Description

A water-purifying treatment device with renewable energy generation plant and using waste glass and artificial filter medium Manufactured by Method}

The present invention is to treat and remove various pollutants, such as organic substances, floating substances, nutrient salts, etc., contained in sewage treatment plants, wastewater treatment plants, factory wastewater treatment plants, and sewage and wastewater flowing into individual sewage purification facilities by biological treatment methods. The present invention relates to a sewage treatment system and a treatment method therefor.

Accordingly, the present invention is a bioreactor that removes nitrogen and phosphorus by establishing a 'Comprehensive Management System for Bioreactors utilizing ICT' equipped with PH, NH ₄ -N, MLSS, dissolved oxygen (DO) sensor and operation control device. The operating conditions of the reactor can be sensed in real time by season and time, and the pH and dissolved oxygen (DO) concentrations of the influent are monitored in real time, and the air supply volume of the expiratory tank and the internal circulation of nitric oxide can be automatically adjusted / managed. As such, it is characterized by reducing the installation cost of the facility, reducing the area of the required site, and promoting economic efficiency through the reduction of the blowing power cost of the bioreactor.

In addition, the present invention is equipped with a device capable of producing new and renewable energy such as solar and wind power at a spare site of a sewage treatment plant in order to prevent a reduction in nitrogen and phosphorus removal efficiency due to a drop in water temperature in the sewage during the winter season. It is characterized in that the stability of the treated water is maintained by improving the removal efficiency of nitrogen and phosphorus by supplying it as a power source to a heating device that increases the water temperature of the winter bioreactor.

In addition, the present invention is to establish a system to remotely monitor the operation status of the sewage treatment plant using the latest IT technologies such as smartphones, PCs, CCTVs, laptops, etc. In the event of an emergency, it is formed to enable quick initial action through alarm provision, SNS notification, etc., and features a system that can remotely and unattendedly monitor the operation and control of major devices to reduce the workforce. Is done.

In general, sewage, wastewater, and stormwater contain various pollutants such as organic matter, suspended matter, nitrogen, and phosphorus. When discharged without proper treatment, it causes water pollution and eutrophication of the discharged water, which adversely affects the aquatic ecosystem. I go crazy.

To solve this problem, these contaminants are usually treated in a public treatment facility by biological treatment by microorganisms.

On the other hand, when the nitrogen and phosphorus pollutants are treated with the above conventional biological treatment method, the energy required to supply the air necessary for the growth of microorganisms in the bioreactor takes up about 40% of the energy required for the entire treatment plant.

However, the existing bioreactor cannot do the real-time monitoring of the state in water during the process of nitrification and denitrification (there is insufficient system to automatically control the air supply and nitric oxide circulation). It is impossible to respond appropriately to the change, which inevitably leads to unstable treatment efficiency, and in the end, there is a risk of exceeding the effluent water quality standards. It is designed to be somewhat over-designed than required capacity.

In other words, among the energy costs for operating the sewage treatment plant, the blowing power ratio for supplying air to microorganisms in the bioreactor occupies about 40% or more of the total power cost, so the energy cost can be reduced by optimizing the air supply to the bioreactor. There is an increasing need for technology development, and in recent years, technology that enables automation of operation management and further stabilization of water quality is also required.

On the other hand, in order to solve the above-mentioned problems, an invention patent for denitrification and nitrification of a bioreactor (patent 10-0432518 / 2004.05.11. Registration-hereinafter referred to as 'prior patent') has been devised.

This previous patent relates to a wastewater treatment system and method for performing continuous denitrification and nitrification under a low dissolved oxygen (DO) concentration of 0.6 mg / L or less in a single reactor.

Accordingly, the main technical point of the previous patent is a sensor unit consisting of a dissolved oxygen (DO) sensor, a pH (pH) sensor, and an electron transport enzyme enzyme inside the single active reactor, and is installed on the bottom or side of the single active reactor. Oxygen depletion rate control valve, variable blower, and an oxygen supply unit consisting of a mix are installed, and the signal received from the sensor unit is electrically connected to the sensor unit, and the BPA change amount and the pH (pH) change amount are calculated using the built-in calculation program. The reaction step determination device is installed to determine whether the reaction step is finished by generating a determination signal, and a control unit is provided to be electrically connected to the reaction step determination device to control the operation of the oxygen supply unit and the mixer, and the processed water state. It is formed to judge whether denitrification and nitrification are finished from the values.

However, this previous patent is a technique for increasing the nitrification and denitrification effect by controlling the air supply and flow rate by the electron transfer coenzyme sensor (NADH sensor), but the monitoring and control device is somewhat complicated due to the attachment of the sensor. In the case of deterioration of the treatment conditions, such as the decrease in water temperature, the effectiveness of nitrification and denitrification has not been properly demonstrated, and it is difficult to confirm the effectiveness of the technology, efficiency, etc. by comparing with the existing anaerobic, anaerobic, and aerobic methods.

