1、荣成市污水处理厂初步设计摘要荣成市地处山东半岛最东端,三面环海,海岸线长500公里。拥有石岛、龙眼两个一类开放口岸,山东省GDP排名第一的县级市(威海市代管),中国魅力城市,优秀旅游城市,生态园林城市,人居范例城市,环保模范城市,新兴工业强市,沿海开放城市,海洋经济大市,国家级海洋食品名城,人口较多。所以使用SBR工艺设计一个荣成市的污水处理厂。SBR是序列间歇式活性污泥法(SequencingBatchReactorActivatedSludgeProcess)的简称,是一种按间歇曝气方式来运
2、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技术采用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态生化反应,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:荣成市;SBR工艺;生活污水;污泥City25,0
