26第一章概述1.1工程概述赤溪鎮(zhèn)污水處理廠（近期）工程配套管網(wǎng)服務(wù)范圍為赤溪鎮(zhèn)城區(qū)，2021年赤溪鎮(zhèn)人口約為2.3萬人，建筑總用地約為82.62hm2。近期污水處理規(guī)模為5300m3/d，尾水排入赤溪感潮段。赤溪鎮(zhèn)污水處理廠工程近期征地總面積約1.08hm2（10800m21.2設(shè)計(jì)目的通過污水廠對污廢水的處理，可以達(dá)到令污水和污泥減量化和無害化的目的，保護(hù)水資源。除此之外，通過結(jié)合實(shí)際課題與設(shè)計(jì)相結(jié)合，可以使學(xué)生更好的通過實(shí)踐通匯貫通課上所學(xué)知識，加深對污水生物處理工藝的理解。1.4地形勘察及自然條件1.4.1地形勘察赤溪鎮(zhèn)屬沿海丘陵區(qū)，群山環(huán)繞，屬于東南沿海丘陵山地區(qū)。1.4.2水文條件赤溪鎮(zhèn)赤溪河下游河段土質(zhì)較好，有良好工程地質(zhì)條件。有良好排水條件，常年水位89.9m，最高水位91.1m，河床底高88.0m，地面標(biāo)高93.0m。1.4.3氣候赤溪鎮(zhèn)鎮(zhèn)屬亞熱帶海洋性季風(fēng)濕潤性氣候區(qū)，全年氣候溫和濕潤，雨量充足。夏季為東南風(fēng)，冬季為西北風(fēng)。年平均氣溫18.2℃，年平均降水量1670mm。1.4.4水系赤溪鎮(zhèn)赤溪河從赤溪鎮(zhèn)東北部流向西南部，穿過赤溪鎮(zhèn)中部中心區(qū)域。1.5水質(zhì)概述1.5.1進(jìn)水水質(zhì)分析本次污水廠的污水處理流量為5300m3/d，根據(jù)已有的資料其進(jìn)出水水質(zhì)如下：表1-1城市污水水質(zhì)表指標(biāo)CODCrBOD5SSTNNH3－N有機(jī)氮TP有機(jī)磷無機(jī)磷數(shù)值3201601503526104321.5.2出水水質(zhì)分析本次赤溪鎮(zhèn)污水處理廠排放標(biāo)準(zhǔn)執(zhí)行《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》（GB18918-2002）中一級B排放標(biāo)準(zhǔn)。具體指標(biāo)如下：表1-2出水水質(zhì)標(biāo)準(zhǔn)指標(biāo)CODCrBOD5SSTNNH3－NTP大腸桿菌數(shù)（個(gè)/L）數(shù)值6020201581.5104第二章污水管網(wǎng)工程設(shè)計(jì)計(jì)算2.1排水管網(wǎng)系統(tǒng)體制比較與確定排水系統(tǒng)主要有合流制和分流制兩種。2.1.1合流制排水系統(tǒng)把生活污水、工業(yè)排放的廢水和雨水收集到同一管道系統(tǒng)內(nèi)集中排放的排水系統(tǒng)稱為合流制排水系統(tǒng)。根據(jù)污水匯集后的處理方式不同，又可將合流制分為直排式、截流式和完全合流制。（1）直排式合流制：管道系統(tǒng)的布置就近坡向水體，直接將收集的混合污水排入水體。在許多老城市的舊城區(qū)還大多采用這種排水體制。這往往因?yàn)檫^去我國工業(yè)不發(fā)達(dá)，城市人口不多，工業(yè)污水和生活污水量不大，水體的自凈能力還能滿足所接受的污水，因此水體污染問題還不是很明顯。但是隨著現(xiàn)代化城鎮(zhèn)和工業(yè)企業(yè)的快速發(fā)展，人們生活水平不斷提高，污水量增多，這種直排式合流制已經(jīng)不適合作為當(dāng)下城市的排水系統(tǒng)。（2）截流式合流制：對于現(xiàn)有老城區(qū)或舊城區(qū)的直排式合流制通常采用截流式合流制，在直排式合流制的基礎(chǔ)上進(jìn)行改進(jìn)。