摘要

实现磷资源的高效回收和农业废弃物的资源化利用具有重要意义。采用氯化铁、硫酸铁、氯化钙对水稻秸秆生物炭（RSB）进行改性，得到3种改性稻秆生物炭（PRSB-Fe、PRSB-FS和PRSB-Ca），采用SEM、XPS、FTIR和BET对其进行表征，并通过批量实验探究其对模拟废水和化粪池粪污分离液中磷酸盐的吸附特性。模拟废水实验结果表明：伪二级动力学方程能更好地描述改性生物炭对磷的吸附过程（

0.99），吸附机制以化学吸附为主，吸附等温线均更符合Freundlich方程（20 ℃），表明多层吸附可能起主导作用。共存的Cl

基本不会影响3种改性生物炭对磷的吸附效果；对于初始磷浓度为（12.94±1.51） mg/g、pH值为7.4±0.2的化粪池粪污分离液，PRSB-Fe-5、PRSB-FS-5和PRSB-Ca-5对磷的吸附量分别是10.77、23.35、0.85 mg/g，其中PRSB-FS-5对磷的吸附效果最好，去除率高达97.31%，剩余磷浓度仅有0.37 mg/L，达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准。

Abstract

It is significant to realize the efficient recovery of phosphorus resource and resource utilization of agricultural wastes. Three kinds of modified rice straw biochar (PRSB-Fe

PRSB-FS and PRSB-Ca) were prepared by modifying rice straw biochar (RSB) with FeCl

(SO

)

and CaCl

respectively. SEM

XPS

FTIR and BET characterized the modified biochar. Its adsorption capacity for phosphate in simulated wastewater and feces and wastewater separation solution of septic tank was explored by batch experiments. The results of simulated wastewater test showed that the adsorption of phosphorous by three modified biochar was well fitted to the pseudo-second-order kinetic model (

0.99)

which indicating chemical adsorption was the major. The adsorption isotherms were more consistent with Freundlich equation at 20 ℃

indicating that multilayer adsorption was dominant. In addition

the coexistence of Cl

had little effect on the adsorption capacity of modified biochar. For the feces and wastewater separation solution of septic tank with initial phosphorus concentration of (12.94±1.51) mg/g

pH value of 7.4±0.2

the adsorption capacity of PRSB-Fe-5

PRSB-FS-5 and PRSB-Ca-5 for phosphorus was 10.77

23.35 and 0.85 mg/g

respectively. PRSB-FS-5 had the best adsorption of phosphorus

with the removal rate as high as 97.31%

and the residual phosphorus concentration was only 0.37 mg/L

reaching the first level A standard of

Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant

(GB 18918-2002).
