The present invention relates to a high water treatment method, such as sewage and livestock wastewater, more specifically, the oxygen aeration performed in the water treatment facility, etc. as the importance of agitation, and the sludge accumulated in the lower part is stirred by the method of aeration to the top and stirred Organic materials and SS and phosphorus are stirred and provided to the contact medium of the fixed phase microorganism, and the aeration tank and the surface area of the media are large, maximizing the activation of microbial reproduction, and thus causing a process to decompose and remove the contaminants by living organisms. And by providing additional oxygen generator and microbubble generator, the maximum contact time is decomposed and removed at the stage of aeration tank, that is, by treating with microbubbles that are not easily floated, the area of contact between water and oxygen to be treated. And altitude numbers that can increase oxidation time by lengthening contact time It relates to the way Lee.

In addition, the aeration method that provides only oxygen in the aeration tank is a method that decomposes and removes the contaminant material by washing sludge and filamentous bacteria accumulated in the fixed-phase microorganism contact medium and transporting it back to the settling tank. It relates to a high water treatment method of a facility that can be purified, sterilized and reused.

In general, the efficiency of eliminating the causative substances while relying on aerobic microbial treatment was low, and the efficiency of the anaerobic treatment was maximized by applying the anaerobic treatment method to the problem of excessive maintenance costs in the treatment method by additional facilities. Although there are difficulties in terms of conditions and conditions, activation of anaerobic bacteria can effectively digest and decompose causative agents compared to conventional treatments, and the residence time is important in the anaerobic tank of influent.

Therefore, this system can solve many problems compared to existing facilities because the system basically decomposes and removes the pollutant by biological reaction.

In such a situation, it is an important technology that can economically and efficiently remove pollutants, ensure safe water quality, and fundamentally significantly reduce secondary treatment and pollution depending on the post-treatment of sludge.

The present invention may be referred to as research and development for solving many of the conventional problems as described above.

That is, it effectively provides micro bubbles to sewage, sewage, and manure discharged from homes and toilets, decomposes and digests the causative substances such as organic substances in the water to be treated, and maximizes the treatment efficiency in the decomposition tank by aerobic bacteria. And practical use of highly efficient purification facilities and equipment.

In addition, the present invention realized the space of the aeration tank as the space for activating the maximum microorganisms and by minimizing the occurrence of filamentous fungi by incorporating the equipment of agitation so that the organic matter can be efficiently provided according to the activation of the microorganisms and the organic matters are decomposed and removed. With the emphasis on activating aerobic and anaerobic bacteria, the fine particles of phosphorus and other causative agents are realized as practical water treatment facilities equipped to separate and reprocess by microbubbles and contact media.

In order to achieve the above object, the present invention has the following features.

First, a microbubble device (ⓗ) is provided and brought into contact with the aeration tank to oxidize and promote the organic matter in the water to be treated close to 100%, thereby greatly reducing the processing time in the decomposition tank by aerobic bacteria provided thereafter.

Second, in addition to supplying high concentrations of ozone, the supply of ozone bubbles increases the contact area and the contact time with the water to be treated in particular. The purpose of maximizing efficiency such as water purification and decomposition of harmful substances is achieved. The microbubble device ⓗ is a piping installation type that takes up almost no place, and the device can be put to practical use.

Third, the fixed bed microorganism contact medium has been applied in the existing method, but the lack of a response to the inefficiency of the operation and the water quality deteriorates over time due to the problem of the accumulated sludge does not solve the problem in the back washing tube (ⓓ ), And the structure to increase the surface area of the microbial contact medium and the vertical strip which is easy to clean the accumulated sludge can be cleaned in a small amount of oxygen.

Fourth, the treatment target water highly treated by the present invention was installed a sterilization treatment device to be purified to the highest level or more and the final sterilization using ozone rather than the conventional chemical method to remove turbidity and odor remaining in the water quality Treated and purified water is useful for toilets and other agricultural water.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described according to an accompanying drawing.

First, the micro-bubble tank 19 is to infiltrate the water to be treated, such as manure or mixed wastewater, to oxidize as much as possible by the micro-bubble, anaerobic tank is a micro-bubble tank (⑧) by the anaerobic bacteria to the organic material in the water to be treated is not completely oxidized It is to promote oxidation. The inner structure of the aeration tank (⑥⑦⑪) is composed of a plurality of threads provided with a plurality of partition walls by a boundary plate, and fills the contact media to enhance the function of microbial activity to provide a suitable living place for bacteria in each chamber and to the treated water media Each thread is passed up and down to make contact.

In front of the micro-bubble tank (8), a tank for hydrolyzing the solid content of the polymer into low molecules may be provided.

The broa sends air for generating microbubbles to the mixing pump, and the mixing pump mixes the water from the sterilization tank (⑨) with the final treatment to generate the microbubbles, and at the same time, the microbubble generating device. The pressure is applied to (ⓗ).

The microbubble generating device (ⓗ) is to generate a fine bubble to be installed in the pipe, the water supply pipe tap water until the treated water flowed into the microbubble tank (⑧) is finally treated by the sterilization treatment tank (⑨) to supply water Or industrial water.

The anaerobic sedimentation tank (⑩) is installed in front of the aeration tank (⑥⑦⑪) and behind the microbubble tank (⑧), which can remove nitrogen or phosphorus above the environmental standard of the water to be treated.

In addition, the micro-bubble generating device (ⓗ) is a device for generating micro-bubbles through the rotation of the rotating plate is formed in a plurality of perforated nets on the lower surface while rotating inside the cylindrical.

The sterilization tank (⑨) maintains the water to be treated in contact with ozone for a certain period of time, which makes it possible to make ozone stronger, decompose harmful substances, deodorize and bleach, and to dissolve it in a constant concentration in the water. Decompose the ozone.

Here, the most appropriate conditions of media and micro-bubble, in which the aerobic and anaerobic bacteria decompose and remove the contaminants in the treatment tank, are applied to the system. It is a system that prevents sludge from accumulating in aeration method and provides agitation of organic materials to contact media to facilitate bacteria production and reproduction.

As described in detail above, in the present invention, the contact area and the contact time with the water to be treated in the septic tank or the like perform oxygen aeration due to microbubbles, so that the organic matter in the water can be catalytically oxidized to the limit within a short time. Therefore, the practical use of the equipment by high efficiency can be realized.

In addition, the secondary treatment cost can be reduced by radically decomposing and removing the causative agent of the pollutant by a biological reaction.

In addition, by treating the pollutant of the water quality to ensure the best water quality can be reused in the toilet water, agricultural water, and other garden water.
