【正文】 黑龍江生態(tài)工程職業(yè)學(xué)院 畢業(yè)設(shè)計(jì)(論文) I 摘 要 水是人類最寶貴的自然資源之一,目前全世界正面臨著越來越嚴(yán)重的缺水問題。因此,對水資源的保護(hù),特別是對污水的凈化處理和研究工作就顯得十分重要,建設(shè)良好的污水處理廠勢在必行。 在許多大中城市的缺水問題嚴(yán)重,以及城市中人口密度大 ,產(chǎn)生的污水量也就很多,所以城市污水處理廠更顯得很重要。在我國,中小城市零星分布,因此,中小型污水處理廠更是建設(shè)中的重中之重。 中小型污水處理廠雖然不如大型的處理量大,但其成本少、易于建設(shè)。況且,中小型污水處理廠更適合我國城市眾多的特點(diǎn)。 處理工藝主要為活性污泥處理工藝以及其他先進(jìn)的 處理方法。本文對日處理 8 萬噸的中型污水處理廠的工藝流程進(jìn)行了簡單的介紹。 關(guān)鍵詞 :污水處理廠;活性污泥;氧化黑龍江生態(tài)工程職業(yè)學(xué)院 畢業(yè)設(shè)計(jì)(論文) II Abstract The water is one of the natural resourceses that the mankind are most precious, the whole world faces the more and more serious water shortage problem face to face currently. Therefore, to the protection of the resources of water, seem to be very important to the decontamination processing and the research works of the dirty water especially, constuct the good and dirty water processing factory power at go necessarily. The water shortage problem severity of the city in mainly bigly, and a density of the city middleman is big, output and dirty water quantity also a lot of, so the dirty water of city processing the factory even seems to be very important. At the our country, distribute piecemeal in the small city, therefore, handle in the small scaled and dirty water the factory is also a construction in of heavy in it is heavy. The medium small scaled and dirty water processing factory although the not equal to large processing have great capacity, its cost is little and be easy to the construction. Besides, win the small scaled and dirty water processing factory more in keeping with our country the city numerous characteristicses. Mainly handle the craft to handle craft and the processing method of other forerunnerses for the live and dirty mire. This text handles the craft process that 80,000 mediumsized dirty waters of the tons handle the factory to carry on the simple introduction to the day. Key word: The dirty water processing factory。 Live and dirty mire。 Oxidize the ditch黑龍江生態(tài)工程職業(yè)學(xué)院 畢業(yè)設(shè)計(jì)(論文) III 目 錄 第 1 章 前 言 1 第 2 章 水質(zhì)標(biāo)準(zhǔn)、方案選擇與工藝流程 2 水質(zhì)標(biāo)準(zhǔn)與工藝流程 2 方案選擇 2 原始數(shù)據(jù)確定 3 第 3 章 設(shè)計(jì)流量的計(jì)算和污水水質(zhì)污染程度的確定 4 污水流量的計(jì)算 4 污水水質(zhì)污染程度的確定 4 第 4 章 主要構(gòu)筑物設(shè)備及工藝設(shè)計(jì) 5 格柵 5 沉砂池 9 巴氏計(jì)量槽 10 初沉池 10 A/O 氧化溝 12 二次沉淀池 16 污泥處理設(shè)計(jì) 18 自動控制系統(tǒng) 22 第 5 章工藝設(shè)計(jì)特點(diǎn) 183
