PAM与CaCl_2联用治理煤泥水

COMBINED USE OF PAM AND CaCl_2 IN THE TREATMENT OF COAL DRESSING WASTEWATER

通过对煤泥水ζ电位的测定,推断出煤泥水的胶粒结构。经对各种降低ζ电位的混凝剂的测试,得出钙盐是最理想的混凝剂,并确定了PAM与CaCl_2联用治理煤泥水的新方法。

Based on the test of the ζ- electromotive force of the coal dressing wastewater, the structure of the colloidal particles of the wastewater can be inferred. Calciferous salt is the ideal coagulant by testing some kinds of coagulant which can decrease the ζ- electromotive force, The experiment also shows that a new method is set up which deals with the coal dressing wastewater by using PAM and CaCl2 together.
