陽離子聚丙烯酰胺污泥脫水劑

在工業污(wu)(wu)水(shui)處(chu)理中(zhong)的后(hou)一(yi)(yi)步,往往是污(wu)(wu)泥(ni)脫水(shui)工藝,常選用(yong)(yong)陽(yang)(yang)離(li)子(zi)(zi)丙(bing)(bing)烯(xi)(xi)酰(xian)胺作(zuo)(zuo)為污(wu)(wu)泥(ni)脫水(shui)劑進行(xing)污(wu)(wu)泥(ni)脫水(shui),根(gen)據污(wu)(wu)泥(ni)的不(bu)同(tong)(tong)性質污(wu)(wu)泥(ni)來選擇不(bu)同(tong)(tong)離(li)子(zi)(zi)度(du)的陽(yang)(yang)離(li)子(zi)(zi)聚丙(bing)(bing)烯(xi)(xi)酰(xian)胺進行(xing)脫水(shui)處(chu)理。其作(zuo)(zuo)的原理是利用(yong)(yong)陽(yang)(yang)離(li)子(zi)(zi)聚丙(bing)(bing)烯(xi)(xi)酰(xian)胺分子(zi)(zi)鏈(lian)條上附(fu)(fu)帶的陽(yang)(yang)電荷(he)對污(wu)(wu)泥(ni)膠(jiao)粒(li)中(zhong)的負電荷(he)進行(xing)中(zhong)和(he),加(jia)快污(wu)(wu)泥(ni)絮凝,同(tong)(tong)時又(you)利用(yong)(yong)了(le)長分子(zi)(zi)鏈(lian)條將(jiang)污(wu)(wu)泥(ni)顆粒(li)纏繞在一(yi)(yi)起, 主要(yao)應用(yong)(yong)到(dao)陽(yang)(yang)離(li)子(zi)(zi)聚丙(bing)(bing)烯(xi)(xi)酰(xian)胺的壓縮雙電層(ceng)作(zuo)(zuo)用(yong)(yong)和(he)吸附(fu)(fu)架橋作(zuo)(zuo)用(yong)(yong)。聚丙(bing)(bing)烯(xi)(xi)酰(xian).胺PAM作(zuo)(zuo)為污(wu)(wu)泥(ni)脫水(shui)劑可分為自(zi)然干化脫水(shui)和(he)機(ji)械脫水(shui)。兩(liang)種污(wu)(wu)泥(ni)脫水(shui)的方式(shi)各有側重,但都需(xu)要(yao)用(yong)(yong)到(dao)PAM。

自(zi)然干化脫水指(zhi)的(de)(de)是(shi)將污(wu)泥放置在干化廣場(chang)通過(guo)蒸發、清液溢流和滲透(tou)的(de)(de)方(fang)(fang)式實現脫水,這種方(fang)(fang)法容易產生(sheng)(sheng)惡臭(chou),滋生(sheng)(sheng)疫病。機械脫水是(shi)我國目前污(wu)泥脫水的(de)(de)主要方(fang)(fang)式,主要是(shi)采(cai)(cai)用了(le)壓濾機等設(she)備對污(wu)泥進行脫水處(chu)理,期間(jian)采(cai)(cai)用聚(ju)(ju)丙(bing)烯酰(xian)胺(an)水處(chu)理藥劑加(jia)快脫水效率。PAM的(de)(de)型(xing)號(hao)有很多, 哪些適合用來(lai)污(wu)泥脫水用呢?以下(xia)是(shi)關于污(wu)泥脫水用聚(ju)(ju)丙(bing)烯酰(xian)胺(an)的(de)(de)選型(xing)的(de)(de)簡(jian)單介紹(shao)。

陽(yang)離(li)(li)子(zi)(zi)(zi)聚丙(bing)烯酰(xian)(xian)胺(an)(an)污泥脫水劑因離(li)(li)子(zi)(zi)(zi)度(du)(du)的高低,可分為弱陽(yang)離(li)(li)子(zi)(zi)(zi)、中(zhong)陽(yang)離(li)(li)子(zi)(zi)(zi)和強陽(yang)離(li)(li)子(zi)(zi)(zi)聚丙(bing)烯酰(xian)(xian)胺(an)(an)這(zhe)三種(zhong)(zhong)類型,離(li)(li)子(zi)(zi)(zi)度(du)(du)越(yue)高它的陽(yang)電荷(he)離(li)(li)子(zi)(zi)(zi)更多, 實現了(le)污泥脫穩的效(xiao)果更好(hao),但是離(li)(li)子(zi)(zi)(zi)度(du)(du)過高的陽(yang)離(li)(li)子(zi)(zi)(zi)聚丙(bing)烯酰(xian)(xian)胺(an)(an)分子(zi)(zi)(zi)重(zhong)一(yi)(yi)般(ban)不(bu)會太高，所以它其吸附架橋作用大打折扣。新鄉京華凈水材料建議在客戶需要使用陽(yang)離(li)(li)子(zi)(zi)(zi)聚丙(bing)烯酰(xian)(xian)胺(an)(an)進行(xing)(xing)污泥脫水處理(li)(li)時,好(hao)能先進行(xing)(xing)初步小試,再來(lai)確定需要使用哪(na)種(zhong)(zhong)離(li)(li)子(zi)(zi)(zi)度(du)(du)的陽(yang)離(li)(li)子(zi)(zi)(zi)聚丙(bing)烯酰(xian)(xian)胺(an)(an), 一(yi)(yi)方面(mian)能夠(gou)降低使用成本(ben),另一(yi)(yi)方面(mian)能夠(gou)提高污泥處理(li)(li)效(xiao)率。
