| 摘 要： | 为探讨曝气生物滤池进水COD浓度对NH3-H去除效果的影响,选取污水厂现场进行实地研究。将反应器进水COD浓度划分为5个水平:70~90 mg/L、90~110 mg/L、110~130 mg/L、130~150 mg/L、>150 mg/L,测定上述各个水平下的NH3-N去除率并进行反正弦转换后,做单因素方差分析。结果表明,在一定的水力负荷条件下,进水COD浓度与NH3-H的去除率密切相关,当进水ρ(COD)<90 mg/L和>150 mg/L时,NH3-H去除率较低;而当进水ρ(COD)为90~110 mg/L时,NH3-H去除率较高。

| Abstract: | It is selected Shenyang Xiannhe Wastewater Treatment Plant as research site to investigate the effects of influent COD concentration on NH3-H removal rate in a biological aerated filter.By dividing the influent COD concentration into 5 levels: 70~90 mg/L,90~110 mg/L,110~130 mg/L,130~150 mg/L and over 150 mg/L respectively,it is tested the NH3-H removal rate under each condition and done one-way analysis of variance.The results indicated that influent COD concentration is closely related to NH3-H removal rat... |
