压力变化对活性污泥脱氮除磷效能的影响OA
High pressure aeration enhancing nitrogen and phosphorus removal efficiency of activated sludge system for treating domestic wastewater
曝气压力对活性污泥工艺的运行效能具有较大影响,通过改变曝气压力,考察了活性污泥系统中硝化反硝化、生物除磷等过程的性能变化,论述了曝气压力变化对活性污泥脱氮除磷的强化效果.试验结果表明,恒定高压力曝气和高压变压力曝气均可强化活性污泥对水中污染物的高效快速降解效能.恒定曝气压力下,在0.5~0.7 MPa左右时,污染物的去除效果最优,COD在3 h内降解至100 mg/L以下,去除率大于80%,出水氨氮在15 mg/L以下,去除率在60%以上,出水T…查看全部>>
