根據國家(jia)的相關規定，確認(ren)一(yi)種固(gu)體(ti)廢(fei)物是否為(wei)危險(xian)廢(fei)物有以下(xia)幾(ji)種途徑︰第一(yi)、列(lie)入《國家(jia)危險(xian)廢(fei)物名錄》的固(gu)體(ti)廢(fei)物是危險(xian)廢(fei)物。

第二、根據《危(wei)險(xian)(xian)(xian)廢物鑒別標準》通則規定，具有毒性(xing)(包括浸出毒性(xing)、急(ji)性(xing)毒性(xing)及其他毒性(xing))和感染性(xing)等(deng)一種(zhong)或一種(zhong)以(yi)上危(wei)險(xian)(xian)(xian)特性(xing)的危(wei)險(xian)(xian)(xian)廢物處理后(hou)的廢物仍屬于(yu)危(wei)險(xian)(xian)(xian)廢物，國家(jia)有關法規、標準另有規定的除外。

例如:江蘇淮河(he)化(hua)工有限公司廠(chang)內廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)主(zhu)要有單(dan)(dan)硝(xiao)基(ji)(ji)甲苯(ben)(ben)和鄰對甲苯(ben)(ben)胺生(sheng)產(chan)(chan)(chan)過程產(chan)(chan)(chan)生(sheng)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)、設(she)備(bei)及地面(mian)沖洗水(shui)(shui)(shui)、廢(fei)(fei)(fei)(fei)(fei)酸濃縮(suo)裝(zhuang)置真空(kong)泵排(pai)水(shui)(shui)(shui)、廢(fei)(fei)(fei)(fei)(fei)氣處(chu)理水(shui)(shui)(shui)、初期雨水(shui)(shui)(shui)和生(sheng)活(huo)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)等，單(dan)(dan)硝(xiao)基(ji)(ji)甲苯(ben)(ben)生(sheng)產(chan)(chan)(chan)過程產(chan)(chan)(chan)生(sheng)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)經酸析預(yu)處(chu)理+Fenton處(chu)理后與其他廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)混合(he)進行生(sheng)化(hua)處(chu)理。該(gai)公司委托(tuo)鑒定的(de)固體(ti)廢(fei)(fei)(fei)(fei)(fei)物為單(dan)(dan)硝(xiao)基(ji)(ji)甲苯(ben)(ben)生(sheng)產(chan)(chan)(chan)過程產(chan)(chan)(chan)生(sheng)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)物化(hua)污泥(ni)與混合(he)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)生(sheng)化(hua)污泥(ni)一并壓濾產(chan)(chan)(chan)生(sheng)的(de)污泥(ni)(以下簡稱委托(tuo)鑒定的(de)污泥(ni))。鑒定中心對委托(tuo)鑒定的(de)污泥(ni)危險(xian)特性進行了鑒定，形成如下意(yi)見︰

