Therefore, in the inflow pipe 201, a discharge pipe 450 for treating and discharging the exhaust gas generated in the treatment process is disposed in the bottom / wastewater treatment plant, the food processing plant, the sludge treatment plant, the manure processing plant, If the concentration of the exhaust gas is high and the concentration meter 453 recognizes the concentration of the exhaust gas, the control unit 600 controls the inverter 700 to slow the speed of the blower 100 by the inverter 700 So that the supply rate of the exhaust gas flowing into the gas inlet pipe 201 is reduced.

 If the concentration of the exhaust gas is low, the concentration meter 453 recognizes the concentration of the exhaust gas and controls the inverter 700 so that the speed of the blower 100 is increased by the inverter 700 to flow into the inlet pipe 201 The supply speed of the exhaust gas is increased.

The present invention is characterized in that the exhaust gas generated in the treatment process is supplied to the blower 100 and the pretreatment cleaner 200 through the waste water treatment plant, the food waste treatment plant, the sludge treatment plant, the manure waste treatment plant, The first and second complex cleaning units 300 and 400 and the post-treatment unit 500 to easily collect the odor from the exhaust gas to remove ammonia gas, hydrogen sulfide, sulfur dioxide gas, nitric oxide gas Etc. can be removed, and the odor of complexity can be effectively removed.

It will be apparent to those skilled in the art that various modifications and equivalent arrangements may be made therein without departing from the scope of the present invention. . It is therefore to be understood that the invention is not limited to the form set forth in the detailed description.

Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims. It is also to be understood that the invention includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