In other words, in consideration of the decrease in the removal efficiency of total nitrogen and total phosphorus due to the decrease in the water temperature of the influent flowing into the sewage treatment plant during the winter season (December 1 to March 31), the water quality standards of the discharged water for the pollutants are alleviated. Although it has been applied, the government has revised the relevant laws and regulations as of July 17, 2014. As the deletion is implemented, it is urgent to develop a technology for improving the treatment efficiency of the pollutants during the winter.

In addition, apart from the previous patents above, in the recent market, a remote monitoring and control system incorporating the latest IT technology and solar power, etc. are used in the free space of the sewage treatment plant to produce new and renewable energy. The development of new and advanced technology that can be used as a situation is urgently required.

At this time, a multi-functional eco-friendly sand filter material 353 equipped with a backwashing device 352 is stacked by the strainer support 354 inside the filter housing, and communicates with the filtered water supply pipe 351-1 at the upper end of the filter housing. The cross-shaped trap (357) in the form of a cross is formed.

At this time, the filtration device 350 is provided with a water level sensor 355 and a backwash water outlet 356 on one side and the other side of the filter housing, and the eco-friendly sand filter material 353 stacked on the strainer support 354 is thick. The gravel layer and the fine sand layer are made to have upper and lower layers.

In addition, a side discharge valve 356-1 is formed on one side of the filtered water in order to discharge the filtered water generated in the backwashing process to the backwashed water outlet 356, and the backwashed water generated on one side end of the overflow trap 357 It is preferable that the backwashing water upper discharge valve 357-1 is formed in order to discharge it to the discharge port 356.

On the other hand, the strainer support 354 is to be provided with a plate panel 354-2 having a plurality of coupling holes 354-1 formed thereon, wherein the coupling hole 354-1 has a strainer member 354-3 assembled It is formed as possible.

At this time, the strainer member 354-3 is formed with a hollow tube 354-31, which penetrates through the coupling hole 354-1 and branches outwards at both ends of the plate panel 354-2, and the hollow tube ( 354-31) is formed with a thread on the outer circumferential surface so that the upper grille cone 354-32 and the lower tightening nut 354-33 are combined.

Accordingly, an air discharge plate 354-35 having an exhaust groove 354-34 is formed between the grille cone 354-32 and the tightening nut 354-33 to form a strainer member when high pressure air is introduced during backwashing. It is formed so that the exhaust grooves 354-34 are always discharged without remaining in (354-3), and is formed to prevent the loss of the multifunctional eco-friendly sand filter material 353 by not causing air bubbles during backwashing. .

To explain this in more detail, in the past, excess air was lost due to air remaining under the strainer member after backwashing with air in order to remove the suspended matter trapped in the filter medium.

That is, in the process of discharging the backwashing water, a problem occurred in which residual air at the lower part was discharged to the upper part together with the filter medium, and the strainer member had a wide eye (W = 1.5mm) and the basic filter material was gravel (5-10mm) and royal sand ( 2.5 ~ 5mm), causing some fine filter media to be lost through the lower support layer.

This is because the multi-functional eco-friendly sand filter media has a fine particle size of 0.4 to 1.4 mm, so that they are partially lost through the royal sand, gravel layer, and strainer.

Therefore, the conventional strainer member backwashes the filter medium with air and then flows the backwash water from the bottom to the top to float the filter medium, and then, in the process of stabilizing the filter medium, the floating material flows into the bottom of the filter medium and then flows back to the bottom during filtration. As the suspended material flows out for a certain period of time (5 minutes), the phenomenon that water quality deteriorates occurs.

The present invention is to improve this, and in the backwashing process, an exhaust groove, which is a structure capable of discharging residual air remaining under the strainer, is formed to prevent loss of media due to residual air.

To this end, the strainer member of the present invention has a strainer member because the previously installed strainer member has a snow neck of 1.5 mm, so that the filter material is leaked to the lower part of the strainer member because the multi-functional eco-friendly sand filter material has a particle diameter of 0.4 to 1.4 mm. It is formed to prevent the filter medium from being lost to the lower part when backwashing by forming the above-described exhaust groove while replacing the eye neck with 0.5 to 0.8 mm.

As described above, the filtration device is a down-flow filtration device in which the filtered water transferred from the secondary sediment is sent downward from the top, and is configured to be filtered while penetrating through a multi-functional eco-friendly sand filter medium.

On the other hand, if the filter layer structure of the filtration device is described in more detail, it is composed of a strainer support having a plurality of strainer members combined, a gravel layer, a coarse sand layer, a fine sand layer, and a multifunctional eco-friendly sand filter material.

