| 摘 要： | 利用ASM2D数学模型对上海石洞口污水厂UniTank工艺流程中磷酸盐浓度进行了仿真研究,发现该流程中磷酸盐浓度具有非稳态特征.增加反应器的曝气强度,会增加UniTank流程边池的硝态氮浓度,弱化边池的厌氧释磷,相应增加出水中磷酸盐含量.

| Abstract: | Dynamic characteristics of ortho-phosphate concentration in a UniTank process in Shanghai Shidongkou urban sewage treatment plant was studied by using a mathematical model basing on ASM2D. The results show that ortho-phosphate in the UniTank process is on non-steady state. Variation of the concentration of the species can be as large as 20%. Strengthening aeration may increase the nitrate-nitrogen concentration in the vessels, and interfere the anaerobic condition that is necessary for ortho-phosphate release from the phosphorus accumulating organism(PAO). This may result in the increase of the ortho-phosphate concentration in the effluent . |
