1 is a block diagram illustrating an apparatus for managing a marine aquaculture management sewage in an embodiment of the present invention.

1, the marine aquaculture management sewage purifier includes sewage collecting unit 110, a slush settling tank 120, a transfer pump 121, a flow control unit 130, at least one aerobic reaction tank 421, 142 At least one anaerobic reaction tank 161 and 162, a sterilizing tank 170 and an efflux tank 180.

The sewage collection line 110 can determine the size of the average household tap water consumption by calculating the supply amount of ordinary domestic tap water. According to one embodiment, the sewage purifier for the marine farm manager is designed under the assumption that the supply amount of domestic household water satisfies the following conditions. Since the average rate of water 300cm ~ 400cm / sec (household water pressure is also ² ~ 3 kgf / cm 2), and the thickness of the water diameter 1.27cm (15A 1/2 inch) per second, the water coming out of the second 0.64x0.64x3. = 14x350 and ^{450cm 3 / sec = 450ml / sec} , this is coming out of the water per hour is 3600sec (1 ^{sigan) x 450cm 3 / sec = 1,620,000cm} 3 = 1.6TON. Therefore, the amount of water required per day is 1.6 TON / hour x 24 hours = 38 TON. Based on the average tap water usage rate of 250L / person, the average daily tap water usage time per day which meets 1 ton / day of generated water in the residence space of 4 persons is about 38 minutes based on the maximum flow rate (1.6 tons: 1 hour = 1 ton : 38 minutes) Water is used for an average of 13 minutes (= 38 ÷ 3) and 340 liters (= 1 ton ÷ 3) per day, three times a day, and the use interval is at least 4 hours Standard). An important factor in the problem of the purifier installed in the coastal facility is that it treats only sewage that is generated by a small number of users. This means that the amount of sewage introduced into the purifier is irregular.

According to one embodiment, the sewage 101 may be collected at the sewage collection station 110.

According to one embodiment, when the wastewater is delivered to the slush settling tank 120 from the sewage collecting unit 110, the slush settling tank can deposit the slush included in the sewage.

According to one embodiment, the transfer pump 121 may be used to deliver sewage, other than the slush, to the flow rate regulator 130. At this time, the flow rate regulating condenser 130 may include a filter membrane for removing the residual slush. According to one embodiment, the flow regulating condenser 130 may include a water level sensor for measuring the water level. At this time, the flow rate regulator can store about one ton of sewage. Flow regulating collection can be stored and uniformly supplied to the reactor even if the occurrence of sewage is not constant and occurs in the morning and evening of breakfast three times a day. Adjusting the flow rate can save the irregularly flowing wastewater to a size enough to store the wastewater generated on the first day, and supply an average of 41.7L of wastewater per hour to the first wastewater treatment facility. This is to distribute 1 ton of sewage generated in 1 day uniformly for 24 hours.

According to one embodiment, the transfer pump may include a float switch that floats when the level of the slurry settling tank rises, and operates the motor when the level of the slurry settling tank rises above a predetermined angle. At this time, the float switch operates the feed pump when the level of the slurry settling tank floats when the level of the slurry settling tank rises from the atmospheric angle, reaches the predetermined operating angle, and stops the operation of the feed pump when the level of the slurry settling tank decreases to the atmospheric angle again.

According to one embodiment, the aerobic reaction tank may be composed of four aerobic tanks, ie, first aerobic tank 141, second aerobic tank 142, third aerobic tank 143 and fourth aerobic tank 144. Each aerobic unit can store 188 liters of water. In the aerobic reaction tank, the organic substances contained in the sewage introduced from the flow control tank 130 can be decomposed using aerobic microorganisms. According to one embodiment, Bacillus bacteria of the Bacillus series may be used in the first, second, third, and fourth arrays. Bacillus is an aerobic bacterium that is well supplied with oxygen and rich in organic matter. It breaks down in 20-40 minute cycles and decomposes organics such as proteins and detergents in 5-12 hours. Decomposition residues include carbon dioxide and water.

