【正文】 rain water, the larger the latter, but the concentration of anic pounds in water is relatively small. Therefore, pre confluence rain water, Many cities in China, the new city with the coexistence of the old city, Combined with the streaming system coexist. Therefore, new or expanded sewage treatment plant to meet the overall urban planning and drainage planning requirements should be able to meet the following require ments: Could be considered together with the diversion of sewage by pretreated sewage into the structure. Combined sewage late rainfall, with the exception of part of the sewage, together with the diversion of sewage by pretreatment structures into the sewage treatment structures, and the other part to consider the adoption of stormwater pollution entering the storm sewage overflow structures Shen overflow pool set into the nearby water body after. In order to enter the structure of the bined sewage effluent peak flow, water quality buffer fluctuations conditioning, sewage treatment structures regulating the frontend buffer pool can be installed in order to balance water quality, storage of water. (2) reliable BOD, COD, SS removal of nitrogen and phosphorus removal function and features to ensure the stability of the final effluent quality. Under normal circumstances, urban sewage in less refractory anic matter, BOD, COD removal is easier to achieve, rather than the plexity of nitrogen and phosphorus removal. The current effluent standards for sewage treatment plant effluent nitrogen and phosphorus indicators have strict requirements, it must be of urban sewage treatment to achieve the effective removal of nitrogen and 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 31 phosphorus. Under the existing urban sewage nitrogen and phosphorus removal process, A2 / 0 used more widely. For the A2 / 0 process problems, the present situation of a number of improvements in technology, technology also exists for each of the characteristics and limitations of each. As a result of merging the water quality caused by sewage, water, volatile, wastewater treatment plant on the impact of the processing units, in order to adapt to the receiving water requirements, in order to BOD, COD and other indicators of a further drop Property Management Environmental Protection Building energy saving Window and door profile Water Treatment Gas Network Sewage Treatment Town Planning House demolition Construction Low, further removal of sewage bacteria and nitrogen, phosphorus and other plant nutrients in the wastewater treatment plant and receiving water can be established between the oxidation pond. (3) with flexible operation mode, according to the quantity of sewage collection, water quality and seasonal variation of the adjustme nt operation. Conventional A2 / 0 process, it is difficult to do adjust the flexible operation mode. However, A2 / 0 process from the principle constitutes a sense, before the paragraph in the aeration and anoxic plus anaerobic paragraph. This principle for the oxidation ditch technology can be adapted to the formation of a variety of different water quality, quantity, seasonal changes in the operating mode. Wastewater treatment plant can be established according to the actual 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 32 situation of the oxidation ditch more than two, each for a certain amount of ditch water propeller, bottom uniform microporous gas explosion device. 3 .Selection and characteristics of that process Oxidation ditch is a simple, efficient and economical municipal wastewater treatment technology, has developed rapidly in recent decades. In the flow pattern, it is pletely mixed, but also has pushflow characteristics. As a result of the decreasing concentration of dissolved oxygen ditches changes and appropriate arrangements through the inlet, outlet, back to the entrance of the location of the sludge, oxidation ditch can be inverted to form a A2 / 0 process, see Figure 2, Figure 3: Combined sewage system in accordance with the characteristics of both a triage system, and treated water discha。s urban sewage treatment rate of 40 percent required, and therefore the study of the convergence of effective methods of sewage treatment, sewage treatment to accelerate the pace of the city is of great significance. In this paper, the convergence of the sewage treatment situation, some personal views. Window and door profile 2 requirements of the sewage treatment process (1) have to accept merging the old city sewage capabilities, a strong 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 30 ability to adapt to the impact load. Source of the sewage treatment plant effluent is posed of two parts: First, the new urban sewage diversion。祝各位老師萬(wàn)事如意,工作順利! 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)(論文) 28 參考文獻(xiàn) [1].孫慧修主編 .排水工程上冊(cè) (第 4 版 ).北京 :中國(guó)建筑工業(yè)出版社,1998年 7 月 .
