摘要
广州市城市污水属于典型的南方城市污水,污染物浓度不高.2000～2004五年间的监测结果表明:BOD5在30～200mg/L之间,COD在70～300mg/L之间,氨氮在10～40mg/L之间,总氮在10～40mg/L之间,总磷在1.5～5mg/L之间;可生化性较好,可生化性指数在0.35～0.75之间;生物脱氮除磷的潜力较大,其碳氮比和碳磷比的变化范围分别是:2～5以及20～60之间.
Guangzhou municipal wastewater, the typical southern one, has low waste concentration. According to the survey results of the five years between 2000 and 2004, BOD5 is between 30 and 200mg/L, COD between 70 and 300mg/L, ammonia nitrogen between 10 and 40mg/L, total nitrogen between 10 and 40mg/L, total phosphorus between 1.5 and 5mg/L, good biodegradability with indexes between 0.35 and 0.75 and huge potential of biological nitrogen and phosphorus removal, whose carbon--nitrogen ratio is 2 to 5 and carbon--phosphorus ratio is 20 to 60.
