Description

  TECHNICAL FIELD The present invention relates to a sewage treatment facility containing human waste and organic sludge, and more particularly to a sewage treatment facility having a structure in which organic matter in sewage is ultrafinely refined and solubilized, treated with fermentation bacteria, and sludge production is zero.

Conventional treatment facilities for sewage including human waste include nitrogen oxides contained in organic wastewater such as sewage, human waste, and various industrial wastewater in an anaerobic treatment tank with a granular sludge bed of methane fermentation bacteria. There is a biological denitrification method in which denitrifying bacteria are propagated around granule sludge while being circulated in an upward flow and biologically reduced and denitrified (see Patent Document 1). This can granulate the microbial cells themselves to hold the microbial cells at a high density, and can be operated at a high volume load.

In the solubilizer, the two or more adjacent cylindrical walls in a substantially concentric state are supplied to either the annular flow path communicating with each other via a connecting portion or the flow path in the innermost cylindrical wall. A fluid to be treated, such as water containing flaky organic matter, is sucked by a jetting unit from a suction unit different from the supply unit, and is pressurized and supplied to the annular flow path to be 8 m / second in the circumferential direction. The above high-speed flow is generated, and the flaky organic matter is micronized to a micron level by mechanical force such as shearing action by the high-speed flow, and the impact is received by the rotating body rotating at a high speed of 150 rpm or more in the cylindrical container. In the same way, it will be micronized to the micron level, the cell membrane of the dead cells forming sludge is destroyed, and the cytoplasm is easily melted in the fluid. In that case, only the injection means such as a pump and a rotating body that is rotationally driven by a motor or the like are used as operating components, and stable continuous operation is possible over a long period of time with almost no maintenance. Yes, even if it is a plant material containing fibers or organic matter of fatty animal substances with a lot of fat, it is continuously and efficiently made ultrafine because there are no small gaps where clogging occurs, resulting in accelerated solubilization Is done. When a processed fluid containing organic matter that has been ultra-fine and greatly expanded in specific surface area is supplied to an aeration tank or the like, such organic matter is quickly consumed by various protists and bacteria such as fermentation bacteria. Biodegraded. For example, when the specific surface area of a spherical organic substance having a radius of 1 mm is only 0.00120 m ² / g, but is made into a spherical shape having a radius of 0.0001 mm, the specific surface area is 12.0 m ² / g. As many as 10,000 times the number of bacteria inhabiting the aeration tank can be attached to the surface, and it is possible to efficiently dispose of organic matter and mass culture of useful bacteria. it can. When only water is supplied to the solubilizer, water is treated. This solubilizer is referred to as a water ultrafine refiner in the case of water-only treatment.

  The cylindrical container shares an outermost cylindrical wall forming a casing and a bottom wall in the casing, has a top wall above the casing top wall, and has the connecting portion inside the casing near the top wall. The ejecting means has a suction portion for the fluid to be processed on the bottom wall of the internal cylindrical wall, and the suctioned fluid to be processed is tangential to the outermost annular flow path. Since the outermost cylindrical wall of the casing has an injection portion that injects in the direction, the organic matter contained in the fluid to be treated is caused by the difference in flow rate between the fluid on the wall surface and the fluid moving at high speed in the outermost annular channel. Due to the shearing action, the micronization is promoted by collision with the bottom wall by suction from the bottom wall of the inner cylindrical wall. Furthermore, the fluid to be treated that has been subjected to the shearing action in the outermost annular flow channel is in a gas-liquid mixed state in the relatively large space in the projecting portion of the upper projecting internal cylindrical wall that has flowed in through the connecting portion, and rotates. Subminiaturization is further promoted by receiving an impact from a rotating body that has a relatively small resistance and rotates at a high speed.

  The cylindrical container has a simple configuration having an outermost cylindrical wall forming a casing, and an inner cylindrical wall sharing a bottom wall in the casing and spaced from the top wall of the casing. Has a suction portion for the fluid to be processed on the bottom wall of the inner cylindrical wall, and an injection portion for injecting the fluid to be processed such as sucked water into the outermost annular channel in a tangential direction. By having it on the wall, the organic matter contained in the fluid to be treated is subjected to a shearing action due to the flow velocity difference between the fluid on the wall surface and the fluid moving at high speed in the outermost annular channel, and from the bottom wall of the inner cylindrical wall Ultra-miniaturization is promoted by collision with the bottom wall due to suction. Furthermore, the fluid to be processed that has been subjected to the shearing action in the outermost annular channel is further subjected to an impact by the rotating body in the upper space portion, and further refinement is promoted.

