The present invention relates to a filtration treatment device using river water, reservoir, or sewage treatment plant effluent. More specifically, it includes an inflow pipe, a produced water supply pipe, and a filtration unit installed horizontally and a micro mesh that filters fine suspended substances in the inflow water. , It generates active free radicals with a charged microbubble oxygen generator and simultaneously generates active free radicals in the order of ozonation, hydrogen peroxide, and hydroxyl radicalization of oxygen molecules using complex ultraviolet wavelengths, thereby improving energy saving efficiency by reducing gravity during water treatment. It relates to a filtration treatment device that efficiently treats river water, reservoirs, or sewage treatment plant effluent by preventing the formation of biofilm on the surface of the filtration filter membrane.

Abnormal climate phenomena that are rapidly changing, especially extreme heat, sea waves, droughts, floods, typhoons, etc., and aquatic life such as algae, including harmful blue-green algae, occurring in polluted rivers, etc. are causing large changes in precipitation and serious river pollution. It is becoming. Moreover, while water use is increasing, green space is decreasing due to highways and urbanization, and the area of impervious layers is increasing, the amount of water in groundwater and reservoirs is significantly decreasing, and the level of pollution is also increasing, making it difficult to secure usable water resources such as drinking water and agricultural water. It has been done.

Accordingly, under the current law, the Ministry of Environment and the Ministry of Agriculture, Forestry and Fisheries have judged that it is appropriate to use domestic sewage or sewage as reused water for agricultural purposes in accordance with water quality standards, and the government has also reduced the proportion of reused water in municipal sewage treatment plants from 5-10% to 20%. It is mandatory to increase by %. Accordingly, in order to secure water resources for various uses, it has been proposed to use domestic sewage or sewage as reused water, but users are highly reluctant to do so.

Meanwhile, in order to overcome the shortage of reused water for use in agriculture, a method of reprocessing and supplying river water, reservoirs, and sewage treatment plant effluent is disclosed in patent documents 0001 and 0002. The above conventional devices and methods require the installation of expensive devices for water purification, which increases treatment costs. In terms of water quality, other harmful microorganisms, including Escherichia coli, are not completely removed and cause hazardous conditions in rivers and rivers. There are many problems with water treatment efficiency, such as the residual presence of various organic and inorganic substances.

In particular, the filtration method, which is one of the existing water treatment methods, has the problem of high maintenance costs because filter replacement is essential to continuously improve water quality due to clogging caused by microbial growth that occurs during operation.

Patent Document 0001, Patent Document 0002, Patent Document 0003, and Patent Document 0004 present agricultural water supply device technology that reuses effluent water from rivers and sewage treatment plants. The above patent uses colloidal nano water to increase the amount of dissolved oxygen in the treated water, and uses nano water to clean the auto screen filter unit. This patent can be used effectively and economically as it can be used continuously without replacing the filtration membrane. An agricultural water supply device and method are being disclosed.

However, in the above technology, the auto screen filter part is a vertical type and is perpendicular to the input pipe and discharge pipe, so the pressure loss is very large, and the microbubble generator does not fully exert the pollution prevention effect of the filter medium depending on the wide range of the contamination target. There is a problem. In this way, conventionally, the filtration device for the production of reused water from river water, reservoirs, and sewage treatment plant effluent is manufactured vertically, so as the water level increases, the pressure loss increases, increasing the energy required for the pump, and depending on use. The filtration part of the filtration unit used to treat effluent water generates biofilm depending on the period of disuse and the environment, causing problems in water filtration.

Accordingly, the present inventors have made diligent efforts to solve the above problems, and as a result, when the inlet pipe, the produced water supply pipe, and the filtration unit of the water treatment device are installed horizontally and a physical and chemical device is provided to kill microorganisms generated in the filtration membrane wash water tank, Compared to the existing vertical type filtration device, the pressure loss is lower and the efficiency of the device is improved through the energy saving effect of the pump. At the same time, the formation of biofilm that occurs on the filtration filter of the device during the operation stop period is suppressed through physical and chemical methods, thereby increasing the filtration membrane wash water. It was confirmed that cleaning efficiency could be improved and maintenance costs could be reduced by reducing the replacement of filters in the filtration unit due to improved prevention of contamination of the filter medium, and the present invention was completed.

