The present invention relates to a combined treatment manure septic tank that can purify and reuse domestic wastewater and livestock wastewater, and can reduce water resources or reduce wastewater pollution.

About 70% of the root causes of water pollution in rivers are domestic wastewater, followed by the discharge of harmful substances by industrial wastewater and livestock wastewater. In order to purify this wastewater, research and development is actively progressing.

For example, Korea Invention Patent No. 062359 (Japanese Zoil Performance Co., Ltd.) and Japan's Fuji Green Industrial Co., Ltd. have been researched and developed, and the most commonly used merger treatment septic tank (LP, LC type) in Japan.

Briefly explaining the former septic tank structure and operation (see FIG. 1), the first separation chamber (2), the second separation chamber to oxidize, reduce and decompose wastewater introduced from the wastewater inlet (1) by biological action (11), purified by anaerobic bacteria in the process through the third separation chamber 12, the preliminary filtration chamber (3), the air supply pipe installed in the first aeration chamber (5), the second aeration chamber (10) Purified by aerobic bacteria by (4) and discharged from the pump chamber (7) to the drain pipe (6) through the settling chamber (9) and the stabilization tank (8).

The latter has the same function as the former, but there is only one separation chamber (anaerobic layer) and one aeration chamber (aerobic layer), so the structure is simple, and the installation area is about 50% or less than the former, but about 80% of the discharged water BOD. The degree is purified. On the other hand, the former installed the separation chamber and the settling chamber more than twice as much as the latter (in case of the same treatment water capacity), and used the small container (yakult container) to increase the aeration effect. However, the installation area is more than twice as large as the latter, and it is inconvenient to maintain the power consumption due to long-term aeration and regular replacement of the filter media of the stabilization tank. There are problems that the date requires.

The present invention compensates for the problems of the conventionally described designs, and utilizes a large amount of artificial wastewater by using EM (Effective Microorganism, EM International, Dec. 9, 1994 (Friday), Environment / Science). It is an object of the present invention to provide a combined treatment manure septic tank capable of highly biologically purifying wastewater because it simultaneously grows and grows microorganisms and naturally formed anaerobic bacteria and aerobic bacteria.

Hereinafter, the embodiment will be described in detail with reference to the embodiments in FIGS. 2 and 3.

This merged-treated manure septic tank 21 can be applied to the small size (FRP agent) which can be transported, and the concrete agent which is promoted in the field. Inlets 22 and outlets 37 through which various wastewaters can be introduced are provided.

There is a first sedimentation separation chamber 23 and a second sedimentation separation chamber 24 for sedimenting and separating the introduced wastewater.

Numeral 25 denotes a flow regulator for allowing the wastewater to flow into the first contact aeration chamber 26 in a constant amount. (28) is the second contact aeration chamber, and on the dividing wall from (26) there is a drain. In the center of the first and second contact aeration chambers, for example, aeration pipes 27 and 29 of plastic pipes having a diameter of about 12 CM are located in the vertical direction, and an air supply pipe 30 through which air is supplied is installed.

In order to maximize the area where microorganisms attach and increase the turning efficiency of the treated water between the aeration tanks on both sides and the inner wall of the contact aeration chamber, a large number of filter media are filled in disorder. As the contact medium, for example, vinyl chloride, polyethylene, or the like, a diameter of about 2 cm, a length of 4 cm, a thickness of about 0.005 cm, or a cylindrical pipe or a ring made of polyvinylidene chloride can be used.

(26) (28) On the inner bottom, a shelf is laid about 20CM above the bottom, and the aeration tank and contact media are placed on this shelf. Although not shown in the drawing, the backwash engine is installed in the same type as the air supply pipe in both aeration cylinders.

(31) is for returning sludge to the first settling separation chamber using the principle of an air lift pump (AIR-LIFT PUMP) that uses air injected from an air supply pipe to sludge generated at the bottom of both contact aeration chambers. It is plumbing.

Reference numeral 33 is a sedimentation chamber provided after the second contact aeration chamber, and a drain hole is provided on the partition wall with reference to 28. Reference numeral 35 denotes a stabilizer and 34 denotes a card-injection exchange filter medium made from activated carbon or charcoal made by burning straw in a vacuum. For example, it is shaped like a matchbox with a width of about 20CM, and it is made of stainless steel or plastic mesh so that the treated water can pass in the front and rear directions, so it moves only up and down. A drain hole is provided on the dividing wall of (33) and (35). Reference numeral 36 denotes a sterilization chamber and a pump chamber installed after the stabilization tank. The clear treated water that has passed through the replacement filter medium is disinfected in the disinfection room and discharged through the outlet 37 by a pump. Although not shown in the drawings, a manhole is installed on each chamber, and the air pump is equipped with a timer so as to operate the pulse aeration.

The structure of this embodiment has been described above. The following describes the operation. An aqueous solution of EM diluted about 100 times with water is added to each chamber of (23) (24) (26) (28) (33) of about 1/1000 of the treated capacity. Various wastewater flowing into the inlet 22 passes through both sedimentation chambers 23 and 24, where sedimentation and separation of solids occur, resulting in anaerobic degradation by EM and naturally formed microorganisms due to sewage retention. It is separated into suspended solids and intermediate water. The intermediate water in the upper layer of the second sedimentation separation chamber 24 is supplied to the second aeration chamber after the first contact aeration chamber 26 in a constant amount through the flow regulating device 25. At this time, the air pump is turned on at intervals of about 20 minutes by a timer attached to an air pump (not shown) so that EM and naturally occurring aerobic and anaerobic microorganisms coexist actively in the contact media filled in both aeration chambers. , The OFF operation is periodically supplied with air through the air supply pipe 30 to repeat the periodic aeration action. Periodically, the aeration is stopped and air is injected from the bottom of both contact aeration chambers through a back-tubing pipe (not shown in the drawing, same as (30)). It precipitates in and is conveyed in the 1st settling separation chamber 23 by the action of the sludge conveyance piping and the air lift pump by air blowing force.

The treated water treated by both contact aeration chambers was passed through the settling chamber of (33) followed by the stabilized card filter medium (34). The discharged water (37) through the sterilization chamber containing the solid chlorine material and the pump chamber (36). To be discharged.

In describing the effect of experimenting with the present invention, the BOD of the influent wastewater was about 200 ppm, and the aqueous solution diluted with EM using this purifier was about 1/000 of the treated capacity as described in the above operation (23) (24) Two weeks after the (26) (28) and (33) injection, the final treated water discharged to the outlet 37 was measured, and the average value was 2 ppm of BOD.

As a factor that can achieve a good result in a short time, EM is an aerobic and anaerobic effective microorganism group of about 80 kinds artificially cultured, which promotes oxidation, reduction and decomposition of waste water.

In addition, air pumps (not shown) are turned on and off at regular intervals, and the small cylindrical pipe surfaces filled in both contact aeration chambers actively coexist with a large number of aerobic and anaerobic microorganisms. It can cause to be small. In addition, by filling a large amount of small contact media 32 into both contact aeration chambers in an orderly manner, the surface area can be increased, and the water purification efficiency can be provided with a high purification efficiency. In addition, since the filter material 34 is a card type, it is easy to replace and periodic aeration can reduce the lifespan and power consumption of the air pump by about 1/2, thereby reducing maintenance costs and economic losses.

As described above, the present design compensates for the disadvantages of the conventional septic tank having a large installation area, economic burden due to long-term aeration, and the hassle of exchanging filter media, and the structure is simple. It is a feature of the present invention that a high performance septic tank can be installed at a lower price than physical and chemical.
