Description

Water treatment system using UV}

The present invention relates to a water treatment system using UV for recycling groundwater in order to secure water resources, and more specifically, rainwater flowing down from a roof, rooftop or road containing a large amount of contaminants and contaminants in the early stage of initial rainfall. In a water treatment device that pumps rainwater or groundwater stored in a confined space and discharges it after filtering and purification treatment, the pollutants remaining in the treated water are recycled and purified, so that rainwater or groundwater can be recycled or used for drinking. It relates to a water treatment system.

Non-point pollutants are pollutants that flow out with rainwater from non-point sources during rainfall. Soil, suspended matter, nutrients (nitrogen and phosphorus), heavy metals, organic substances, pesticides, garbage, residues, Bacteria in animal excrement and sewage overflow.

These non-point pollutants accumulate on the surface at high concentrations and are introduced into groundwater, valley water, rainwater, sewage treatment plants or rivers along with rainwater from unspecified places during rainfall, thereby deteriorating water quality.

Therefore, it is inappropriate to use stored rainwater or groundwater containing nonpoint pollutants for the purpose of drinking.

Efforts are being made to reduce water pollution in public waters by non-point pollution sources due to rapid industrialization and uncertainty of rainfall.

In general, the traditional method of purifying rainwater that flows along roads and flows into rivers or groundwater in rainy weather is to create a puddle near the road so that rainwater can be collected, and to grow plants with water purification ability, such as water parsley, It was to allow the rainwater to be purified and then discharged.

However, as the population gradually became denser and the size of the city increased, the inflow of non-point pollutants increased, requiring a separate filtering facility. In particular, in camps of military bases where the supply of water supply and living water is impossible, a plan to purify and use groundwater is being sought.

These filtration plants are water treatment units with settling, aeration and filtration.

In addition, even in public baths such as swimming pools and public baths, a highly efficient water treatment device is required to maintain clean water quality, and in the era of coronavirus infection-19 (COVID-19), strong cleaning capacity in multi-use facilities such as the above It is essential to carry out routine disinfection through water treatment with

An example of a rainwater treatment device capable of separating, filtering, and discharging various contaminants contained in rainwater of the initial rainfall has been proposed in Korean Patent No. 10-0897258 “Non-point pollutant treatment device included in rainwater”.

In the use of rainwater, in general, rainwater in the early stages of rainfall is accompanied by contaminants distributed in the air, as well as various contaminants such as paper, leaves, wood chips, and synthetic resins scattered on the roofs of buildings or houses and on the ground. Pollution of water systems such as rivers, streams, and lakes is caused. It consists of a rectification tank that temporarily stores and discharges the rainwater treated in the sedimentation filtration tank.

This device has a structure in which contaminants are primarily separated in a screen installed right below the outlet side of the supply pipe into which non-point pollution sources are introduced from the outside, and then rainwater that has passed through the screen is stored in a settling tank, so that there are many non-point pollution sources that are initially introduced. In this case, rainwater can be used for the purpose of gray water and cannot be used as drinking water because there is a structural problem in that the treatment process is not smooth, such as that the upper space of the screen is blocked and non-point pollution sources overflow.

And in the rainwater treatment device in which the flow of rainwater moves upward in the sedimentation filter tank, contaminants attached to the filter gradually accumulate, resulting in a problem that the filtration and discharge functions cannot be performed smoothly. Most rainwater treatment devices As it is buried underground, it becomes impossible to artificially remove contaminants attached to the filter. Accordingly, a device for backwashing the filter has been devised. Conventional backwashing devices use a separate water supply, which wastes water resources and increases the cost of waterworks. there will be no

In addition, in the rainwater treatment device, all of the rainwater treated structurally is not discharged and is trapped in the grit tank, the filtration tank, and the rectification tank. This rainwater is easily decayed by organic pollutants to generate odors or to breed and breed pests such as mosquitoes. It can be a factor that harms the environment by providing an optimal environment for

In the following, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart showing the water purification process of the present invention.

Referring to FIG. 1, the water purification method of the present invention pumps water to be treated, such as rainwater or groundwater, stored using a pump 10, and stores the pumped water to be treated in a storage tank 20 ( S100) and; Filtering the water to be treated stored in the storage tank 20 in the filter unit 300 (S200); forming microbubbles in the filtered water to be treated by operating the nanobubble generator 310 (S300); sterilizing microorganisms by operating the UV sterilizer 320 (S400); detecting a water purification state by detecting the sterilized treatment target water in the sensing unit 330 (S500); transmitting the purified state data sensed by the sensor 330 to the controller 50 to determine the purified state (S600); The control unit 50 displays the result of determining the purification state of the treated water (S700) and stores the purified treated water in the treated water storage tank 40 (S800).

The present invention can be operated by selecting an automatic mode and a manual mode in the control unit 50.

Commonly in the automatic mode and the manual mode, the control unit 50 displays the result of determining the purified water status (S700), and transmits the result of determining the purified water status to the management server 60 and the user terminal 70 (S710). ).

