通过对煤泥水性质的测定，推断出煤泥水的胶粒结构为：｛［ＳｉＯ２］ｍ·ｎＳｉＯ２－３，２（ｎ－ｘ）Ｈ＋｝２ｘ－和｛［Ａｌ（ＯＨ）３］ｍ·ｎＡｌＯ－２，（ｎ－ｘ）Ｈ＋｝ｘ－．通过对各种降低ζ电位混凝剂的测试，得出电石渣是最理想的混凝剂．确定了ＰＡＭ与电石渣联用治理煤泥水的新方法．
Through the determination of the properties of slime water, we infer that the colloidal structure of slime water is: {[SiO2] m · nSiO2-3,2 (n-x) H +} 2x- and {[Al (OH) 3] m · nAlO -2, (n-x) H +} x-. Through a variety of tests to reduce ζ potential coagulant, carbide slag obtained is the best coagulant. The new method of treating slime water with PAM and carbide slag was determined.
