高效聚磷菌TP16强化除磷

INTENSIVE PHOSPHORUS REMOVAL USING TP16 WITH HIGH CAPABILITY OF ACCUMULATING POLY-P

采用SBR反应器,以合成废水作为反应器进水,研究高效除磷菌TP16厌氧聚PHB及释磷,好氧分解PHB和吸磷能力。试验结果表明:TP16好氧培养时,可以好氧聚集PHB,PHB浓度上升与乙酸的浓度下降呈负相关,乙酸吸收量与PHB/VSS的比值呈明显负相关关系;TP16厌氧培养时,底物乙酸浓度下降与菌体PHB的上升呈显著的负相关关系。磷释放试验表明,以乙酸作为底物,TP16厌氧培养时上清液中乙酸浓度的下降与磷浓度的增加呈负相关关系。

Adopting SBR reactor,and using synthetic wastewater as material of reactor,it was researched the capability of PHB-accumulating and P-releasing under anaerobic condition,and that of PHB-decomposing and P-absorbing under aerobic condition using TP16.The result of experiment indicating:When cultured in acetic acid under aerobic conditions,TP16 could accumulate PHB.Ascending of PHB concentration in the strains was negatively correlated with descending of acetic acid concentration.While TP16 grew under anaerobic conditions,descending of acetic acid concentration in the supernatant was negatively correlated with ascending of PHB and P concentration.
