摘要：城市污水處理廠產生的污泥組分復雜，重金屬和有機物含量高，處理難度大，污泥填埋坑對周圍環境存在持續污染的風險。結合工程實例，闡述污泥填埋坑綜合治理技術方案，為類似工(gong)程提供參考。

隨著我(wo)國(guo)(guo)城市化(hua)(hua)不斷深入(ru)和(he)發展，城市污(wu)(wu)水(shui)處理廠產(chan)生的(de)污(wu)(wu)泥(ni)(ni)量越來(lai)越大，目前國(guo)(guo)內對污(wu)(wu)水(shui)廠污(wu)(wu)泥(ni)(ni)的(de)處理方式(shi)主要(yao)有填埋、焚燒、協同處置、資源化(hua)(hua)利用等。由于(yu)污(wu)(wu)泥(ni)(ni)填埋成本低，大多(duo)(duo)數污(wu)(wu)水(shui)處理廠采取(qu)了“部(bu)分脫(tuo)水(shui)后填埋”的(de)方式(shi)處理污(wu)(wu)泥(ni)(ni)，全國(guo)(guo)各地(di)存在數量眾多(duo)(duo)的(de)污(wu)(wu)泥(ni)(ni)填埋坑。污(wu)(wu)泥(ni)(ni)自身具(ju)有含(han)水(shui)率高(gao)、有機污(wu)(wu)染物(wu)(wu)濃度高(gao)、重金屬含(han)量高(gao)等物(wu)(wu)理化(hua)(hua)學特性，如(ru)何科學地(di)治理污(wu)(wu)泥(ni)(ni)填埋坑，一直是環境修復行業的(de)難題。

1工程概況

某城市污(wu)(wu)水(shui)處(chu)理廠(chang)的污(wu)(wu)泥(ni)填埋坑面積約16萬平方米(mi)，原為天(tian)然坑塘，底部(bu)(bu)及四周未做任何防滲處(chu)理，污(wu)(wu)泥(ni)最大深度(du)16.5m，平均深度(du)11m，淤泥(ni)總(zong)量約163萬立方米(mi)，污(wu)(wu)泥(ni)來源為污(wu)(wu)水(shui)處(chu)理廠(chang)污(wu)(wu)泥(ni)和印染(ran)工業污(wu)(wu)泥(ni)。坑內污(wu)(wu)泥(ni)多為流塑狀(zhuang)，含(han)水(shui)率分(fen)布在79.4%~90.7%之間，坑內垂直(zhi)方向上各(ge)層污(wu)(wu)泥(ni)含(han)水(shui)率差(cha)別不大。污(wu)(wu)泥(ni)夾雜(za)部(bu)(bu)分(fen)建筑垃圾，有機質(zhi)含(han)量較(jiao)高(gao)，力學性能極差(cha)，大型機械無法直(zhi)接進場施(shi)工。經調查，污(wu)(wu)泥(ni)超標污(wu)(wu)染(ran)物為鉻、鋅、鈷、銻、釩、六價鉻、砷、氯仿、苯(ben)、氟化物、六氯苯(ben)、總(zong)石油烴（C10-C40）等。
