Characteristics of pollutant loads and water quality, and the relation between water quality of the influent and the effluent were investigated for domestic wastewater treatment facilities, which were designed for 51 persons or more and have long inflow pipeline. It was found that average values of pollutant loads were 243l for water quantity, 37.9g for BOD, 8.1g for T-N, and 1.0g for T-P per capita per day, and non-excess probability 75% values of pollutant loads were 286l for water quantity, 44.2g for BOD, 9.1g for T-N, and 1.1g for T-P per capita per day. By the result of principal component analysis, the first component mainly characterized the total water quality, while the second component described the dissolved matters. It was also found that chlorine ion compensation was an effective method for analyzing water quality characteristics of domestic wastewater. On the other hand, the ratios of BOD to TOC and D-BOD to D-TOC in influent were both about 1.5, while the ratios of C-BOD to TOC and D-BOD to D-TOC in effluent were 0.61 and 0.34 respectively. These results indicated that there was a given quantity of organic matters, which dissolved in the effluent and were not detected in BOD analysis. When the effluent T-N was under 20mg · l-1, the effluent D-COD and D-TOC were under 10mg · l-1. It was suggested that D-COD and D-TOC may be utilized as organic carbon source in nitrogen removing.
