151.1排水體制論證在設(shè)計(jì)時(shí)，首先需合理地進(jìn)行選擇排水系統(tǒng)的體制，排水體制是城市和工業(yè)企業(yè)排水系統(tǒng)規(guī)劃和設(shè)計(jì)中的重要問題。排水系統(tǒng)的選擇應(yīng)滿足環(huán)境保護(hù)的需要，且應(yīng)根據(jù)當(dāng)?shù)貤l件，通過技術(shù)，經(jīng)濟(jì)比較確定體制，其中應(yīng)著重考慮環(huán)境保護(hù)這項(xiàng)因素。城市排水系統(tǒng)的排水體制有：分流制、合流制和混流制。分流制排水系統(tǒng)：是將城市生活污水、工業(yè)廢水和雨水分別在兩個(gè)及以上各自獨(dú)立的管道內(nèi)排水的系統(tǒng)。分流制將城市污水全部送至污水廠進(jìn)行處理，排放，與合流制相比較為靈活，且符合環(huán)境保護(hù)的要求。截流干管直徑適合，能適應(yīng)城市未來發(fā)展的需要，該體制也符合水質(zhì)衛(wèi)生的規(guī)范，在國內(nèi)得到了普遍的應(yīng)用。從經(jīng)濟(jì)方面來看，分流制可節(jié)省初期投資費(fèi)用。分流制系統(tǒng)可以使管內(nèi)的流速保持穩(wěn)定，不易發(fā)生淤積，沉淀，同時(shí)，流入污水廠的水量和水質(zhì)比合流制變化小得多，因此污水廠的運(yùn)行和維護(hù)易于控制。合流制排水系統(tǒng)：是將城市生活污水、工業(yè)廢水和雨水在同一個(gè)管道內(nèi)排除的系統(tǒng)。其中部分混合污水未經(jīng)水處理直接排放入環(huán)境中，因而污染水源，不利于環(huán)境保護(hù)和后期維護(hù)?；炝髦疲菏侵妇C合利用分流制和混流制的排水體制。因?yàn)樵摰貐^(qū)雨季時(shí)，雨量較大，而且近從幾年來全國各地經(jīng)常發(fā)生內(nèi)澇的情況考慮，為了城市的長(zhǎng)足發(fā)展，和居民的生活質(zhì)量，該設(shè)計(jì)采用完全分流制排水系統(tǒng)。1.2排水方案論證本次設(shè)計(jì)取設(shè)計(jì)范圍內(nèi)的地形為南高北地，地形整體由南坡向北邊，但地形高差不大，坡度較緩。1.2.1污水方案論證方案一：方案二：兩個(gè)污水布置方案中，污水處理廠的位置是相同的，均位于設(shè)計(jì)高程較低的地方。由于城區(qū)有一條較大的河流穿城而過，因此污水過河的方式是決定兩個(gè)方案優(yōu)劣的關(guān)鍵。由于污水處理廠布置在河道南側(cè)，因此北側(cè)污水需要過河至南側(cè)。在方案一中，河道北側(cè)污水統(tǒng)一匯流至一點(diǎn)后集中過河，因此只需要在河道一處加大投資施工即可。而在方案二中，污水在兩處均存在過河，這在一定程度上增加了投資與施工難度，而且污水過河需要設(shè)置倒虹吸，過河的地點(diǎn)越多，對(duì)后期的運(yùn)行維護(hù)就提出了更高的要求，倒虹吸若不能較好的維護(hù)，極易造成污水管道堵塞。因此綜合考慮，本次設(shè)計(jì)選擇方案一。1.2.2雨水方案論證由于設(shè)計(jì)區(qū)域內(nèi)河道眾多，水系發(fā)達(dá)。因此雨水管道的設(shè)計(jì)采用就近排入附近水體的方案。這樣做的好處是一方面可以降低下游管道的匯流面積，減小管徑，另一方面是可以減少管道敷設(shè)長(zhǎng)度，降低埋深。由于河道南側(cè)城區(qū)存在眾多支流水系，因此遵循雨水管道不過河的原則，遇見河道即設(shè)置排出口。由于河道北側(cè)城區(qū)無支流水系，因此河道北側(cè)城區(qū)的雨水統(tǒng)一匯流至一點(diǎn)后集中排放至主河道。