The present invention includes a filtration filter included in the pipe-integrated horizontal filtration unit in which the inflow piping line and the produced water supply piping line are installed horizontally, and remove organisms and other suspended substances present in the influent water flowing through the inlet piping. Inside the filtration filter of the piping-integrated horizontal filtration unit, a charged ultra-fine bubble generator is installed to consistently generate ultra-fine bubbles for the purpose of producing active free radicals (hydroxyl radicals), and then the active free radicals (hydroxyl radicals) resulting from the collapse of ultra-fine bubbles are installed.

To prevent this, it includes a physical and chemical device that kills microorganisms occurring in the filtration membrane wash water tank.

Here, the following ozone generation reaction and radical generation reaction technologies are applied to increase the efficiency of reducing biofilm on the filtration membrane that is not completely treated by the UV disinfection unit.

[Ozone creation reaction]

H ₂ O + hv(185nm) → OH + H

O ₂ + hv(185nm) → O(1D) + O(3P)

O(1D) + O ₂ → O(3P) + O ₂

O(3P) + O ₂ + O ₂ → O ₃ + O ₂

[Radical production reaction]

O ₃ + H ₂ O + hν254nm → H ₂ O ₂ + O ₂

H ₂ O ₂ + 2O ₃ → 2 OH + 3O ₂

H ₂ O ₂ + hν254nm → 2 OH

O ₃ + hv(254nm) → O(1D) + O ₂

O(1D) + H ₂ O → 2 OH

When the amount of dissolved oxygen in the treated water increases using nano water, O ₃ is generated by Vacuum UV 200-100 nm and the oxygen is activated by _UV -C 280-200 nm. Using the principle, UV rays of Vacuum UV 200-100 nm are used to By generating ozone with the oxygen in the ozone, ultraviolet rays of 254 nm are emitted into the generated ozone to sterilize living organisms in the water through the generation of hydroxyl radicals, suppressing the formation of biofilms, and increasing the friction of treated water with the generated radicals to increase the efficiency of sterilization. In order to increase water circulation, there is also a need to improve water circulation.

Overall, the pressure loss is lower than the existing vertical type filtration device, which has the effect of reducing the energy of the pump. It also produces active substances by applying ultraviolet rays to sterilize by directly irradiating the filtration membrane washing water tank and using carbon dioxide or oxygen contained in the treated water. This reduces the number of organisms that may occur in the water treatment filtration membrane and improves the cleaning efficiency of the filtration membrane wash water by suppressing biofilm formation. In addition, the replacement of the filtration filter in the filtration unit is reduced by improving the prevention of contamination of the filter medium, thereby reducing maintenance costs.

In the present invention, a piping-integrated horizontal filter containing a micro mesh that filters fine suspended substances in the influent flowing in through the inlet pipe is required, and is mounted within the piping-integrated horizontal filtration unit to filter washing water into the piping-integrated horizontal filtration unit. After passing through the supply pipe, a charged ultra-fine bubble generator is installed inside to produce active free radicals (hydroxyl radicals) used for sterilization, and disinfection, oxygen generation, ozone generation and subsequent activation according to ultraviolet wavelengths. An ultraviolet sterilization unit that generates free radicals is installed, and a treated water circulation system is required at the bottom of the sterilization/disinfection unit to improve contact between the treated water and the activator.

In particular, the device of the present invention reduces the production of biofilm by including a micro mesh that filters fine suspended substances in inflow water generated when removing suspended substances and organic matter contained in water and treating it as reused water for the purpose of supplying agricultural water. In addition, the pressure loss is lower than that of the existing vertical filtration device, which has the effect of reducing the energy of the pump. In case of operation interruption, the cleaning efficiency can rapidly decrease due to the generation of biofilm on the filtration membrane, so the use of an charged ultra-fine bubble generator (activated free radicals) It supplies oxygen and removes suspended solids and microorganisms by generating hydroxyl radicals.

At the same time, along with the oxygen existing in existing water, ozone is generated with a wavelength of Vacuum UV of 200-100 nm, and then active free radicals (hydroxyl radicalization) are generated from the ozone generated with a UV-C wavelength of 280-200 nm, inhibiting the growth of organisms. The efficiency of water treatment filtration membranes is improved by suppressing the formation of biofilms on the top of the filtration membrane using modules and devices that induce sterilization by inducing genetic disruption of organisms and killing them, and also prevent contamination of the filter media, making it easier to replace the filter media. Since it is not necessary, maintenance costs for the reaction device that supplies reused water from river water, reservoirs, or sewage treatment plant effluent can be reduced.
