摘 要本次设计是根据永春县的生活污水排放情况和原有污水处理厂的污水处理能力为分析基础，再综合分析各个工艺的特征设计出一套污水处理工艺，经过分析比较筛选出AB 工艺。设计内容主要包括工艺流程的设计、构筑物及建筑物的平面布置。本次工艺的流程：污水经过格栅、沉砂池去除掉一些体积较大的颗粒，接着进入到本次工艺的关键阶段：吸附池、沉淀池（A 阶段），A 阶段高负荷的运行下，能去除掉大多数的有机物，然后污水进入到曝气池、沉淀池（B 阶段）再进行进一步的处理，最后出水。出水水质符合排放标准。整个设计工艺，流程简略，运作灵活，管理便利，节约经济成本，契合中小型城镇污水处理厂的要求。关键词：生活污水；AB 工艺；工艺设计sAbstractThis design, the domestic sewage treatment status of Yongchun County, and the analysis of the sewage treatment capacity of the sewage treatment facility of Yuanyuan, the analysis of the special features of each project, the design of the sewage treatment project. After analysis and comparison, AB process is selected. The design content mainly includes process design, structure and building design. The sequence of this process is: the wastewater removes larger particles through the network and the granary, and then enters the key stages of this process: the adsorption tank and the sedimentation tank (stage A), under the high-load operation of stage A , Can remove most of the organic matter, and then the sewage enters the aeration tank, sedimentation tank (stage B) for further treatment, and finally the effluent. The effluent quality meets discharge standards.The whole design process is simple in process, flexible in operation, convenient in management, saves economic cost, and meets the requirements of small and medium-sized urban sewage treatment plants.Key words: Domestic sewage；AB Technology;technological design目 录1 引言............................................................................
