晋中市某污水处理厂工程设计(含CAD图)(任务书,开题报告,外文翻译,设计说明书22000字,CAD图9张)
摘   要
根据设计要求和求新的思想，该污水处理工程进水中氮含量均偏高，在去除BOD5和SS的同时，还需要进行脱氮处理，故采用当代水处理工艺中较流行的   工艺。 工艺由于不同环境条件，不同功能的微生物群落的有机配合，加之厌氧、缺氧条件下，部分不可生物降解的有机物能被开环或断链，使得N、P、有机碳被同时去除，并提高对不可降解有机物的去除效果。它可以同时完成有机物的去除，硝化脱氮、磷的过量摄取而被去除等功能，脱氮的前提是NH3－N应完全硝化，好氧池能完成这一功能，缺氧池则完成脱氮功能。厌氧池和好氧
池联合完成除磷功能。
此外该工艺还具有高效、节能的特点，且耐冲击负荷较高，出水水质好。因此,更具有广泛的适应性，完全适合本设计的实际要求。本工艺的主要构筑物包括格栅、污水泵房、平流沉砂池、好氧池、厌氧池、缺氧池、二沉池、接触消毒池、浓缩池、污泥脱水机房等。
本设计采用了 为主体工艺，工艺流程相对简单，省去了污泥消化系统，节省了基建投资和运行费用，该工艺处理污水运行稳定，易于管理，出水水质达到设计要求，真正做到了污水的综合利用。 [资料来源：Doc163.com]

Abstract
According to the designing requirement and thought of looking for novelty: the content of nitrogen in the municipal sewage is on the high side in this project .so while getting rid of BOD5 and SS, it should be treated with a proper process. We adopt and use a kind of craft, which is a comparatively popular craft at presentnamed Anaerobic-Anoxic-Oxic.
Theadvantage of this comprehensive craft is extensive adaptability , totally suitable for reality originally designed purpose. Its main structures includes gate well , grid , sewage pumping house , earate and sinking sand pool , oxidizing ditch , the second sinking pool, contacting pool , concentration tank , mud to dehydrate in the computer lab etc.
Process due to different environmental conditions, different functions of microbial communities in the organic, combined with anaerobic, anoxic condition, some non-biodegradable organic matter can be open or broken chain, making N, P, organic carbon is also removed, and to enhance non-degradable organic removal. It can simultaneously remove organic matter, nitrification and denitrification, excessive intake of phosphorus was removed and other functions, provided that removal of NH3 - N should be fully nitrification, aerobic tank to complete the function, oxygen tank is complete removal function. Anaerobic tank and aerobic phosphorus removal capabilities to complete the joint pool [资料来源：http://www.doc163.com]
This design have adopted the practical craft and equipment of good performance, and the procedure is simple, management is convenient, do not need to add the first sinking pool ,digestive system .reducing building and operating expenses, realizing automation totally at the same time, easy to manage, making the treated water reach sewage discharge standard , accomplish the rational utilization of water resource.
Keywords: GridPumping houseNew craftThe second sinking pool.
