- Abstract:
- The seasonal variation of per capita daily sewage discharge, per capita daily domestic sewage pollutant production and pollutant discharge concentration of a residential building in Changzhou were investigated by using 15 periods of 24 h data in winter and summer. The seasonal variation of per capita daily domestic sewage discharge was not obvious, and the average values in winter and summer were 237.38 L/(cap·d) and 243.33 L/(cap·d), respectively. The per capita daily sewage pollutant production, pollutant discharge concentration and concentration ratio were higher in winter and lower in summer. The per capita daily productions of COD, BOD5, NH3-N, TN and TP in winter were 130.97 g/(cap·d), 68.87 g/(cap·d), 10.24 g/(cap·d), 17.10 g/(cap·d) and 1.62 g/(cap·d), respectively, and in summer were 119.10 g/(cap·d), 47.55 g/(cap·d), 8.94 g/(cap·d), 13.50 g/(cap·d) and 1.45 g/(cap·d), respectively. The average values of the above pollutant emission concentration were 552.01 mg/L, 287.79 mg/L, 43.59 mg/L, 72.28 mg/L and 6.86 mg/L in winter, and 491.26 mg/L, 196.42 mg/L, 37.25 mg/L, 55.76 mg/L and 5.96 mg/L in summer, respectively. The average values of BOD5/COD, BOD5/NH3-N, BOD5/TN and BOD5/TP were 0.52, 6.87, 3.99 and 42.07 in winter, and 0.40, 5.33, 3.52 and 32.99 in summer, respectively.
