摘　　要：采用冬、夏两季15个24 h周期的数据,对常州某居民楼宇人均日生活污水排放量、人均日生活污水污染物产生量和污染物排放浓度的季节变化特征开展了研究。结果表明,被测试楼宇居民人均日生活污水排放量的季节变化不明显,冬季、夏季的平均值分别为237.38和243.33 L/(人·d);人均日生活污水污染物产生量、污染物排放浓度和浓度比值均呈现冬季较高、夏季较低的变化规律,人均日COD、BOD5、NH3-N、TN和TP产生量的冬季平均值分别为130.97、68.87、10.24、17.10和1.62 g(/人·d),夏季平均值分别为119.10、47.55、8.94、13.50和1.45 g(/人·d);以上指标排放浓度的冬季平均值分别为552.01、287.79、43.59、72.28和6.86 mg/L,夏季平均值分别为491.26、196.42、37.25、55.76和5.96 mg/L;BOD5/COD、BOD5/NH3-N、BOD5/TN和BOD5/TP的冬季平均值分别为0.52、6.87、3.99和42.07,夏季平均值分别为0.40、5.33、3.52和32.99。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.
