問題もある。However, even if the liquid to be cultured containing actinomycetes and the like is simply left in the tank, these organic wastewater-purifying bacteria are not so active in the liquid to be cultured. However, the purification treatment efficiency was inferior. Also, in order to activate actinomycetes and the like, if air is blown into the culture treatment tank to maintain the inside of the tank in an aerobic state, a large-scale device is required, which cannot be adopted in a small-scale wastewater treatment facility. There is also a problem. Therefore, the present inventor has already proposed (Japanese Patent Laid-Open No. 3-72998).
We have tried to improve the culture treatment efficiency by applying a simple liquid treatment device to the culture medium. However, in the above-described liquid treatment device that utilizes two liquid flows, a swirling flow and an upward flow, the specific gravity is light and weak so that it contacts the upward flow, for example, useful bacteria such as actinomycetes are fixed. When such a useful bacteria-inducing material is installed, there is a problem that these inducing materials float up and are in a danced state, and the inducing material is quickly consumed. In addition, by utilizing the self-cleaning action of the above rivers, etc., in order to promote the decomposition of organic substances by maintaining the treatment liquid in an aerobic state and purify water,
An effective self-cleaning action cannot be achieved unless the supply of dissolved oxygen in the liquid is sufficient. In addition, it is very difficult to always keep the entire inside of a large-capacity processing tank in an aerobic state by aeration of the processing liquid, and there is a problem that the decomposition efficiency of organic substances is poor. Further, there is a problem that organic matter which is not removed by such bio-oxidation exists in the water to be treated such as waste water.

Since it can be easily generated, the unreacted liquid and the liquid to be cultured on the surface of the treatment tank constantly flow, and oxygen is constantly absorbed from the air in contact with the water surface. Be kept in a good state. As a result, the culture reaction of the liquid culture medium in the agitation tank is activated and bio-oxidation is promoted, and moreover, even organic substances that are difficult to decompose due to the active oxidation / reduction reaction of chemical agents such as oxidizing agents and reducing agents are forced. Water is decomposed and the organic sewage purifying bacteria such as actinomycetes in the liquid to be cultured are actively activated, whereby the purifying action of water is remarkably promoted. Furthermore,

As another effective mechanism for generating 0, for example, as shown in FIG. 2, a rotary cylinder 1 having a cylinder having the above-described shape is installed in the treatment tank 10 at substantially the center thereof, and this is used as a motor. A method of rotating at high speed with power such as M can be used. That is, with such a configuration, the upward flow 20 from the lower part to the upper part in the tank and the downward flow 30 from the upper part to the lower part in the tank are easily generated. As a result, the liquid to be treated in the treatment tank 10 is convected, and the inside of the treatment tank 10 is always kept in a uniform and aerobic state. Therefore, for example, actinomycetes contained in the liquid to be cultured are not contained. The organic sewage-purifying bacteria are efficiently propagated, and the water purification action is promoted. In addition, for example, in the unreacted liquid, hypochlorite, chlorine dioxide, potassium permanganate, hydrogen peroxide, ferrous sulfate, sulfite, bisulfite, oxygen-based chemical liquid LPS-1 (Linpearl Co., Ltd.) ) And an inorganic oxidative decomposition adsorbent LPS-2 (manufactured by Rinpearl Co., Ltd.) and other oxidizing agents / reducing agents, or a granular or powdery culture medium such as a useful fungus inducing material is injected, When treated in the stirring treatment tank, the chemicals are sufficiently mixed and stirred in the liquid, which shows excellent reactivity by the chemicals, and oxygen is sufficiently distributed in the tank, resulting in promotion of biological oxidation. In addition, organic substances that cannot be treated by biooxidation are forcibly decomposed by the oxidant to enable biooxidation, and as a result, the purifying action of water is promoted.

