由此封閉工藝產(chǎn)生的廢水中的鎳含量〇.，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(yán)格執(zhí)行中華人民國家標(biāo)準(zhǔn)《電鍍污染物排放標(biāo)準(zhǔn)》(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。為了滿足環(huán)保標(biāo)準(zhǔn)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(bǔ)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(dá)到國家一級排放標(biāo)準(zhǔn)，會導(dǎo)致環(huán)境污染。造成鎳離子超標(biāo)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。封孔劑哪家好，詳情可以訪問百事德，歡迎您的光臨！江西鋁材封孔劑研發(fā)</p><p
