文档介绍：设计总说明
本次毕业设计的题目为关中某县城污水处理厂工艺及调节池设计。随着我的提高,加大城镇污水处理厂的建设已成为目前我国环保工作的重要内容。适用于该污水处理厂处理厂(处理量达20000m³/d)的处理工艺主要有氧化沟工艺、CASS工艺、SBR工艺和A20工艺等。经过工艺比选,本设计采用改良型卡鲁塞尔2000氧化沟工艺。本设计的主要任务是完成该污水处理厂初步设计及单项处理构筑物施工图的设计。
其中初步设计任务包括:设计说明书一份、污水处理厂总平面图一张及污水与污泥高程图一张、单项处理构筑物设计图4张、实习报告一份、英文文献翻译一篇。
出水水质应达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。
关键词:关中地区县城污水处理厂;卡鲁塞尔氧化沟工艺;设计计算。
Design Description
The topic of this graduate design is about the design of the sewage disposal plant and the regulating reservoir in some town of the level of urbanization and environmental pollution control has raised,increasing the urban sewage treatment plant construction has e an important part of our environmental protection technologies for small the sewage treatment plant(The construction of this plant is 20000m³/d) are mainly oxidation ditch process,Cyclic Activated Sludge System,Sequencing Batch Reactor Activated Sludge Process and Anaerobic-Anoxic- technology selection,the design uses improved Carrousel2000 Oxidation Ditch main task is the primary design of the plant and the single disposal build design.
The achievements of the primary design is a design book,a plan of the plant,the high drawing of the disposal of sludge and sewage , the single disposal build design,a intership report and an English literature translation.
.The outlet water of the plant meets the level one of the Discharge standard of pollutants for municipal wastewater GB18918-2002.
Key word:the sewage disposal plant in Guanzhong.;improved Carrousel Oxidation Ditch Process;design calculation.
