簡介：本論文以招遠市污水處理廠運行檢測數(shù)據(jù)，利用BIOWIN3軟件建立百樂克污水處理工藝數(shù)學模型，運用諸城市銀河污水處理廠運行數(shù)據(jù)對該模型進行驗證，結(jié)果表明，該模型較好模擬百樂克工藝運行情況，對進一步應(yīng)用于百樂克工藝污水處理廠運行和設(shè)計具有指導意義。論文探討了計算機模擬技術(shù)的理論基礎(chǔ)；系統(tǒng)地研究了百樂克工藝的工藝原理、工藝特點以及在污水處理中的應(yīng)用情況；以招遠市污水處理廠為例，采用該廠運行數(shù)據(jù)為入流數(shù)據(jù)，經(jīng)比較選擇利用BIOWIN3軟件建立百樂克工藝模型，按溫度不同分別對四個季節(jié)進行模擬，通過調(diào)整動力學參數(shù)和化學計量學參數(shù)，使模擬結(jié)果與實測值相吻合，相對誤差在10％以內(nèi)。以諸城市銀河污水處理廠運行數(shù)據(jù)對該模型進行驗證，結(jié)果與實測值相對誤差在15％以內(nèi)。利用BIOWIN3軟件模擬結(jié)果表明1、該軟件是適合國內(nèi)水質(zhì)情況的，可以應(yīng)用于國內(nèi)活性污泥法的城市污水處理廠。2、可指導污水處理廠運行可預測出水水質(zhì)情況，可在線觀測到各處理單元的處理效果情況，可求出最佳的運行參數(shù)。3、在輔助設(shè)計方面的應(yīng)用可得出設(shè)計參數(shù)，可預測出水水質(zhì)，求得最佳的運行參數(shù)。

簡介：天津作為北方大城市屬于資源性缺水城市，年人均占有水量為156M，僅為全國人均占有量的116，世界人均占有量的150，遠遠低于世界公認的人均占有量1000M的缺水警戒線，屬于重度缺水地區(qū)。由于海河流域水體污涇比嚴重失衡，致使處于下游的天津水污染嚴重，更加劇了缺水矛盾。未來一段時期內(nèi)，由于天津市人口的快速增加，人民生活水平的提高及工農(nóng)業(yè)生產(chǎn)的發(fā)展，天津市的缺水形勢將加劇。面對水資源短缺的現(xiàn)狀，能否解決天津市用水緊張狀況，關(guān)系到天津市經(jīng)濟能否長期穩(wěn)定、持續(xù)發(fā)展。，因此進行再生水回用的研究及應(yīng)用，無疑具有積極而現(xiàn)實的意義。本研究以衛(wèi)國道再生水生產(chǎn)點為工藝依托，主要著眼于工藝優(yōu)化設(shè)計，進行了一系列試驗研究，并在實驗結(jié)果基礎(chǔ)上提出了切實可行的設(shè)計方案，同時對存在的問題及可能的解決辦法亦進行了具有針對性地主要是水中氨氮、磷及COD去除方法實際探討，為以后進一步提高再生水出水水質(zhì)、降低生產(chǎn)成本提供參考。其中主要的研究內(nèi)容為以東郊污水處理廠二級出水為水源，以衛(wèi)國道洗車站為實驗基地，按園林綠化、河道景觀、居住區(qū)等不同再生水回用水質(zhì)要求，通過混凝沉淀、砂濾、活性炭、微濾、臭氧消毒等處理單元的工藝組合，探索研究最佳絮凝劑、最佳投藥量、臭氧發(fā)生量、加氯量等工藝運行技術(shù)參數(shù)，探索再生水回用處理工藝運行操作具體方法和規(guī)律，進行成本分析、技術(shù)分析。以探索最佳處理工藝，摸索運行管理、操作技術(shù)與方法。
