摘要
研究了新型混凝剂BMT对城市污水进行强化混凝处理的效果,并与常用混凝剂聚合氯化铝(PAC)进行了比较。结果表明,在城市污水原水COD低于300mg/L和最佳工况下,经BMT处理后的出水能够达到《城镇污水处理厂污染物排放标准》(GB18918-2002)二级标准,并具备替代PAC的能力。
A new flocculent BMT which contains HumicAcid, is conducted to dispose municipal wastewater and compares with PAC. The results shows that under the chosen conditions, the municipal wastewater treated by BMT meet the 〈 GB18918- 2002〉 by the Second Level in COD, SS and TP when its total COD is below 300mg/L. It demonstrates that BMT could take the place of PAC as an effective flocculent.