According to one embodiment, the aerobic reaction tank may be supplied with air from the first air supply device 151 and the second air supply device 152. At this time, the first air supply device 151 may be a high-power air supply device. For example, the first air supply device 151 can supply 150 L / min of air at a power consumption of 130W. The second air supply device 152 may be a low-power air supply device. For example, the second air supply device 152 may be a noiseless pump that supplies 15 L / minute of air with a pump of 20 W power consumption.

According to one embodiment, the anaerobic tank may include a first anaerobic tank (161) and a second anaerobic tank (162). In the anaerobic reactor, anaerobic microorganisms can be used to decompose harmful substances in sewage, which have been decomposed by aerobic microorganisms. The first anaerobic tank (161) and the second anaerobic tank (162) are capable of decomposing organic substances in the sewage water by using Bacillus-based anaerobic bacteria.

According to one embodiment, the sterilizing tank 170 can sterilize pathogenic bacteria in purified sewage using ozone. At this time, the ozone generator 171 can receive ozone.

According to one embodiment, the discharge tank 180 can discharge dissolved ozone after sterilization treatment. At this time, in the discharge tank, the amount of residual ozone contained in the sewage can be minimized by waiting for about 4.5 hours.

According to one embodiment, the marine aquaculture sewage purifier can be installed in a living space to observe surrounding environmental factors, and can measure the progress of the reaction vessel in real time and purify efficiently. In particular, it is possible to detect at least one of temperature, light, time, and carbon dioxide, and to control the operation of the purification apparatus adaptively by measuring the reaction progress state in the aerobic reaction tank and the anaerobic reaction tank in real time. For example, when the manager senses that the sleeping state is established through a sensor that detects light and time, it is possible to deactivate the high-power first air supply device and activate only the low-power second air supply device. At this time, when only the second air supply device is operated, since the amount of air supplied is small, air can be continuously supplied. Since there is almost no use of water at bedtime and there is no occurrence of sewage, it may take a long time to purify the sewage. In addition, since the noise generated by the operation of the apparatus can be an obstacle to the sleeping, it is possible to use a noiseless pump (second air supply device) and to continuously operate in contrast to the control of the weekday time zone in order to increase the air supply amount. Since the degree of activation of the effective microorganisms is proportional to the total supply amount and the supply period, the treatment time per unit time is lower than that in the case of continuous supply of low power non-noise pump during the nighttime operation, There is no problem with the efficiency of.

According to one embodiment, when there is no nutrient (organic substance such as proteins contained in sewage) supplied to effective microorganisms, effective microorganisms can be induced into apo (spore) state to prevent the microorganisms from being killed. If such effective microorganisms are induced to apo-state, it is possible to reproduce again if necessary, and the sewage can be purified immediately. The microorganism must be added to the effluent without inducing the effective microorganism to the apo-state. If the additional input is not made, the organic wastewater containing uncleaned organic matter may be discharged. The induction of the apo-state can be determined by measuring the amount of carbon dioxide generated in the aerobic reaction vessels 141 to 144. At this time, refer to the ambient temperature. In other words, active microorganisms with high atmospheric temperature are active, so that more carbon dioxide can be generated in sewage containing the same concentration of organic matter than in winter. A decrease in the amount of carbon dioxide produced means that the activity of the effective microorganisms is poor and the organic content in the sewage is decreased. At this time, if carbon dioxide below a predetermined level is detected, air supply can be minimized to prevent the growth of effective microorganisms and induce apoptosis. By measuring the natural condition and time of the installation site of the purification device and the amount of carbon dioxide generated, it is possible to protect the user's residential environment and to maintain the best performance of the device.

Sewage entering the marine aquaculture system can be treated for 18 hours in an aerobic reactor, 9 hours in an anaerobic reactor, 4 hours and 30 minutes in a sterilization tank, and 4 hours and 30 minutes in an effluent tank.

