The control device 9 performs the operation of the manure processing device of the present invention and the accompanying control based on the instruction from the controller 8.

Next, a method of controlling the aeration treatment tank of the manure processing apparatus of the present invention will be described with reference to FIGS. 1 and 7. The excrement fluid supplied to the pre-storage tank 5 is sent to the first aeration processing tank 1. In the first aeration processing tank 1, aeration processing is performed as shown in the flowchart of FIG.

First, the controller 8 uses the level sensor 2
Based on 04, it is detected whether or not there is a predetermined amount of manure fluid in the first aeration processing tank 1 (step S1). When the amount of manure fluid in the first aeration processing tank 1 is less than the predetermined amount (step S1: NO), the controller 8 drives the pump 86 of the pre-storage tank 5, and the valves 111, 112, 113, 1
By adjusting 14,134,140,141,
The manure fluid in the pre-storage tank 5 is supplied to the first aeration processing tank 1 (step S7). When the manure fluid in the first aeration processing tank 1 satisfies a predetermined amount (step S1: YE
S), the controller 8 drives the aerator 16 and the air supply device 17 that realize the air supply means (step S2), and performs the aeration process on the excrement fluid.

When air is supplied to the excrement fluid from the air supply means, oxidative fermentation of microorganisms in the excrement fluid is promoted,
A large amount of bubbles are generated inside the aeration treatment tank. If such an aeration process is performed excessively, the air supplied from the air supply means and the gas generated by the oxidative fermentation of microorganisms in the manure fluid will increase the pressure inside the aeration process tank. It is dangerous because the tank may burst. On the other hand, unless the air is sufficiently supplied to the excrement fluid by the air supply means, the oxidative fermentation treatment of the microorganisms in the excrement fluid is not promoted and the excretion fluid cannot be sufficiently aerated. Therefore, the control unit 8a controls the output device 1
When the flow rate (Q) of the defoaming water output from 3, 14 is within a predetermined range (Q ₀₂ <Q <Q ₀₁ ), the pH value of the excrement fluid in the first aeration treatment tank 1 is a predetermined value (S1 ) Is controlled so that each part of the first aeration processing tank 1 is continued. That is, when the flow rate of the defoaming water output from the output devices 13 and 14 exceeds Q ₀₁ (the upper limit value of the flow rate) (step S3: NO), the control unit 8a causes the inside of the first aeration processing tank 1 to operate. Since the aeration process is performed excessively, the aerator 16 and the air supply device 17 are stopped (step S8) to prevent the internal pressure of the first aeration process tank 1 from further increasing. Further, when the flow rate of the defoaming water output from the output devices 13 and 14 is lower than Q ₀₂ (lower limit value of flow rate) (step S4: NO), the controller 8 performs the oxidative fermentation process of the microorganisms in the excrement fluid. Since it has not been performed sufficiently, the aerator 16
When the air supply device 17 is stopped, the aerator 16 and the air supply device 17 are driven, and when the aerator 16 and the air supply device 17 are driven, the aerator 16 and the air supply device are continuously operated. 17 is driven (step S9). The reference values such as Q ₀₁ , Q ₀₂ and S1 are recorded in the memory 8b.

When the flow rate of the defoaming water output from the output devices 13 and 14 is within the predetermined range (steps S3 and 4: YES), the controller 8a refers to the pH sensor 201 to perform the first aeration process. The aeration process is performed until the pH value of the excrement fluid in the tank 1 reaches a predetermined value (step S5: NO). Then, when the pH value of the excrement fluid in the first aeration processing tank 1 reaches a predetermined value (step S5: YES), the controller 8a.
By driving the pump 20 and adjusting the valves 115 and 117, the manure fluid in the first aeration processing tank 1 that has been aerated until a predetermined pH value is second aerated by a predetermined amount. It is sent to the processing tank. The control unit 8a
The pH sensor 201 confirms that the pH value of the manure fluid inside the first aeration treatment tank 1 has reached a predetermined value, and after confirming that the pH value has been measured a predetermined number of times or for a predetermined time, the second aeration treatment tank 2 receives the manure fluid. Can also be sent.

The manure fluid sent to the second aeration tank 2 is controlled by the control section 8a in the same control method as described above.
The aeration process is performed until the predetermined pH value is reached. Then, in the second aeration treatment tank 2, the manure fluid that has been subjected to the aeration treatment until the predetermined pH value is reached is sent to the first aging tank 3 in a fixed amount.

In the present embodiment, the BOD value may be used instead of the above-mentioned pH value as the parameter used for controlling the aeration processing in the aeration processing tank.
The BOD (Biochemical Oxygen Demand) value represents the amount of oxygen consumed because organic pollutants in water are biochemically oxidized by aerobic microorganisms in water. In this case, a sensor for detecting the BOD value is provided inside the aeration treatment tank, and an aerator or an aerator is installed so that the flow rate of defoaming water output from the output device falls within a predetermined range until the BOD value reaches a predetermined value. The air supply means such as the air supply device and the heating device such as the heating pipe may be controlled. Regarding a specific method, the predetermined pH value in step S5 of FIG. 6 may be replaced with a predetermined BOD value, and thus detailed description thereof will be omitted.

