Description

The present invention relates to a water purification device that purifies water by immersing it in a river, pond, pool or the like.

Conventionally, various devices for purifying water have been developed. As a device using aerobic microorganisms and anaerobic microorganisms, aerobic microorganisms can be installed at different locations in a continuous water channel by connecting narrow and narrow cylindrical water channels. Water purifiers that decompose organic substances by coexisting an area where anaerobic microorganisms are present and water sequentially pumped through each water channel have been developed (for example, Patent Document 1).

However, in this device, a cylindrical unitized water channel is meandered and connected, and water is supplied to it by a pump, so that the device becomes large, requires a place for installing the device, and maintenance of the pump is troublesome. There were problems such as.
JP 2002-143887 A

This invention improves the said problem, and provides the water purification apparatus which can purify water stably over a long period of time only by being immersed in water, such as a river, a pool, and a pond.

In the water purification apparatus according to claim 1 of the present invention, both ends of a mesh cylindrical body wound with a mesh are closed with a cover plate, a sponge is wound cylindrically inside the mesh cylindrical body, and further a ceramic ceramic is wound inside the mesh cylindrical body. It is characterized in that it is filled with a zygote and zeolite, impregnated with aerobic microorganisms and anaerobic microorganisms, and immersed in water for use.

The water purification apparatus according to claim 2 of the present invention is the water purification apparatus according to claim 1, wherein natural ceramics and charcoal are further mixed into the ceramic sintered body and zeolite.

According to the water purification apparatus of the first aspect of the present invention, the porous ceramic sintered body and the zeolite are impregnated with aerobic microorganisms and anaerobic microorganisms, and this is where microorganisms live and is contained in water. Ceramic sintered body and zeolite, which decomposes organic matter and impregnated with microorganisms, are held in a water-permeable mesh-like cylindrical body and sponge to prevent run-off and maintain a stable purification action over a long period of time. Can do.

Further, according to the water purification apparatus of claim 2, by further mixing natural stone or charcoal with the ceramic sintered body and zeolite, the natural stone plays a role of securing a flow path of water, so that water is smoothly supplied. It can flow inside and promote the purification action by microorganisms. Charcoal is porous and has excellent adsorptivity, and is excellent in the adsorption and deodorization of harmful substances.

A water purification device that can be immersed in water to purify water has been realized.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. In FIG. 1, reference numeral 1 denotes a water purification device. As shown in FIG. 2, both ends of a mesh cylinder 2 wound with a plastic mesh are closed with stainless lid plates 3 and 3, and the mesh cylinder 2 is further closed. A sponge 4 is wound in a cylindrical shape inside, and a ceramic sintered body 5, zeolite 6, natural stone 7 and charcoal 8 are filled inside, and an aerobic microorganism and an anaerobic microorganism (for example, EM fungus) are filled therein. Is impregnated. In this case, the particle size of the ceramic sintered body 5 to be filled, the zeolite 6, the natural stone 7 and the charcoal 8 is preferably about 5 to 20 mm. For example, as shown in FIG. 3, a plurality of water purification apparatuses 1 are immersed in a shallow water in a dirty river 9 and fixed with a rope 10 so as not to be lost.

If the water purification device 1 is immersed in the river 8 and left as described above, the water of the dirty river 9 flows into the inside through the sponge 4 from the mesh cylindrical body 2, and the organic matter contained in the water is baked into the ceramic. It is decomposed and purified by aerobic microorganisms and anaerobic microorganisms impregnated in the aggregate 5 and zeolite 6. In this case, the ceramic sintered body 5 is porous and can live as a microorganism, and can maintain the purification action for a long period of time. When the ceramic sintered body 5 is mixed with ceramic powder and mixed with water containing aerobic microorganisms and anaerobic microorganisms, the ceramic itself retains the microorganisms and can further improve the effect.

Similarly, the zeolite 6 is porous and becomes a resident of microorganisms and maintains the purification action for a long period of time. It is less likely to be clogged than the ceramic sintered body 5 and is inexpensive. Moreover, the natural stone 7 plays a role of securing a flow path of water, and water can smoothly flow through the inside to promote a purification action by microorganisms. Further, the charcoal 8 is porous and has excellent adsorptivity, and is excellent in adsorption of harmful substances and deodorizing action.

Further, the net-like cylindrical body 2 and the sponge 4 are water-permeable, and the ceramic sintered body 5 filled with the zeolite 6, the zeolite 6, the natural stone 7 and the charcoal 8 are retained to prevent the loss, and the purification action is performed over a long period of time. Can be held. Further, when the effect has been reduced with the water purification device 1 immersed, it is preferable to sprinkle the water purification device 1 with the aerobic microorganisms and the anaerobic microorganisms for impregnation.

As a result of water quality tests in the Tonosugawa and Kamiitabashi districts of Iwaki City, Fukushima Prefecture, the number of E. coli was 24,000, total nitrogen was 2.20, and total phosphorus was 0.055. The water purification apparatus 1 of this invention was installed in this river, and after 2 weeks, the water quality test was performed again to confirm the effect. As a result, the number of Escherichia coli decreased to 4,900, total nitrogen 1.90 and total phosphorus 0.042, and the transparency was improved, and the effect of the present invention could be confirmed.

In addition, the water purification device 1 was installed in the corner of the Funabiki Junior High School pool in Tamura-gun, Fukushima Prefecture to purify the water in the pool. The test was conducted 4 times during 2 months of use of the pool. As a result, none of the coliforms were detected, the general bacteria were 0, and the turbidity was less than 0.5 degree.

In the above description, the case where a plastic net is used as the net-like cylindrical body 2 is shown, but a non-rusting metal net such as stainless steel may be used. The lid plate 3 is not limited to stainless steel but may be plastic.

In the above description, the case of purifying the water quality of rivers and pools has been described. However, the present invention can be widely applied to purification of ponds, swamps, factory wastewater, and the like.

It is a front view of the water purification apparatus by the Example of this invention. It is sectional drawing which shows the water purification apparatus of FIG. It is a perspective view which shows the case where the water purification apparatus of FIG. 1 is installed in the river.
