由此封閉工藝產(chǎn)生的廢水中的鎳含量〇.，常州鋁材表面封孔劑表面活性劑，其它添加劑的含量。[0005]由于長時間接觸鎳，輕者會引起皮炎，重者可能有致的危險，因此我國加大了對鎳污染的控制力度，從2008年以來，對于國土開發(fā)密度較高、環(huán)境承載能力減弱地區(qū)，如珠三角地和長三角的部分地區(qū)嚴格執(zhí)行中華人民國家標準《電鍍污染物排放標準》(GB21900-2008)中的表3規(guī)定水污染物特別排放限值，其中總鎳的含量不超過，常州鋁材表面封孔劑表面活性劑，常州鋁材表面封孔劑表面活性劑。為了滿足環(huán)保標準的要求，大多數(shù)企業(yè)將這類含鎳廢水與其他廢水分開，單獨處理。[0006]目前，常用的處理含鎳廢水方法有化學(xué)沉淀法（即用堿調(diào)節(jié)含鎳廢水pH值，并加金屬補集劑等中和、混凝、絮凝、沉淀）、離子交換法、吸附法、電滲析法、蒸發(fā)濃縮法和反滲法等。其中離子交換法及吸附法對絡(luò)合態(tài)的大分子無法有效破除；電滲析法及反滲透對膜的要求很高，容易造成膜的破壞;蒸發(fā)濃縮法對設(shè)備要求高，需要用到熱源，處理能耗高。[0007]中國**CN。[0008]中國**CN2采用陰離子交換樹脂吸附鎳離子的陽極著色廢水處理方法。[0009]上述兩種方法處理后的廢水均無法持續(xù)穩(wěn)定地達到國家一級排放標準，會導(dǎo)致環(huán)境污染。造成鎳離子超標的原因在于封孔溶液中含有能與鎳離子形成穩(wěn)定絡(luò)合物的絡(luò)合劑。</p><div

在以氟鈦酸為封孔主要成分的無鎳封孔液新配方條件下，工藝參數(shù)有很大的變化：封孔溫度15-35℃封孔速度1-3um/min槽液PHF-濃度氟鈦酸自帶，不專門限制（7）H2TiF6(50%)濃度比較式(6)與(7)，氟鈦酸的封孔能力比氟化鎳強，封孔溫度下限由25℃拓寬至15℃，封孔速度1um/min提高至3um/min，槽液，但范圍拓寬。由于含大量螯合劑，新配方對水質(zhì)要求不高，開槽用自來水即可，所含Ca2+、Mg2+可被螯合劑完全屏蔽。氟化鎳封孔的F-濃度為，分子結(jié)構(gòu)中F-不夠，需要額外補氟；氟鈦酸分子結(jié)構(gòu)中，氟含量過高，為此，配方中專門設(shè)置緩蝕劑，降低氟的腐蝕能力，故F-按式（2），自動水解平衡，無需檢測和控制。氟化鎳封孔的Ni2+濃度為，氟鈦酸槽液中鈦不是以Ti4+存在，而是以Ti(OH)3F32-+Ti(OH)2F42-+Ti(OH)F52-存在，故選用H2TiF6(50%)濃度。式（1）-（5）顯示封孔動力學(xué)的全過程。式（1）表明氟鈦酸在槽液中電離成2H++TiF62-；式（2）表明氟鈦酸根在槽液中水解成Ti(OH)3F32-+Ti(OH)2F42-+Ti(OH)F52-，并釋放6H++6F-；式（4）表明F-在氧化膜微孔反應(yīng)，釋放出OH-，提高微孔中的pH值；式（3）表面在氧化膜微孔中，pH值的升高，Ti(OH)3F32-進一步水解，生成封孔物資Ti(OH)4，完成封孔。由此可見。</p><div
