inherit;"> 在飲用水處理。我國很多自來水廠的水源自江河泥少及礦物質含量高，比較混濁，雖經過沉淀處理，但仍達不到要求，需要投加絮凝劑，那么聚丙烯酰胺污水預處理是選擇陰離子還是陽離子呢？下面內容了解更多！<br/> 聚丙烯酰胺的工業應用:聚丙烯酰胺(PAM)分子量高，水溶性好，分子量可調，并能引入各種離子基團獲得特定的性能。低分子量是分散材料的添加劑或穩定劑，而高分子量是一種重要的絮凝劑，它能使親水性和水不溶性凝膠化，并對許多基團的表面和溶解物質有良好的粘附性。由于上述性質，聚丙烯酰胺被廣泛應用于絮凝、增稠、減阻、仿膠、粘附、阻垢等領域。<br/> 飲用水處理。我國許多自來水廠的水來自泥漿少、礦物質含量高的河流，水質混濁。雖然已經沉淀，但仍不能滿足要求。需要添加絮凝劑來凈化水質。許多水廠使用無機絮凝劑，但用量大，導致污泥增加效果差。陰離子聚丙烯酰胺用作絮凝劑，用量是無機絮凝劑的五分之一，但效果卻是幾倍到幾十倍。特別是我公司生產的聚丙烯酰胺殘留單體已達到食品級(小于0.05%)，接近國外的高超水平。它無毒，更適合處理飲用水。在有機污染嚴重的河水中，與陰離子聚丙烯酰胺配合使用效果更好。<br/> 聚丙烯酰胺用于回收淀粉廠和酒精廠損失的淀粉和酒糟。目前，許多淀粉廠排放的廢水中淀粉含量很高，排放后影響環境，浪費資源。加入聚丙烯酰胺沉淀淀粉，沉淀物用壓濾機壓成餅用作飼料。大量的酒糟都是用這種方法加工的。黑龍江某酒精廠采用聚丙烯酰胺作為絮凝劑，回收了酒糟，取得了巨大的經濟效益。聚丙烯酰胺溶液粘度能判斷質量的好壞嗎？<br/> 一種新型的水處理劑聚丙烯酰胺，當在許多場合處理污水和水時，陰離子聚丙烯酰胺和陽離子聚丙烯酰胺的組合與單獨使用離子聚丙烯酰胺相比具有非常的協同作用。聚丙烯酰胺降低表面張力的能力遠遠大于陽離子或陰離子在相同條件下單獨存在的能力。<br/> 為了滿足降低表面張力的要求，必須同時使用陰離子和陽離子聚丙烯酰胺。如果使用不當，會產生白色沉淀，失去使用效果。然而，聚丙烯酰胺具有兩性離子的特性，能夠在不沉淀的情況下完成陰離子和陽離子的配位和協同作用，特別是對于水質復雜或水質變化頻繁的情況，使用聚丙烯酰胺作為絮凝劑更加方便。<br/></span></p> </li> </ul> <div class="f14">