At this time, the strainer member is sufficiently installed at regular intervals to prevent the gravel, coarse sand, fine sand, and multi-functional eco-friendly sand filter material seated thereon from leaking under the filtration layer and sufficiently discharge the filtered water to the outside. It is desirable to do.

Further, as described above, the strainer member is installed not only for the purpose of preventing the loss of gravel, coarse sand and fine sand, multifunctional eco-friendly sand filter material, but also moves air and backwash water evenly upstream when backwashing the filter layer. It also plays a role in helping.

Thus, under the strainer support, a discharge valve for discharging filtered water to the outside is installed. The discharge valve (351-3) has a flow control function that can automatically adjust the amount of filtered discharge according to the level of the filtered water and provides air for backwashing. It is desirable to have an air diffuser that can eject evenly and a device that supplies backwash water.

Thus, the backwashing device 352 of the filtration device 350 is to be provided on the lower side of the filtration enclosure 351, so that the high pressure air is injected into the air diffuser 352-12 by the blower 352-11 A backwashing device 352-1 is formed, and the pump 352-21 and the backwashing tube 322-22 are supplied to the lower other side of the filter housing 351 through the inverter for disinfection and discharge to receive backwash. It is preferable that the backwashing apparatus 352-2 having a) is further provided.

In more detail, if the filtered water is no longer filtered by contaminants to be laminated on a multi-functional eco-friendly sand filter material, if the filtration speed is slowed or the discharge amount is significantly reduced, the level of raw water in the precision filter increases.

At this time, the filtering device is formed to measure changes in the level and flow rate of the filtered water in the filter housing by means of any one sensor such as a wire-type water level meter or an ultrasonic water level meter.

For example, when the filtered water rises above a predetermined level, more specifically, when the filtered water level fluctuates, the sensor detects it and, on the other hand, sends the treated water filtered through the filtration layer to the outside through the water discharge pipe 351-2. do.

At this time, when the flow rate of the filtered water is measured in real time or irregularly, when the flow rate of the filtered water to be discharged along the water discharge pipe does not reach a preset flow rate, the filtration process is stopped and the filtered water remaining in the filter housing is filtered. After discharging to the outside of the filter housing through the filtered water side discharge valve (356-1) and the backwash water outlet (356) installed on the side of the housing, the air and the reverse air flow upward from the bottom of the filter housing to the filter layer using a backwashing device. Supply wash water.

As an optional example, the backwashing facility is supplied with air first to completely separate the contaminants trapped in the multi-functional eco-friendly sand filter layer from the filter medium, and then supply backwashing water to provide the multi-functional eco-friendly sand filter material with the specific gravity difference between pollutants. A multi-functional, eco-friendly sand filter with a high specific gravity is first precipitated, and contaminants floating due to its light specific gravity are discharged to the outside of the filter.

In addition, the backwash water is injected in the opposite direction to the flow direction that is filtered by a pump having a structure capable of controlling the backwash supply flow rate by an inverter device, and the multifunctional eco-friendly sand filter material blocked by contaminants in the filter layer is topped. It is formed so as to prevent clogging of the filtration layer by separating the contaminants attached to the surface while dispersing with.

Contaminants exfoliated by the backwashing float on the filtration layer portion and are discharged to the effluent storage tank after passing through the backwashing water upper discharge valve (357-1) and the backwashing water outlet provided in the upper stream trap of the upper part of the filter housing. The discharge valve is installed at the end of the inlet trapping device so that the multi-functional eco-friendly sand filter material is not lost to the outside due to the vortex of the backwash discharge water.

At this time, if the air supplied during the backwashing process remains under the lower support of the filter housing, the residual air is discharged to the upper part of the filter layer during the discharge process of contaminants, and some of the multi-functional eco-friendly sand filter material is floated to the top and will be lost along with the discharged water. Therefore, the lower support strainer of the filter housing is provided with a groove-shaped cross-sectional structure capable of completely removing residual air to the top of the filtration layer during the backwashing water supply process.

At this time, it is preferable that the sewage advanced treatment apparatus further comprises a remote monitoring monitoring system 500 that enables real-time monitoring and control of the operation state through an IT device including a smartphone, a PC, a CCTV, and a laptop.

In addition, the remote monitoring and monitoring system 500 is configured to provide an alarm and provide SNS notification when an emergency occurs beyond the efficiency of the sewage treatment system due to a malfunction of the advanced sewage treatment system. It is formed to be remotely adjustable.

Thus, the advanced sewage treatment device is further equipped with a new and renewable energy device 600 so as to supply electric power produced by solar and wind power to the heating device 610, thereby preventing a decrease in the water temperature of the sewage flowing into the bioreactor to nitrogen. It is formed to prevent the reduction in removal efficiency.

