摘要:

生物脱氮除磷工艺在城镇污水处理过程中发挥了重要作用,随着排放标准的提升,现有常用工艺出水无法满足排放标准的要求。分析了生物脱氮除磷的机理,比较了不同处理工艺,解析了城镇污水进水碳源不足、不同菌属微生物相互竞争、生物活性影响、污泥膨胀和生物泡沫等生物脱氮除磷工艺存在的问题,提出调整工艺运行条件、改造工艺结构、补充碳源、投加填料、添加化学除磷药剂和使用生物选择器等生物脱氮除磷调控措施。

Abstract:

The biological nitrogen and phosphorus removal process plays an important role in the municipal wastewater treatment. With the increase of emission standards, the process effluent cannot meet the emission requirements. The mechanism of biological nitrogen and phosphorus removal was analyzed, and the different treatment processes were compared. The problems of insufficient carbon source in municipal wastewater influent, competition among different microorganisms, biological activity impact, sludge expansion and biological foam in the biological nitrogen and phosphorus removal process were analyzed. The measures for biological nitrogen and phosphorus removal such as adjusting process operating conditions, reforming process structure, supplementing carbon source, adding filler, adding chemical dephosphorization agents and using bioselectors were proposed.

Key words: municipal wastewater, nitrogen and phosphorus removal, treatment process, control