截流式合流制在對已有的舊城區(qū)排水系統(tǒng)改造中比較簡單，且投資相較較少，同時(shí)能大量降低污染物質(zhì)的排放，因此經(jīng)常采用。雖然比直排式有了較大改進(jìn)，但仍然存在不足，在雨天還是會(huì)有一部分的雨水與污水混流直接排放。（3）完全合流制：把生活污水、工業(yè)排放的廢水和雨水全部收集到同一管道，然后送往污水廠進(jìn)行處理。這種排水體制衛(wèi)生條件好，對保護(hù)城市水環(huán)境非常有利，但是工程量相比較大，初期投資大，同時(shí)對污水廠的運(yùn)行管理和處理工藝要求較高。2.1.2分流制排水系統(tǒng)分流制排水系統(tǒng)是把生活污水、工業(yè)排放的廢水和雨水分別收集在不同的管道系統(tǒng)內(nèi)排放的排水系統(tǒng)。其中又可以把分流制排水系統(tǒng)分為完全分流制和不完全分流制。完全分流制：既有污水管道，又有雨水管道。生活污水和工業(yè)排放的廢水通過污水管網(wǎng)收集輸送至污水處理廠。雨水則通過雨水管網(wǎng)收集后直接排入附件地勢較低的水體。這種排水系統(tǒng)有利于環(huán)境的保護(hù)，但是投資較大。不完全分流制：不完全分流制與完全分流制相比只有污水排水系統(tǒng)，雨水沿天然地面從地勢較高流向地勢較低的河流。對于城市短期建設(shè)來說能節(jié)省投資。但是不利于城市的長期的發(fā)展，因此待城市進(jìn)一步發(fā)展后仍要修建雨水排水系統(tǒng)，進(jìn)行分期建設(shè)。2.1.3選擇排水系統(tǒng)對于赤溪鎮(zhèn)整體規(guī)劃來看，合流制排水系統(tǒng)只有一條管道系統(tǒng)，施工方便，但對于赤溪鎮(zhèn)的長期發(fā)展和環(huán)境保護(hù)方面來說是不利的。分流制管線較多，對地下管線綜合設(shè)計(jì)要求較高，而且施工相對復(fù)雜，但適應(yīng)赤溪鎮(zhèn)和社會(huì)的長期發(fā)展。同時(shí)衛(wèi)生條件好，有利于環(huán)境保護(hù)，滿足居民對高質(zhì)量生活用水和生活環(huán)境的需求。是符合當(dāng)下社會(huì)發(fā)展的需要。從投資方面看，合流制排水管道的造價(jià)比完全分流制一般要低，但是合流制建設(shè)泵站和污水廠費(fèi)用卻比分流制要高得多。對于赤溪鎮(zhèn)來說，城鎮(zhèn)服務(wù)面積相對來說較小，長期居住人口通過調(diào)查約為2.3萬人，因此可以選擇分流制排水系統(tǒng)。綜合上述比對，因此根據(jù)赤溪鎮(zhèn)的地形特點(diǎn)、水文條件等現(xiàn)有的情況綜合考慮確定本次設(shè)計(jì)選用分流制排水系統(tǒng)。2.2污水廠廠址選擇要求根據(jù)《室外排水設(shè)計(jì)規(guī)范（2016版）》（GB50014-2006）中污水廠位置的選擇一般注意事項(xiàng)，污水廠位置的選擇應(yīng)滿足下列要求，在城鎮(zhèn)水體的下游。便于處理后出水回用和安全排放。便于污泥集中處理和處置。在城鎮(zhèn)夏季主導(dǎo)風(fēng)向的下風(fēng)側(cè)。有良好的工程地質(zhì)條件。少拆遷，少占地，根據(jù)環(huán)境評價(jià)要求，有一定的衛(wèi)生防護(hù)距離。有擴(kuò)建的可能。廠區(qū)地形不應(yīng)受洪澇災(zāi)害的影響，防洪標(biāo)準(zhǔn)不應(yīng)低于城鎮(zhèn)防洪標(biāo)準(zhǔn)，有良好的排水條件。有方便的交通、運(yùn)輸和水電條件。因此，根據(jù)以上條件，赤溪鎮(zhèn)污水廠廠址選擇在位于赤溪水源下游段。