碩士 === 逢甲大學 === 環境工程與科學所 === 98 === Abstract This study based on the principle of the soil absorption system, improving the previous of soil absorption system module design, and set up the soil columns in laboratory to campus sewage water using the peristaltic pump batch to explore the system on the pollutant effect. And test the different concentrations, different pre-treatment aeration and interrupt sources into the water to provide treatment effect on the system. In the results of showed that for 785 L /d aeration, the soil columns had good nitrogen removal occurs in anaerobic ammonium oxidation. the column 1 removal efficiency as high as 99.21%, the column 2 pre-processing efficiency as high as 97.64%, post-processing efficiency was about 29 ~ 60%, the column 3 pre-processing as high as 99.52%, post-processing efficiency is about 80%. BOD also has been removed, the column 1 about 85%, the column 2 about 70%, the column 3 about 78% removal efficiency. The second phase of adjust the aeration capacity of 131 L/d on the whole of BOD, the soil columns removal rates were 77%, 72% and 64%. The removal rates were slightly down. Be lowered after aeration, the removal efficiency of TN decreased to 28% and 38%. The nitrification decreased that the resulted in poor. The aeration capacity increased to 262 L /d, the system has recovered nitrification. Nitrogen removal efficiency increased to 49%. The system of nutrient supply disruption, the resulted can not be recovery. The system to re-string domestication, that deploy high concentration of nitrogen wastewater, the aeration was 262 L /d. soil columns TN removal efficiency of about 57%, 82% and 77%. Comprehensive experimental results, improved the system module design that efficiency of nitrogen removal having improved significantly, BOD removal was also a considerable effect. Applied on high concentrations in wastewater to the feasibility of high, but permeability control is not easy. The system can consider C/N values to control, achieve to removal the high pollutants.
