日处理2000吨生活污水处理厂初步设计生物接触氧化法.docx

摘要
本设计内容是山东兖州矿业集团杨村煤矿区2000吨/日生活污水处理厂初步设计。根据杨村煤矿区生活污水的水质特点,经技术和经济等方面的对比,采用生物接触氧化工艺。
生物接触氧化是采用生物膜水处理废水的一种方法,是以附着在载体(填料)上的生物膜,净化有机废水的一种高效水处理工艺。本设计的主要内容包括设计的目的及要求,建筑条件与工艺流程选择,污水构筑物设计计算,工程经济分析和环境影响评价等。其中设计要完成设计说明书一份,污水处理厂总平面图一张,污水处理厂污水高程图一张,工艺流程图一张,及四张单个处理构筑物平面图,剖面图的设计图。污水处理厂出水要达到国家《污水综合排放标准》(GB8978)中二级排放标准的规定。所选的生物接触氧化工艺具有工艺稳定性高,处理构筑物少,流程简化,节省投资等优点。
关键词:生物接触氧化生物膜煤矿区生活污水
Abstract
This design is the primary design of Shandong Yanzhou Mining Group Yangcun Coal Mining Area 2000 tons / day sewage treatment plants . Biological contact oxidation process was used based on the sewage quality characteristics of the Yangcun coal mining area and the technical and parison.
Biological contact oxidation biofilm is a kind of wastewater treatment method, which is a highly efficient wastewater treatment process anic materials purification with the biomembrane attached to the carrier (commonly known as fillers).The main content of the design including the purpose and requirements of the design, building conditions and process selection, design and calculation of sewage structures, engineering economic analysis and environmental impact assessment. Which design plete the design of a manual, a general layout of the sewage treatment plant, sewage treatment plant sewage elevation map a process flow diagram one, and four single treatment tank plan, profile treatment plant effluent to achieve national "Integrated Wastewater Discharge Standard (GB8978) the provisions of the two emission standards. Selected biological contact oxidation process has some advantages, such as high process stability , less structure, process simplification and saving investment.
Key words: Biological contact oxidation Biomembrane
Domestic sewage in coal mine area