In the automatic mode, if the turbidity is higher than the normal value according to the result of determining the water purification state, the treated water discharged from the sensing unit 330 is fed back to the filter unit 300 to perform re-water treatment.

In addition, if the turbidity and the biological oxygen demand are below the normal value according to the result of determining the purified water, the treated water discharged from the sensing unit 330 is fed back to the nano bubble generator 310 to perform re-water treatment.

In addition, according to the result of determining the purification state of the treated water, if the degree of bacterial contamination is higher than the normal value, the treated water discharged from the sensor 330 is fed back to the UV sterilizer 320 to perform re-water treatment.

In the manual mode, the water purifying device 30 is selectively operated from the management server 60 and the user terminal 70 according to the result of determining the water purification state, that is, the filter unit 300, the nano bubble generator 310, and the UV sterilizer. While selectively operating the 320, the water to be treated is recycled and treated as purified water.

2 shows a schematic diagram of a water purification system using UV according to the present invention.

Referring to FIG. 2, the water purification system using UV according to the present invention includes a pump 10, a storage tank 20 for storing the water to be treated, a filter unit 300, a nano bubble generator 310, and a UV sterilizer 320. ), a sensing unit 330, and a control unit 50, and may further include a management server 60 and a user terminal 70 for remote control.

The pump 10 pumps groundwater with a submersible motor pump and supplies it to the storage tank 20 for storing the water to be treated. do.

The storage tank 20 for storing the water to be treated stores underground water or rainwater transported from the pump 10, and a circulation motor is provided on the outlet side to supply an appropriate amount to the filter unit 300.

The filter unit 300 is used to primarily remove various foreign substances mixed in the water to be treated transferred from the storage tank 20, and a multi-filter composed of a plurality of filter members is used.

The multi-filter is composed of a sediment filter 301, a pre-carbon filter 302, and a carbon fiber filter 303.

The precipitate filter 301 is a filter made of high-density polypropylene of 5 μm or less and performs a mechanical filtration action of filtering out contaminants of 5 μm or more and removes dust and other particles present in the water to be treated. In the case of stored rainwater and groundwater, it is possible that the water contains sand, iron particles and other soil components. These contaminants have relatively large particles and can cause abnormalities in the components of the water purifying device, as well as being unavailable for drinking. Therefore, a special precipitate filter must be used in the first stage of purification to filter out fine particles.

The precipitate filter 301 may vary in filtration range from coarse to fine. For example, a 5 micron filter can filter out particles that are 5 microns in size or larger. In general, tap water supplied from public water sources is usually filtered using 5, 10, and 20 micron sedimentation filters. Several coarse filters are made for the removal of large sand particles, which vary in size and design, but come in three types: fiber, bubble, and pleated film. Among them, the wrinkled film type has the largest surface area and can be used for a long time until dirty contaminants accumulate and become clogged. It has the advantage that bacterial growth is difficult due to flow action, so it is most suitable for the water purification system using UV of the present invention.

The pre-carbon filter 302 is processed by high heat treatment of coconut, and is mainly used as a secondary filter to remove odors by adsorbing and removing organic chemicals by using the adsorption properties of carbon. will give

The carbon fiber filter 303 is a fibrous activated carbon made by firing and carbonizing and activating natural fibers, artificial organic materials, and chemical fibers as raw materials. Micropores are formed on the surface of the fibers, so the surface area is very large at 1,100 to 1,600 m/g, and the pore diameter It is evenly 10~14Å and has a small pore structure. The carbon fiber filter 303 has a very fast adsorption rate, and has an excellent separation effect by adsorption of micropores, suppresses bacterial growth, and removes unpleasant odors and color components to make colorless and odorless clean water.

Preferably, a turbidity sensor 331 is installed between the precipitate filter 301 and the precarbon filter 302.

The turbidity sensor 331 sends an alarm to replace the precipitate filter 301 through the display unit 520 and the alarm unit 530 in the control unit 50 when there is a turbidity higher than a standard value in the water to be treated through the sediment filter 301. A lamp is displayed and transmitted to the management server 60 and the user terminal 70 .

The water to be treated that has passed through the filter unit 300 forms nano bubbles by the nano bubble generator 310 .

The nano bubble generator 310 generates a large amount of strong oxidizing free radicals in the water to be treated in a low-oxygen state, adsorbs polluted organic substances, eradicates harmful bacteria, and dramatically reduces pollutants such as sludge odor. In addition, it improves water quality by increasing dissolved oxygen (DO) and activating aerobic microorganisms, aerobicizing anaerobic sediments such as ammonia, hydrogen sulfide, and acetaldehyde to remove odors and improving water quality such as BOD, COD, and SS to use as drinking water It becomes possible to provide treated water suitable for the following.

Nano bubbles are collectively referred to as ultra-fine bubbles with a diameter of 10 nm to 50 nm. They are reduced to nano bubbles with a diameter of 10 nm or less by internal contraction, and then generate high-temperature high-pressure ultrasound and free radicals to crush and disappear. The bubble stabilizes and stays underwater for several months.