First, as shown in Figure 1, the advanced sewage treatment system of the present invention, when the sewage flows into the sewage treatment plant through the sewage collection pipe, the screen tank, sedimentation basin, flow adjustment tank, primary sedimentation tank, anaerobic tank, anoxic, exhalation tank, secondary sedimentation tank, filtration It is composed of a water treatment system passing through a device, a disinfection and discharge tank, and a concentration tank, a sludge storage tank, and a dewatering process for treating sewage sludge generated in the water treatment process.

Thus, the primary sedimentation tank 100 removes fine organic particles with respect to the inflow sewage from which sediments and debris have been removed through a screen tank and a sedimentation site (not shown) of a sewage treatment plant, as shown in FIG. It is formed in a gravity sedimentation structure to reduce the filtration load of.

At this time, the screen tank of the sewage treatment plant is composed of a small screen that removes small contaminants and a small screen that removes large contaminants to remove large suspended solids and contaminants mixed into the sewage.

In addition, the sedimentation site of the sewage treatment plant is composed of a sedimentation facility that has heavy specific gravity such as sand in the sewage and sinks and removes inorganic particles.

Accordingly, the bioreactor 200 is largely composed of an anaerobic tank 210, an anaerobic tank 220, and an aerobic tank 230.

At this time, the anaerobic tank 210 is a schematic cross-sectional view of the anaerobic tank for phosphorus removal as shown in Figure 2 or 3, the effluent from the primary settling basin and the return sludge recovered from the secondary sedimentation tank to the activated sludge microorganisms It is formed to decompose in the anaerobic state and release phosphorus.

Thus, the anaerobic tank 210 includes a stirrer or a water stirrer 211 for rotating a shaft having a plurality of blades by a driving motor to prevent precipitation of the conveyed sludge introduced from the secondary sedimentation tank; A bypass channel 212 that allows the inflow water to flow directly into the interior without passing through the primary sedimentation tank when it is determined that there is insufficient organic matter therein; A sludge supply pipe 213 in which a series of supply lines are formed to receive the sludge from the primary sedimentation tank if necessary; It consists and is made.

In other words, in the anaerobic tank, when the effluent from the primary sediment and the sludge from the secondary sediment are introduced into the anaerobic tank through a transfer pump and piping, phosphate phosphorus is released into the body of the activated sludge microorganisms in an anaerobic state without air.

To this end, the residence time of the anaerobic tank is 1 hour to 2 hours, and a stirrer is provided to prevent precipitation of the return sludge, and since organic substances in the influent are used as hydrogen donors for phosphorus release and denitrification, the concentration of organic substances in the influent is low. If it is judged that this is insufficient, a bypass channel for directly introducing the influent into the anaerobic tank without going through the primary sedimentation tank, and piping for receiving the primary sedimentation sludge are provided.

In addition, the anoxic tank 220 is a schematic cross-sectional view of an anoxic tank for denitrifying nitrogen as shown in FIG. 2 or 4, and nitric acid nitrogen (NO ₃ -N) with respect to effluent from the anaerobic tank and nitric acid circulated in the aerobic tank It is formed to denitrify by reducing to nitrogen (N ₂ ).

Thus, the oxygen-free tank 220 is largely composed of an inlet 221, a stirring device or a water agitator 222, an aeration device 223, and a carbon supply device 224.

At this time, the inlet 221 is formed so that the nitric oxide is introduced from the end of the exhalation tank.

In addition, the stirring device or the water stirrer 222 is formed so that the shaft having a plurality of blades rotates by a driving motor to prevent precipitation caused by the precipitation of nitric acid liquid introduced from the exhalation tank.

At this time, the aeration device 223 is formed on one side of the stirring device to prevent precipitation of the nitric acid solution and consequent decay.

Accordingly, the carbon supply device 224 is formed to supply an external carbon source including methanol inside.

In other words, the anoxic tank performs a process of denitrifying microorganisms denitrifying with nitrogen gas using organic matter when nitric acid is introduced into the anoxic tank by means of an internal circulation facility at the effluent of the anaerobic tank and the end of the aerobic tank. The chemically bound oxygen is circulated internally from the aerobic tank to the nitric acid solution, which is formed to remove nitrogen through a denitrification reaction in which nitrogen gas (N ₂ ) is formed by the denitrifying microorganism.

The denitrification reaction in which nitrogen nitrate (NO ₃ ⁻ ) contained in the returned nitric acid solution is converted into nitrogen gas (N ₂ ) under oxygen-free conditions is as follows.

