  • 摘要: 利用X射线衍射和能谱分析技术，对富磷上清液铁接触除磷污泥进行了成分与性质分析。结果表明，污泥经陈化作用后其主要成分为FePO4、FeO(OH)和Ca3(PO4)2，各组分的相对质量百分比分别为27.01%、65.52%和7.47%。污泥的沉降性能良好，沉淀6～8 h后总铁浓度＜3 mg/L。分析了污泥资源化利用的方法，提出可将污泥直接用作农肥或土壤改良材料，也可通过高温灼烧、焦硫酸钾溶解、过滤等过程将其分离为铁矿（Fe2O3·nH2O）和磷矿（FePO4和 Ca3(PO4)2）后再利用。
    Abstract: The component and characters of sludge produced from phosphorus removal by iron-contactor process (PRICP) for anaerobic phosphateenriched supernatant (APES) were analyzed using X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS). The result shows that, after an ageing process of sludge from PRICP for APES, the main component are FePO4, FeO(OH) and Ca3(PO4)2, and the mass percentages are 27.01%, 65.52% and 7.47% respectively. The settling performance of sludge is good, the total iron is less than 3 mg/L after a hydraulic retention time of 6～8 h. Sludge resource reuse methods were analyzed. These methods include applying sludge to crop production as agricultural fertilizer or soil amendment. In addition, it can be separated into iron resources (Fe2O3·nH2O) and phosphate resources (FePO4 and Ca3(PO4)2) through high temperature incineration、disulfuric acid potassium dissolving and filtering.