2 is a view showing an input unit of a sewage purifier according to an embodiment of the present invention.

The input unit 200 of the sewage purifier may include a noise sensor 210, a water level sensor 220, a temperature sensor 230, an optical sensor 240, a real time clock 250, A timer and operation switch 260 and a carbon dioxide sensor 270. [

The noise sensor 210 can measure noise generated from the sewage purifier. According to one embodiment, when the marine farm manager is in the sleep state, the sewage purifier can be controlled so that the noise sensor 210 does not increase more than a certain noise level.

The water level sensor 220 can measure the amount of sewage water flowing in and the amount of sewage water remaining in the flow adjusting tank.

The temperature sensor 230 can measure the atmospheric temperature. According to one embodiment, when the atmospheric temperature falls below a predetermined temperature, even when the feed pump is not in operation, idling can be prevented to prevent freezing.

The optical sensor 240 can measure the brightness of the surroundings. According to one embodiment, it is possible to determine whether or not the marine farm manager is going to sleep by using the optical sensor.

A Real Time Clock 250 may provide a standard time to the sewage purifier. According to one embodiment, day and night can be distinguished through a real time clock.

The timer and operation switch 260 can receive an input command from the marine farm manager.

The carbon dioxide sensor 270 can determine the degree of reaction of the aerobic reaction tank and the anaerobic reaction tank. According to one embodiment, when carbon dioxide below the predetermined value is detected in the carbon dioxide sensor of the aerobic reaction tank, the operation of the air supply device is minimized, and the effective microorganisms can be induced to the apopto (spore) state.

According to one embodiment, the output of the sewage purifier comprises a first air supply control contactor 310, a second air supply control contactor 320, an ozone generator control contactor 330 and a display buzzer and lamp 340 ).

The sewage purifier can control the output unit 300 through a signal input from an input unit 200 (FIG. 2).

According to one embodiment, when the manager is in the sleep state through the optical sensor and the real time clock of the input unit, the first air supply device is deactivated through the first air supply device control contactor 310 of the output unit, The second air supply can be activated via the supply control contactor 320. [

4 is a view for explaining an actual implementation of a sewage purifying apparatus in an embodiment of the present invention.

The sewage purifier may be composed of a collection tank 410 and a system box 420.

According to one embodiment, the dust collector 410 may include a sewer collection and a slush settler.

According to one embodiment, the system box 420 includes a first aerobic tank 421, a second aerobic tank 422, a third aerobic tank 423, a fourth aerobic tank 424, a first anaerobic tank 425, A sterilization tank 426, a sterilization tank 427, and a discharge tank 428. At this time, the discharge tank 428 may include a discharge hose 429.

The configuration of Fig. 4 is for explaining an actual embodiment of the sewage purifying apparatus and may be configured in other forms. The role in each reaction tank is as described in Fig.

FIG. 5 is a diagram illustrating a circuit configuration of a sewage purifier for marine aquaculture farmers according to an embodiment of the present invention. Referring to FIG.

According to one embodiment, the circuitry of the marine aquaculture sewerage purifier may include a central processing unit 510, an input and an output.

The central processing unit 510 can use a generally used microcomputer.

The input unit includes a noise sensor 521 for measuring the ambient noise, an optical sensor 522 for measuring the ambient brightness, a water level sensor 523 for measuring the amount of sewage remaining in the inflow sewage amount and the flow rate adjusting house, A sensor 524, a RTC 525 providing standard time, a timer and operation switch 526, and a carbon dioxide sensor 527 for determining the degree of reaction of the aerobic and anaerobic reactors.

The output unit includes a first air supply device for supplying air to the aerobic reaction tank, control contactors 531 and 532 for controlling the second air supply device, an ozone generator control contactor 533 for controlling the sterilizing ozone generator, A buzzer and a lamp 534 for indicating the status.

6 is a view for explaining an electric wiring diagram of a sewage purifying apparatus for a marine farm manager according to an embodiment of the present invention.