Further, in the present embodiment, the COD value may be used instead of the above-mentioned pH value as the parameter used for controlling the aeration processing in the aeration processing tank.
This COD (Chemical Oxygen Demand / chemical oxygen demand) value represents the amount of oxygen consumed when mainly organic pollutants in water are treated with oxidizing substances. In this case, a sensor for detecting the COD value is provided inside the aeration treatment tank, and an aerator or an aerator is installed so that the flow rate of the defoaming water output from the output device falls within a predetermined range until the COD value reaches a predetermined value. The air supply means such as the air supply device and the heating device such as the heating pipe may be controlled.
As for a specific method, the predetermined pH value in step S5 of FIG. 6 may be replaced with a predetermined COD value, and thus detailed description thereof will be omitted.

Further, in the present embodiment, as the parameter used for controlling the aeration treatment in the aeration treatment tank, electric conductivity can be used instead of the above-mentioned pH value. This electric conductivity represents the degree of turbidity of impurities in the manure fluid. In this case, a sensor for detecting the electric conductivity of the manure fluid is provided inside the aeration treatment tank, and the flow rate of the defoaming water output from the output device falls within the predetermined range until the electric conductivity reaches a predetermined value. Thus, the air supply means such as the aerator and the air supply device and the heating device such as the heating pipe may be controlled. As for a specific method, the predetermined pH value in step S5 of FIG. 6 may be replaced with a predetermined electric conductivity, and thus detailed description thereof will be omitted.

In the present embodiment, the values used to control the aeration process in the aeration treatment tank are the above-mentioned flow rate, the temperature of the manure fluid inside the aeration treatment tank, and the pressure inside the aeration treatment tank. At least one of them can be used in combination. In this case, air supply means such as an aerator or an air supply device, or a heating device such as a heating pipe may be controlled so that the temperature and pressure inside the aeration treatment tank fall within a predetermined range. The configuration of this control method is shown in FIG. Figure 8
FIG. 6 is a block diagram showing another example of control of the aeration treatment tank.

The first aeration tank 1 has a flow sensor 202.
In addition to the above, a pressure sensor that measures the pressure inside the first aeration treatment tank 1 and a temperature sensor 203 that measures the temperature of the manure fluid inside the first aeration treatment tank 1 are provided. The flow rate sensor 202, the pressure sensor, and the temperature sensor 203 are electrically connected to the controller 8, and the values measured by each sensor are output to the controller 8. The controller 8 provides a predetermined range for the values measured by the flow rate sensor, the pressure sensor, and the temperature sensor, and the control device 9 and The aeration device 16 and the like are controlled to perform the aeration process until the manure fluid has a predetermined parameter value. It should be noted that the temperature sensor 203 and the pressure sensor are provided at any location where the temperature of the manure fluid inside the aeration treatment tank or the temperature inside the aeration treatment tank can be measured.
It can be provided at any position in the first aeration treatment tank 1.

The controller 8 sets the value measured by the pressure sensor to the value measured by the pressure sensor so that the pressure inside the first aeration treatment tank 1 is aerated until the parameter value of the manure fluid reaches a predetermined value. An upper limit value and a lower limit value are provided, and when the pressure exceeds the upper limit value, the air supply means such as the aerator 16 is stopped, and when the pressure inside the first aeration processing tank 1 falls below the lower limit value, the air supply for the aerator 16 etc. Drive means. Further, the controller 8 temperature sensor 20 so that the aeration process is performed within the predetermined range of the temperature of the manure fluid in the first aeration treatment tank 1 until the parameter value of the manure fluid reaches a predetermined value.
The upper limit value and the lower limit value are set in the value measured in 3, and when the temperature exceeds the upper limit value, the air supply means such as the aerator 16 and the heating means are stopped, and the temperature of the manure fluid inside the first aeration treatment tank 1 Is less than the lower limit value, the air supply means such as the aerator 16 and the heating device such as the heating pipe are driven. By combining these control methods described above with the control method using the flow sensor shown in FIG. 7, the manure processing apparatus according to the present embodiment performs stable aeration processing on the manure fluid and has a predetermined characteristic. It is possible to obtain an aeration-treated manure fluid having

The control method described above with reference to FIG. 8 can also be applied to the second aeration treatment tank 2.

The controller 8a controls the pH sensor, flow rate sensor, temperature sensor, pressure sensor, BOD value sensor, CO
The measured value obtained by the parameter value measuring unit such as the D value sensor and the electric conductivity sensor is compared with the reference value recorded in the memory 8b to calculate the difference, and the aeration treatment tank is set based on the difference. It can also be controlled. The control unit 8a can smoothly control the aeration process in the aeration process tank by adjusting the amount of air supplied by the air supply unit according to the degree of the difference.

