Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifying device for purifying pond water such as a fountain pond, a moat, a culture pond, a discharge channel, a hydrophilic river, other lakes and natural ponds.

[0002]

2. Description of the Related Art Conventionally, water in lakes, ponds, moats, etc. has impaired the growth of aerobic microorganisms due to the deterioration of bottom sediment due to the decomposition and alteration of sludge and organic matter, and the abnormal growth of algae. It is also generated, and anaerobic decomposition also occurs, which is likely to cause a bad odor. As a water purification apparatus for pond water, for example, a pressure sand filter is used, and it is known to circulate and filter pond water to purify the water quality. It is also known that oxidization and aeration treatments that utilize the self-cleaning action, which maintains aerobic conditions and is naturally purified by the photosynthesis of algae when exposed to sunlight, are also effective. There is.

[0003]

However, since lakes, swamps, pond water, etc. contain a relatively large amount of buoyant substances, the pressure type sand filter is extremely clogged with sand layers, etc. Must be done often, and BO in water
The removal of D etc. is not performed satisfactorily, and even in the case of utilizing natural self-cleaning action, aerobic microorganisms use oxygen generated as a result of algae's photosynthesis to oxidize and decompose BOD, while algae do not oxidize. Since carbon dioxide, a product of decomposition, is used for photosynthesis, abnormal generation of algae occurs, imbalance between aerobic microorganisms and algae causes imbalance, and dead carcasses of algae and decay of organic matter. As a result, there was a problem that the bottom sediment could not be reformed and that it was not possible to expect satisfactory water purification. The present invention eliminates these conventional drawbacks, purifies water by the power of aerobic microorganisms, humifies sludge as well as circulates and purifies whole lake water, promotes the reproduction of aerobic microorganisms, and causes abnormal growth of algae. It is an object of the present invention to provide a water purification apparatus that can be mitigated to promote a symbiotic action of both in a well-balanced manner and also to remove an offensive odor.

[0004]

Means for Solving the Problems The present invention relates to an upper open donut-shaped tubular body, a reservoir water portion, a packed layer of active humic substance communicating with the reservoir water portion, a packed layer of a microorganism holding carrier, and water collection. And a float portion in the tubular body, a sprinkler in the center of the doughnut-shaped tubular body, and a pumping mechanism including a fixed or retractable pumping conduit portion.

[0005]

[Function] The open upper cylinder is floated above the lake or pond water at the float, and the pond water inside the reservoir and other water surfaces is naturally or forcibly maintained under aerobic conditions and exposed to sunlight. Irradiation has been performed and natural purifying action is being carried out.However, part of this pond water, etc. is taken from the water intake part to the pumping conduit part, and the water pumped up into the air along the guide installed at the top. While being blown up and in contact with air, oxygen was entrained and dropped onto the stored water portion before flowing out to the packed bed portion, while the active humic material gradually dissolved in water while passing through the packed bed of granular active humic material, The water is collected in the water collection section and circulated from the return route into pond water, etc., and aerobic microorganisms in the pond water etc. are dissolved by the active humic substances to promote the reproduction by the microorganism-retaining carrier, and BOD removal and other effective Biologically treated, algae in pond water etc. Not observed abnormal proliferation of the aerobic microorganisms and effective cleaning action without symbiotic action is the inhibition of algae is performed, odor removal is facilitated by addition humic substances. Further, in the packed bed of the microorganism-retaining carrier formed under the granular packed bed of the active humic substance in the open type cylinder, the biological treatment is further promoted by the action of the microorganisms that are held and circulated in the circulation such as pond water. Part of the purified water and the sludge separated from the microorganism-holding carrier returns directly to the pumping conduit section through the water collecting section and returns to the pumping conduit section for recycling and reuse. By passing the pond water through the active humic substance in this way, the water is purified by the force of microorganisms, and the flocs that have grown at the same time are purified while floating in the lake, and the flocs that have settled humify the sludge and circulate throughout the lake. It can be purified.
