 30 and can remove foreign matter in the sewage. The treatment tank 50 is connected to the settling tank 40 and can sterilize the sewage introduced from the settling tank 40 using an oxidizing agent or the like.

FIG. 2 is a side view showing a partial configuration of FIG. 1, and FIG. 3 is a side view showing a side surface of the absorption tank 130 of FIG.

Referring to FIGS. 2 and 3, the aeration tank 110, the settling tank 120, and the absorption tank 130 can be described in detail as follows.

The aeration tank 110 may include an aeration device 111, a discharge pipe 112, a pressure sensor 113, a branch pipe 114, and a first valve 115. The aeration tank 110 is provided with an aeration device 111 in an inner space and can supply air to the stored sewage W. [ The aeration tank 110 may be installed so that the internal space is hermetically sealed. The aeration tank 110 may be installed so that the front surface is clogged by the outer wall. Therefore, foreign substances such as odors and pests generated in the aeration tank 110 do not directly flow out to the outside.

The aeration tank 110 may include a discharge pipe 112 for transferring a first gas such as an odor generated during aeration to the absorption tank 130. One end of the discharge pipe 112 extends from one side wall of the aeration tank 110 and the other end of the discharge pipe 112 is installed to be submerged in the absorption fluid M stored in the inner space of the absorption tank 130. The bubble generator 112a is installed at the end of the discharge pipe 112 so that the first base G1 can be effectively discharged from the discharge pipe 112. [

The pressure sensor 113 can measure the pressure of the first base G1 stored in the internal space of the aeration tank 110. [ The first base G1 such as a malodor generated at this time is supplied to the upper side of the aeration tank 110 through the sewage W . The pressure sensor 113 senses the internal pressure of the aeration tank 110 to determine whether the first valve 115 is opened.

The branch pipe 114 is branched from one side of the aeration tank 110. When the internal pressure of the aeration tank 110 is high, the first base G1 can be discharged to the outside to lower the internal pressure. The branch pipe 114 can open the first valve 115 to discharge the first base G1 to the outside if the pressure of the first base G1 is equal to or higher than a predetermined pressure.

The connection pipe 116 is installed to connect the aeration tank 110 and the settling tank 120. The sewage W can be moved from the aeration tank 110 to the settling tank 120 through the connection pipe 116. The connection pipe 116 is installed at a position lower than the absorption tank 130 and can directly connect the aeration tank 110 and the settling tank 120.

Conventionally, the upper part of the aeration tank is installed to be open. In order to eliminate the positive pressure generated by the aeration device and to eliminate the possibility of explosion of the aeration tank, the aeration tank is installed with the top open. However, the odor of stored sewage is leaked to the outside, and the hygienic environment is deteriorated by the pest which is generated in the aeration tank.

Since the aeration tank 110 is hermetically sealed in the inner space, odor, foreign matter, and pest may not leak to the outside. When the aeration device 111 is driven, the first base G1 such as an odor is separated from the sewage W and stored in the upper portion of the aeration tank 110. [ That is, since the positive pressure is generated in the aeration tank 110, the first base G1 can move to the absorption tank 130 having a low pressure along the discharge pipe 112. Since the front surface of the aeration tank 110 is clogged, the generated first base G1 is not directly discharged to the outside but is discharged through the discharge pipe 112 only.

Since the aeration tank 110 stays for a considerable time in the aeration tank 110, a foreign matter such as a mosquito or the like separated from the sewage in the aeration process can move along the first base G1. Since the front surface of the aeration tank 110 is closed, insects and foreign matter are not directly discharged to the outside, but are discharged through the discharge pipe 112 only with the movement of the first base G1.

The settling tank 120 is installed separately from the aeration tank 110, and sewage W processed in the aeration tank 110 is introduced. The sewage W may be introduced into the sedimentation tank 120 through the connection pipe 116. In addition, the absorption fluid (M) stored in the absorption tank (130) may be introduced into the sedimentation tank (120). The wastewater W is directly introduced from the aeration tank 110 and the first base G1 is dissolved in the absorption fluid M and can be introduced from the absorption tank 130. [

The absorption tank 130 is disposed between the aeration tank 110 and the sedimentation tank 120, and the absorption fluid M can be stored or flowed therein. The absorbing fluid M can absorb foreign matter such as a first gas G1 or insect pests generated in the aeration tank 110 and can move to the settling tank 120 to discharge the first gas G1, have.

The absorbing fluid M is a fluid capable of absorbing a foreign substance such as a first gas G1 or a pest, and is not limited to a specific substance. For example, a fluid stored in an external storage tank, groundwater, or tap water.

Further, the absorption fluid M may be an acidic fluid. The first gas G1 generated in the aeration tank 110 may be a basic ammonia gas. The absorbing fluid M reacts with the first gas G1 and changes to neutral so that the first gas G1 can be safely removed. For example, the absorption fluid (M) is a fluid (H) in which at least one of hydrochloric acid (HCl), sulfuric acid (H2SO4), sodium hypochlorite (NaClO), chlorine dioxide (ClO2) and potassium permanganate (KMnO4) Lt; / RTI >

division Measure 1 Measure 2 Absorbing bath pH 2.28 3.76 Ammonia concentration in aeration tank 65 ppm 70ppm Absorbing ammonia concentration 10ppm 15 ppm Temperature 21.7 DEG C 20.2 DEG C

The absorption fluid was an acidic solution in which sulfuric acid was dissolved, and the first gas used was ammonia gas. Referring to Table 1, when the pH of the absorption tank was 2.28, about 85% of the ammonia gas was removed. Further, when the pH of the absorption tank was 3.76, about 80% of the ammonia gas was removed.

