</p><p>酸堿度對聚丙烯酰胺的使用有很大影響。不同的PH值對選用的聚丙烯酰胺型號有不同的影響，所以在使用聚丙烯酰胺絮凝劑時，根據實際情況調整PH值，選擇可以發揮使用效果更好的聚丙烯酰胺型號。</p><p style="text-align:center"></p><p>陰/陽/非離子聚丙烯酰胺的PH值與使用范圍：</p><p>陰離子聚丙烯酰胺的有效PH范圍為5-14，弱酸、中性、堿性效果好。適用于帶正電荷的廢水。如電鍍廠、鋼鐵廠、電池廠、洗煤廠、冶金廢水、洗沙廠等。</p><p>陽離子聚丙烯酰胺的有效PH范圍為7-14。中性和堿性水處理效果好，適用于帶負電荷的廢水。如皮革廠、造紙廠、市政污水處理廠等。</p><p>非離子聚丙烯酰胺的有效PH范圍為2-8，中性和酸性水處理效果好，適用于復雜帶電的廢水。</p><p>那么聚丙烯酰胺的合適PH值是多少呢？</p><p>自來水溶解pH值，使稀釋的聚丙烯酰胺溶液恰到好處。陰離子聚丙烯酰胺適用于堿性和中性環境，對固體顆粒表面帶正電荷的體系有很好的絮凝效果。陰離子聚丙烯酰胺應用廣泛。目前大部分都是弱陰離子，水解度在26%左右。非離子絮凝劑適用于固體顆粒表面凈電荷低的體系，一般可用于酸性或近中性水質。</p><p>