The memory 8b has a pH sensor, a flow rate sensor, a temperature sensor, a pressure sensor, a BOD value sensor, and C.
A plurality of reference values corresponding to the measured values obtained by the parameter value measuring units such as the OD value sensor and the electric conductivity sensor are recorded, and the control unit 8a controls the pH sensor, the flow rate sensor, the temperature sensor, the pressure sensor, the BOD. The measured value obtained by the parameter value measuring unit such as the value sensor, the COD value sensor and the electric conductivity sensor is corrected by multiplying the reference value, and the control is performed based on the corrected value. You can also Thus, the manure processing apparatus according to the present embodiment, according to the state of the manure fluid in the aeration treatment tank, adjust the amount of air supplied by the air supply means and adjust the driving time, etc. The aeration process can be effectively performed on the excrement fluid.

The reference value recorded in the memory 8b was obtained by a parameter value measuring section such as a pH sensor, a flow rate sensor, a temperature sensor, a pressure sensor, a BOD value sensor, a COD value sensor and an electric conductivity sensor. It can be calibrated on the basis of the average value of the measured values at different time points. The measured value measured by the parameter value measurement unit is
Depending on the characteristics of the excrement fluid and the state of the aeration process in the aeration treatment tank, it may vary depending on the time of measurement, that is, the state of the excrement fluid near the sensor of the parameter value measuring unit at the time of measurement. Therefore, the control unit 8a calculates the average value of the measurement values at different time points and controls the air supply means and the like based on this average value. It should be noted that the memory 8b stores measurement values at different time points measured by the parameter value measuring unit, and the control unit 8a corrects the reference value based on the measurement values at different time points recorded in the memory 8b. . As a result, the manure processing apparatus of the present invention can perform stable aeration processing on the whole manure fluid.

Further, the shower 15 is the first aeration processing tank 1
In order to promote the oxidative fermentation of the manure fluid by outputting the manure fluid at the bottom from above the liquid surface of the first aeration treatment tank 1 and contacting with the air, air is supplied similarly to the aerator 16 and the air supply device 17. It can also be driven as a means. Thereby, the excrement fluid is effectively aerated. Needless to say, also in the second aeration treatment tank 2, the shower can be driven as the air supply means.

Next, the operation of the manure processing apparatus of the present invention will be described. Manure excreted by livestock is separated into a solid component and a liquid component by a commonly used solid-liquid separator. Next, the liquid component (manure and urine fluid) is charged into the front reservoir 5a inside the box 48 through the charging port 83 provided in the upper portion of the front reservoir 5. The pH value of the manure and urine fluid put in the pre-storage tank 5 is about 5.0 to 7.0. In the present embodiment, the operation will be described by using the pH value as the parameter value. However, instead of the pH value, the BOD value, C
It goes without saying that the OD value or the electric conductivity can be applied. In addition, the parameter values include pH value, BOD value, COD
It is also possible to combine at least two of the values or the electrical conductivities.

Since the manure fluid put into the front reservoir 5a has just been solid-liquid separated, residual solid matters are mixed in the manure fluid and the viscosity thereof is high. Therefore, the front reservoir 5a
The manure and urine fluid introduced in the above is stirred by the mixer 84. By doing so, the liquid component in the excrement fluid and the residual solid-liquid substance in the excrement fluid are agitated to reduce the viscosity, and the subsequent aeration treatment is effectively performed. Further, since the partition wall 82 has the hole 82a, the manure fluid passes through the hole 82a when being agitated by the mixer 84, and is more effective by moving between the front storage part 5a and the front storage part 5b. Is stirred.

As described above, the excrement fluid which is put into the pre-reservoir 5 and agitated by the mixer 84 passes through the pipe 86b and the pipe 12a by the pump 86,
It is delivered to the manure fluid diffusing unit 12 of the aeration treatment tank 1.

The manure fluid sent from the front storage tank 5 is drawn from the pipe 12a of the manure fluid diffusing section 12 into the drawing pipe 12b.
It passes through the inside, and from the lower end of the lead-in pipe 12b to the diffusion plate 12
It is released toward c. The excrement fluid colliding with the diffusion plate 12c rotated by the motor 12d effectively diffuses inside the aeration processing unit 1a. As a result, it is possible to prevent the excrement fluid discharged inside the first aeration treatment tank 1 from accumulating in one place, and the entire excrement fluid is effectively aerated.

The aeration processing section 1a by the manure and fluid diffusion section 12
The excrement fluid diffused inside is stored in the bottom of the aeration processing unit 1a, and aeration processing is performed by the aerator 16. At this time, the air is supplementarily supplied to the excrement fluid by the air supply device 17, so that the efficiency of the aeration process of the excrement fluid is improved.

When the manure fluid is subjected to aeration treatment, the manure fluid generates a large amount of bubbles. The bubbles pass through the cylindrical guide portions 13a, 14a of the output devices 13, 14 and the defoaming portions 13c, 1
4c, and is defoamed by the defoaming parts 13c and 14c to become a liquid, and passes through the outlet parts 13d and 14d to make the pipe 1