That is, the absorbing fluid M generates a neutralization reaction with the first gas, thereby effectively removing the first gas. In addition, since the absorption fluid M discharged to the settling tank 120 is neutral, the first base G1 can be eco-friendly.

The absorption tank 130 may include an inlet pipe 131, a second valve 132, an outlet pipe 133, a discharge pipe 134, a third valve 135 and a baffle unit 136.

The inlet pipe 131 may introduce the absorbing fluid M into the inner space of the absorption tank 130. A second valve 132 is provided in the inlet pipe 131 to control the flow rate of the absorbing fluid M. The absorption fluid (M) is stored in the absorption tank (130) for a certain period of time, and then discharged to the settling tank (120). The second valve 132 can be charged again when the absorbing fluid M is discharged.

The extraction pipe 133 extends from the upper wall of the absorption tank 130 and can discharge the second base G2 stored in the absorption tank 130 to the outside. If the second base G2 such as an odor in the absorbing fluid M is disadvantageous, it is collected at the upper part of the absorption tank 130. [ The extraction pipe 133 discharges the second gas G2 stored in the upper portion of the absorption tank 130 to maintain the stability of the absorption tank 130. [

The discharge pipe 134 extends from the lower wall of the absorption tank 130 and can discharge the absorption fluid M to the settling tank 120. A third valve (135) is provided at one side of the discharge pipe (134) to adjust the flow rate of the absorbing fluid (M) discharged. The absorption fluid M stored in the absorption tank 130 for a certain period of time is discharged to the settling tank 120 through the discharge pipe 134 when the third valve 135 is opened.

Referring to FIG. 3, a plurality of baffle units 136 may be disposed in the inner space of the settling tank 120. The baffle unit 136 may disturb the movement of the first base G1 flowing through the discharge pipe 112 so that the first base G1 is absorbed by the absorbing fluid M. [

The baffle unit 136 is installed inside the absorption tank 130 so as to be immersed in the absorption fluid M. The baffle unit 136 is provided so as to be spaced apart in the height direction and may interfere with the fluidity of the first base G1 moving upward.

The baffle unit 136 may be fixed to the side wall of the absorption tank 130. The baffle unit 136 may be installed such that some regions overlap. The first baffle 136a and the second baffle 136b may be installed to overlap each other by a distance d. The first base body G1 can be left in the absorption tank 130 for a considerable period of time without being directly discharged to the outside by the overlapped region.

Referring to Table 1 above, in the absorber without baffle, the first gas as ammonia resides in the form of air bubbles on average 0.267 seconds, but when the baffle is formed, the residence time of the first gas increases to 0.963 seconds. If the residence time of the first gas in the absorption tank is increased, the contact time and area with the absorption fluid are increased, and the first gas can be effectively removed.

The septic tank system 100 according to an embodiment of the present invention can prevent bad odors or foreign substances generated in the purification process from being discharged to the outside, thereby improving the sanitary environment. The front surface of the aeration tank 110 is clogged, and the gas generated through the discharge pipe is discharged, so that it is not directly discharged to the outside.

The septic tank system 100 can separate sewage and odor from each other and treat them to improve the efficiency and cleanliness of the purification process. The wastewater W purified in the aeration tank 110 moves directly to the settling tank 120. The malodorous or foreign matter generated in the purification process moves to the settling tank 120 through the absorption tank 130. [ In particular, the odor can be removed by the neutralization reaction in the absorption tank 130. Since odor and foreign matter are stored in the absorption fluid (M) and then transferred to the sedimentation tank (120), the efficiency and cleanliness of the purification process can be improved.

The septic system 100 can easily remove the odor since the odor stays in the absorption tank 130 for a considerable time. The baffle unit 136 interferes with the movement of the gas, so that the gas can be effectively dissolved in the absorbing fluid M.

4 is a side view showing a modified example of the absorption tank 130 'of FIG.

Referring to FIG. 4, the absorption tank 130 'of the modification is characterized by the shape and arrangement of the baffle unit 136', which will be described in detail.

The baffle unit 136 'may be installed to be inclined with respect to the bottom surface of the absorption tank 130'. Since the baffle unit 136 'is formed to be inclined downward, the first base G1 can stay in the absorption tank 130' for a long time.

Since the first baffle 136'a and the second baffle 136'b are formed to be inclined downwardly so that the first base G1 discharged from the discharge pipe 112 is positioned at the bottom of the first baffle 136'a . Then, since the first baffle 136'a and the side wall are brought into contact with each other in the region where the first baffle 136'a is in contact, the residence time of the first base G1 can be increased.

When the first base G1 rises through the first baffle 136'a, it moves along the bottom of the second baffle 136'b. Then, since the second baffle 136'b is collected in the region where the side wall contacts with the second baffle 136'b, the residence time of the first base G1 can be increased.

In addition, since the first baffle 136'a and the second baffle 136'b arranged to be inclined have areas overlapping with each other, the first base G1 can remain in the absorption tank 130 'for a long time have.

The absorption tank 130 'can guide the baffle unit 136' to move the first base G1 and allow the first base G1 to remain in the inner space of the absorption tank 130 'for a long time. The first base G1 can be easily dissolved in the absorbing fluid M, so that the first base G1 can be effectively removed.
