SBBR反应器SND脱氮的影响因素分析及响应曲面优化OA北大核心CSCDCSTPCD
Analysis on influencing factors of nitrogen removal via SND and optimization by RSM in SBBR
采用活性炭涂层改性悬浮填料，在连续曝气的条件下，考察了SBBR 反应器脱氮性能。结果表明，SBBR反应器表现出良好的同步硝化反硝化（SND）脱氮性能，对NH3-N 和TN 的去除率分别为80．7％和63．1％。典型周期内反应器同步硝化反硝化率可达82．7％。单因素试验发现，脱氮率随着曝气时间狋的增加而增加，随着溶解氧质量浓度ρDO和填料投加量δ增大而先增大后减小。同时，以溶解氧质量浓度、填料投加量和曝气时间为考察因素，脱氮率为评价指标，采用响应曲…查看全部>>
Nitrogen removal performance of SBBR reactor was investigated under the condition of continuous aeration with suspended packing by activated carbon coating modification.The results indicate that SBBR presents a good simultaneous nitrification and denitrification (SND )performance with the removal rates of NH3-N and TN at 80.7% and 63.1% respectively.During a typical cycle,SND rate can reach 72 .8%.Single factor experiments show that nitrogen removal rate inc…查看全部>>