According to one embodiment, a sewage purifier for a marine farm manager can use 220 VAC for general households. At this time, the low-power second air supply device 642 and the control circuit 644 such as a lamp and a buzzer can use a 12V battery power source 641 so that normal operation can be performed even during a power failure.

According to one embodiment, a domestic 220VAC power source may be supplied to the transfer pump 610, the first air supply 620, the ozone generator 630 and the battery charger 640. The battery charger 640 may be used to charge the battery 641 against power failure.

According to one embodiment, the transfer pump 610 for transferring sewage in the slush settling tank may be operated by operation of a self-attached float switch. For example, a float switch attached to a transfer pump may operate at an angle of approximately 45 to 90 degrees. When the level of the slush sedimentation tank is low, the float switch floats downward due to its own weight and floats when the water level rises. When the float switch floats and reaches a predetermined angle or more, an internal tilt switch is operated to operate the motor of the transfer pump 610. [ A float-activated switch can remain in operation until the float switch is fully down. That is, when the floating switch operates floating from the atmospheric angle, the feed pump can be operated until the water level is lowered to the atmospheric angle again. The transfer pump 610 is automatically operated when the sewage water in the slush settling tank is above a certain level, and does not operate if no sewage is generated. Therefore, there is no nighttime noise because the nighttime sleeping bed does not operate when there is no use of tap water. However, in order to prevent freezing of the winter pump, if the atmospheric temperature measured by the temperature sensor is maintained below a certain level, the pump can be frozen by rotating the pump for a predetermined period of time.

All output devices except the transfer pump can determine the operation time and operation time by referring to various sensor values in the central processing unit.

The sewage purifier for the marine farm manager can monitor the real-time sewage inflow rate, allow the noise generation at the time of day, measure the atmospheric temperature, judge freezing and freezing in the winter season, and monitor the operation status of the aerobic reactor.

The ozone generator 630 has little noise during operation and is not affected by freezing in winter. The ozone generator can be sterilized at regular intervals in conjunction with the operation of the first air supply device and the second air supply device according to the flow of sewage. The night noise and the degree of sewage purification depend on the operation of the first air supply vessel. The degree of noise generation can be measured with a noise sensor. The degree of progress of the purification can be determined by measuring the amount of generated carbon dioxide.

7 is a view for explaining a connection of a microcomputer of a wastewater purification apparatus for marine aquaculture farmers according to an embodiment of the present invention.

According to one embodiment, the microcomputer PIC16F73 can be used. Microcomputer PIC16F73 has analog input and digital input / output. Inside of the microcomputer is a built-in ROM and RAM for storing data. Input and output terminals can be selected and used. Analog input has 8 inputs (Bit) and 5 inputs. 5 analog inputs, 6 digital inputs and 8 digital outputs, and a serial communication port for wireless communication is set up separately. The communication port 720 is capable of direct connection of Bluetooth or ZigBee, which is general-purpose wireless communication means. The communication procedure and the communication speed were made to follow the standard of the general wireless communication. And transmits the status of the current device to the wireless communication.

Five analog input terminals are equipped with an 8-bit analog / digital (A / D) converter. The built-in A / D converter divides input voltage between 0VDC and 5VDC into 256 steps and can store the value. Table 1 summarizes the voltage input to the A / D converter as a digital value. The microcomputer interprets the sensor value with the converted digital value and performs the corresponding output. That is, the digital value 128 of the temperature sensor 734 is 25 ° C and the temperature is increased or decreased by 0.5 ° C when the digital value is increased or decreased by '1'. The digital value 128 of the noise sensor 731 is 50 decibels, and the noise level is increased or decreased by 0.2 decibels when the digital value is increased or decreased by '1'. The digital value 128 of the optical sensor 732 is 5000 lux, and the brightness degree when the digital value is increased or decreased by '1' is increased or decreased by 40 lux. The digital value 128 of the water level sensor 733 is 300 mm, and when the digital value is increased or decreased by '1', the water level is increased or decreased by 2.4 mm. The digital value of the carbon dioxide sensor 735 is 128 ppm, and the amount of carbon dioxide is 10 ppm. When the digital value is increased or decreased by 1, the amount of carbon dioxide is increased or decreased by 0.1 ppm. The digital inputs are simply high and low. The high level is divided into 4.5V - 5V, and the low level is divided into less than 0.7V.

