[Problems to be Solved by Prior Art and Invention]

 Conventionally, sewage discharged from livestock houses, etc. is treated using various types of sewage treatment methods such as water purification treatment methods and soil infiltration treatment methods.However, with the above treatment methods, pollution of rivers, soil, groundwater, etc. There is a horror. Therefore, a so-called sewage evaporation processing system is proposed in which sewage is sprayed into the processing chamber where the outside air is blown and the sprayed sewage is evaporated from the evaporation port of the processing chamber. However, in the wastewater evaporative treatment system, the amount of evaporation varies greatly depending on atmospheric conditions such as humidity and temperature, so the system cannot operate when the outside air humidity is high, such as in the case of rain. However, there was a drawback in that the operating time was greatly affected by the weather, etc., and the processing amount fluctuated significantly.

[0003]

[Means for Solving the Problems]

 The present invention was devised with the object of providing a sewage evaporative treatment system capable of eliminating these drawbacks in view of the above-mentioned circumstances. A treatment chamber having an evaporation port and a treatment chamber having the same are provided. What is claimed is: 1. A sewage evaporation treatment system comprising a blower for sending air to a treatment chamber and a spraying device for spraying treated sewage into a treatment chamber, wherein the sewage evaporation treatment system heats the treatment chamber or treated sewage. It is characterized by having a device attached. The present invention, with this configuration, enables the sewage evaporation treatment system to always be operated smoothly regardless of atmospheric conditions and to significantly improve the treatment capacity.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a vinyl house that constitutes a sewage evaporative treatment system. The vinyl house 1 is formed in a tunnel shape having a predetermined total length. An evaporation port 1a having an area is formed.

Reference numeral 2 denotes a spray nozzle provided at the start end of the vinyl house 1, and the spray nozzle 2 decomposes sewage supplied from a storage tank 3 described later into extremely fine particles to enter the vinyl house 1. It is to be sprayed. In other words, in the present embodiment, wastewater such as manure discharged from the livestock shed 4 is temporarily stored in the storage tank 3 and solid matter is removed by an appropriate means, and then pumped to the spray nozzle 2 by the pump 5. It is configured to supply.

Further, 6 is a fan provided at the start end of the vinyl house 1, and the fan 6 is provided in order to promote evaporation of the finely sprayed wastewater into the atmosphere. The outside air is forced to be sent inside. That is, fine particulate waste water and the outside air are supplied into the vinyl house 1, and the waste water evaporated in the outside air is discharged to the outside of the vinyl house 1 through the evaporation port 1a.

Furthermore, 7 is a heating device provided outside the starting end side of the vinyl house 1, and the heating device 7 heats the inhaled outside air and heats the outside air at the vinyl house 1 It is designed to be supplied inside. That is, when the inside of the vinyl house 1 is heated by the warming device 7, the relative humidity inside the vinyl house 1 can be lowered and evaporation of sewage can be remarkably promoted. It is possible to operate the sewage evaporation treatment system even in a high condition.

On the other hand, 9 is a control unit of the sewage evaporation treatment system, and the control unit 9 is configured by using a so-called micro computer (including CPU, ROM, RAM, etc.). From the automatic operation switch 10 for switching between the automatic operation and the manual operation, the humidity sensor 11 arranged below the evaporation port 1a of the vinyl house 1, the tank sensor 12 for detecting the storage amount of the storage tank 3, and the like. While inputting a signal, an operation signal is output to the spray nozzle 2, the pump 5, the fan 6, the heating device 7 and the like based on the determination based on these input signals. That is, a control program for automatically controlling the operation of the sewage evaporation treatment system is stored in the control unit 9 in advance, and the control procedure of the control program will be described below based on the flow chart.

In the state where the control program is activated, first, the state of the automatic operation switch 10 is judged, and if it is OFF, the manually operated control routine defined separately is executed, while the automatic operation switch 10 is ON. In this case, subsequently, after confirming the storage amount of the storage tank 3 based on the detection of the tank sensor 12, the spray nozzle 2, the pump 5 and the fan 6 are operated to operate the wastewater evaporation processing system. Prior to that, the judgment humidity of the humidity sensor 11 and the preset humidity S are compared and judged. When it is determined that the detected humidity Sk is lower than the set humidity S, the heating device 7 is stopped and the evaporation process is performed at room temperature, while when the detected humidity Sk is equal to or higher than the set humidity S, The temperature device 7 is operated to automatically lower the relative humidity in the vinyl house 1.

In the embodiment of the present invention configured as described above, sewage made into fine particles by the spray nozzle 2 and forcedly sent by the fan 6 into the vinyl house 1. Although the outside air is supplied and the water content of the wastewater supplied into the vinyl house 1 is evaporated into the outside air and discharged to the outside from the evaporation port 1a formed in the ceiling part of the vinyl house 1, When the humidity is high due to rainfall or the like, the inside of the vinyl house 1 is heated based on the automatic operation of the heating device 7, and in this state, the relative humidity inside the vinyl house 1 decreases and the evaporation process continues. You will get it. Therefore, even though the wastewater is vaporized, the system can be operated even when the outside air humidity is high.As a result, the disadvantage that the operating time is greatly affected by the weather etc. is eliminated and the processing capacity is greatly increased. Can be improved.

In addition, in the embodiment, since the heating device 7 is automatically turned on and off based on the detection of the humidity sensor 11, it is permissible to manually operate each time, or the heating device 7 is wastefully used. It is possible to eliminate the inconvenience of driving and save heating energy.

In addition, the present invention is not limited to the above-mentioned embodiment, and for example, the waste water is heated without heating the inside of the processing chamber to promote the evaporation of the waste water. It is also good. Further, as the heating means, it is also possible to use exhaust heat from a factory or the like, as shown in the second and third embodiments, without providing a dedicated heating device as in the above embodiment. That is, the second embodiment is configured to supply the heat exhausted from the food factory 13 to the fan 6 to heat the inside of the greenhouse 1, and the third embodiment is used for the food factory. The warm waste water discharged from 13 is supplied to the heat exchanger 14, and the waste water is heated by the heat exchanger 14. In such a structure, waste heat and warm waste water can be effectively used. This is not acceptable, and there is an advantage that operating costs can be significantly reduced by eliminating the need for heating fuel.

[Operation effect]

 In summary, since the present invention is configured as described above, it heats the treatment room or the treated wastewater while spraying the wastewater into the treatment room into which the outside air is sent to evaporate the wastewater. Since it is equipped with a heating device that heats up, it is possible to accelerate the evaporation of sewage water by heating the treatment chamber or sewage water based on the operation of the heating device, even in the temporary high humidity state. That is, since the sewage evaporation treatment system can be operated regardless of atmospheric conditions, it is possible to eliminate the drawback that the operating time is greatly affected by the weather and the like, and it is possible to always treat sewage with a stable treatment capacity.
