Description

Self-powered water purification device for stagnant water {WATER TREATMENT APPARATUS OF SELF POWER-GENERATION TYPE}

The present invention relates to a water purification device, and more particularly, to a self-powered water purification device for a stagnant body of water operated in a stagnant body of water, such as a dam or a lake.

To prevent the development of green algae centered on cyanobacteria in the lake, or to remove algae that have already been blooming, it is necessary to remove P or N components from the outside that can promote algae reproduction. In the case of lakes and reservoirs, it is a stagnant body with a long hydraulic retention time, which is the main cause of green algae, as well as pollutants such as nitrogen and phosphorus from the outside, but on the other hand, it is more and more algae in stagnant conditions with little water flow. Is the cause of promoting growth.

In addition, if the supply of dissolved oxygen and the flow of water can be provided, the growth of aerobic microorganisms that constituted other normal ecosystems in the water can be relatively accelerated, thereby accelerating the killing of algae and eliminating the dominant force. One example is the installation of an underwater aerator in a small pond to provide water flow and oxygen. Existing physicochemical methods (e.g. underwater aeration, chemical dosing, etc.) developed for lake purification require excessive management costs relative to the size of the lake and create sources of contaminants such as sediment formation on the lake bottom. Not only is it highly likely to provide, but if the lake itself is large, it is practically limited in applying these techniques to purify the lake. On the other hand, there is a lack of data on the treatment efficiency of the inflow of the lake and the water purification method that can be installed in the lake, and the effects of various water purification methods on the lake water quality improvement are insufficient. The aim is to develop technology.

Therefore, in order to solve the water quality problem of the lake, the proper aeration function, the flow of water, and the injection of chemicals can effectively improve the water quality. As mentioned above, the currently applied aeration due to the fountain or the water has a disadvantage in that it cannot be applied to a large lake because the energy cost is excessive and the amount of water actually aerated is small. In addition, the addition of coagulant in the lake is too expensive, and sediment is precipitated and accumulated on the bottom, and if it is anaerobic, nutrients are re-dissolved. Therefore, the aeration was installed in a highly efficient circulation type to maximize the surface of the bottom water exposed to the upper air, and the power required is a hybrid system using both solar and wind at the same time. It was not necessary. In the case of excessive amounts of nutrients in the lake water, natural coagulants or loess were added to coagulate, and the aerobic state was maintained in the lake so that young and salt salts such as nitrogen and phosphorus were not re-dissolved from the bottom of the lake.

Hybrid refers to the functional combination of two or more systems with each other to provide new functions. Hybrid equipment of alternative energy refers to a structure in which wind energy and solar energy are combined to obtain energy. By converting solar energy into electrical energy on sunny days and wind power into electrical energy on cloudy or rainy days, it complements the characteristics of solar energy and wind energy, making it more convenient for humans. This is the system that makes use of.

The solar power generation system not only generates electricity on days and nights when the sun is not shining due to rain, snow, or clouds, but also generates uneven direct current according to the intensity of the solar radiation. It has the disadvantage of increasing the capacity of the solar cell and increasing the capacity of the battery for storing power. Wind power does not generate electric energy because there is little wind on a sunny day, but on the contrary, at night or during rainy days or on a cloudy day There is a certain amount of wind can generate electrical energy can compensate for the disadvantages of solar cells.

In particular, the basic factors of algae growth in lakes and reservoirs include moderate nutrients, light, water temperature, and residence time, and proliferation of algae from the water surface to the water temperature layer during summer stagnation with abundant sunlight and high temperature Appears. Nutrients entering lakes and reservoirs are ingested by algae in the surface and promote their growth. In particular, during the summer, when stratification begins, nutrients (nitrogen, phosphorus, etc.) rise from the bottom of the lake due to sufficient sunlight, up-and-down circulation in spring, and reversal phenomenon, and nitrogen, phosphorus, etc. are introduced into the lake. Hydration or freshwater tide can occur. Algae, which are usually grown during summer stagnation, are propagated due to the introduction of nutrients, but some of them are settled at the bottom of the lake after their death and are deposited as organic matter. The deposited organic matter is initially degraded by bacteria under aerobic conditions, and the decomposition process consumes dissolved oxygen at the bottom of the lake, resulting in a lack of oxygen in the lake. Therefore, when oxygen is depleted at the bottom of the lake and changed to anoxic state, iron or manganese is reduced and eluted from the deposited layer, which may cause colored obstacles such as red water and black water.

The weather conditions in Korea during the summer season (July, August, September), where the algae is active, account for one-fourth of the month. Therefore, some power supply is limited only by solar light, and it is not possible to maintain a smooth underwater DO concentration in the algae maximum growth.

Therefore, a separate power supply is required on days when sunlight is not emitted by rain, snow or clouds.

In addition, a lot of pollution progresses in the lake or reservoir with high nutrient concentrations in the water to remove the nutrients in order to achieve effective algae removal. Therefore, if the impeller is installed inside the upper inlet pipe of the water column to rotate and mix with the flocculant including chemicals in the contaminated lake or reservoir water, the water in the bottom of the lake will be scattered to the upper part of the water column. Climb up to the surface of the lake to form a hydraulic vortex. Ocher, natural coagulants or chemicals were administered to the area where the hydraulic vortex was formed, and the injected chemicals were instantaneously mixed by the hydraulic vortex to diffuse into the lake. Infusion of flocculents such as natural flocculants should be used temporarily in case of severe contamination.

In addition, the rate of oxygen dissolved transport in water is governed by several factors.

    dC / dt = (Cs-C) ka

Where dC / dt is the instantaneous rate of change of the gas concentration in the liquid, Cs and C are the saturation and actual concentrations respectively, and ka is the constant associated with the given physical condition. The magnitude of the ka value is known to depend on the temperature of the system and the interface area of gas transfer and the resistance to transition from one phase to another. The larger the interfacial area per given volume, the greater the chance of gas delivery. Therefore, in order to increase the dissolution rate, the water in the lower layer introduced into the upper portion by the impeller was spread out thinly to the water surface to maximize the interfacial area.

The present invention has been made to solve the problems of the prior art as described above, for example, stagnation to prevent the abnormal growth of algae caused by nutrients in the stagnant water, such as lakes or reservoirs to prevent eutrophication proceeds.
