**Coursera课程总结：活性污泥法：基础知识与操作入门** 本课程是“水处理大师：饮用水、废水与工业水处理”综合项目的一部分，旨在深入浅出地介绍废水二级生物处理的核心技术——活性污泥法。 **课程核心内容：** * **二级处理的目的：** 讲解活性污泥法如何有效去除废水中可生物降解的有机物（溶解态和胶体态），并去除未被前处理阶段截留的悬浮固体，同时降低部分病原体含量。 * **生物反应器关键控制条件：** 详细阐述维持活性污泥法正常运行所需的关键环境因素，包括各项参数的详细说明。 * **活性污泥法的关键概念与参数：** 涵盖了从微生物学基础到操作实践的广泛主题，包括： * **处理流程（Treatment Train）：** 了解整体处理工艺。 * **代谢过程（Anabolism, Catabolism）：** 理解微生物的生命活动。 * **微生物与絮状结构（Microorganisms and floc structure）：** 掌握活性污泥的核心组成。 * **质负荷（Mass load）、污泥龄（Sludge age）：** 关键的运行控制参数。 * **混合液挥发性悬浮固体浓度（Volatile suspended solids concentration in mixed liquor）、30分钟沉降容积（30-minute sedimentation volume）、污泥容积指数（Sludge volume index）：** 表征污泥性能的指标。 * **pH、温度、溶氧浓度与耗氧速率（pH, Temperature, Oxygen concentration and Oxygen consumption rate）：** 影响微生物活性的环境因素。 * **容积负荷（Volumetric load）、水力停留时间（Hydraulic retention time）：** 评估反应器效率的参数。 * **回流流量与回流比（Recirculated flow and recirculation ratio）：** 活性污泥回流操作的关键。 * **污泥排放（Sludge purge）：** 污泥处理的重要环节。 * **反应器接种（Reactor inoculation）：** 启动活性污泥过程。 * **外观指标（Color, Odor, Foam, Bubbling in the secondary sedimentation tank）：** 视觉上判断工艺运行状况。 * **脂肪外观（Fat appearance）：** 特定污染物存在的迹象。 * **活性污泥法工艺变种：** 介绍并比较了几种常见的活性污泥法工艺，包括： * 传统活性污泥法（Conventional Activated Sludge） * 完全混合式（Complete Mix） * 递减曝气式（Decreasing Aeration） * 稳定接触式（Stabilization-Contact） * 延时曝气式（Extended Aeration） * **课程目标：** 以简洁明了的语言，避免过多的技术术语，直接阐述活性污泥技术的目的和操作方法，帮助学习者清晰理解并优化工艺效率。 本课程适合所有希望掌握活性污泥法基本原理和操作技能的学员。
Note: This course is part of a more comprehensive program titled: Water Treatment Mastery: Potable, Wastewater & Industrial, with a duration of 25.5 hours.Secondary wastewater treatment is the core of the biological treatment process, primarily aimed at removing biodegradable organic matter in dissolved and colloidal form. It also removes suspended solids that were not eliminated in previous stages, as they will form part of the floc and be removed from the system through excess sludge purge. Additionally, a certain amount of pathogens will also be removed, as the reactor conditions are not conducive to their growth.For the process to function correctly, the biological reactor must maintain certain controlled conditions, which will be described as each video develops.The Activated Sludge course covers the following topics: Treatment Train, Anabolism, Catabolism, Microorganisms and floc structure, Mass load, Sludge age, Volatile suspended solids concentration in mixed liquor, 30-minute sedimentation volume, Sludge volume index, pH, Temperature, Oxygen concentration and Oxygen consumption rate, Volumetric load, Hydraulic retention time, Recirculated flow and recirculation ratio, Sludge purge, Reactor inoculation, Color, Odor, Foam, Bubbling in the secondary sedimentation tank, Fat appearance. PROCESS VARIATIONS: Conventional Activated Sludge, Complete Mix, Decreasing Aeration, Stabilization-Contact, Extended Aeration.This course aims, without beating around the bush or overloading with technical terms, to directly introduce the purpose of the technology and how to operate it, using simple language to ensure clear understanding and improve the efficiency of your process.
