This survey was performed to measure the concentration of pollutants in discharging water from nightsoil treatment plants in ChungNam area. This study was carried out quarterly on a season, 1996.
This summarized results were as follows ;
1. The measured concentration were BOD 1.4-160.0mg/l(average 21.7mg/l), SS 0.4-342.0mg/l(average 26.8mg/l), T-N 9.72-250.0mg/l(average 74.88mg/l), T-P 0.03-10.32mg/l(average 2.43mg/l) and E. Coli was unsuitable about 6.7%.
2. ADS (Aerobic Digestion System) and DES(Decompressed Evaporation System) + ADS is necessary to set the Suspended Solid removal equipment immediately.
3. LCS(Liquidphase Corrosion System) is necessary to set the Nitrogen removal equipment immediately.
