摘要/Abstract

摘要： 从源分离尿液中回收磷既能减少城市污水中近50%的磷负荷，又可以促进磷资源的可持续循环。本研究利用物理筛分（d≤100μm）后的天然黄土颗粒作为吸附材料来回收水解尿液中的磷酸盐，重点考察了其对磷酸盐的吸附性能及该过程的作用机制。另外，还建立了吸附动力学和等温线方程，并且讨论了初始pH和接触时间对吸附过程的影响。研究结果表明，黄土颗粒对水解尿液中磷酸盐具有较强的吸附能力，初始pH是影响其对磷酸盐吸附性能的主要因素，最大吸附容量发生在初始pH为10.0时，可达到5.28mg/g。黄土颗粒吸附水解尿液中磷酸盐的主要作用机制是≡M-OH官能团与磷酸根的配位交换反应、羟基磷酸钙沉淀反应及磷酸铵镁沉淀反应，并且水解尿液中高氨氮浓度对黄土颗粒吸附磷酸盐具有促进作用。另外，该吸附过程符合伪二级（R₂²=0.998）动力学方程且吸附规律符合Freundlich（R_F²=0.990）等温线方程。

Abstract: Source separation of human urine coupled with phosphorus (P) recovery could decrease 50% of P present in wastewater and promote a sustainable recyclability and management of P resource.In this study,Chinese loess particle (d ≤ 100μm) without physical or chemical modification was used as an adsorbent for adsorption and recovery of phosphate from hydrolysis urine.Batch experiments were conducted for investigating the adsorption capacity of loess particle and the mechanisms of adsorption processes.In addition,adsorption kinetics and isotherms,as well as the major influencing factors such as initial pH and contact time were investigated.The results revealed that loess particle was a cost-effective adsorbent for phosphate adsorption from hydrolysis urine under the optimal conditions.The initial pH of hydrolysis urine was the key factor for phosphate adsorption capacities of loess particle,and the maximum phosphate adsorption capacities was 5.28mg/g at an initial pH of 10.0.Differing with the electrostatic repulsion of phosphate adsorption from synthetic phosphate solution onto loess particle,the processes of phosphate adsorption from hydrolysis urine onto loess particle were mainly based on the action of inner-sphere ligand exchange between ≡M-OH groups and phosphate,calcium phosphate precipitation reaction and magnesium ammonium phosphate precipitation reaction.In addition,the presence of ammonium nitrogen in hydrolysis urine had an obvious positive effect on the adsorption of phosphate.Furthermore,the adsorption processes of phosphate onto loess particle was well described by pseudo-second-order kinetic model (R₂²=0.998) and Freundlich isotherm model (R_F²=0.990).

Key words: loess particle, adsorption, ligand exchange, precipitation, kinetics, isotherm
