江苏镇江大港8万吨污水处理工程设计(含CAD图)(计算说明书10000字,CAD图11张)
摘要
随着社会进步,人们对于城市污水的处理的要求愈加严格。除了基本的去除污水中BOD和SS的要求外,通常还要求脱氮除磷,以保护水体环境。本设计即采用了众多脱氮除磷工艺中较为经济合理的AAO工艺对进入污水厂的污水进行处理。设计污水处理厂处理所在城市生活污水,日处理能力8万方,有效去除水中BOD、SS以及氮、磷元素,出水质量将达到国家污水综合排放标准一A级标准。本设计对污水处理厂处理流程、处理构筑物、以及高程进行了初步设计。
Abstract: With social progress, the demand for people's treatment of the municipal sewage is stricter..Except the demands of BOD and SS in the sewage, demand denitrification get rid of the phosphorus yet usually to go besides a basic one, in order to protect the water body environment .W have adopted A2/O craft to deal with the sewage which enters the sewage factory in this design. This paper Introduces the principles of biological phosphorus and nitrogen removal with the A2/O process and describes the flow chart of this process which Is then analyzed In detail.