The surface of nanobubbles is charged with electricity, and micro-nano bubbles containing oxygen have an active effect on organisms, and in particular, micro-nano bubbles containing ozone have a strong sterilizing effect. In addition, ozone micro-nano bubbles generate OH radicals during oxidative decomposition of hard-to-decomposable materials in water treatment, and show the same effect as performing hydrogen peroxide and ultraviolet irradiation concurrently.

For the nano bubbles, various types of pumps may be used in addition to the nano bubble generator 310 described above. Examples include multistage pumps, centrifugal pumps, rotary pumps, and regenerative pumps.

The multi-stage pump has a driving pressure of 5 kgf / cm or less, and when compressed air is introduced into the treated water discharged from the filter unit 30 in a state of being joined, a plurality of impellers rotating by driving a motor are multi-staged. It is installed in layers and repeatedly performs the suction pressure transfer process to generate large-capacity nano bubbles in micro units.

A centrifugal pump is a pump that pumps water by applying pressure energy to water with centrifugal force caused by the rotation of an impeller.

A rotary pump is also referred to as a rotary pump, and is a pump that transports fluid by moving a closed space generated by the rotation of a rotor inscribed in a casing so that there is almost no gap. There are vane pumps equipped with electronic flat vanes, gear pumps equipped with gear wheels, and screw pumps equipped with screws.

The regenerative pump uses a method in which a lot of grooves are dug around the impeller and when it rotates, the liquid that enters the grooves from the inlet side is surrounded by a casing and transported out of the outlet. The regeneration pump uses the viscous force of the fluid to rotate a smooth rotating body or a rotary shaft with a screw in the casing, thereby giving pressure energy by the fluid frictional force of the liquid and sending it out. Compared to centrifugal pumps, high lift can be obtained, but the highest efficiency is lower.

The water to be treated that satisfies the biological and biochemical oxygen demand by the nano bubble generator 310 is transported to the UV sterilizer 320 and sterilized.

3 is a perspective view of a partially cut-away UV sterilizer 320 applied to the present invention, FIG. 4 is a front sectional view of the UV sterilizer 320 applied to the present invention, and FIG. 5 is a UV sterilizer applied to the present invention ( 320) are respectively shown.

3 to 5, the UV sterilizer 320 uses an electrodeless UVC lamp 321.

The electrodeless UVC lamp 321 is a lamp without electrodes by mounting a ferrite core outside the lamp instead of the internal electrodes of conventional lighting such as a filament and a light emitting tube. When high frequency is applied to the ferrite core by an inverter dedicated to electrodeless lamps, a magnetic field is generated according to the law of electromagnetic induction, and this magnetic field reacts with the encapsulated gas inside the lamp to emit ultraviolet rays. The lamp material is made of high-purity quartz tube and fluorescent material It is designed to emit UV rays as it is by omitting the coating.

The UV sterilizer 320 of the electrodeless UVC lamp 321 forms a magnetic field of 12,000 gauss so that water stains do not occur and microorganisms such as bacteria can be sterilized.

In the electrodeless UVC lamp 321, titanium dioxide (TiO) is coated as a photocatalyst on the surface of the reflector 322.

Titanium dioxide photocatalyst is an n-type semiconductor that is harmless to the human body due to its acid resistance and alkali resistance. Super oxide oxidizes and decomposes organic compounds to change them into water and carbon dioxide gas, and kills bacteria through strong oxidation.

The ultraviolet irradiation method uses a phenomenon in which ultraviolet rays having a wavelength of about 10 to 400 nm have a destructive effect on microorganisms, and an ultraviolet (ultraviolet rays, UV) lamp using a UVC 254 nm wavelength that does not generate ozone may be used.

The specifications of the non-electrode UVC lamp 321 are not limited, but it preferably uses a power of about 400 W, has a wide ultraviolet irradiation area and high sterilization efficiency to generate ozone of about 185 nm, and has high water treatment ability, and a waterproof member with sufficient waterproof power. is unnecessary, it is environment-friendly with energy saving and long parts replacement cycle, it is easy to operate, and it has a structure that enables remote inspection with a simple structure.

The sensing unit 330 includes a plurality of sensors, such as a turbidity sensor 331, a pH sensor 332, a bacteria meter 333, and a temperature sensor 334.

The turbidity sensor 331 detects foreign substances such as dust or dissolved solids (TDS) remaining in the water to be treated after being sterilized by the nano bubble generator 310 and the UV sterilizer 320, and removes contaminants in the automatic mode. If it is above the reference value, the control unit 50 automatically determines whether or not to selectively operate it.

The pH sensor 332 detects a pH suitable for control requirements of the hydrogen ion concentration (pH) of the water to be treated that is sterilized by the nano bubble generator 310 and the UV sterilizer 320 and discharged. For example, the criterion for pH that can cause dental caries (cavity) is 5.5, and when this is set as the standard, selective operation is automatically determined from the control unit 50 in the automatic mode.

The bacteria meter 333 can directly measure bacteria, microorganisms, fungi, etc. from the water to be treated by ATP enzyme measurement by luminescence analysis, and selective operation is automatically determined by the control unit 50 in automatic mode.

The temperature sensor 334 makes it possible to indicate the temperature of the treated water to be finally purified.
