摘要
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．
Based on the test of the properties of the coal dressing wastewater,the structure of the colloidal particles of the wastewater can be inferred:{} m n SiO 2- 3,2( n-x) H +} 2 x - and {[Al(OH) 3] m·n AlO - 2, (n-x) H +} x- . Carbide ash is ideal coagulant by testing some kinds of coagulants capable of lowering the ζ electromotive force. A new method is set up for dealing with the coal dressing wastewater by using PAM and carbide ash together.