る。As shown in FIG. 2, a method for further enhancing the processing efficiency by further increasing the velocity and momentum of the upward and downward liquid flows that are forcedly generated as described above is as follows. Around the upper part of the rotary cylinder 1, it is preferable to provide a disc-shaped or rectangular forced plate such as a blind plate, a perforated plate or a concavo-convex plate so as to rotate with the rotary cylinder 1. That is, for example,
When a compulsory plate composed of a disc-shaped blind plate is provided around the upper part of the rotating cylinder 1 and is rotated together with the rotating cylinder, the liquid is rotated in the outer peripheral direction by the centrifugal force generated by the rotation of the disc as shown by the arrow in FIG. Since the water is efficiently transported toward the tank wall of the processing tank 10, the water level around the tank wall of the processing tank 10 becomes high and the pressure at the tank bottom increases, so that a tank bottom flow is generated toward the central part where the pressure is low. . As a result, a strong upward flow is generated in the cylinder in the substantially central portion, and the downward flow generated by this upward flow also has a high velocity and momentum. When the rotary cylinder 1 is a double cylinder, both the outer cylinder and the inner cylinder may be movable, or either one of the cylinders may be movable. Also, in the case of a double cylinder, the gap formed by the outer cylinder and the inner cylinder is used as the upward flow passage, but in the case where a forced plate is provided, this upward flow passage is A strong upward flow occurs, which results in a strong downward flow 30 on the outer circumference of the outer cylinder.

In addition, for example, the upper surface and the lower surface of the storage chamber 5 may be, for example,
It is preferable to form a mesh shape having an appropriate mesh of about 5 mm and the side surface to be a normal wall. Further, the capacity of the induction material storage chamber 5 varies depending on the type of liquid to be cultured.

好ましい態様である。Further, as shown in FIG. 3 and FIG. 4, the rotating cylinder 1 is rotated while generating an upward flow by a pump or the like in the lower part of the rotating cylinder or sending air by an air diffuser to give an upward flow. By doing so, the upward flow 20 in the rotary cylinder 1 is further forced, the aerobic state is further enhanced, and the efficiency of the culture treatment can be enhanced. Further, as shown in FIGS. 3 and 5, it is also possible to further increase the momentum of the upflow 20 and the downflow 30 by providing a propeller in the lower part of the culture treatment tank 10 coaxially with the rotary cylinder 1. This is a preferred embodiment as a means for increasing the efficiency of culture treatment. Further, as shown in FIG. 3, if a flow shield plate is provided on the upper part of the storage chamber 5, the downward flow 30 is efficiently guided into the storage chamber 5, so that the downward flow 30 can be more efficiently generated. It is preferable because it can be passed while being brought into contact with the induction material. Also, FIG.
As shown in (a), provision of the above-mentioned forced plate 2 is also a preferable mode in order to improve the speed and momentum of the liquid flow and improve the efficiency of the culture treatment. In addition, as shown in FIG. 4 (b), the gap between the double cylinder composed of the fixed inner cylinder and the rotating outer cylinder is used as the upward flow passage, and the through hole provided in the upper part of the outer cylinder is used. It is also preferable that the water flow is blown out vigorously. If the side surface of the induction material storage chamber 5 and the side surface of the culture treatment tank 10 are open, the downward flow 30 flows through this gap, and the contact efficiency between the downward flow 30 and the induction material is reduced. Therefore, as shown in FIG. 6, it is also a preferable embodiment to provide a gap plate at this position. Of course, it is also a preferable embodiment to apply these means described above to the same culture treatment tank at the same time.

という問題もある。However, even if the liquid to be cultured containing actinomycetes and the like is simply left in the tank, these organic wastewater-purifying bacteria are not so active in the liquid to be cultured. However, the purification treatment efficiency was inferior. Also, in order to activate actinomycetes and the like, if air is blown into the culture treatment tank to maintain the inside of the tank in an aerobic state, a large-scale device is required, which cannot be adopted in a small-scale wastewater treatment facility. There is also a problem. Therefore, the present inventor has already proposed (Japanese Patent Laid-Open No. 3-72998).
We have tried to improve the culture treatment efficiency by applying a simple liquid treatment device to the culture medium. However, in the above-mentioned liquid treatment device that uses two liquid flows, a swirling flow and an upward flow, when contacted with the upward flow , the specific gravity is light and weak, for example, useful bacteria such as actinomycetes are fixed. When the useful bacteria-inducing materials as described above are installed, there is a problem that these inducing materials float up and are in a dance-like state, so that the inducing materials are quickly consumed. In addition, by utilizing the self-cleaning action of the above rivers, etc., the treatment liquid is kept in a state capable of activating aerobic microorganisms to promote the decomposition of organic substances and to purify water. In this case, effective self-cleaning action cannot be achieved unless the supply of dissolved oxygen in the liquid is sufficient. In addition, it is very difficult to maintain the inside of a large-capacity processing tank in an aerobic state and in which microorganisms can actively move , even if the processing liquid is aerated. There is a problem of poor efficiency. Further, there is a problem that organic matter which is not removed by such bio-oxidation exists in the water to be treated such as waste water.