The digital output is also made simple high and low. 4.7V - 5V for high, and 0.3V or less for low.

According to the embodiment, the night and day can be distinguished according to the signal of the RTC (clock) 756 inputted to the pin 6 of the microcomputer of the central processing unit. At this time, it is possible to further determine whether or not the camera is in the sleep state by receiving the value of the optical sensor 732 input by the third-pin analog AN1.

The first air supply control contactor 741, the second supply supply control contactor 742 and the ozone generator contactor 743 output circuit are connected to the first air supply (not shown) according to the output of the microcomputer It is possible to drive the apparatus, the second air supply apparatus, and the ozone generating apparatus. The drive can turn on the contactor connected to each output element. The coil of the contactor is driven at 12VDC and the current is about 200mA. The resistor R of the circuit supplies the voltage 5VDC of the output of the microcomputer (microcomp pins 21, 22, 23) to the base of the transistor. IB = (5VDC-0.7VDC) / R when R = VDC) / 4.7 K? = 0.91 mA. If the amplification degree of the transistor is 500, the allowable current IC = IB * hfe (amplification degree) = 0.91 mA * 500 = 455 mA for the collector of the transistor. Since the driving current of the contactor is 200mA, when 5VDC is output from the microcomputer, this signal is amplified by the transistor and the contactor controlling each output element is turned on.

The display buzzer and the lamp output circuit are connected to the display buzzer, the display lamp (in operation), the display lamp (sterilized), the display lamp ( Failure), and a display lamp (during conveyance). The buzzer for display and the display lamp can be light-on driven at a current of approximately 100 mA. The resistor R of the circuit supplies the voltage 5VDC of the output of the microcomputer (micom pins 24, 25, 26, 27, 28) to the base of the transistor. If the supply current IB = (5VDC-0.7VDC) / R and R = 4.7KΩ, IB = (5 VDC-0.7 VDC) / 4.7 K? = 0.91 mA. If the amplification of the transistor is 200, the allowable current IC = IB * hfe (amplification degree) = 0.91 mA * 200 = 182 mA for the collector of the transistor. Since the display buzzer and display lamp are approximately 100mA, when 5VDC is output from the microcomputer, this signal is amplified by the transistor and turns on each display buzzer and display lamp.

According to one embodiment, the sensor can use an output of 0-20 mV. Since the input of the analog terminal of the microcomputer is set to 0-5V, the required amplification of the operational amplifier is AV = 5V / 20mV = 250 times. The amplification degree of the operational amplifier is AV (R3 / R2) +1 or (R6 / R5) +1. The total amplification degree of 250 is divided into 25 * 10 in consideration of the stability of the circuit and amplified. 25 = (R 3 / R 2) +1 and 10 = (R 6 / R 5) +1. AV = [(24K? / 1K?) + 1] * [(9K? / 1K?) + 1] = 250 when R3 and R2 are set to 1K? And 24K? This value amplifies the maximum output voltage 20mV output from the sensor to the analog voltage 5V of the microcomputer. 20mV * 250 = 5V

According to one embodiment, four operation switches input high or low to the digital ports (microcomputers 11, 12, 13, and 14). 5V is normally supplied to the pin of the microcomputer through a resistor. When the switch is turned on, the 5V supplied to the pin of the microcomputer through the resistor is lowered to 0V, and a low level is inputted.

The timer, clock (RTC), Bluetooth or ZigBee according to one embodiment can be directly connected to the microcomputer without any additional circuit.
