Abstract

The present invention relates to a water quality improvement system using microbubbles. A water quality improvement system using microbubbles according to the present invention comprises: an oxygen generator that separates and supplies high-purity oxygen to external air by a pressure-circulating adsorption method; a treated water pump that transmits treated water; a treated water storage tank that stores treated water into which oxygen microbubbles have been introduced; a photocatalytic device installed inside the treated water storage tank that can purify the treated water into which oxygen microbubbles have been introduced; and a microbubble generator that generates microbubbles from the oxygen supplied from the oxygen generator and introduces/absorbs them into the treated water flowing in through the treated water pump. According to the present invention, by allowing high-purity oxygen to be introduced/absorbed into the treated water in the form of microbubbles, the amount of dissolved oxygen in the treated water can be improved, thereby improving the water quality of the treated water.

Description

Water quality improvement system using microbubbles The present invention relates to a water quality improvement system using microbubbles, and more specifically, to a water quality improvement system using microbubbles that can improve the dissolved oxygen content of treated water by introducing/absorbing high-purity oxygen in the form of microbubbles into the treated water while transferring the treated water to a treated water storage tank using a treated water pump. In addition, the present invention relates to microbubbles General aeration tanks that supply air into water to improve the water quality of various types of water and sewage systems, as well as the water quality of reservoirs, dams, lakes, streams, and rivers, and aquaculture farms—that is, to improve DO (an indicator of the amount of dissolved oxygen in water)—have been used for a long time. However, these tanks have disadvantages such as requiring large devices and complex air supply lines, and complex structures, and they are not economical in terms of maintenance due to poor durability. Consequently, microbubble generators have recently been developed and are being used for water quality improvement. Although such microbubbles offer the advantage of high dissolution rates in water and good efficiency for water quality improvement, existing devices have numerous problems and disadvantages, such as complex structures and low efficiency. FIG. 1 is a drawing for explaining a water quality improvement system using microbubbles according to an embodiment of the present invention. FIG. 2 is a drawing for explaining a photocatalytic device according to an embodiment of the present invention. The object of the present invention is to provide a water quality improvement system using microbubbles capable of improving the dissolved oxygen content of treated water by generating high-purity oxygen as microbubbles and introducing/absorbing it into the treated water, and specific advantages and novel features will become more apparent from the following detailed description and preferred embodiments associated with the accompanying drawings. In addition, it should be noted that in assigning reference numbers to the components of each drawing in this specification, identical components are given the same number as much as possible, even if they are shown in different drawings. Furthermore, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. Also, in describing the present invention, detailed descriptions of related known technologies that could unnecessarily obscure the essence of the invention are omitted. A preferred embodiment of the title according to the present invention will be described below with reference to the drawings. As illustrated in FIGS. 1 and 2, an embodiment of a water quality improvement system using microbubbles according to the present invention is illustrated. Specifically, FIG. 1 is a drawing for explaining a water quality improvement system using microbubbles according to an embodiment of the present invention, and FIG. 2 is a drawing for explaining a photocatalytic device according to an embodiment of the present invention. As illustrated in these drawings, the water quality improvement system using microbubbles according to the present invention comprises an oxygen generator (100), a pressure regulator (200), a treated water pump (300), a microbubble generator (400), a treated water storage tank (500), and a photocatalytic device (600). First, it is preferable that the oxygen generator (100), pressure regulator (200), treated water pump (300), microbubble generator (400), and treated water storage tank (500) be connected by pipes. The oxygen generator (100) separates and supplies high-purity oxygen from external air supplied through a compressor, etc. Such an oxygen generator (100) can separate and produce oxygen with a purity of, for example, about 95%, while performing pressure swing adsorption (PSA) on air. Meanwhile, the oxygen generator (100) can separate and generate high-purity oxygen from the air and store it in an oxygen storage tank (not shown). The pressure regulating device (200) can regulate the pressure and supply high-purity oxygen generated from the oxygen generator (100), and can also regulate the pressure and supply high-purity oxygen stored in an oxygen storage tank (not shown). The treated water pump (300) pressurizes the treated water flowing in through the pipe to increase the flow rate and transmit it. The microbubble generator (400) generates microbubbles for the treatment water introduced through the treatment water pump (300) and for the high-purity oxygen introduced through the oxygen generator (100) or pressure regulator (200), and then introduces/absorbs them. The treated water storage tank (500) stores treated water in which high-purity oxygen is introduced/absorbed by the microbubble generator (400). The photocatalytic devic
