Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a useful microorganism discharge device for releasing useful microorganisms into water such as rivers, swamps, ponds, lakes, inland seas (hereinafter simply referred to as rivers), and particularly rivers. The present invention relates to a useful microbial discharge device suitable for use in a river purification system capable of purifying water and preventing eutrophication.

2. Description of the Related Art In recent years, there has been a strong call for environmental protection, and along with this, the prevention of pollution of inland seas, lakes and marshes and rivers
National efforts such as enactment of the Water Pollution Control Law have resulted in remarkable effects such as improvement of water quality transparency. Among these, unfortunately, there are still no effective means for preventing eutrophication, especially for economical removal of nitrogen and phosphoric acid. This is a situation that can only be achieved by purification.

For the purification of such wastewater, it has been already known that the purpose of removing nitrogen and phosphoric acid has been achieved by using a commercially available combined treatment septic tank and a commercially available useful microorganism in combination. This useful microorganism has already been on the market since the 1955's, and is supported by municipalities for the purpose of effective use such as prevention of foul odors in toilets, elimination of clogging in wastewater drainage pipes, and conversion of human waste and excrement of livestock into organic fertilizers. The rice has been expanded, and in recent years, it has been especially used to eliminate the bad odor of livestock pollution, and to be used for groundbreaking purification of dirty wastewater with a simple filter bed purification device, which is remarkable for preventing environmental degradation. It has a proven track record.

As other conventional techniques, there are already known ones that use natural microorganisms to achieve the purpose in general septic tanks and public sewer final treatment plants, and in some cases, It is actually used.

[0005]

However, in the conventional treatment equipment and purification equipment, a large amount of nitrogen and phosphoric acid for preventing pollution of inflowing rivers into inland seas and lakes is required. It was not possible to remove the components and prevent eutrophication. In particular, in purification equipment for wastewater that flows into the inland sea and lakes, there are still problems in removing nitrogen and phosphoric acid, and sludge treatment, and along with dust treatment, there is a clog for improving the environment. Such a problem places a heavy burden on the public municipality beyond its ability to cope with it, and thus requires an urgent solution and the construction of a next-generation purification system.

In view of such problems in the prior art, the same applicant as the present application removes a large amount of nitrogen and phosphoric acid in order to prevent pollution by rivers flowing into the inland sea and lakes. As a river purification system capable of preventing eutrophication and eutrophication, there has already been proposed a system in which useful microorganisms such as tetrabacillus are released into the flowing water of a river, and oxidatively decomposed and filtered.

It is an object of the present invention to provide a useful microorganism discharge device for discharging useful microorganisms into the flowing water of a river, which is particularly suitable for use in the river purification system described above.

[0008]

In order to achieve the above object, the present invention provides a useful microorganism discharge device for discharging useful microorganisms supplied from a useful microorganism water supply source to wastewater such as rivers. , A float arranged on the surface of water such as a river, a discharge pipe attached to the float, and a plurality of useful microbial waters connected to the side wall of the discharge pipe and supplied from the useful microbial water supply source to the discharge pipe. Disclosed is a discharge device for useful microorganisms, characterized by comprising a discharge tube for separating the discharge water into a plurality of waste water and discharging it into wastewater such as a river, and a lifting mechanism for pulling up the discharge device as a whole from the river when the river overflows abnormally.

[0009]

According to the above-mentioned useful microorganism discharge device, the discharge pipe can be freely arranged on the water surface of a river or the like by the float, and the discharge pipe is discharged through plural discharge tubes taken out from the discharge pipe. , It becomes possible to effectively release useful microbial water into wastewater such as rivers,
Therefore, it is possible to prevent eutrophication of water in rivers and the like, and prevent pollution of water quality in the inland sea and lakes.

The function of this tetrabacillus is that in rivers containing sewage, there are few microorganisms that positively contribute to the decomposition of organic matter, so adding this to the river increases the number of microorganisms and protozoa living in the sewage. It will be. This increases the number of microorganisms that are the basis of the food chain, thickens the chain of the food chain, increases the number of protozoa / plankton, etc., and promotes the self-cleaning action of the river.

As described above, the increase of microorganisms by addition of tetrabacillus means that decomposition of organic matter is promoted, pH environment of water is adjusted, and abnormal occurrence of phytoplankton such as water-bloom is suppressed.
