生物转盘同步去除化学需氧量和氮的实验研究OA北大核心CSCDCSTPCD
COD and nitrogen removal with rotating biological contactor
采用单轴三级生物转盘(RBC),进行了生物转盘同步去除化学需氧量和氮的试验研究。水温度15℃,进水COD浓度为400mg/L左右时,转盘对化学需氧量的去除率达到85%左右。控制适宜的碱度,转盘系统氨氮的硝化率在75%左右、总氮(TN)的去除率在50%左右。增设硝化液回流系统后,总氮的去除率显著提高,特别是回流比为200%时,TN去除率在低温下可达73.87%。实验表明生物转盘对化学需氧量和氮有较好的同步去除效果。
A 3-stage rotating biological contactor was used to study simultaneous removal of COD and nitrogen.When temperature was 15 ℃ and influent COD concentration was about 400mg/L,removal rate of COD was about 85%.Through controlling proper alkalinity nitrification rate of ammonia was about 75% and removal rate of TN was about 50%.After addition of a nitrification liquid circulation system,removal rate of TN,at reflux ratio of 200% increased to 73.87 %.Experimenta…查看全部>>
