試驗中通過改變流速(通過離子交換柱) 、進水中重金屬離子( hg2 + )的濃度以及向原水中引入天然水體中常見的陽離子( ca2 + 、 mg2 + )和陰離子( cl 、 so42 )等方法,比較了弱堿性陰離子離子交換樹脂和陽離子交換樹脂對飲用水中微量重金屬離子( hg2 + )的去除效果。The results show that when the concentration of hmi ( hg2 + ) in influent water is every low, the effect of hmi removal by wbaer from dk is much better than cations exchange resins. with cations ( ca2 +, mg2 + ) at high concentration in raw water, wbaer has better selectivity to hmi in water, however the selectivity of cations exchange resins is worse. the anions in raw water such as cl - which is able to react with hmi can make cations exchange resins lose the capability of hmi removal, but it has no effect on wbaer ( d301g )
結果表明:當進水中重金屬離子( hg2 + )濃度較低時,弱堿性陰離子交換樹脂對飲用水中hg2 +的去除效果要明顯優于陽離子交換樹脂;當原水中含有相對較高濃度的陽離子( ca2 + 、 mg2 + )時,弱堿性陰離子交換樹脂對水中的重金屬離子具有很高的選擇去除性,而陽離子交換樹脂的選擇去除性卻很差;天然原水中能與重金屬離子( hg2 + )發生絡合反應的陰離子(如: cl ) ,可以使陽離子交換樹脂喪失了對水中微量重金屬離子( hg2 + )的去除作用,而對弱堿性陰離子交換樹脂( d301g型)去除水中微量hg2 +的影響卻很小。By means of static and dynamic experiments, lots of research on the effect of micro - quantity heavy metal ions ( hmi ) removal by weakly basic anion exchange resins ( wbaer ) from drinking water ( dk ) with alkali metals, alkaline - earth metals and anions at high concentration, has been done

第二章首先以xyz - 1型電化學抑制柱為例,分析了電化學抑制柱的抑制過程得出影響抑制容量的主要因素主要是抑制柱的電流效率和離子交換膜的極限電流密度,因此採用中等交換能力的離子交換樹脂作為抑制室的填料以提高電流效率,在通常情況下電流效率可達到90以上;在選用同種離子交換膜的前提下,可通過增加離子交換膜的有效面積達到提高極限電流的目的從而提高抑制柱的抑制容量,因此提出了多級抑制的概念並據此研製了共電極式高容量電化學抑制柱,該抑制柱最高可將流速為1 . 0ml / min ,濃度為200mmol / l電導率超過10000 s ? cm ~ ( - 1 )氫氧化鈉溶液抑制為電導率低至8 . 9 s ? cm ~ ( - 1 )的純水,並且具有穩定性高、分析結果準確等優點。In a word, wbaer can effectively remove micro - quantity hmi from dk with alkali metals, alkaline - earth metals and anions at high concentration. on the basis of lots of regeneration experiments of wbaer ( d301g ), the best regeneration manner ( regurgitation regeneration ), the optimal regeneration agents ( h2so4 and naoh ) and the optimum operating parameters of regeneration are obtained