1.3推薦方案工程設(shè)計(jì)1.3.1設(shè)計(jì)參數(shù)選取及依據(jù)1.3.2污水設(shè)計(jì)參數(shù)老城區(qū)街坊面積總計(jì)550ha，人口密度300人/ha設(shè)計(jì)總?cè)丝跒?50×300=165000人新區(qū)街坊面積總計(jì)120ha，人口密度260人/ha設(shè)計(jì)總?cè)丝跒?20×260=31200人綜合生活用水定額為200，排放系數(shù)為0.8取平均日綜合生活污水定額為200×0.8=160L/(人·d)則平均日綜合生活污水量為：160×（165000+31200）=31392m3/d=363L/s。綜合變化系數(shù)Kz=2.7則最高日最高時(shí)綜合生活污水量為1.41×363=512L/s工業(yè)污水量：2500×0.8==2000m3/d=23L/s城市最高日最高時(shí)污水總設(shè)計(jì)流量為：23+512=535L/s2.3.3雨水設(shè)計(jì)參數(shù)暴雨強(qiáng)度公式為：q=t=t1+t2重現(xiàn)期P取2年t1——地面集流時(shí)間，取15mint2——管內(nèi)流行時(shí)間雨水設(shè)計(jì)流量：Q=φFqφ——綜合徑流系數(shù)，取0.651.4污水管道設(shè)計(jì)1.4.1污水管道設(shè)計(jì)規(guī)定（1）最大設(shè)計(jì)充滿度的規(guī)定：表2.1管徑與最大充滿度的關(guān)系管徑D（mm）最大設(shè)計(jì)充滿度h/D200~3000．55350~4500．65500~9000．70≥10000．75(2)最小坡度：管徑300mm的最小設(shè)計(jì)坡度3‰。(3)設(shè)計(jì)流速：最小設(shè)計(jì)流速是保證管道內(nèi)不致發(fā)生淤積的流速。污水管道最小流速定為0.6m/s.金屬管道的最大設(shè)計(jì)流速為10m/s，非金屬管道的最大設(shè)計(jì)流速為5m/s.。(4)最小管徑：1)廠區(qū)內(nèi)的工業(yè)廢水管、生活污水管、街坊內(nèi)的生活污水管200mm。2)城市街道下的生活污水管300mm。(5)覆土：1)冰凍要求：在0.70m以下。2)最大覆土：不宜大于6m。3)理想覆土：在滿足各方面要求的前提下，爭(zhēng)取維持在1~2m。4)荷載要求：最小覆土在車行道下一般不小于0.7m。(6)連接：1)管道在檢查井內(nèi)連接。2)管道管徑相同時(shí)的連接方式用水面平接，管徑不同時(shí)用管頂平接。3)在任何情況下進(jìn)水管底不得低于出水管底，若出現(xiàn)三條管段連接的情況，選擇出水管管內(nèi)底標(biāo)高低的一條管段連接。(7)坡度驟變的處理：1)管道坡度驟然變陡，可由大管徑變小管徑。2)當(dāng)D=200~300mm時(shí)，只能按生產(chǎn)規(guī)格減小一級(jí)。3)當(dāng)D≥400mm時(shí)，應(yīng)根據(jù)水力計(jì)算確定，但減小不能超過二級(jí)。4)管道坡度驟然變緩，應(yīng)逐漸過渡。(8)小管核算：1)當(dāng)有公建筑物位于管線始端時(shí)，應(yīng)加入該集中流量進(jìn)行滿流核。2)流量很小而地形又較平坦的上游支線，可采用非計(jì)算管段，采用最小管徑，按最小坡度控制。(9)溢流：污水管道在進(jìn)入泵站或處理廠前，當(dāng)條件允許時(shí)，可設(shè)事故溢流口，但必須取得當(dāng)?shù)赜嘘P(guān)部門的同意。(10)在充滿度過高的管段、跌水井、大濃度污水接入的井位以及污水管線上每隔500m左右的井位處宜設(shè)通風(fēng)管。