摘要：
对利用酸改性粉煤灰与超纯磁铁矿粉复配物对生活污水化学强化一级处理并通过磁场将絮体收集进行了研究, 结果表明:经浓盐酸改性的复配物, 在粉煤灰用量为120 mg/L, 超纯磁铁矿粉用量为60 mg/L的情况下, 对水体浊度、COD、总P去除效果最佳, 所成絮体磁响应性强, 移出速度快。最后, 对其机理进行了初步探讨。

Abstract:
It is studied that the compound, which is made from modified and fly ash and ultra-pure magnetic ore powder, has been used in the chemically enhanced primary treatment(CEPT)of domestic sewage. The flocculant has been collected through the magnetic field. The results show that when the dosage of the fly ash of the compound, which has been modified with concentrated hydrochloric acid, is 120 mg/L, the dosage of the ultra-pure magnetic ore powder is 60 mg/L, the efficiencies of the water body turbidity, COD and removal rate of total phosphorus are the best. The flocculant magnetic response is the strongest. And the removal speed is the fastest. At the end, its mechanismis discussed primarily.
