- 摘要:
- 磷資源不可替代又不能再生�，F(xiàn)代工業(yè)攫取磷礦大多用于磷肥生產(chǎn)，通過(guò)作物收獲的糧食、蔬菜以及飼養(yǎng)畜禽肉類進(jìn)入人體，而隨食物進(jìn)入人體的大多數(shù)磷（90%）會(huì)隨排泄物進(jìn)入污水（無(wú)糞尿返田情況）。盡管最終進(jìn)入污水中的磷占開(kāi)采磷礦的比例很�。�<5%），但這是人類除動(dòng)物糞便與作物秸稈外唯一可能實(shí)現(xiàn)磷人工循環(huán)的位點(diǎn)，相對(duì)于轉(zhuǎn)移進(jìn)作物中的磷來(lái)說(shuō)該比例超過(guò)1/4。因此，在廢棄糞尿返田之原生態(tài)習(xí)慣的情況下，從污水處理過(guò)程中回收磷則顯得非常重要。目前從污水處理過(guò)程中回收磷存在許多方式與產(chǎn)品，而與污泥焚燒灰分相關(guān)的磷回收程度最高，可達(dá)90%。為此，首先基于全球磷資源危機(jī)與我國(guó)磷流向及其估算,揭示磷回收的必要性和急迫性。然后，對(duì)與污泥焚燒相關(guān)的灰分磷回收技術(shù)以及潛在應(yīng)用進(jìn)行總結(jié)和分析。最后，根據(jù)肥效實(shí)驗(yàn)與成本估算，認(rèn)定灰分再生磷肥比傳統(tǒng)礦石磷肥具有潛在市場(chǎng)前景，特別是它的可持續(xù)意義。
- Abstract:
- Phosphorus resources are irreplaceable and non-renewable either. Modern industry grabs phosphorus ores mainly for synthesizing phosphate fertilizers, and most of phosphorus (90%) entering human bodies via the food chains (crops, vegetables and meats) is finally transported into wastewater (without excreta returning to farmlands) discharged by human beings. Although phosphorus entering wastewater only accounts for a small proportion of phosphate ores (<5%) compared to exploited P-ores, this is the only site possibly recovering phosphorus besides animal manure and straws, which takes a share of >25% of phosphorus transported into crops. Under the circumstance of giving up excreta returning to farmlands, thus, recovering phosphorus from wastewater is very important. There are many approaches to recovering phosphorus and its products from wastewater nowadays. Phosphorus recovery relating to the bottom ashes of excess sludge incineration could reach up to the highest extent, up to 90%. Based on the global phosphorus crisis and its flowing patterns and evaluations in China, the article first revealed the importance and urgency of phosphorus recovery, followed by summarizing and analyzing the associated techniques and potential applications of phosphorus recovery from the bottom ashes. According to the fertilizer values and estimated prices, recovered phosphorus fertilizers from the bottom ashes could be finally believed to have a better market prospect than synthesized phosphate fertilizers, in particular which is sustainable.
