Dew. In other words, the African frog is a medium-sized larva native to South Africa, and was given this name because it has predatory claws on its hind limbs.The official scientific name is ``Xenopus'', and it Unlike the elms that breed once per season, they lay eggs throughout the year regardless of the season, and egg-laying can be artificially promoted by injecting hormones into the parent elms. o o.

は青粉の天敵であることが証明される。African frogs are herbivorous as larvae, but become carnivorous after turning into frogs. Although they are amphibious, they can be easily kept in an aquarium by feeding on rounded carcasses that live in groups in menstrual water. This larva, which can demonstrate its suitability as a laboratory animal, metamorphoses and grows into a baby frog in about 40 days after becoming a frog.
As mentioned above, the larvae are herbivorous, preferring to feed on blue powder and plankton in the water, and grow happily in polluted water that is clouded with blue powder. Therefore, if a small glass container is filled with blue powder waste water and an appropriate number of larvae are released, after a certain period of time the larvae will eat up the blue powder in the water and the water in the container will easily become transparent. This proves that the larvae prefer to prey on blue powder, and that these larvae are natural enemies of blue powder in the natural world.

必要時期を迎えていると云うべきである。On the other hand, blue powder is microscopic algae such as flagellates and 1L green algae that occur on the stagnant water surface of ponds and lakes.
As is known, it increases the amount of water in the water through its assimilation effect, and also serves as food for fish, but if it grows in large numbers and the concentration in the water becomes too high, it will cause too much oxygen, which actually inhibits the respiration of fish. The dead green powder acts as a source of pollution, emitting evil effects, and becomes a source of pollution, especially in lakes and ponds near cities, where domestic wastewater flows in and becomes a source of nutrients, causing the blue powder to grow thickly and pollute the water. In addition to deteriorating the natural environment, this has a serious impact on the use of water resources for the many cities that depend on these lakes and marshes as water sources for drinking water. The blue powder floating in the water is small and large in quantity, making it difficult to filter, and water treatment using chlorine and activated carbon is not sufficiently effective, leaving residents troubled by deep tap water. There are concerns about the generation of carcinogenic trihalomethanes associated with water purification, and the removal of blue powder for the purpose of water purification is an urgent issue that requires damage prevention measures to be taken, and this must be resolved as soon as possible. It should be said that the time has come when it is necessary to do so.

ことにする。In the present invention, a volume of sewage from a lake or marsh is placed in a predetermined aquarium, and an appropriate number of African frog larvae are released into the tank according to the capacity to prey on blue powder, plankton, etc. in the sewage. The water purification process is carried out by removing blue powder etc. with the larvae and confirming that the pollution is clear, and then sending the purified water out of the tank. A preferred implementation is obtained and will be explained with reference to the drawings.

African frog larvae are released. Depending on the growth level of the larvae to be released, the amount of water per liter of water will be approximately 2. The water in the tank becomes transparent by feeding on the blue powder and plankton floating in it, and after confirming this state, the drain port 11 is opened, the drain pump 10 is activated, and the purified water is sent to the reservoir through the drain pipe 9. After the drainage is finished, pond water is injected again through the water inlet 8, and the water purification process is repeated by repeatedly removing blue powder caused by the larvae.In addition, a small amount of pond water is continuously poured in through the water inlet 8 to prevent water from facing the water. It is also possible to continuously drain the supernatant overflowing water from the drain port 11' opened in the wall at the same water level to the reservoir from the drain pipe 12.

The trap is collected and sent to a separately provided septic tank (not shown) through a drain pipe 3 by operating a drainage pump 10' from the drainage port 11'' of the basin, where it is purified by microorganisms.

もなる。Yokouchi larvae feed on blue powder in the water, grow, metamorphose, and become raw salmon, but if necessary, adjust the number of larvae released, and if metamorphosis occurs, prepare new larvae separately. This is done by draining the supernatant water in these holding tanks and collecting the frogs in the holding tank 4, and taking this opportunity to clean the inner bottom surface of the tank 111'. In addition, each pouring and draining port 8.11, 11
', 11'' should be equipped with a Fi open/close valve to operate according to the water supply and water, and a protective net 14.15 should be provided at each section and the top of the tank to prevent larvae and frogs from getting out of the tank. This prevents dissipation and invasion of foreign enemies.Furthermore, when implementing the JJ class, it is possible to increase the water temperature in the tank by placing heat insulating material such as vinyl on the top of the tank, and it is possible to increase the water temperature in the tank. Depending on the topography, a natural drop or a power pump will be applied, and an electric automatic device will be used to switch the injection and drainage during transparency measurement, in order to save labor and improve functionality. By putting sewage from a water source pond such as a lake into a designated water tank and releasing African frog larvae into the tank, the nitrogen and phosphorus in the sewage can be used as a source of fertilization to capture and purify the blue powder that breeds. Since L7 is a biological treatment, there is no secondary separation of carcinogenic substances that occur with chemical treatments such as JII, and it is easy to pour pond water into the aquarium and drain water after purification. By providing a basin in the center of the bottom of the tank, larval excrement and other sediment can be collected and purified using microorganisms, resulting in high purification efficiency.In addition, the larvae released in the tank can grow and grow. They metamorphose and become frogs, but because the aquarium is equipped with #i prevention #IIR, they will never escape outside the tank by themselves, and will return to nearby lakes and ponds, causing deterioration of the natural environment. On the contrary, the African frog was able to meet the valuable demand as an experimental animal and as a teaching material for science education, and not only contributed to sewage purification as a larva, but also became useful in science and science as a larva. They will also play the role of two islands with one stone, being valuable and socially useful.
