摘要
针对雨水调蓄池进水水量波动大、氨氮浓度偏高、COD浓度偏低的特点,采用改良曝气生物滤池工艺进行处理。试验结果表明:进水COD质量浓度从84 mg/L以内下降到44 mg/L以下,氨氮质量浓度从5.3-24.4 mg/L下降至0.09-1.20 mg/L,TP质量浓度从0.08-1.36 mg/L下降到0.04-0.40 mg/L,改良曝气生物滤池工艺对COD、氨氮、TP等去除率分别约为33.5%、96%、55%,出水水质达到GB 3838—2002《地表水环境质量标准》Ⅴ类标准。
According to the characteristics of rainwater storage tank such as:large fluctuation of water quantity,high concentration of ammonia nitrogen,low concentration of COD and so on,an improved biological aerated filter process was adopted for its treatment.The experimental results showed that;the mass concentration of COD in influent water decreased from not above 84 mg/L to below 44 mg/L,the mass concentration of ammonia nitrogen decreased from 5.3-24.4 mg/L to 0.09-1.20 mg/L,the mass concentration of TP decreased from 0.08-1.36 mg/L to 0.04-0.40 mg/L.The removal rates of COD,ammonia nitrogen and TP by the said modified biological aerated filter process were 33.5%,96%and 55%respectively,the effluent water quality met the requirement of class V of GB 3838—2002 Surface water environmental quality standard.
