摘要:
基在将来可能的支流厌氧氨氧化利用,总结与阐发了AB工艺的A段中微生物的研究近况、净化机理和A段中具有的胞外聚合物(EPS)的感化与影响。A段对污水中碳源的收受接管,具有着吸附、絮凝、沉降和生物感化等多种进程,此中,增添进水SS、升高EPS含量、提高pH值、插手二价或三价阳离子、下降多糖含量等方式都可提高污泥的絮凝、沉降、吸附机能。在强化A段捕获无机物的研究中发觉,投加化学絮凝剂是较为可行的强化方式,能够将BOD5去除率提高到60%～70%。想要进一步下降BOD5/N比值还需要在B段进一步下降无机物的值,可在新提出的两种工艺的短程硝化阶段或是无机物氧化阶段经由过程调理DO值,氧化分化无机物使得ANAMMOX菌具有杰出活性,以实现支流ANAMMOX工艺。
Abstract:
Based on the possible application of anaerobic ammonia oxidation in the main treatment process in future, this paper summarized and analyzed the research status of microorganisms and purification mechanism in A-stage of AB process, as well as the effect of the extracellular polymer substances(EPS)in the A-stage. There were many processes such as adsorption, flocculation, sedimentation and biodegradation in the A-stage. Among them, it could be found that increasing influent SS, the EPS content and pH, adding two or trivalent cationic flocculants, and reducing the content of polysaccharidecould improve the adsorption, flocculation sedimentation performance of sludge. In the study on strengthening the performance to capture organic matter in A-stage, it was found that the addition of chemical flocculants was a feasible method to increase the removal����APP rate of BOD5to 60%-70%. To further reduce the BOD5/N ratio, it was necessary to further reduce the value of organic matter in B-stage, which could be realized by adjusting the DO value in the short-term nitrification stage of the two new processes or in the oxidative stage of organic matter. The oxidative decomposition organic compounds makes ANAMMOX bacteria had good activity to achieve the mainstream ANAMMOX process.