2.3尾水排放口根據(jù)赤溪鎮(zhèn)地形并且結(jié)合水文資料：污水處理廠廠址位于赤溪下游河段，廠區(qū)附近有一條水渠直通赤溪河下游，在水渠中進(jìn)行初步自凈，進(jìn)入赤溪河后水域面寬，易于稀釋擴(kuò)散。2.4污水量計(jì)算2.4.1城鎮(zhèn)用水水量量預(yù)測根據(jù)《城市給水工程規(guī)劃規(guī)范》（GB50282-2016）中對城市最高日用水量的計(jì)算規(guī)定中，選擇不同類別用地用水量指標(biāo)法計(jì)算城市用水量。表2-1不同類別用地用水量指標(biāo)qi[m3/(hm2·d)]類別名稱用水量指標(biāo)居住用地50～130綠地與廣場用地10～30工業(yè)用地30～150商業(yè)用地50～200文化設(shè)施用地50～100行政辦公用地50～100醫(yī)療衛(wèi)生用地70～130城市最高日用水量計(jì)算：Q=式中：qi??不同類別用地用水量指標(biāo)ai??不同類別用地規(guī)模2.4.2城鎮(zhèn)最高日用水量量計(jì)算根據(jù)上面的城鎮(zhèn)用水量計(jì)算公式與本次赤溪鎮(zhèn)不同類別用地面積計(jì)算本次赤溪鎮(zhèn)的城鎮(zhèn)用水量。表2-2赤溪鎮(zhèn)最高日用水量計(jì)算表用地類別名稱用地面積（hm2）用水指標(biāo)qi[m3/(hm2·d)]最高日用水量（m3/d）居住用地26.581203189.6文化設(shè)施用地111001100綠地與廣場用地7.2530217.5工業(yè)用地13.791502064商業(yè)用地4.5200900行政辦公用地6.5100650醫(yī)療衛(wèi)生用地131301690合計(jì)9811.1遠(yuǎn)期居住用地401204800遠(yuǎn)期合計(jì)11421.5根據(jù)計(jì)算得到赤溪鎮(zhèn)最高日用水量近期為為9811.1(m3/d)，向上取整10000(m3/d)，為116(L/s)；遠(yuǎn)期為11421.5(m3/d)，向上取整12000(m3/d)，為140(L/s)。2.4.3污水廠污水量計(jì)算結(jié)果進(jìn)廠污水量=（最高日城市用水量/￡）×ξ×η×（1＋α）式中：￡：用水量高峰系數(shù)，即為用水日變化系數(shù)根據(jù)《室外給水設(shè)計(jì)規(guī)范》GB50013-2006(2016版)最高日城市綜合用水的日變化系數(shù)為1.1～1.6，本工程設(shè)計(jì)近期取1.5，遠(yuǎn)期取1.3。ξ：排放系數(shù)，隨著節(jié)水工作的推廣，該指標(biāo)將會(huì)逐漸降低，根據(jù)《城市排水工程規(guī)劃規(guī)范》(GB50318-2000)并且結(jié)合赤溪鎮(zhèn)的給排水設(shè)施水平和供水管網(wǎng)漏損等因素確定近遠(yuǎn)期為0.9。η：污水收集率，反映實(shí)際收集污水量的程度，隨著排水系統(tǒng)的不斷完善，收集率逐步提高，近期確定為80%，遠(yuǎn)期為95%。α：地下水滲入率，在地下水位較高地區(qū)應(yīng)考慮地下水滲入量。地下水滲入率反映了排水管道接口可能不嚴(yán)密，使地下水滲入排水管內(nèi)或出現(xiàn)雨、污水混接，導(dǎo)致排水量增加，據(jù)有關(guān)資料，該系數(shù)約10～30%，本設(shè)計(jì)近、遠(yuǎn)期均取10%。近期污水=（10000/1.5）×0.9×0.8×（1＋1）=5300m3/d=62L/s遠(yuǎn)期污水=（12000/1.3）×0.9×0.95×（1＋1）=7300m3/d=85L/s因此計(jì)算出近期污水廠污水處理規(guī)模為5300m3/d，遠(yuǎn)期污水廠污水處理規(guī)模7
