咸宁市某污水处理厂一期提标升级改造和二期新建工程(含CAD图)(任务书,外文翻译,论文计算书12800字,CAD图9张)
摘要: 随着城市的发展,传统污水处理技术已经很难满足国家一级A排放标准,为了控制水体的有机污染,许多经济发达国家普遍采用污水二级处理系统,其中以活性污泥法最为突出,而A2/O就是重要的活性污泥法。在我国污水处理技术中 A2/O 生物脱氮除磷技术是近十年来发展起来的一种生物处理新工艺,A2/O是采用厌氧-好氧-好氧法去除污水中的磷和氮,达到污水处理的目的。城市污水处理是一种高能耗行业,通过工艺调控,合理配置能源,具有很强的现实意义

Progress of A2/O process
Abstract: With the development of cities, traditional sewage treatment technology has been difficult to meet the national level A discharge standard. In order to control the organic pollution of water body, many developed countries generally adopt secondary sewage treatment system, among which activated sludge process is the most prominent, and A2/O is an important activated sludge process. A2/O biological denitrification and phosphorus removal technology is a new biological treatment technology developed in recent ten years in China. A2/O is an anaerobic-aerobic-aerobic process to remove phosphorus and nitrogen from wastewater, so as to achieve the purpose of wastewater treatment. Municipal sewage treatment is a high energy-consuming industry. It is of great practical significance to rationally allocate energy through process control.