* Denitration ^{_{reaction: 2NO 3 - + 2 (H}} 2) 2NO 2 - + 2H 2 O

^{_{2NO 2 - + 3 (H 2}} ) N 2 + 2OH - + 2H 2 O

The residence time of the anaerobic tank is about 1 hour to 1.5 hours shorter than that of the existing anaerobic, anaerobic, and aerobic methods in view of the characteristics of the present invention, which complements the denitrification deficiency after performing nitrification and denitrification in the aerobic tank, and the inside of the nitric acid solution The circulation rate is also 40 ~ 100%, so the capacity of anoxic tank can be reduced to a maximum of 1/4 level compared to the existing method.

In addition, the aerobic tank is equipped with an aeration device or a stirring device to form aeration using air or agitation using an agitator to prevent decay due to precipitation of sludge in the anoxic tank and to supply external carbon sources such as methanol. The device is formed.

At this time, the aerobic tank 230 is a schematic cross-sectional view of the aerobic tank for nitrifying and denitrifying nitrogen as shown in FIG. 2 or 4, and is formed to remove untreated residual organic material in the anaerobic tank and the anaerobic tank.

These aerobic tanks consist of a multi-stage end and / or either end of each tank, a pH sensor, an ammonia nitrogen (NH ₄ -N) sensor, a nitrogen nitrate (NO ₃ -N) sensor, and an MLS (MLSS) sensor. , Dissolved oxygen (DO sensor) sensor is provided to form the residual nitrogen amount, and a separate circulation facility 231 is provided at the end of each tank to provide ammonia nitrogen (NH ₄ -N) to nitrate nitrogen (NO ₃ The nitric acid oxidized with -N) is formed to supply air to microorganisms while being circulated in an anoxic tank (selectively performed for the purpose of improving nitrogen removal efficiency).

Accordingly, the exhalation tank 230 is formed to further include a circulation facility 231 and a solids residence time management device 232.

That is, the circulation facility 231 is a process in which nitrification and denitrification of sewage by microbial treatment are performed simultaneously, and is configured to be at least three tanks, but the concentration of pH and dissolved oxygen (DO) in each divided compartmental aerobic tank is determined. After detecting the pH (pH) sensor and dissolved oxygen (DO sensor) sensor, it determines the amount of air that is suitable for the nitrification and denitrification area based on the set value, and increases or decreases the amount of air to increase the amount of air to the pH (pH) and dissolved oxygen (DO). ) It is formed to control the concentration.

At this time, the solids residence time management device 232 is provided at the end of the partitioned aerobic tank to detect the solids residence time based on the MLS sensor value and then drive the pump by the operation control device 410 to the sludge. It is formed to promote circulation.

Thus, the circulation facility 231 of the exhalation tank 230 is for supplying air to the microorganisms. It is capable of spraying fine air bubbles or ultra fine air bubbles to improve the delivery efficiency of oxygen and increase the energy saving effect (231- 1) and an air diffuser (231-2) is preferably further provided.

In other words, the aerobic tank is oxidized to nitrate nitrogen by the nitric acid bacteria in the 'biological reaction tank comprehensive management system using ICT' nitrogen contained in the primary sediment effluent passing through the anaerobic tank and the anaerobic tank.

In addition, nitrate nitrogen is reduced by anaerobic bacteria in the activated sludge and removed by nitrogen gas as a hydrogen donor as an organic material adsorbed to the sludge or organic matter in the influent sewage in an aerobic tank.

In addition, a part of the mixed solution containing nitrogen oxidized at the end of the aerobic tank, such as the cyclic denitrification method, anaerobic, anaerobic, and aerobic methods (the nitric acid circulating rate is about 40% to 100%) is circulated to the anoxic tank and denitrified. In addition, nitrate nitrogen contained in the return sludge of the secondary sediment is also partially denitrified in the anaerobic tank.

In this case, the aerobic tank is the ammonium nitrogen (NH ₄ ⁺⁾ in aerobic conditions the nitrate nitrogen (NO ₃ ^-) so that the bar can be a nitride, the reaction is as follows.

* ^{_{Nitrification: NH 4 + + 3 / 2O}} 2 NO 2 - + 2H + + H 2 O

^{_{NO 2 - + 1 / 2O 2}} NO 3 -

Since the aerobic tank simultaneously generates nitrification and denitrification by the 'Comprehensive Management System for Bioreactors utilizing ICT', the unit tank of the aerobic tank consists of at least 3 trillion units for efficient progress of nitrification and denitrification, and the residence time of the aerobic tank is 7 hours to 7 hours. It is desirable to make it 8 hours.

In addition, the NH ₄ -N, MLSS, pH (pH), dissolved oxygen (DO) sensor, and a computational control device for the overall management of the operation status of the aerobic tank include a 'biological reaction tank integrated management system using ICT' and the aerobic tank. It is configured to have an air supply device such as a blower and an air diffuser in order to supply the air necessary for the growth of microorganisms.

