摘要
制备了重金属捕集剂WY5并用于含铬废水的处理,研究了该药剂对不同Cr6+浓度原水的还原螯合沉淀效果以及投药量、pH值对处理效果的影响。实验表明WY5具有较强的还原性,对Cr6+具有还原螯合作用,可以用简单的投药混凝的方法对含铬废水进行有效的处理,省去了采用常规深度处理含铬废水所需增加的设备和费用,具有较好的经济性和实用性。
The heavy metal chelating agent WY5 was prepared and used in the treatment of wastewater containing Cr (Ⅵ). The treatment effect to different concentration of Cr (Ⅵ) and the infulence of dosage ,pH value were study. WY5 has reducibility which can be used to treat wastewater containing Cr (Ⅵ) with good economical efficiency and practicability.
