VFAs、TOC及COD作为生物除磷能力指标的探讨
Comparative study on COD,TOC,VFAs as biological phosphorus removal index
摘要
Abstract
Variation of phosphorus at the relationship of COD,TOC and fatty acids(VFAs) along with the phosphorus releasing period with real domestic wastewater were investigated.The experimental results showed that the variety of VFAs concentration would reflect the process of phosphorus releasing accurately.The proportion of organic substance used in phosphorus releasing was 13.33% of total COD in real domestic wastewater,and approximately 1.401 mg VFAs-COD were required to release 1mg of soluble phosphorus.The domestic wastewater composed by three parts,readily bio-degradable organic substance,refractory organic substance and reduction COD via the analysis of the COD,TOC and VFAs.The proportion of three parts was 13.33%,31.7% and 54.97%,respectively.The proportion of 13.33% would be used in phosphorus releasing straightly.Such a conclusion may be advantageously used in treating domestic wastewater for biological phosphorus removal.关键词