Thus, FIG. 5 is a schematic cross-sectional view of the circulation facility 231 for supplying air to the aerobic tank, wherein the circulation facility 231 is an air diffuser for energy saving of the aerobic tank, which accounts for about 40% of the total energy used in the sewage treatment plant. It is urgent to take measures to improve the oxygen transfer efficiency of the air supplied from the air.

To this end, by forming the particle size of the air supplied from the blower in the form of micro-bubbles or ultra-fine-strength bubbles, air diffuser piping (231-1) and air diffuser (Rapid air diffuser) can increase the air-to-water contact area to increase air delivery efficiency. 231-2).

At this time, the secondary sedimentation basin 300 is formed to precipitate and remove the floc generated in the aerobic tank by gravity, as shown in FIGS. 2 or 6 to 9, and to convey or draw sludge.

In addition, the secondary sedimentation tank 300 is formed with a sludge pit 310 to collect the precipitated sludge centrally.

In addition, the secondary sedimentation tank 300 is formed so that the sludge conveying device 320 is formed on one side of the sludge pit to transport the collected sludge to the front end of the anaerobic tank.

At this time, the secondary sedimentation basin is further equipped with an MLSS concentration meter 330 to measure the MLSS concentration, and after determining the SS concentration in real time, considering the optimality of the residence time of solids required for nitrification and the conditions for removing phosphorus, the amount of excess sludge required is a sludge concentration tank. A surplus sludge take-off device 340 for transferring to the furnace; It is formed to be further provided.

Accordingly, the secondary sedimentation basin 300 is highly filtered for contaminants including untreated organic substances, suspended substances, and phosphorus in the treated water as shown in FIG. 7 to be reused for river maintenance water or other purposes. The filtering device 350 is further formed.

That is, the filtration device is an organic material, floating material and contained in the treated water of the secondary sedimentation basin to efficiently reuse the limited water resources into river maintenance water, agricultural water, landscaping water, industrial water, road water and flush toilet water, etc. It is formed to form a floc by the coagulation reaction of phosphorus, etc., and then to perform high filtration treatment with water quality suitable for reuse.

In this case, the filtration device 350 is formed with a filter housing 351 to perform high-speed, high-precision filtration on the contaminants that have not been removed from the secondary sedimentation basin 300, and on the upper side of the filter housing 351 A filtered water supply pipe (351-1) is formed, and a discharge valve (351-3) capable of controlling the flow rate is formed while automatically controlling the filtered water discharge pipe (351-2) and the discharge flow rate on the lower side of the filter housing.

At this time, a multi-functional eco-friendly sand filter material 353 equipped with a backwashing device 352 is stacked by the strainer support 354 inside the filter housing, and communicates with the filtered water supply pipe 351-1 at the upper end of the filter housing. The cross-shaped trap (357) in the form of a cross is formed.

At this time, the filtration device 350 is provided with a water level sensor 355 and a backwash water outlet 356 on one side and the other side of the filter housing, and the eco-friendly sand filter material 353 stacked on the strainer support 354 is thick. The gravel layer and the fine sand layer are made to have upper and lower layers.

In addition, a side discharge valve 356-1 is formed on one side of the filtered water in order to discharge the filtered water generated in the backwashing process to the backwashed water outlet 356, and the backwashed water generated on one side end of the overflow trap 357 It is preferable that the backwashing water upper discharge valve 357-1 is formed in order to discharge it to the discharge port 356.

On the other hand, the strainer support 354 is to be provided with a plate panel 354-2 having a plurality of coupling holes 354-1 formed thereon, wherein the coupling hole 354-1 has a strainer member 354-3 assembled It is formed as possible.

At this time, the strainer member 354-3 is formed with a hollow tube 354-31, which penetrates through the coupling hole 354-1 and branches outwards at both ends of the plate panel 354-2, and the hollow tube ( 354-31) is formed with a thread on the outer circumferential surface so that the upper grille cone 354-32 and the lower tightening nut 354-33 are combined.

Accordingly, an air discharge plate 354-35 having an exhaust groove 354-34 is formed between the grille cone 354-32 and the tightening nut 354-33 to form a strainer member when high pressure air is introduced during backwashing. It is formed so that the exhaust grooves 354-34 are always discharged without remaining in (354-3), and is formed to prevent the loss of the multifunctional eco-friendly sand filter material 353 by not causing air bubbles during backwashing. .

To explain this in more detail, in the past, excess air was lost due to air remaining under the strainer member after backwashing with air in order to remove the suspended matter trapped in the filter medium.

That is, in the process of discharging the backwashing water, a problem occurred in which residual air at the lower part was discharged to the upper part together with the filter medium, and the strainer member had a wide eye (W = 1.5mm) and the basic filter material was gravel (5-10mm) and royal sand ( 2.5 ~ 5mm), causing some fine filter media to be lost through the lower support layer.

