通过72 h的连续批量实验,分析高盐度生活污水在下水道环境中的主要微生物反应以及这些微生物反应对水质的影响。实验共进行两组,每组均在3种不同条件的反应器中进行,各反应器中均进行连续72h小时的取样和监测,确定摄氧率(OUR)、硝态氮(NOX)、氨氮(NH3)和溶解态有机碳(DOC)随时间的浓度变化。通过对实验数据的分析,结果表明高、低盐度生活污水在下水道环境中的影响污染物降解的主要微生物反应都是异养微生物的好氧增殖以及有机颗粒物的水解。但与低盐度污水不同的是,高盐度污水中的①硝化反应作用较为明显;②反硝化速率较快,而且由于硝化作用明显,可提供足够的硝氮,因此反硝化反应也不可忽略。根据此分析结果,以活性污泥3号模型(ASM3)为基础,综合考虑复氧、水力和环境温度影响,建立了下水道污水水质模型。经验证,模型可较好地模拟溶解氧、溶解性有机碳、氨氮和硝氮等物质的下水道中的浓度变化。

Nitrate is a crucial environmental pollutant,and its risk on ecosystem keeps *** conversion of nitrate to ammonia can simultaneously achieve the commercialization of environmental hazards and recovery of valuable ammonia,which is green and sustainable for the ***,due to the thermodynamic and kinetic energy barriers,photocatalytic nitrate reduction usually involves a higher selectivity of the formation of nitrogen that largely limits the ammonia synthesis *** this work,we reported a green and facile synthesis of novel metallic ruthenium particle modified graphitic carbon nitride *** with bulk graphitic carbon nitride,the optimal sample had 2.93-fold photocatalytic nitrate reduction to ammonia activity(2.627 mg/h/gcat),and the NH3 selectivity increased from 50.77%to 77.9%.According to the experimental and calculated results,the enhanced photocatalytic performance is attributed to the stronger light absorption,nitrate adsorption,and lower energy barrier for the generation of *** work may provide a facile way to prepare metal modified photocatalysts to achieve highly efficient nitrate reduction to ammonia.
