摘要:河南省D市A區(qū)排水工程設(shè)計分雨水污水管網(wǎng)設(shè)計與污水處理廠設(shè)計兩大部分，旨在對本科期間給水排水工程所學(xué)內(nèi)容進(jìn)行了一個總結(jié)。 河南省D市A區(qū)夏季多雨，冬季干燥。采用完全分流制排水系統(tǒng)。污水管網(wǎng)經(jīng)各分區(qū)收集，匯集到城市的主干管，然后進(jìn)入污水處理廠進(jìn)行處理。雨水管網(wǎng)根據(jù)地形坡度，分為三個大區(qū)，各區(qū)匯集的雨水直接經(jīng)由主干管排放至河流中。排水管采用鋼筋混凝土管。 污水處理廠采用UCT工藝，通過三級處理最終水質(zhì)達(dá)到國家1級A排放標(biāo)準(zhǔn)。 預(yù)處理以格柵、沉砂池、二沉池組成，粗、細(xì)格柵的傾角均為60°，粗格柵槽長4.2m，細(xì)格柵槽長3.5m，采用機(jī)械清渣。提升泵房選用350S16型單級雙吸水泵4臺，3用1備，3用1備。 旋流式沉砂池設(shè)一組分兩格運(yùn)行，每格設(shè)計流量為Q=281L/s； 二級處理采用UCT生化反應(yīng)池，厭氧池平均停留時間為2h，容積為4640.4m3；缺氧池均停留時間為2.74h，容積為4868.75m3； 二沉池采用輻流式沉淀池，池子直徑為30m，沉淀部分有效水深2.86m，沉淀時間2h，污泥斗容積為143.58m3。進(jìn)水管直徑400mm，流速為0.1m/s。 剩余污泥經(jīng)濃縮消化處理后，經(jīng)過機(jī)械脫水然后外運(yùn)。由于城市污水40%做中水回用，處理后的污水40%流經(jīng)活性砂濾池進(jìn)行深度處理，其他60%處理完成后直接排放至水體。 工程投入使用后將大大緩解夏季城市的內(nèi)澇問題，并減輕由于水污染造成的環(huán)境惡化情況。 關(guān)鍵詞： 完全分流制排水系統(tǒng)；UCT生化反應(yīng)池；輻流式沉淀池
Abstract:Henan province D city A area drainage engineering design of rainwater and sewage pipe network design and the design of wastewater treatment plant of two parts, aims to make a summary of the contents of undergraduate course of water supply and drainage engineering. Henan province D city A District rainy summer, winter dry. Using completely separate drainage system. Sewage pipe network by the district collection, collection to the city's main pipe, and then enter the sewage treatment plant for processing. Rainwater pipe network according to the terrain slope, is divided into three regions, each collected rainwater directly through the main pipe is discharged into the river. Drainage pipe reinforced concrete pipe. Sewage treatment plant using UCT technology, to achieve 1 National A emission standards through three levels of processing the final water quality. Pretreatment with grille, grit chamber, composed of two sedimentation tank, coarse, fine grid dip angle is 60 degrees, the coarse grid slot length 4.2m, the fine grid slot length 3.5m, using mechanical slag. Ascension pump selection of 350S16 type single stage double suction pump 4, 3 with 1, 3 with 1 preparation. Rotational flow grit chamber, a group of two parts, the design flow of Q=281L/s. Two levels of treatment using UCT biochemical reaction tank, anaerobic tank for 2h average residence time, the volume is 4640.4m3; time of anoxic tank were stay for 2.74h, volume 4868.75m3. The radial flow sedimentation pool two sink the pond, pool diameter 30m, precipitate effective depth 2.86m, precipitation time 2h, the sludge bucket volume is 143.58m3. The water inlet pipe diameter 400mm, the flow rate was 0.1m/s. Residual sludge concentration digestion treatment, after mechanical dewatering and then sinotrans. Because the city sewage 40% water reuse, sewage after treatment 40% through the active sand filter for advanced treatment, 60% other processing is done directly discharged into water body. After the project put into use will greatly alleviate the problem of city waterlogging in summer, and reduce the water pollution caused by the deterioration of the environment.
