Abstract:: [Objective] To clarify the removal efficiency of nitrogen and phosphorus from domestic sewage by different substrates and to identify the suitable substrates and their dosage for rural domestic sewage treatment. [Methods] Taking zeolite and ceramsite as the research objects, their adsorption characteristics of a single substrate or substrate combinations on total phosphorus(TP) and ammonium nitrogen(NH4+-N) removal from simulated rural domestic sewage were investigated through indoor incubation, adsorption kinetic models, and isothermal adsorption models. [Results](1) Increasing the substrate dosage could improve the removal rate of nitrogen and phosphorus, and 16 g/L was the most suitable substrate dosage.(2) The adsorption capacities of zeolite and ceramsite for NH4+-N were 10.53 mg/g and 3.16 mg/g, respectively, while those for TP were 1.20 mg/g and 7.28 mg/g, respectively. The adsorption of NH4+-N and TP by zeolite and ceramsite mainly followed monolayer adsorption behaviour with chemisorption as the dominant mechanism.(3) The 1∶1 mixture of zeolite and ceramsite(FT11) demonstrated better adsorption performance for NH4+-N and TP and was identified as the optimal substrate combination. [Conclusion] In general, the adsorption processes of NH4+-N and TP by zeolite and ceramsite are more consistent with the Langmuir model. The results provide scientific support for the purification of rural domestic sewage and the construction of efficient ecological floating beds in the study area.