1.4.2水力計(jì)算污水管網(wǎng)水力計(jì)算，是從上游起端節(jié)點(diǎn)開始向下游節(jié)點(diǎn)進(jìn)行，依次對(duì)各管段進(jìn)行設(shè)計(jì)計(jì)算，知道末端節(jié)點(diǎn)。為了確定各管段管徑、埋深、坡度、和充滿度等，必須先計(jì)算出各管段設(shè)計(jì)流量。污水管段設(shè)計(jì)流量（L/s）的計(jì)算公式：q=式中q1i各管段輸送的居民生活污水平均日流量(L/s)，它們?cè)诠芫W(wǎng)中滿足連續(xù)性條件；q2i各管段輸送的工業(yè)廢水設(shè)計(jì)流量（L/s），它們?cè)诠芫W(wǎng)中滿足連續(xù)性條件；q3i各管段輸送的工業(yè)企業(yè)生活與淋浴污水設(shè)計(jì)流量設(shè)計(jì)流量（L/s），它們?cè)诠芫W(wǎng)中滿足連續(xù)性條件；q4i各管段輸送的公共建筑生活設(shè)計(jì)流量（L/s），它們?cè)诠芫W(wǎng)中滿足連續(xù)性條件；Kz1i各管段輸送的居民生活污水量總變化系數(shù)；M污水管網(wǎng)中的管段總數(shù)。在確定設(shè)計(jì)流量后，便可以從上游管段開始依次進(jìn)行各設(shè)計(jì)管段的水力計(jì)算。污水管道水力計(jì)算公式為：V=其中：V——流速（m/s），確保排水管最小流速滿足規(guī)范規(guī)定R——水力半徑（m）I——水力坡降n——管道粗糙系數(shù)，HDPE管采用0.01，鋼筋砼管采用0.013計(jì)算結(jié)果詳見附件污水主干管水力計(jì)算表。污水設(shè)計(jì)流量計(jì)算表管段編號(hào)管長(zhǎng)(m)人口?指標(biāo)設(shè)計(jì)流量(l/s)本段平均流量(l/s)本段集中流量(l/s)轉(zhuǎn)輸平均流量(l/s)轉(zhuǎn)輸集中流量(l/s)總變化系數(shù)KzW7-W13335.89.7890002.1621.14W13-W12325.4009.78902.1621.14W12-W17179.45.537017.02201.9443.76W17-W162752.239030.99701.8561.49W16-W21133.95.033049.78301.7595.93W21-W30230.40072.9301.69123.25W30-W29135.90072.9301.69123.25W29-W395470093.621231.62174.67W39-W36647.43.8350127.184231.57228.7W36-W28583.64.3040221.566231.49359.55W28-W3149.62.1670270.801231.48426.99W31-W2770.73.9320346.482231.45531.1W55-W49567.512.8830002.0626.54W49-W41316.44.465012.88301.9834.35W41-W48299.519.302017.34701.8367.07W48-W3832210.859036.6501.7784.09W38-W44236.34.716047.50901.7691.92W44-W31715.67.953065.56101.69124.24W32-W23413.520.5310001.9640.24W23-W28338.49.782024.32901.8563.11W58-W56565.915.574000231.15W56-W52642.217.072015.57401.8660.72W52-W45392.521.652032.64601.7595.02W45-W36331.716.846073.70201.63147.59W43
