摘要
介绍了多种生物法脱氮除磷常规工艺及新工艺,通过分析认为工艺流程复杂、回流比大、耗能多、运营成本高;或是工艺耐冲击负荷能力低、脱氮除磷效果不稳定等,是限制多数生物脱氮除磷工艺广泛应用的主要原因。提出了研究开发生物膜法脱氮除磷工艺的新思路和发展方向。
Several conventional and new biological nutrient removal processes were introduced in this psper. Through analysing their main shortcomings,authors indicated that the reason which limited the application of these proceses is of two aspects： the first is too complxe structures,high recycling ratio, the second is low ability of shock loading resistance and unsteady nutrient removal, It was put forward that biofilm process for nutrient removal will be the hotspot which experts devote themself to.
