摘要:地球磷危機(jī)時(shí)代已經(jīng)來(lái)臨，唯有發(fā)掘“第二磷礦”才能有效遏制磷的匱乏速度。剩余污泥焚燒灰分是污水的磷匯，是實(shí)施磷回收的最佳位點(diǎn)。因灰分中重金屬含量較高，實(shí)施磷回收需要將其分離并加以利用。否則，回收磷難以與礦物磷形成競(jìng)爭(zhēng)。比較各種灰分磷回收方法發(fā)現(xiàn)，熱化學(xué)法中的Ash Dec工藝可利用金屬氯化物實(shí)現(xiàn)重金屬揮發(fā)分離，且可在尾氣凈化系統(tǒng)中實(shí)現(xiàn)重金屬回收，從而同步獲得具有高生物利用度的富磷相。為此，首先介紹Ash Dec工藝原理；繼而討論重金屬揮發(fā)限制性因素、列舉歐洲Ash Dec工藝案例以及目前法規(guī)與政策、闡述焚燒灰分作為磷肥生產(chǎn)原料的潛力；最后，探討Ash Dec從尾氣凈化系統(tǒng)中回收重金屬的可行性與研究現(xiàn)狀。
Abstract:The era of phosphorus crisis has appeared on the earth, and thus exploiting “the second phosphate mine” could effectively inhibit the rate of phosphorus scarcity. The incinerated ash of excess sludge is the phosphorus sink of wastewater and is also the best site for phosphorus recovery. Due to the high content of heavy metals in the ash, separation of heavy metals should be performed from the ash prior to phosphorus recovery. Otherwise, the recovered phosphorus is difficult to compete with mined phosphate. After comparing various phosphorus recovery methods from the ash, the Ash Dec process (thermochemical method) is defined as an effective one, as it can apply metal chlorides to achieve heavy metal volatilization and separation. Moreover, heavy metal recovery could be realized in the exhaust gas purification system. A phosphorus?rich phase with high bioavailability then could be obtained. In this work, discussion on Ash Dec process were performed as following: ① The principles of the Ash Dec process are first introduced. ② Factors limiting heavy metal volatilization is then discussed. ③ Engineering cases applied in Europe is listed. ④ Current directives/laws on recovered phosphorus applications is mentioned. ⑤ The potential of the ash used as a raw material for phosphate fertilizer production is elucidated. ⑥ The state?of?art research for recovering heavy metals from the exhaust gas purification system is stated.