This is because the multi-functional eco-friendly sand filter media has a fine particle size of 0.4 to 1.4 mm, so that they are partially lost through the royal sand, gravel layer, and strainer.

Therefore, the conventional strainer member backwashes the filter medium with air and then flows the backwash water from the bottom to the top to float the filter medium, and then, in the process of stabilizing the filter medium, the floating material flows into the bottom of the filter medium and then flows back to the bottom during filtration. As the suspended material flows out for a certain period of time (5 minutes), the phenomenon that water quality deteriorates occurs.

The present invention is to improve this, and in the backwashing process, an exhaust groove, which is a structure capable of discharging residual air remaining under the strainer, is formed to prevent loss of media due to residual air.

To this end, the strainer member of the present invention has a strainer member because the previously installed strainer member has a snow neck of 1.5 mm, so that the filter material is leaked to the lower part of the strainer member because the multi-functional eco-friendly sand filter material has a particle diameter of 0.4 to 1.4 mm. It is formed to prevent the filter medium from being lost to the lower part when backwashing by forming the above-described exhaust groove while replacing the eye neck with 0.5 to 0.8 mm.

As described above, the filtration device is a down-flow filtration device in which the filtered water transferred from the secondary sediment is sent downward from the top, and is configured to be filtered while penetrating through a multi-functional eco-friendly sand filter medium.

On the other hand, if the filter layer structure of the filtration device is described in more detail, it is composed of a strainer support having a plurality of strainer members combined, a gravel layer, a coarse sand layer, a fine sand layer, and a multifunctional eco-friendly sand filter material.

At this time, the strainer member is sufficiently installed at regular intervals to prevent the gravel, coarse sand, fine sand, and multi-functional eco-friendly sand filter material seated thereon from leaking under the filtration layer and sufficiently discharge the filtered water to the outside. It is desirable to do.

Further, as described above, the strainer member is installed not only for the purpose of preventing the loss of gravel, coarse sand and fine sand, multifunctional eco-friendly sand filter material, but also moves air and backwash water evenly upstream when backwashing the filter layer. It also plays a role in helping.

Thus, under the strainer support, a discharge valve for discharging filtered water to the outside is installed. The discharge valve (351-3) has a flow control function that can automatically adjust the amount of filtered discharge according to the level of the filtered water and provides air for backwashing. It is desirable to have an air diffuser that can eject evenly and a device that supplies backwash water.

Thus, the backwashing device 352 of the filtration device 350 is to be provided on the lower side of the filtration enclosure 351, so that the high pressure air is injected into the air diffuser 352-12 by the blower 352-11 A backwashing device 352-1 is formed, and the pump 352-21 and the backwashing tube 322-22 are supplied to the lower other side of the filter housing 351 through the inverter for disinfection and discharge to receive backwash. It is preferable that the backwashing apparatus 352-2 having a) is further provided.

In more detail, if the filtered water is no longer filtered by contaminants to be laminated on a multi-functional eco-friendly sand filter material, if the filtration speed is slowed or the discharge amount is significantly reduced, the level of raw water in the precision filter increases.

At this time, the filtering device is formed to measure changes in the level and flow rate of the filtered water in the filter housing by means of any one sensor such as a wire-type water level meter or an ultrasonic water level meter.

For example, when the filtered water rises above a predetermined level, more specifically, when the filtered water level fluctuates, the sensor detects it and, on the other hand, sends the treated water filtered through the filtration layer to the outside through the water discharge pipe 351-2. do.

At this time, when the flow rate of the filtered water is measured in real time or irregularly, when the flow rate of the filtered water to be discharged along the water pipe does not reach the preset flow rate, the filtration process is stopped and the filtered water remaining in the filter housing is filtered. After discharging to the outside of the filter housing through the filtered water side discharge valve (356-1) and the backwash water outlet (356) installed on the side of the housing, the air and the reverse air flow upward from the bottom of the filter housing to the filter layer using a backwashing device. Supply wash water.

As an optional example, the backwashing facility is supplied with air first to completely separate the contaminants trapped in the multi-functional eco-friendly sand filter layer from the filter medium, and then supply backwashing water to provide the multi-functional eco-friendly sand filter material with the specific gravity difference between pollutants. A multi-functional, eco-friendly sand filter with a high specific gravity is first precipitated, and contaminants floating due to its light specific gravity are discharged to the outside of the filter.

In addition, the backwash water is injected in the opposite direction to the flow direction that is filtered by a pump having a structure capable of controlling the backwash supply flow rate by an inverter device, and the multifunctional eco-friendly sand filter material blocked by contaminants in the filter layer is topped. It is formed so as to prevent clogging of the filtration layer by separating the contaminants attached to the surface while dispersing with.

