接触氧化技术在公园景观水体功能恢复中的运用试验研究

通过自行设计加工的试验装置，进行生物接触氧化技术在景观水体功能恢复中的试验研究。待处理的景观水体ρ(COD_Cr)为25~35 mg/L，ρ(NH₃-N)为2.2~3 mg/L，ρ(TP)为0.55~0.85 mg/L，有机负荷低，且水质变化幅度大。试验结果表明，在合适的运行参数下，生物接触氧化技术可以使经过处理的景观水体的ρ(COD_Cr)、ρ(NH₃-N)、ρ(TP)分别降至14.62 mg/L、0.26 mg/L、0.19 mg/L，满足地表水Ⅲ类水质标准，达到景观水体水质要求。

Examination and Study of Catalytic Oxidation in Sight Water Resumption

The experimental research about application of catalytic oxidation in sight water resumption has been carried out through our own test device. The slight water to be disposed has low organic capacity with large range of water quality and the concentration of COD_Cris in the range of 25-35 mg/L and 2.2-3 mg/L for NH₃-N and 0.55-0.85 mg/L for TP respectively. The experimental results show that at the suitable operating conditions biological catalytic oxidation could lower the concentration of COD_Cr, NH₃-N and TP to be 14.62 mg/L,0.26 mg/L,0.19 mg/L respectively to high extent, which is lower than the standard of Ⅲ class water quality and can meet the need of sight water.
