Abstract

<P>PROBLEM TO BE SOLVED: To aim at keeping water clean without giving someone any trouble though water in a water tank turns dirty by excrement of fishes which enters it. <P>SOLUTION: When many filters including limestone to be a filtering member are directly placed in the water tank and sewage is circulated by a submerged pump provided on the top of the filter, bacteria generate on limestone in the filter. An organic substance in the water tank is decomposed by the bacteria, thereby enabling water to be naturally kept clean. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a device for purifying sewage by installing a filter with a submerged pump containing a filter medium in a water tank, and a filter to be used.

  Conventional filtration devices include those in which a filtration tank is divided into three stages with a perforated plate, and those in which a sponge rotating body is attached so that a bacteria bed can be left separately even when the filter is replaced.

  Hereinafter, a conventional filtration device will be described with reference to FIGS. 1, 2, 3, and 4.

[Patent Document 1] Japanese Patent Application Laid-Open No. 08-205707 (FIG. 1)
The filtration tank set in the upper part of the water tank is divided into three stages by upper and lower perforated plates, and the water in the water tank can be efficiently filtered from the unstable time before the bacterial propagation at the beginning of the filtration device installation.

[Patent Document 2] Japanese Patent Laid-Open No. 10-192877 (FIG. 2)
A filtration device that integrates a filtration chamber containing a filter medium for aerobic bacteria and a septic tank containing a filler for anaerobic bacteria to reliably decompose organic substances in the water, Can be removed.

[Patent Document 3] Japanese Patent Laid-Open No. 2003-200011 (FIG. 3)
A mineral that is indispensable for the growth of bacteria can be stably supplied with a filter mat made by mixing minerals into powder and an adhesive.

[Patent Document 4] JP-A-2005-52699 (FIG. 4)
This is a filter that can leave the bacterial bed separately even if the bacterial species beneficial to biological filtration attached to the filter is discarded when the filter is replaced using a sponge rotating body.

In the conventional filtration apparatus, there was no effective filter medium as a bacteria generator.
Moreover, even if bacteria can be generated by passing sewage through the filtration device, passing water from the top to the bottom would quickly clog the filth and necessitate cleaning several times.

  In the present invention, first, research was conducted on what is a filter medium that easily generates bacteria for decomposing organic matter and purifying sewage.

  And it has been proved by repeated experiments that the best filter medium is limestone.

The sewage passes through the limestone gathering from the bottom to the top so that the water is not clogged.
In the pre-bacterial stage, experiments have also demonstrated that the filter media acts as a filter and then shifts to the bacterial generation necessary for organic matter degradation.

  In the present invention, by installing a filter using limestone directly in the water tank, the water circulation is accelerated and the organic matter is rapidly decomposed by bacteria.

  At the same time, the filtered water is immediately returned to the aquarium along with the air to supply oxygen, and as a result of the experiment, the glass surface does not become dirty and the water does not become cloudy even in summer. Mineral content comes to be generated.

  Therefore, there is almost no need for cleaning, and the above problems have been solved.

  According to the present invention, replenishment is necessary for the amount of water in the aquarium that is reduced due to evaporation or the like, but there is almost no need for water replacement and cleaning.

  Conventionally, the water temperature changed by replacing the water, and the fish that was put in was weakened in the present invention, limestone not only generates bacteria, but also calcium carbonate that dissolves in a trace amount Work will make you more energetic.

  In the present invention, the water in the filter (4) is pumped out by the action of the submersible pump (1) provided in the upper part of the filter (4), and blown out from the pipe (2) toward the water. .

  At the same time, because the water is pumped out of the filter (4), it tries to keep the water level. From the slight gap at the bottom of the filter, it sucks up the sewage from the surrounding fish excrement and uneaten food. Give me.

  As the above circulation is repeated, substances that were initially trapped as mere filth in the limestone (3) will generate bacteria that decompose the organic matter, which is the filth, and will fully purify water. Is done.

Claims (2)

  Passing sewage from the bottom to the top through a filter chamber containing limestone as filter material. Bacteria naturally occur around the limestone. A filter that purifies water by decomposing organic matter that is the source of sewage by the bacteria.   A filter containing limestone according to claim 1 is directly attached to the aquarium, and a submersible pump is attached to the upper part, and the bottom part is in a net state so that a slight gap can be formed between the bottom of the aquarium when installed. Installed filtration device.
