This plant treats municipal sewage mainly. Its water quality is more complicated:Suspended substance ( ): 200mg/L;SThe biochemical oxygen demand of five days ( ): 140mg/L;5BODThe chemical oxygen demand ( ): 260mg/L; crCNH3-N: 30mg/L;Treated water quality is required:20mg/L; 5BODSS20mg/L; 60 mg/L;crCNH3-N15mg/L; 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 and , it should be treated with a proper process. We adopt and use a kind of craft, 5BODSwhich is a comparatively popular craft at present named Anaerobic-Anoxic-Oxic.The advantage 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 poolThis 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: Grid Pumping house New craft The second sinking pool.2/AO第一章 設(shè)計(jì)概論1.1 設(shè)計(jì)依據(jù)和任務(wù)(1)原始依據(jù)設(shè)計(jì)題目: 6萬(wàn)m 3/d城鎮(zhèn)污水推流式曝氣池處理工程設(shè)計(jì)設(shè)
