实验室采用抚顺石油化工研究院富集培养的硝化细菌对某煤气化过程中产生的废水进行生物法深度净化处理研究。在碳氮比为2∶1条件下，当进水 COD 浓度为526 mg/L、氨氮浓度为164 mg/L 时，经4～5小时生物处理后出水 COD 平均浓度为45 mg/L、氨氮平均浓度为4.7 mg/L、总氮平均浓度为4.8 mg/L。
實驗室採用撫順石油化工研究院富集培養的硝化細菌對某煤氣化過程中產生的廢水進行生物法深度淨化處理研究。在碳氮比為2∶1條件下，噹進水 COD 濃度為526 mg/L、氨氮濃度為164 mg/L 時，經4～5小時生物處理後齣水 COD 平均濃度為45 mg/L、氨氮平均濃度為4.7 mg/L、總氮平均濃度為4.8 mg/L。
실험실채용무순석유화공연구원부집배양적초화세균대모매기화과정중산생적폐수진행생물법심도정화처리연구。재탄담비위2∶1조건하，당진수 COD 농도위526 mg/L、안담농도위164 mg/L 시，경4～5소시생물처리후출수 COD 평균농도위45 mg/L、안담평균농도위4.7 mg/L、총담평균농도위4.8 mg/L。
Wastewater from coal gasiifcation is bio-treated in a pilot plant which includes 2 stirring reactors and 3-phrased aeration. Setting C/N at 2:1 and with COD concentration at 526 mg/L, ammonia concentration at 164 mg/L and the total salt content at 1 600 mg/L in the inlfuent, after 4 hours of nitrobacteria processing, in the eflfuent the average concentrations of COD, ammonia and TN are reduced to 45 mg/L, 4.7 mg/L and 4.8 mg/L respectively, the total hardness is reduced to166.3 mg/L from 934 mg/L, and the total salt content is reduced to 925 mg/L. The eflfuent properties all meet requirements for water reuse.
