Abstract

Compared with the effect of total phosphorus removal by modified peat and ammonium nitrogen removal by modified zeolite respectively, ammonium nitrogen and total phosphorus removal by modified peat associated with modified zeolite from micro-polluted scenic-water were studied in this paper. The surface structures of natural material, modified material and the modified material after adsorption saturated in combined effect were analyzed by SEM. It was found that in combined effect experiment, the ability of total phosphorus 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 total phosphorus were simultaneous removed from micro-polluted scenic-water by the combined effect of modified peat and modified zeolite, and the effluent quality meets the reuse of urban recycling water-water quality standard for scenic water consumption (GB/T 18921-2002, China).
