Achieving harmless treatment of mariculture sediment. 实现海水养殖底泥的无害化处理 This book optimizes the cultivation conditions of aerobic granular sludge and attempts to improve its long-term operational stability by controlling granule size. The book consists of eight chapters, providing a detailed introduction to the formation process and stability control optimization methods of denitrifying phosphorus-removal aerobic granular sludge. Grey relational analysis is employed to identify key influencing factors during the granulation process, with optimal values or optimal control ranges provided. The durations of anaerobic, aerobic, and anoxic phases in the sequencing batch reactor are adjusted using pH, oxidation-reduction potential, and dissolved oxygen to optimize operational parameters of aerobic granular sludge while addressing the issue of non-filamentous bulking. To address the poor long-term stability of aerobic granular sludge, a coupled selection pressure that effectively controls the continuous growth of granule size is selected based on previously obtained optimal conditions. In addition, methods for measuring the activity of denitrifying phosphorus-removing microorganisms in aerobic granular sludge are thoroughly investigated, the drawbacks of conventional measurement methods are analyzed, and improved experimental methods are proposed to accurately assess the activity of various microbial populations. The effect of tourmaline addition on the cultivation and treatment performance of denitrifying phosphorus-removing aerobic granular sludge is also examined. Finally, using aquaculture sediment as the inoculum, stable salt-tolerant denitrifying phosphorus-removing aerobic granular sludge is cultivated, and its performance in treating mariculture tailwater is investigated. This research has positive implications for the protection of China's mariculture water environment. The experimental outcomes can reduce the ecological risk of mariculture sediment, achieve its harmless treatment and resource utilization, lower sediment treatment costs, and provide technical support for improving the recirculation of mariculture tailwater. This book provides reference methods and theoretical bases for improving the stability of aerobic granular sludge through the optimization of cultivation conditions for denitrifying phosphorus-removal aerobic granular sludge and the measurement of the activity of nitrogen- and phosphorus-removing functional microorganisms. It also serves as a technical reference for engineering and technical personnel in the fields of domestic wastewater treatment and aquaculture tailwater treatment, as well as for students and faculty in aquaculture engineering, chemical engineering, environmental engineering, and related disciplines. This work possesses significant academic and practical value. 本书通过优化好氧颗粒污泥的培养条件,尝试从控制粒径的角度提高其长期运行过程的稳定性。本书共8章,详细介绍了反硝化除磷好氧颗粒污泥的形成过程和稳定性控制优化研究方法。其中,引入灰关联分析判定好氧颗粒污泥形成过程中的关键影响因子,给出其最佳值或最佳调控范围。并利用pH 值、氧化还原电位和溶解氧调整SBR的厌氧、好氧和缺氧时长,优化好氧颗粒污泥的运行参数,同时解决非丝状菌膨胀问题。针对长期运行过程中好氧颗粒污泥稳定性差的问题,基于已获得的优化条件,筛选出有效控制粒径不断增长趋势的耦合选择压。此外,针对好氧颗粒污泥中反硝化除磷微生物活性的测定方法进行深入研究,分析传统测定方法的弊端,并提出准确地评估各类菌体活性的实验改进方法。考察了电气石的投加对反硝化除磷好氧颗粒污泥培养和处理性能的影响。最后,采用养殖底泥为接种污泥,培养稳定耐盐反硝化除磷好氧颗粒污泥,进而开展海水养殖
