Description

Ubiquitous-Based Wastewater Reclamation and Reusing System}

The present invention relates to a ubiquitous technology for managing water produced in a water supply system, and more particularly, a real-time measuring instrument is provided to obtain water quality and quantity information to selectively or simultaneously withdraw multiple alternative water resources. The water treatment process is to be selectively adjusted according to the water quality and quantity information.

In general, heavy water refers to a facility for reprocessing tap water or rainwater once used so as to be recycled into living water, industrial water, and the like.

Recently, due to the water famine and global warming, the world has been experiencing difficulties in water use. Water is an essential resource for humans to maintain their lives and is currently available due to water shortage and pollution around the world. Securing water resources is very difficult.

In particular, in Korea, 70% of annual rainfall is concentrated in summer and seasonal. Due to regional bias and high stream coefficients in most rivers, the flow is lost to the sea at once, which can lead to severe water shortages if prolonged droughts are difficult.

In recent years, efficient water management and securing and utilizing alternative water resources are required in preparation for water shortages.As an alternative to this, alternative water resources such as advanced sewage treatment, rainwater, groundwater, riverside filtration, ecological rivers, and lake water are effectively used. Purification and reuse methods are being examined in various ways.

Among them, the typical method is to treat existing sewage treatment water by filtration process or biological treatment process by active microorganisms and use it as a heavy water, to collect rainwater effectively and reuse it, and to treat riverside filtration water as alternative water resources. Many technologies, such as how to use them, have been devised and applied, but most of these technologies are methods that can be used as a water source for a single source, and there are problems in terms of technology or efficiency in applying various sources to water. In addition, there is a limit to use as a uniform heavy water without reference to the treated water quality and quantity.

In addition, it is maintaining a limited use of recycled water, which is produced in a certain quantity and quality, without difficulty, and is used for a limited purpose without the supply and demand of water quality and quantity information for the reused water to be utilized in various ways.

Therefore, for the purpose of utilizing various alternative water resources as heavy water, we need a technology that combines the ubiquitous field to collect raw water selectively or at the same time and to select and send the water treatment method in real time according to the purpose of demand. Done.

The present invention has been proposed to improve the above problems in the utilization of the conventional water, the water quality and quantity of the inflow source water for a single source and the water quality and quantity information according to the purpose of use required by the water choir The purpose of this system is to provide a ubiquitous-based water-based system that can selectively apply unit processes so that rational use of recycled water can be achieved.

The present invention for achieving the above object, the multi-water source unit for supplying multiple water sources, such as sewage altitude treatment water and rainwater, groundwater, riverside filtration water, ecological river water; An influent monitoring unit configured to measure water quality and flow rate of the influent supplied from the multiple water source unit; A water treatment unit for performing physical and chemical filtering of water supplied through the inflow water monitoring unit; A discharge water monitoring unit configured to measure water quality and flow rate of the discharged water after the treatment in the water treatment unit; A water distribution unit for distributing the water monitored by the discharge water monitoring unit to a demand destination such as cleaning water, landscaping water, toilet water, fire fighting water, heat island prevention water, and ecological river maintenance water; The multi-water source unit, the influent water monitoring unit, the water treatment unit, the discharge water monitoring unit, the water supply control unit for controlling the water distribution unit; characterized in that it comprises a configuration comprising a.

The water-based water system of the present invention can be selectively supplied and distributed by allowing different water treatments to be made depending on the purpose of use required by the demand source for various raw water treatment targets.

In particular, if the water quality of the standard suitable for the purpose of use is satisfied in the process of 6 to 7 steps, it is possible to reduce the unnecessary water treatment costs by selectively discharged directly to the demand.

Therefore, it is possible to secure a stable amount of water, and by supplying the reused water to the demand source continuously, it is possible to reduce the dependence rate of water supply and to reduce the amount of sewage generated.

The effect of the operation of the ubiquitous based water-based system of the present invention constituting such a structure will be described.

In Korea, the water quality standards for use in relation to heavy water use are prescribed in the recommended water quality standards for reuse by sewage treatment water as shown in Table 1 below.

division Toilet water Watering Landscaping Car wash, cleaning water Total coliform count Not detected / 100mL Residual Chlorine (Coupling) 0.2mg / L or more 0.2mg / L or more - 0.2mg / L or more Exterior The user should not feel uncomfortable Turbidity (SS) Less than 2 NTU BOD Less than 10mg / L smell No unpleasant smell pH 5.8 to 8.5 Chromaticity Less than 20 degrees Less than 20 degrees COD Less than 20mg / L

Under these standards, the main applications are classified as flush toilet water, sprinkling water, landscaping water, car wash and cleaning water, etc., and the coliform count, residual chlorine, appearance, turbidity, biochemical oxygen demand, odor, pH, color, It can be confirmed that a suitable water quality standard for chemical oxygen demand is presented.

Therefore, in the ubiquitous based water-based water system of the present invention, the reused water is produced and supplied according to the usage by applying the standards thereof.

At this time, the rainwater or groundwater has better water quality than the sewage advanced treatment water, riverside filtration water and ecological river water, so that it can be utilized as good reuse water without going through many water treatment unit processes.

In addition, the high degree of sewage treatment water, riverside filtration water, and rainwater generated during the initial rainfall are treated according to the existing treatment methods and various conditions, and the water quality can be changed by discharge. To produce, the quality and quantity of water must be monitored in real time.

That is, the reused water supplied from the multiple water source unit 10 is measured in the inflow water quality and quantity in the influent monitoring unit 40, the influent is measured in the process via the water treatment unit 50 of the present invention The purification process is performed, in this case, the demand source 20 of the water is input to the controller 30.

Therefore, the control unit 30 checks the water quality measured by each discharge water monitoring unit 60 in the process of purifying the water treatment unit 50 step by step to a step suitable for the water quality standards for the purpose of utilizing the water. If confirmed, do not proceed any further purification step will be immediately discharged to the water distribution unit 70 will be supplied to the demand.

In particular, the present embodiment is composed of six unit process steps as an example of the water treatment unit 50, and the configuration for producing five types of reuse water through each unit process is shown, but finally depending on the purpose to utilize It can be seen that only three, four or five unit process steps can be used to produce recycled water that can be used for the demand.
