- FIG. 2 is an explanatory diagram showing an outline of a water treatment system in which a treatment tank for releasing fish according to the present invention is combined with an advanced treatment system for sewage.
- FIG. 3 is an explanatory view showing an outline of a water treatment system in which a treatment tank for releasing fish according to the present invention is combined with an advanced treatment system for sewage.
- FIG. 4 is a schematic diagram showing the structure of a simulation tank used in Example 3.
- the water treatment method of the present invention will be described in detail.
- various treatment systems for ordinary sewage facilities and food wastewater can be adopted. Nonetheless, equipment that poses a problem in the incorporation of small metazoans into treated water, such as advanced sewage treatment facilities for the purpose of reusing treated water, is particularly effective. That is, the present invention is applied to an advanced sewage treatment facility that intends to effectively use the treated water for flushing toilet water, sprinkling water, or landscape water for artificial ponds, artificial babbles, artificial waterfalls, and the like. Can apply power S.
- Examples of advanced sewage treatment include sedimentation treatment, biological treatment, activated sludge treatment, coagulation sedimentation treatment, biofilm filtration treatment, ozone treatment, and combinations thereof.
- S power In sewage and wastewater treatment systems some solid matter (sludge) accumulates at the bottom of the treated water tank, and micrometamorphous animals such as mosquito larvae and leeches are likely to occur in this area.
- sludge solid matter accumulates at the bottom of the treated water tank, and micrometamorphous animals such as mosquito larvae and leeches.
- specific species of mosquito larvae and leeches that are resistant to these treatments selectively survive, causing large outbreaks. I'm sorry.
- FIG. 1 shows the concept of a water treatment apparatus according to one embodiment of the present invention.
- the treated sewage water obtained by performing the various advanced treatments described above is introduced into a treated water tank where fish are released, and, depending on the case, is discharged after being filtered by a filter, or is called a so-called medium. It can be reused as water for washing, water for sprinkling, water for scenic landscape, various tap water, etc. in the form of waterways.
- fish are directly fed to a treated water tank into which treated water is introduced, and prey on micrometamorphous animals such as larvae and hills with slime power to suppress their generation and proliferation.
- micrometamorphous animals such as larvae and hills with slime power to suppress their generation and proliferation.
- omnivorous fish such as guppy, tilapia, koi, crucian carp, and loach are appropriate.
- oxygen supply equipment a pH adjustment mechanism, a temperature adjustment mechanism, and other equipment for maintaining an appropriate environment for fish to the treatment tank for releasing fish as necessary.
- Masire is desirable to add oxygen supply equipment, a pH adjustment mechanism, a temperature adjustment mechanism, and other equipment for maintaining an appropriate environment for fish to the treatment tank for releasing fish as necessary.
- the supply of light to a treatment tank for releasing fish is an important factor not only in favor of foraging during predation of fish but also for maintaining a good ecological rhythm of fish. It is preferable to maintain the activity of fish by installing a window for lighting and / or installing a lighting system and running a timer to give a light rhythm similar to day and night in nature. Depending on the type of fish to be released, it is effective to use a special light source such as near infrared rays. In this way, the fish feed on microsurvivors such as mosquito larvae and leech by preparing the surviving environment of the fishes and releasing them, thereby generating micro metamorphic animals such as larvae of mossel and hills. Proliferation is deterred.
- micro metazoans such as larvae and leeches of the midge, or the properties of sludge mixed in the aquarium
- the important thing here is that This is the amount of fish released based on the amount of micro metazoan animals such as squirrel larvae and leech, and the amount of organic sludge.
- the amount of micro metazoan such as hills and organic sludge is preferably 5 to 200 g, more preferably 20 to 70 g as dry weight. If the amount of small metazoans and organic sludge to be fed is less than 5 g as dry weight per day per 1 kg of fish body weight, the fish will starve and it will be difficult to survive continuously.
- the relationship between the amount of micro metazoans such as mosquito larvae and organic sludge flowing into the treated water tank and the amount of fish to be released is determined by the fish weight.
- the fish density in the aquarium to be released is also an important point, but this depends on the amount of bait (sludge etc.) supplied. It is possible to calculate the amount of fish to be released so that it falls within the above range.
- the treated water in the treated water tank is guided to a filter, and the effluent from the water tank from which the fish have been released is included in the effluent from the turtle.
- Figs. 2 and 3 show the concept of a form in which the treatment tank for releasing fish according to the present invention is combined with an advanced sewage treatment system.
- sewage is treated by an advanced treatment system that performs sedimentation treatment, activated sludge treatment, biofilm filtration treatment, ozone treatment, and, in some cases, filtration treatment and chlorination treatment in this order.
- the resulting treated water generally has an SS power of 2 g / mL or less-6 mg / L, pH of 5.8.8.6, COD of 1 mg / L or less-8 mg / L, and BOD of 3 mg / L or less-6 mg.
- sewage is treated by an advanced treatment system that performs sedimentation treatment, activated sludge treatment, coagulation sedimentation treatment, ozone treatment, filtration treatment, and, in some cases, chlorination treatment in this order.
- the resulting treated water generally has an SS of 0.2g / mL or less-6mg, a pH of 5.8-8.6, a COD of lmg / L or less-8mg / L, and a BOD of 3mg / L or less-6mg.
- This is introduced into a treated water tank where fish that have been used in the present invention have been released, and then, if necessary, after passing through a filter, or discharged, or used for washing water, sprinkling water, scenic water, etc.
- Example 1 To be reused as Example 1
