摘要:
多段多级厌氧缺氧好氧工艺(MAAO)在实际工程中具有良好的运行效果,但在低碳氮比条件下如何优化运行策略尚不十分明确。本研究在低碳氮比条件下(C/N<6),分析了在5组不同的进水流量和污泥分流量条件下污染物的去除效率。结果表明:水力停留时间与同步硝化反硝化的贡献率是影响总氮去除率的关键因素,可通过加大前端进水比实现较长的水力停留时间;总磷的去除率主要依赖于第二、三、四级的厌氧池的释磷效率,该效率取决于厌氧池的水力停留时间。综合考虑系统的脱氮除磷效能,确定进水流量分配比为35%,30%,20%,15%,污泥分流比为10%,19%,29%的工况为最优工况。
Abstract:
Multilevel anaerobic/anoxic/oxic activated sludge process has been put into use with a favorable effect.However,it is not clear how to optimal operation strategy. Under 5 different influent qualities and sludge distribution qualities without changing other operating conditions, pollutant removal efficiency about low C/N ratio wastewater (C/N<6) were studied. The result shows that hydraulic retention time and simultaneous nitrification and denitrification abilities was critical factor of total nitrogen removal. The main removal of total phosphorus remove was achieved by the 2nd and 3rd and 4th level, the main limited factor of total phosphorus was the hydraulic retention time. After comprehensive consideration of the efficiency of nitrogen and phosphorus removal in the system and the subsequent optimization space, the best operating case was confirmed as the influent quality distribution ratio was 35%: 30%: 20%: 15%, and the sludge distribution ratio was 10%: 19%: 29%
