实验研究改性的泥炭与沸石联合作用下同步对微污染水体的脱氮除磷效果,并与单独的改性泥炭除磷和改性沸石脱氮效果进行对比分析,以及通过SEM分析泥炭和沸石改性前后以及联合作用下两种改性材料饱和后的形态特点.实验结果表明,联合作用下改性泥炭吸附水溶液中的磷酸根能力提高,且会释放氨氮,改性沸石吸附水溶液中的氨氮能力下降,改性的泥炭与沸石可同步去除微污染水体的氨氮和磷,出水水质达到国家景观环境用水的再生水指标.

Compared with the effect of phosphate removal by modified peat and nitrogen removal by modified zeolite respectively, simultaneous removal of nitrogen and phosphate by modified peat and zeolite from micro-polluted water body were studied in this paper. The configuration characters of natural material, modified material and the modified material after saturated were analyzed by SEM. It was found that in combined experiment, the ability of phosphate removal in aqueous solution by modified peat was improved and the peat released ammonium nitrogen, the ability of ammonium nitrogen removal in aqueous solution by modified zeolite was decreased. Ammonium nitrogen and phosphate were simultaneous removed from micro-polluted water body by the combined effect of modified peat and zeolite, and the effluent quality meets the reuse of urban recycling water quality standard(GB/T 18921-2002, China).
