Description

Water Production System Using Rainwater and Sewage [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for reusing rainwater and sewage, and more particularly, to a system for reusing rainwater and sewage for collecting abandoned rainwater and sewage and reusing the collected rainwater and sewage as reusable water such as domestic water or industrial water. .

As is well known, reusable water from waste water means domestic water or industrial water obtained by treating sewage, and reusable water production system means sewage treatment system for obtaining domestic water or industrial water from sewage do.

In the past, it was common to discharge sewage water discharged from a sewage treatment plant to a river. However, as the need to reduce the burden on water resources development has emerged, the importance of reusing sewage treatment water is increasing. Accordingly, reuse of sewage water is obligatory, and water quality standards for reclaimed water are being prepared.

The reclaimed water production system can be constructed based on various water treatment processes capable of appropriately removing the pollutants contained in the sewage treatment water so that the reclaimed water can have a water quality suitable for its use purpose. For example, from a simple system suitable for production of low-quality reusing water consisting of a solid-liquid separation process and a disinfection process to a complicated system suitable for producing high-quality reusing water combined with physical, chemical and biological treatment processes, System has been proposed.

In addition, recent rainfall patterns have been concentrated in specific periods due to climate change. Therefore, measures to prevent flooding damage are urgently needed. As the amount of water available due to frequent droughts and water pollution is decreasing, It is expected that the problem will be further intensified, but the technology to cope with this situation is insignificant.

In order to solve such a problem, Japanese Patent Application No. 10-0842880 entitled " Filter Cartridge and Initial Pore Treatment Device for Initial Pore Treatment ", Patent Publication No. 2009-0033680 "Pore Treatment System and Pore Treatment Method & 1176360 "eco-friendly water reuse treatment system" has been disclosed.

Conventional stormwater treatment and water reuse apparatuses have a structure in which flocculants are injected into raw water to precipitate and separate sludge, and untreated oil in the pretreated treated water is discharged in the form of scum. There is also a method in which a separate ceramic carrier layer is provided and a backwash function is added. Such conventional technology has a problem in that it is inevitable to input power for injecting a drug, the process is complicated, and can act as a secondary pollutant source of effluent water due to chemical injection.

Another prior art is a technique for removing residual contaminants by biological treatment with microorganisms. However, this method requires a long period of time in order to exhibit the expected effect of pollutant treatment in a place where the load variation rapidly changes and the range of the non-point pollutant source and emission characteristic is wide and temporally centralized as in Korea. There are considerable problems.

FIG. 5 is a flowchart showing production of reusing water in the system for producing reusing water using rainwater and sewage according to the present invention.

As shown in FIG. 5, the initial rainwater and sewage are stored in the rainwater storage tank 100 and the sewage storage tank 200.

Thereafter, the stored rainwater and sewage can be measured by the rainwater level sensor 110 and the sewage level sensor 210. When the water level reaches a predetermined level, the controller 300 discharges rainwater and sewage And supplied to the reaction tank 400.

That is, the control unit 300 opens the rainwater discharge valve 130 connected to the rainwater discharge port 120 and the discharge outlet 220 and the rainwater solenoid valve 131 and the sewage solenoid valve 231 formed in the discharge water discharge pipe 230, And sewage.

Thereafter, in the reaction tank 400, rain water and sewage water are mixed, and the water is stirred to produce reused water by reaction with ozone.

More specifically, in the reaction tank 400, water is agitated by the agitator 410. This is because the rotation of the agitator shaft 411 and the agitation of the agitator shaft 411 are performed by driving the agitator motor 413, (412 ') and the mesh net 414 formed in the agitation blade 412'.

For example, when the chromaticity of the target drum 431 is measured in a relatively muddy state, a state in which the reused water can not be used yet, that is, an integer that is suitable for the reused water is not obtained, and the chromaticity of the target drum 431 is clear In the measurement, the water is purified to a state suitable for the use of the reused water. Such chromaticity can be determined by the perspective of the sensing part 433a according to the turbidity of water.

The reference chromaticity of the target drum 431 corresponding to the turbidity suitable for the use of the reusing water in the process of measuring the turbidity of water as described above is set to the chromaticity input unit 441 of the chromaticity meter 433 .

When the chromaticity of the target drum 431 is measured in the process of measuring the chromaticity of the target drum 431, the control unit 443 senses the chromaticity of the target drum 431 and the target drum 431 containing water through the observation camera 442, And then the photographed image is transmitted to the central control room 500 through the control unit 443 so that the operator can confirm the image.

That is, the photographing and transferring process as described above enables the operator to confirm the production status of the reused water in the central control room 500 even when the operator is not in the field.
