Description

The present invention relates to a pest control method and apparatus for a septic tank .

The removal or prevention of harmful insects such as flies and mosquitoes generated in the septic tank is a difficult problem for users and managers.
As a method and apparatus for exterminating pests in a septic tank, a carrier impregnated or adhered with an insecticidal compound that continues to evaporate at room temperature is disposed in a space in the septic tank and is exterminated over a long period of time. (Patent Documents 1 and 2).

  In addition, as a conventional insecticidal method and apparatus, an insecticide is configured and installed in a container according to the shape, performance, action, etc. of the insecticide, and if necessary, these insecticide components are evaporated, volatilized and evaporated by a heater. Various proposals have been made for forcibly diffusing the light by a fan (Patent Documents 3, 4, 5, 6, 7, and 8).

Japanese Patent Laid-Open No. 9-12405 JP 2006-225408 A JP 58-4533 A Japanese Utility Model Publication No. 49-26141 Japanese Utility Model Publication No. 52-166107 No. 1-335671 Japanese Utility Model Publication No. 62-6211 JP-A-6-153752

However, the pest control agent consisting of pesticidal compounds into the septic tank disposed in the space portion, be disinfected for a long time by volatilization of the insecticidal component, it is difficult to mention effective as assumed It is solved.

  The pest control agent is formed by adhering and impregnating a pest-like carrier made of paper, plastic, etc., and suspending the carrier in the septic tank. During the initial period of action, pest control has been carried out due to the insecticidal effect, but the waste water accumulated in the septic tank over time, the water that evaporates due to sewage, etc., entering dust, dust, etc. adhere to the carrier, Prevents the volatilization of medicinal ingredients and reduces extermination ability.

  Furthermore, for example, in a merged tank, a lot of bubbles such as detergents may be generated, and the space in the tank may be filled with bubbles. In such a case, a pest control carrier is also encased, and air circulation is also suppressed. After that, the dirt is remarkably adhered and the deterioration of the pest control ability is accelerated.

In addition, scattered air, sludge, and the like may adhere to the carrier due to air released from the aeration mechanism provided at the bottom of the water purification tank.
When the occurrence of pests increases, there are many cases where the ability decreases and some drugs adhere to the medicine itself, and it is often difficult to achieve the insecticidal effect for the planned period, for example, three months.
Of course, there is no problem if the maintenance and inspection of the insecticide composed of insecticidal compounds is frequently performed, but maintenance and inspection is generally a work to be avoided, and it is left to the contractor. There is almost no cost problem, and it is difficult to carry out at all times, and it is often replaced after the ability of the pest control agent is reduced.

Therefore, in the present invention, by avoiding the direct operation to the septic tank that hangs the pest control carrier directly in the septic tank, anyone can easily carry out the carrier replacement work, and the efficacy of the pest control agent is We propose a method and an apparatus that can fully exert the insects at all times and surely control the pests.

  In addition, a method and an apparatus for providing a pest control effect by providing a sufficient effect of the pest control agent in the septic tank with a constant air flow without specifying an installation place suspended in the septic tank are proposed.

In order to achieve these objects, the present invention allows a blower to continuously aerate the inside of a septic tank through an air diffuser, and to store or install an insecticidal compound that volatilizes at room temperature in a sealed container whose lid can be opened and closed. The air containing the insecticidal compound that volatilizes in the sealed container is sent to the discharge pipe or the septic tank through the air supply pipe via the pump pressure, and reaches the space between the lid and the sewage accumulated in the septic tank. It is a pest control method for a septic tank , characterized in that

In addition, a septic tank is provided with a diffuser pipe for sending aeration air with a blower, while a sealed container whose lid can be freely opened and closed is provided with a storage or installation part for an insecticidal compound that volatilizes at room temperature, and the sealed container is operated by a pump. The blower was allowed to communicate, and the insecticidal compound volatilized in the sealed container could be sent to the septic tank via an air pipe connected to the sealed container or through a discharge pipe for sending sewage and miscellaneous wastewater to the septic tank. A pest control device for a septic tank characterized by

Further, the diffusing pipe sending air to the septic tank coupled to a blower, a branch pipe provided, connecting the branch pipe in a sealed container, sends the flue coupled at one end to the sealed container, sewage, the gray water in the septic tank A pest control device for a septic tank , characterized in that it communicates with a discharge pipe or a septic tank .

The inlet 23 is connected to a blower 26 via a float 25. It is. The outlet 24 is connected to the discharge pipe 13 by an air supply pipe 201.

  Reference numeral 27 denotes a hermetic lid, which can be freely opened and closed so as to have light pressure resistance. The sealed container 20 is provided with a frame 29 on the upper side thereof, or directly provided on the sealed lid 27 with locking portions 29, 29. is there. As the locking portion 29, various other types such as a bag for storing the carrier, a net bag, a container such as an open container, or an installation member can be used.

