The utility model discloses a short-range denitrifying phosphorus enrichment rapid acclimation device, including SBR reactor, water tank and nitrite plus kits, SBR reactor is composed of a double-layer organic glass, and the outer electric thermostatic water bath is connected, the formation of water bath heating, to ensure the system is in a state of constant temperature. The electric mixer is installed on the upper part of the reactor, so that the slurry can be fully mixed in the reaction process. The microporous aeration tray installed at the lower part is connected with the gas flow meter, and the aeration quantity is controlled by the DO on-line monitor, so that the dissolved oxygen is within the allowable range. The pH on-line monitor ensures that the system is in the proper range of pH. The alarm signal is sent out of the set range, and the acid pump is added to the peristaltic pump to adjust the pH to make it in the allowable range. The automatic operation management greatly reduces the labor intensity, saves the cost of pollution control, and the equipment structure is simple and convenient to move.

一种短程反硝化聚磷菌快速驯化富集装置
本专利技术涉及污水处理及环境保护领域,是一种以亚硝态氮为电子受体脱氮除磷的短程反硝化聚磷菌快速驯化富集装置。
技术介绍
目前,生物强化除磷技术(enhancedbio1ogica1phosphorusremova1,EBPR)因其效率高、成本低和环境友好的特点而备受学者关注,该技术中主要的功能微生物是聚磷菌(Accumu1ibacter)。在厌氧条件下细胞内聚磷水解产生能量(adenosinetriphosphate,ATP)和还原型辅酶NADH,用于挥发性脂肪酸(volatilefattyacid,VFA)的吸收并储存为聚一β一羟基丁酸(poly-S-hydroxybutyrate,PHB);然后在好氧条件下以PHB为电子供体,以氧为电子受体进行过量吸磷,从而以剩余污泥排放的形式去除污水中的磷。随着学者对聚磷菌的深入研究,发现存在着一种聚磷菌可以在缺氧条件下以硝酸盐为电子受体进行同步反硝化脱氮除磷,称为反硝化聚磷菌。与以O2、硝态氮为电子受体相比,利用亚硝态氮为电子受体的反硝化聚磷菌具有运行周期短,吸磷速率快的优势,更加节省 ...
