一、废水生物除磷机理在厌氧条件下,由于废水中没有DO或氧化态氮(NO_x~-),一般无聚磷能力的好氧菌及脱氮菌,不能产生ATP(腺嘌呤核苷三磷酸),所以这类微生物不能摄取细胞外的有机物,即不能进行主动传输。但是,在厌氧条件下,有一类所谓除磷菌的细菌却能分解细胞内的聚磷酸盐同时产生ATP,并利用ATP将废水中的脂肪酸等有机物摄入细胞,以PHB(聚-β-羟基丁酸盐)及糖原等有机颗粒的形式贮存于细胞内。同时还将分解聚磷酸盐所产生的磷酸排出胞外,这时细胞内还会 First, biological phosphorus removal mechanism of wastewater Under anaerobic conditions, the wastewater is not due to DO or nitrogen oxide (NO_x ~ -), generally non-polyphosphate-capable aerobic bacteria and nitrogen and nitrogen bacteria, can not produce ATP (adenosine riboside Triphosphate), so these kinds of microorganisms can not take extracellular organic matter, that is, can not be active transmission. However, under anaerobic conditions, there is a class of so-called bacteria that remove phosphorus-containing bacteria that can break down the polyphosphate in the cells and generate ATP. The ATP is used to inactivate organic acids such as fatty acids in the wastewater. The PHB (poly- Hydroxybutyrate) and organic particles such as glycogen stored in the cell. At the same time will also break down the phosphate generated by polyphosphate excreted, then the cells will be
