This study has been conducted to provide basic information about treatment possibility of the evaporation rate analysis of livestock wastewater using the natural evaporation method. The results of this study could be summarized as follows:
Depending on whether the opening season (summer, autumn and winter), changes in evaporation of the open system at the vinyl house's. The open vinyl house system : The evaporation maximun deviation is 15.1 l/day at Free Water Surface and 17.6 l/day at RBCE. The closed vinyl house system : The evaporation maximum deviation is 8.4l/day at Free water surface and 10.5 l/day at RBCE.
Closed system applied in vinyl house due to a low temperature to prevent evaporation loss and the reduction of livestock wastewater odors caused by biological processes, and winter temperatures drop due to weakness of the activity of microorganisms is said to be sufficient in preventing the degradation is considered.
The evaporation rate range of the Free water surface evaporation and RBCE per unit area is alike 2.6 ~ 3.6 ℓ/m²/day, 2.6 ~ 3.7ℓ/m²/day respectively. Therefore the RBCE reduce a capacity rate one-hundredths compare with the Free Water Surface. It's possible to minimize the establishment site.
