Description

Lake water purification treatment system and apparatus

The present invention relates to a lake water purification treatment system and apparatus for preventing the decay of water due to lack of oxygen by removing foreign substances or contaminants introduced in the lake or pond.

In the past, aeration tanks were installed in the water, and only the water was sprayed.

Therefore, deciduous and debris around the lake, pond, or naturally formed lake, pond, and swamp in the artificially formed golf course are introduced into the water, causing sedimentation, decay, oxygen deficiency due to the identity of the water, and spraying on the grass around the lake. As fertilizers (nitrogen and phosphorus) and organic medicines gradually accumulate, they enter the water and become nutrients necessary for the reproduction of lower organisms that pollute the water. When the water becomes eutrophic, water decays due to lack of oxygen, oxygen-free microorganisms such as green algae thrive, and there is a problem such that water becomes odorous and loses self-cleaning ability.

The present invention has been made to solve the above problems, to form a flow to circulate the entire stagnant lake water and to increase the dissolved oxygen by injecting mixed air into the water to have the midnight power of the water, The purified water is discharged into the lake water by inhaling and filtering the suspended solids and sediments, and the filtered foreign substances and contaminants are removed to the outside of the lake water.In the case of green algae, a flocculant is added to the lake water to aggregate green algae or suspended matter. After the air bubbles are generated, flocculation flops (FLOCK) are floated on the surface of the water, and floating flops such as flotation flocs are collected and removed from the lake water to be configured to purify foreign substances or contaminants in the lake water.

Referring to the configuration and operation of the present invention in detail based on the accompanying drawings as follows.

A plurality of submersible mixers 2 or submersible pumps 2 'are installed at the bottom of the lake water 1 so as to form a flow such that the whole of the purified lake water 1 is circulated at a proper flow rate in a constant direction. The bubble generator (3) which increases the dissolved oxygen by injecting the mixed air to increase the dissolved oxygen, and has a self-cleaning ability of water, and the chemical metering pump (4) which inputs flocculant when a large amount of green algae is generated, the bottom surface of the appeal water (1) It is connected to the outside and installed, the circulation pump (5) to filter the water is installed between the fiber trap (FIBER TRAP) (6) and the filter (7) outside the lake water (1) ) A plurality of intake ports 8 are provided on the bottom surface to connect the bottom of the lake water (1) to the bottom of the lake. The embedded hose hose 9 is connected to the fiber trap 6, and the lake water (1) bottom or the side surface thereof. A plurality of outlet hoses 9 'having a plurality of discharge ports 10 and 10' 9) is connected to the filter (7), the operation of the circulating pump (5) when the turbid water and suspended matter flows through the flow hose (9) with a suction port (8), the leaves falling in the pre-filtration process, Grass and other foreign matter are first filtered out of the fiber trap (6), and turbid water or suspended matter in the lake water (1), debris from dead algae, and sediment are filtered by the filter (7). A plurality of discharge ports 10 and 10 'are discharged to the appealing water 1 through the switches 9' and 9, and the filtered foreign matter or contaminants are removed to the waste treatment plant 14 outside the appealing water 1. .

When a green algae occurs, a coagulant is introduced into the chemical metering pump 4 to agglomerate algae or suspended matter, and then by micro bubbles generated in the microbubble generating device 11 connected to the bottom of the lake water (1). The aggregates are collected finely to form a flocculated flocculation flocculated to float on the surface of the water, and the flotations such as flocculated flotations are collected by installing a flotation bolt (12) on the surface of the floc and then collected by the waste recovery apparatus (13). The present invention relates to a lake water purification treatment system and apparatus, which is configured to be removed to an external waste treatment plant.

According to the present invention, the stagnant lake water (1) is rotated by the water mixer (2) or the water pump (2 ') to circulate, thereby suppressing the decay and suspension of algae breeding in the water and generating bubbles. By supplying oxygen to the water by the device (3), the oxygen deficiency phenomenon due to the identity of the water and contaminants are introduced to prevent the reproduction of lower organisms and microorganisms that do not need oxygen to prevent the decay of water, circulation pump (5 ) And filter out the fallen leaves and foreign substances introduced into the water by the filtration device consisting of the fiber trap (6) and the filter (7), and discharges only the filtered purified water to the lake water (1) to maintain a clean lake water (1) If a large amount of green algae occurs or a large amount of green algae occurs during the rainy season in summer, a coagulant is introduced into the chemical metering pump (4) to coagulate green algae or suspended matter, and then to generate microbubbles. By generating micro-bubbles with the device 11 to float floating matters such as flocculation flocks on the water surface, foreign matters or contaminants can be recovered and processed regardless of the season, and the flocculated flotation flocks and flocculation flocs are collected by the flotation fence 12. After collecting them at the recovery site, the waste collection device 13 removes them in the sewage treatment plant 14 where they are not visible to the outside of the appeal water 1 so that the foreign substances or contaminants of the appeal water 1 are purified and cleaned. It is characterized by being kept in (1).

The present invention of the above configuration is installed in a golf course lake or pond, etc., to prevent the corruption of water, to have a self-cleaning ability to always maintain a clear and clean lake water, fish can inhabit, can be used as a fishing ground, green algae phenomenon It can contribute to the improvement of environmental pollution such as prevention, and it is possible to remove foreign substances or pollutants by simply operating the device whenever necessary regardless of the season. If the contamination is not serious, it is possible to provide an effect such as purification can be performed only by the dotted line process of FIG.