The rotating body is provided with one or a plurality of rotating bodies in a vertical, diagonal, or horizontal orientation, or a combination thereof, and a high-speed rotation suitable for the size of a cylindrical container that is made according to the amount of fluid to be processed. Can be arranged.
The rotating body is configured by attaching a large number of blades and pins to a rotating plate. When the rotating body is opposed to a fixed body provided with fixed blades and fixed pins facing the blades and pins, the rotating body is covered by the opposed blades and pins. The processing fluid is subjected to combined mechanical forces such as a shearing action, an impact action, and a cavitation action, so that the ultrafine processing is promoted.
Further, the rotating body is disposed so as to be rotationally driven in the upper part of the cylindrical container or in the upper part of the casing, so that the rotating body is in a gas-liquid mixed state where the resistance to rotation is relatively low. High-speed rotation can be performed with a small amount of power, a large impact force can be applied to the flake-like organic matter in the fluid, and further ultra-miniaturization can be promoted. In addition, since the discharge means has a discharge port at the level of the rotating body, the fluid level inside the casing can be maintained substantially at the discharge port level, and the fluid to be treated can be brought into contact with the rotating body.

The jetting means is composed of a spiral pump and an ejector unit, and ultrafine organic materials can be achieved without requiring an expensive pump such as a high-pressure pump. In addition, since the ejector portion has an air suction portion for sucking air, a large amount of air can be contained in a fluid such as water, and a strong cavitation action can be combined with a shearing action or an impact action. Refinement can be promoted, and aerobic bacteria can be significantly activated in the downstream aeration tank to significantly increase the organic matter processing capacity.

In the upper part in the cylindrical container 350, specifically, a jet pump P2 such as a spiral pump or the like, specifically, at an interval 355 above the inner cylindrical body 353, the annular flow path 352 is rotated by rotating at a high speed of, for example, about 1000 rpm. And a rotating body 230 that impacts the rising flake sludge / organic matter in the water to be treated and makes it ultra fine to a few micron level.Also in the internal flow path 356, since the water to be treated is sucked from the bottom by the jet pump P2, the bottom plate 351b collides, and the flaky sludge in the water to be treated is made ultrafine by impact and cavitation such as a waterfall effect. The dam structure part of the connection part of the discharge pipe 362 is the same as that of the representative embodiment. Further, the same ejector section (not shown) as that of the above representative embodiment is provided.

The solubilizers 200 and (300) are in a steady operation state when the amount of water to be treated supplied from the supply pipes 221 and (361) becomes equal to the discharge amount discharged from the discharge pipes 222 and (362). Become. When the supply amount and the discharge amount are increased with respect to the constant volume of the inner cylindrical body 213, (353), the number of repetitions of the treated water passing through the injection pump P2 and being repeatedly subjected to the ultrafine action is reduced and the degree of superfineness is reduced. On the other hand, when the supply amount and the discharge amount are reduced, the number of repetitions of the treated water passing through the injection pump P2 and being repeatedly subjected to the ultrafine action increases, and the degree of ultrafineness is increased. Therefore, it is important to set the supply amount and the discharge amount with respect to a constant volume of the inner cylindrical body 213, (353). In the implementation test of the inventor, a flow meter is provided after the injection pump P2 to measure the total flow rate of repeated passages within several predetermined times, and the total flow rate is measured at a constant volume of the inner cylindrical body 213, (353). Divide and calculate the number of passes repeatedly, for example, observe the state of the water to be treated at 150 passes, 300 passes, and 1000 passes, and determine the best pass number. The best condition is obtained after 300 passes, the flake sludge is well refined and melts without separation of water and ultrafine sludge even if left for 24 hours. The number of surviving Escherichia coli and other bacteria active in biodegradation was the largest from 20 ° C to 45 ° C. By the way, water and ultrafine sludge are separated when left for 24 hours at 150 passes, and the degree of ultrafineness is insufficient. Although the sludge is not separated, the temperature rises to 52 ° C, and the number of surviving Escherichia coli is drastically reduced along with the ultrafine action, and the number of surviving other bacteria is also reduced. bad. Accordingly, the capacity of the injection pump P2 and the volume of the inner cylindrical body 213, (353) are determined so that the sample ultrafine state obtained in the number of passes from 200 to 300 can be achieved. The supply amount (discharge amount) of water to be treated is determined. Incidentally, in the solubilization apparatuses 200 and 300, the high-speed water flow speed is preferably 30 m / sec, and the relationship between the rotational speed 230 of the rotating body obtained by the number of times of passing 300 and the degree of micronization to the micron level is shown in FIG. The degree of fineness is considered to be proportional to the momentum (mv ² ) of the rotating body 230, that is, to the square of the speed.
