本文通过以强化三采污水的预处理、减小或消除聚合物对混凝过程的影响为主要思路,考察了聚合物对水处理效果的影响,研究了减少聚合物对混凝效果影响的方法,并探讨了含聚污水的处理工艺。结果表明聚合物分子量越大对净水效果影响越明显,当聚合物含量大于5mg/L,对净水效果的负面影响明显;通过调节合适的pH,采用化学氧化预处理结合常规净水剂能取得较好的净水效果。
In this paper, the main idea is to reduce or eliminate the effect of polymer on the coagulation process by strengthening the pretreatment of the three mining wastewater, the impact of the polymer on the water treatment effect, the method to reduce the influence of the polymer on the coagulation effect , And discussed the treatment process of poly-polluted water. The results show that the greater the molecular weight of the polymer, the more obvious the effect of water purification effect, when the polymer content is greater than 5mg / L, the negative impact on water purification effect is obvious; by adjusting the appropriate pH, chemical oxidation pretreatment combined with conventional water purifier Get better water purification effect.