  As a pest control agent, a compound such as dichlorovos, a pyrethroid compound, a fluorobenzyl ester compound, dimethyl dichlorovinyl phosphate, or the like is impregnated with an insecticidal compound such as plastic or paper on a plate or a sheet-like carrier 28 and formed. Is used.

An appropriate number of the carriers 28 are accommodated in the sealed container 20. Although it depends on the pest control agent, it is generally considered that a carrier amount of about 500 to 10000 cm ² per 1 m ³ of the space in the septic tank 1 is preferable.

  The sealing container 20 is provided with a diffusion plate 30 having through holes 301, 301... Corresponding to the inlet 23, diffuses the air sent from the inlet 23, and softly hits the carriers 28, 28. The insecticidal compound that volatilizes from the carrier 28 is blown and sent out from the outlet 24.

  Air is sent to the inlet 23 from the blower 26 via the air adjustment valve 33 and the float 25. A silencer box 32 is connected to the blower 26 via an air relief valve 31.

34 is a blower which sends air to the septic tank 1 through the air diffusing pipe 35 to promote the activity of aerobic bacteria and promote the decomposition of waste water and sewage.
Of course, when anaerobic bacteria are used, it is better not to send air into the tank or chamber, and it is of course possible to cut off the air with an air feed prevention mechanism or the like. .

Next, the insecticidal method of the present invention will be described.
The sealing lid 27 of the sealed container 20 is opened, and the carriers 28, 28,... The sealing lid 27 is closed and the operation is started.
First, the blower 26 is operated, the air relief valve 31 is closed, the air adjustment valve 33 is opened, and air is fed into the sealed container 20 through the float 25.

At that time, the air hits the diffusion plate 30 to weaken the force, passes through the through holes 301 and 301, and diffuses into the sealed container 20.
Then, the insecticidal compound that evaporates is wrapped in the air by the carriers 28, 28..., Is sent out from the outlet 24, passes through the exhaust pipe 201, passes through the discharge pipe 13, and is sent into the septic tank 1. In the septic tank 1, waste water and sewage stored in the chambers 3, 3... Above the septic tank 1 are decomposed and purified by aerobic bacteria, and are sequentially discharged from the discharge port 7. At this time, air is always sent to the septic tank 1 through the air diffuser 35 from the blower 34 , and the waste water and sewage are continuously aerated.

In the conventional septic tank, this air contacts over the surface of the drainage and sewage and spreads to the respective chambers 3, 3..., But flows as it is from the discharge port 7, and above the septic tank 1, especially the lids 10, 10. There is little air flowing in the vicinity.
In the case of the present invention, air containing an insecticidal compound is sent out from the discharge pipe 13 and travels in the space between the drainage, sewage and the septic tank 1, particularly in the vicinity of the lid 10. It goes down on the drainage and sewage inside, but the space above the drainage and sewage is filled with an insecticidal compound, fills the vicinity of the lids 10, 10... Above the septic tank 1, and is discharged from the discharge port 7.

  For this reason, pests are easily generated and have a raw odor, and the space 101 of the septic tank 1 is filled with the insecticidal compound, and the state is maintained, and the pest habitat is extinguished.

A second embodiment shown in FIG. 2 will be described.
The basic type is the same as in FIG. 1, but in this embodiment, the operation of sending air to the air diffuser 35 and the operation of sending air to the sealed container 20 are common in the embodiment implemented in the small-scale septic tank. This is a method and apparatus performed only by the blower 34. In this apparatus, a diaphragm type is usually used as a pump.

That is, the air from the blower 26 is sent from the diffuser pipe 35 and the diffuser pipe 35 to the branch pipe 351 reaching the sealed container 20 through the branch air adjusting valve 352.
As a result, the aeration air is sent to the septic tank 1 from the diffuser pipe 35 and at the same time, the air containing the insecticidal compound is sent to the discharge pipe 13 or the inlet 8.
In this case, the outlet of the air supply pipe 201 is inserted into the discharge pipe 13, but can be set to any of the inlets 8 of the septic tank 1.

Next, the embodiment shown in FIG. 3 will be described.
In this embodiment, the hermetically sealed container 20 contains a liquid insecticidal solution, which is a liquid insecticidal compound, and is foamed from the liquid by air sent through the float 25 to promote the volatilization of the liquid and float. By sending air containing volatile compounds from the outlet 24 and continuing to dissipate air containing volatile compounds in the septic tank 1 via the air supply pipe 201, eliminating the pest habitat and giving a pest control effect I can do it.
Of course, the pest control solution, which is an insecticidal compound, can be used in either the first embodiment or the second embodiment.
