針對不同的污染土壤，土壤修復設備技術(shu)的選擇要(yao)結合(he)技術(shu)的特(te)(te)點，并充分考慮修(xiu)復(fu)經(jing)費的數(shu)量、未來土(tu)地(di)的利(li)用方式、區域地(di)形和(he)氣候特(te)(te)點、污(wu)(wu)(wu)染(ran)物種類、污(wu)(wu)(wu)染(ran)程度(du)及(ji)修(xiu)復(fu)周期等一系列因素。對于重金屬污(wu)(wu)(wu)染(ran)土(tu)壤其修(xiu)復(fu)技術(shu)主要(yao)有(you)客(ke)/換(huan)土(tu)、土(tu)壤淋洗、穩定化、電動(dong)和(he)植物修(xiu)復(fu)等。

        大規模土壤重金屬污染修復工(gong)程使(shi)用的(de)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)核(he)心(xin)是成本控制，其次是環境(jing)友好與農(nong)民參與，最后是修(xiu)(xiu)復(fu)(fu)效(xiao)果的(de)持久(jiu)性(xing)(xing)。總結目前(qian)適(shi)合重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)污(wu)(wu)染土(tu)壤(rang)修(xiu)(xiu)復(fu)(fu)的(de)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)措施，在(zai)(zai)規模化(hua)(hua)(hua)(hua)的(de)農(nong)田土(tu)壤(rang)修(xiu)(xiu)復(fu)(fu)工(gong)程中(zhong)(zhong)適(shi)用的(de)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)主(zhu)要有(you)兩種，一是土(tu)壤(rang)重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)活性(xing)(xing)化(hua)(hua)(hua)(hua)學(xue)鈍化(hua)(hua)(hua)(hua)/穩定(ding)(ding)化(hua)(hua)(hua)(hua)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)；二是植(zhi)(zhi)物(wu)(wu)修(xiu)(xiu)復(fu)(fu)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)。化(hua)(hua)(hua)(hua)學(xue)鈍化(hua)(hua)(hua)(hua)/穩定(ding)(ding)化(hua)(hua)(hua)(hua)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)是指通(tong)過向土(tu)壤(rang)中(zhong)(zhong)添加改(gai)良材料使(shi)重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)向低(di)(di)溶解、固定(ding)(ding)態(tai)等(deng)低(di)(di)毒形態(tai)轉(zhuan)化(hua)(hua)(hua)(hua)，達到降低(di)(di)污(wu)(wu)染土(tu)壤(rang)重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)生(sheng)物(wu)(wu)有(you)效(xiao)性(xing)(xing)和(he)環境(jing)風險的(de)方法。常用的(de)鈍化(hua)(hua)(hua)(hua)材料分為有(you)機(農(nong)業廢棄物(wu)(wu)、有(you)機肥、生(sheng)物(wu)(wu)質炭等(deng))和(he)無機(如鈣、磷類(lei)(lei)礦物(wu)(wu)、含硅類(lei)(lei)粘土(tu)礦物(wu)(wu))兩大類(lei)(lei)型。該(gai)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)的(de)優點是原位固化(hua)(hua)(hua)(hua)(吸(xi)附或共沉(chen)(chen)淀)降低(di)(di)重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)的(de)有(you)效(xiao)性(xing)(xing)，成本較低(di)(di)，缺(que)點是重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)仍滯留在(zai)(zai)土(tu)壤(rang)中(zhong)(zhong)。植(zhi)(zhi)物(wu)(wu)修(xiu)(xiu)復(fu)(fu)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)是指利用植(zhi)(zhi)物(wu)(wu)及根(gen)際(ji)微生(sheng)物(wu)(wu)來去(qu)除、轉(zhuan)移、提取和(he)固定(ding)(ding)土(tu)壤(rang)、沉(chen)(chen)積(ji)物(wu)(wu)、地表水、地下(xia)水甚(shen)至大氣中(zhong)(zhong)的(de)重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)，用于重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)污(wu)(wu)染土(tu)壤(rang)修(xiu)(xiu)復(fu)(fu)的(de)理想植(zhi)(zhi)物(wu)(wu)需(xu)要滿足對重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)有(you)一定(ding)(ding)的(de)耐性(xing)(xing)或超(chao)積(ji)累能力、生(sheng)長(chang)迅速且具有(you)較大的(de)生(sheng)物(wu)(wu)量(liang)等(deng)條件。該(gai)技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)優點是實施簡便，投資較少(shao)，對環境(jing)擾動(dong)性(xing)(xing)小。缺(que)點是修(xiu)(xiu)復(fu)(fu)效(xiao)率低(di)(di)，同時因改(gai)變種植(zhi)(zhi)結構，農(nong)民不(bu)易接受。實際(ji)工(gong)程中(zhong)(zhong)，規模化(hua)(hua)(hua)(hua)的(de)耕(geng)地土(tu)壤(rang)重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)治理往往采(cai)用重(zhong)(zhong)(zhong)金(jin)屬(shu)(shu)(shu)(shu)活性(xing)(xing)化(hua)(hua)(hua)(hua)學(xue)鈍化(hua)(hua)(hua)(hua)/穩定(ding)(ding)化(hua)(hua)(hua)(hua)+植(zhi)(zhi)物(wu)(wu)(作(zuo)物(wu)(wu))+農(nong)藝調控相(xiang)結合的(de)組(zu)合式(綜合性(xing)(xing))技(ji)(ji)(ji)(ji)術(shu)(shu)(shu)(shu)(shu)。