1.根據《江蘇淮河化(hua)(hua)工(gong)有限(xian)公(gong)司廢(fei)(fei)(fei)(fei)(fei)(fei)水(shui)(shui)處(chu)理(li)(li)(li)污(wu)泥(ni)(ni)危(wei)險(xian)廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)鑒(jian)別報(bao)告》專家評(ping)審意(yi)見，該公(gong)司單(dan)(dan)硝(xiao)(xiao)基甲苯(ben)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)(chan)過(guo)(guo)程中產(chan)(chan)(chan)生(sheng)(sheng)(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)(fei)水(shui)(shui)，屬(shu)于(yu)(yu)《國家危(wei)險(xian)廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)名錄》(HWO6“有機(ji)溶劑廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)”261-001-06“苯(ben)胺生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)(chan)過(guo)(guo)程中產(chan)(chan)(chan)生(sheng)(sheng)(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)(fei)液。按照《關于(yu)(yu)化(hua)(hua)工(gong)等(deng)行業生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)(chan)廢(fei)(fei)(fei)(fei)(fei)(fei)水(shui)(shui)物(wu)(wu)(wu)化(hua)(hua)處(chu)理(li)(li)(li)污(wu)泥(ni)(ni)屬(shu)性判定的(de)復函(han)》(環辦函(han)〔號)要求，化(hua)(hua)工(gong)等(deng)行業屬(shu)于(yu)(yu)危(wei)險(xian)廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)的(de)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)(chan)廢(fei)(fei)(fei)(fei)(fei)(fei)液不作為(wei)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)(chan)廢(fei)(fei)(fei)(fei)(fei)(fei)水(shui)(shui)進行管理(li)(li)(li)，其物(wu)(wu)(wu)化(hua)(hua)處(chu)理(li)(li)(li)過(guo)(guo)程中產(chan)(chan)(chan)生(sheng)(sheng)(sheng)(sheng)的(de)污(wu)泥(ni)(ni)適用(yong)《國家危(wei)險(xian)廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)名錄》中類其他廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)中“危(wei)險(xian)廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)物(wu)(wu)(wu)化(hua)(hua)處(chu)理(li)(li)(li)過(guo)(guo)程中產(chan)(chan)(chan)生(sheng)(sheng)(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)(fei)水(shui)(shui)處(chu)理(li)(li)(li)污(wu)泥(ni)(ni)和殘渣”。因此，該公(gong)司單(dan)(dan)硝(xiao)(xiao)基甲苯(ben)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)(chan)過(guo)(guo)程產(chan)(chan)(chan)生(sheng)(sheng)(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)(fei)水(shui)(shui)物(wu)(wu)(wu)化(hua)(hua)污(wu)泥(ni)(ni)屬(shu)于(yu)(yu)危(wei)險(xian)廢(fei)(fei)(fei)(fei)(fei)(fei)物(wu)(wu)(wu)(802-006-49 )。

⒉根據《危(wei)(wei)險(xian)廢(fei)(fei)(fei)物(wu)(wu)(wu)(wu)(wu)鑒(jian)(jian)(jian)別標準GB5085.7-2007 )，具有毒性的(de)危(wei)(wei)險(xian)廢(fei)(fei)(fei)物(wu)(wu)(wu)(wu)(wu)與其他固體廢(fei)(fei)(fei)物(wu)(wu)(wu)(wu)(wu)混(hun)合(he)，混(hun)合(he)后的(de)廢(fei)(fei)(fei)物(wu)(wu)(wu)(wu)(wu)屬于危(wei)(wei)險(xian)廢(fei)(fei)(fei)物(wu)(wu)(wu)(wu)(wu)。因此，鑒(jian)(jian)(jian)定中心判定該公(gong)司委(wei)(wei)托(tuo)鑒(jian)(jian)(jian)定的(de)污泥(ni)(單(dan)硝基甲苯生產過程產生廢(fei)(fei)(fei)水物(wu)(wu)(wu)(wu)(wu)化(hua)污泥(ni)和混(hun)合(he)廢(fei)(fei)(fei)水生化(hua)污泥(ni)的(de)混(hun)合(he)物(wu)(wu)(wu)(wu)(wu))屬于危(wei)(wei)險(xian)廢(fei)(fei)(fei)物(wu)(wu)(wu)(wu)(wu)(802-006-49 )。該公(gong)司須嚴(yan)格按照危(wei)(wei)險(xian)廢(fei)(fei)(fei)物(wu)(wu)(wu)(wu)(wu)管理要求開(kai)展(zhan)委(wei)(wei)托(tuo)鑒(jian)(jian)(jian)定的(de)污泥(ni)處置工作。

按照這個規則，只要涉及到危(wei)廢處置，并且(qie)發生了混合(he)的情(qing)況，相(xiang)關物質(zhi)都屬于危(wei)廢。

第三、對不明(ming)確是否具有(you)危(wei)險(xian)特性(xing)(xing)的固體廢物，應當按著(zhu)國家(jia)規定(ding)的鑒(jian)別標準和鑒(jian)別方(fang)法予以認定(ding)。經(jing)鑒(jian)別具有(you)危(wei)險(xian)特性(xing)(xing)的，屬于(yu)危(wei)險(xian)廢物，經(jing)鑒(jian)別不具有(you)危(wei)險(xian)特性(xing)(xing)的，不屬于(yu)危(wei)險(xian)廢物。
