摘要该市区属温带季风型大陆性气候，春季多风干燥，夏季受北太平洋暖流影响，温暖而潮湿，秋季温润凉爽，冬季受蒙古和西伯利亚高气压带控制，寒冷干燥。年平均降水量约 550 毫米，年平均气温 8℃。故使用 SBR 工艺设计一个东北某市的污水处理厂。SBR 是序列间歇式活性污泥法（Sequencing Batch Reactor Activated Sludge Process）的简称，是一种按间歇曝气方式来运行的活性污泥污水处理技术，又称序批式活性污泥法。与传统污水处理工艺不同，SBR 技术采纳时间分割的操作方式替代空间分割的操作方式，非稳定生化反应替代稳定生化反应，静置理想沉淀替代传统的动态沉淀。它的主要特征是在运行上的有序和间歇操作，SBR 技术的核心是 SBR 反应池，该池集均化、初沉、生物降解、二沉等功能于一池，无污泥回流系统。经过这个废水处理工艺的废水可达到设计要求，可以直接排放。产生的污泥经过浓缩、压滤等处理后，进行堆肥产生一定的经济效益。关键词：东北某市；SBR 工艺；生活污水；污泥AbstractThe city belongs to the temperate zone monsoon type continental climate, Spring is windy and dry, Affected by the north Pacific warm in summer, Warm and humid, Cool autumn warmth, Controlled by Mongolia and Siberia high pressure belt, winter cold and dry. Average annual rainfall of about 550 mm, Average annual temperature 8 . So the use of℃ SBR process design a northeast city sewage treatment plant.SBR is the abbreviation of the intermittence type active mud law (Sequencing Batch Reactor Activated Sludge Process) of the array ,it is one kind that exposes to the sun the active mud sewage treatment technology that the angry way operates according to the intermittence ,also called the criticizing type law of active mud of preface.Different from traditional sewage disposal craft,SBR technology adopt operation mode that time cut apart substitute operation mode that space cut apart , stabilize biochemistry is it substitute stable state biochemistry react , quiet to put ideal precipitate...