The contaminants peeled off by the backwashing float on the filtration layer portion and are discharged to the effluent storage tank after passing through the backwashing water upper discharge valve (357-1) and the backwashing water discharge port provided in the upper stream trap of the upper part of the filter housing. The discharge valve is installed at the end of the inlet trapping device so that the multi-functional eco-friendly sand filter material is not lost to the outside due to the vortex of the backwash discharge water.

At this time, if the air supplied during the backwashing process remains under the lower support of the filter housing, the residual air is discharged to the upper part of the filter layer during the discharge process of contaminants, and some of the multi-functional eco-friendly sand filter material is floated to the top and will be lost along with the discharged water. Therefore, the lower support strainer of the filter housing is provided with a groove-shaped cross-sectional structure capable of completely removing residual air to the top of the filtration layer during the backwashing water supply process.

In addition, an air volume control valve of an appropriate air amount increasing / decreasing device is installed in the air diffuser area divided by a vertical pipe, and the angle control of the air volume control valve installed in the vertical pipe performs the number and output control of the blower.

The pH (pH) sensor installed at the end of the aerobic tank is used as an index for the operation of performing nitrification denitration in the aerobic tank, and when the nitrification reaction proceeds in the aerobic tank, alkalinity is consumed and the pH (pH) is lowered.

In the 'integrated bioreactor management system using ICT', nitrification reaction occurs until the pH value reaches the set value, and the denitrification reaction proceeds when the pH value exceeds the set value.

On the other hand, Figure 10 is a schematic illustration of the operation control device of the 'integrated bioreactor management system using ICT'.

The configuration of the operation control device in the 'Comprehensive Management System for Bioreactors using ICT' is largely composed of an enclosure, an inner box, a CPU operation unit, an instruction unit, a power supply unit, an input unit and an output unit, and a peripheral device.

Accordingly, the enclosure protects the interior parts and protects them from being impaired due to moisture while protecting and protecting various parts.

At this time, the inner box is formed to install a CPU operation unit, an instruction unit, an input unit, an output unit and a peripheral device in the operation control device.

In addition, the CPU operation unit is formed to decode a program stored in the memory of the operation control device or to execute processing contents.

At this time, the indicator includes operating state values such as NH ₄ -N, MLSS, pH (pH), dissolved oxygen (DO) concentration, blowing amount, and valve angle calculated by the operation control device, nitrification step, denitrification step, etc. It is formed with letters and notifications on the front for display.

Accordingly, the power supply device is formed to supply power to each component of the operation control device.

At this time, the input unit is a part that detects the state of the external device to the operation control device or instructs the movement of the external device through an operation panel, and the electrical specifications are consistent with the external device, it is easy to contact the external device, and noise is generated from the external device. It is formed so as not to be transmitted to the CPU.

In addition, the output unit is a part that moves an external device or displays a state by transferring it to an electromagnetic contactor or solenoid connected to the outside of the operation control device, so that a transistor output dedicated to DC power is used in consideration of frequent opening and closing of the contact. Is formed.

Accordingly, the peripheral device is formed to record a program in the memory of the operation control device.

Accordingly, FIG. 13 shows a flow rate control flow chart for the pH value and dissolved oxygen (DO) value of the exhalation tank. When the pH value of the exhalation tank is lower than the set value, the blower is stopped and denitrification is performed. If the set value is set, the denitrification operation is performed while maintaining the current state of the blower at the current level. If the pH (pH) value is higher than the set value, the blower is operated to perform nitrification operation.

In addition, if the dissolved oxygen (DO) value of the exhalation tank is less than or equal to the lower limit of the set value, the operation of the blower is increased to operate, and if the value is set, the operation state of the blower is maintained at the current level, and the dissolved oxygen (DO) value is greater than or equal to the set value. If it is, operate after reducing the air supply for nitrification operation.

Thus, Figure 14 is an exemplary control panel of the nitrification and denitrification step of the exhalation tank, when the pH value of the exhalation tank moves above the set value, the valve angle by the nitrification proceeding instruction such as nitrification denitrification notification is opened to 100%, Dissolved oxygen (DO) actual value is 100% of 1st stage output (100% of airflow), 98% of 2nd stage output (90% of airflow), 96% of 3rd stage output The amount of blowing is increased or decreased in steps of 1 to 5 in steps of 80%), 4% output 94% (70% blowing), and 92% 5th output (60% blowing).

In addition, when the pH value moves below the set value, the valve angle by denitrification progress instruction such as nitrification denitrification notification is closed to 20%.

At this time, the amount of blown air supplies the minimum amount of blown air required to stop and denitrify the blower regardless of the measured value of dissolved oxygen (DO).
