摘要:地球磷危机时代已经来临，唯有发掘“第二磷矿”才能有效遏制磷的匮乏速度。剩余汙泥焚烧灰分是污水的磷汇，是实施磷回收的最佳位点。因灰分中重金属含量较高，实施磷回收需要将其分离并加以利用。否则，回收磷难以与矿物磷形成竞争。比较各种灰分磷回收方法发现，热化学法中的Ash Dec工艺可利用金属氯化物实现重金属挥发分离，且可在尾气净化系统中实现重金属回收，从而同步获得具有高生物利用度的富磷相。为此，首先介绍Ash Dec工艺原理；继而讨论重金属挥发限制性因素、列举欧洲Ash Dec工艺案例以及目前法规与政策、阐述焚烧灰分作为磷肥生产原料的潜力；最后，探讨Ash Dec从尾气净化系统中回收重金属的可行性与研究现状。
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.
