城市面源污染特性及污染負荷預測模型

城市面源污染特性及污染負荷預測模型研究1葉閩楊國勝肖彩長江水資源保護科學研究所武漢430051摘要本文通過分析武漢市漢陽地區(qū)城市面源污染的來源和污染特征，并針對城市土地利用和下墊面類型特點，建立城市面源污染預測模型，研究探討城市降雨徑流及污染負荷預測模擬和遷移規(guī)律。所建模型已成功地應用于武漢市漢陽地區(qū)城市面源污染控制技術研究，獲得了滿意的結果。該模型可為城市水環(huán)境規(guī)劃、面源控制和管理研究提供科學手段。關鍵詞城市面源污染特性預測模型1前言隨著我國城市化水平的發(fā)展進程加快，可滲透地面的面積比例越來越小，由暴雨徑流產(chǎn)生的突發(fā)性的、沖擊性強的城市面源污染已成為受納水體水環(huán)境污染的主要來源之一。城市暴雨徑流中包含有大量的污染物，使得其初期徑流產(chǎn)生的污染負荷遠高于城市生活污水。因此，由面源引起的水環(huán)境污染已成為當前城市水環(huán)境綜合治理中亟待解決的主要問題之一。琴近潔十物年滲來狼，折武頸漢勵漢謙陽毛地幻區(qū)捏的盼城員市狐面執(zhí)源于污瘋染今加呀劇擾，幕大釘量膚污蓬染殃物捐排梅入憂水梳體斷，躍水岸質假急聚劇劑下子降功，范由灑城頃市神面矩源虧污酒染街和膠其思他進污摔染的引幼起碼的扶水紫環(huán)繡境鼻問念題箏已艘經(jīng)情嚴訓重棍制杯約長了犁城狗市半的夠可曬持水續(xù)質發(fā)脊展昏?？荼敬笪慕蛲ㄍ^揭分能析細武頂漢帽市平漢比陽葵地隸區(qū)窯城魯市競面壤源文污指染慰的裳種賭類費、歷來羊源錄和竿污幻染喝物夕特穗征泡；漠并堪針僻對借城拖市賺土毒地伶利端用談和嘉下枝墊嶺面殼類灰型催特似點爛，犧建云立惑城洲市遷面詢源倍污藍染討預麥測熄模知型鞭，犁研注究廟探下討壘城涼市燥降危雨錢徑占流杜及食污占染扭負雜荷鼠預懷測脂?？棓M參和敞遷領移劑規(guī)鋪律灘。抱為峰有鉗效種控潔制餃城香市趙面淡源匠污食染嗚提貿(mào)供款強抽有頓力抵的板科肅學破手垮段雖。扒2筑罰立漢茅陽腦地婆區(qū)返城靠市偽面殿源貿(mào)污息染堵來的源高及嫂特本性鑒武舉漢猾市啦漢誠陽奉地鍬區(qū)即位屆于講武住漢此市錯西置南葡部底，叮長瘦江因、漲漢霉江崇交絹匯希處誤的綠三雕角晴地改帶魄。怎為背武該漢枕三拖鎮(zhèn)爆一防方憲。線以己漢艦陽畝區(qū)因漢病陽潑大緞道慶和察鸚拖鵡芝大飼道深為懇軸平的睜建農(nóng)成濟區(qū)云，串兩嫂面其臨退江熱（鹽東闊北陪臨糠漢丑江循，務東養(yǎng)南映臨域長儲江館）悟，譽是批漢宋陽晶地秤區(qū)驅人碼口蛾密儉度抽最塵高泥的郊地師區(qū)甩，船人也口出密渴度昌為旗1勾.肆6堂萬瓶人裂/聽k諸m小2醬。剪漢尿陽節(jié)區(qū)別域遵內易水莫資孫源磚較口為邀豐核富虎，熊分布布藍著辰大區(qū)大墓小濃小姐的個湖楚泊辦數(shù)詳十嶺個蔬。案根殲據(jù)扒近精年蜂來菠湖公泊過水師質震監(jiān)糾測造結臺果砍分碌析亦，介漢理陽壟城戒區(qū)尸幾拒個血重腔點首湖掃泊咳水解質鑒極趙差元，刮按耽國冒家爪地未表資水烏環(huán)漲境豪質繪量蝴標沙準元評勸價架，繳基王本拖均錫為阻劣由V裂類翠。弦這距些陳湖躍水蹈污濟染般來鈴源失除姓受贊工劉業(yè)舟污包染罰廢守水隊、軟城綿市奪生剛活項污需水戰(zhàn)共澆同餅影家響記外皇，鎮(zhèn)來督源三于誘暴淘雨哲沖炮刷釘?shù)厥⒈黹l固詢體去污圈染郊物壽所適產(chǎn)殊生術的畜污再染番也竄不多容由忽槍視職。蠢特辰別柔是沿在股暴瞎雨械初拐期賤，衰由戰(zhàn)于援降辰雨漸徑笑流夕將濫地差表粥的顯、割沉封積休在不下賽水粱管笑網(wǎng)賭的艇污墊染敘物戰(zhàn)，抽在壁短坦時蟲間徹內晃，賺突役發(fā)宮性眉沖游刷敗匯瘡入派受餐納伸水瘦體旅，沙而堵引孩起燙水展體揀污采染脾。億據(jù)紡觀坑測兩，睛在頂暴露雨穗初忍期技（丈降屋雨流前江2纖0廢分再鐘狡）屠污覺染緣物蔬濃抄度溉一長般菠都趁超須過柄平拿時迅污勢水梅濃需度廚，樸如請弱2幻0逐0群3和年峽6宇月匆，餐對松漢方陽汗地川區(qū)判城碑市剖雨歸水渠排喇水撓出籌口纏處辣一慕次福大易暴悲雨閘監(jiān)立測閣，覆其連監(jiān)魚測河結學果質比盲平俱時較排淡放浪口得流增出頌的捷污泥水筒濃視度較要孤高均得境多不，庭如本S失S挎（鞭懸美浮膝物杠）屬濃儲度嗽值艘就庸高致于禽平堂時威污功水詞濃漲度脾的靠1瞎0躁倍憑左障右參，擁C元O圍D需高掙3踩～贈4霞倍勞，幼而愉且殃暴榜雨別期起入筍湖絹水撕量土遠逗遠富的死大赴于富平壟時讀排雹放工口須的尾水馳量療。柳因政此折，喘城咸市倆面碗源糊也勢是珍引黎起早水張體怕污篇染類的饞主耐要禿污觀染浴源販。槽對界于慧城園市駱面絨源哈污奪染癥具扣有掛突倆發(fā)磁性灘、震高黨流截量崇和蹈重瞇污蚊染勉等界特威點浪，株主偉要縫是泛因震為假城烘市學的夾硬調質撐下歸墊違面賺占漲大戴多萄數(shù)湖，奇徑買流匙系粱數(shù)碰較申大易，映因紀而聚形遼成譜徑俱流弦的元時胡間骨短貢，鴉地痛下省入牽滲站量好小釋，插對日污踏染脹物榨的溪沖傅刷客強權烈濱。炭另司外術，使由佩于圣城弦市忙的憂市筆政稿建持設糕和貝管致理窗不怠到喝位豆，箱城足市掘排篩水醒管來網(wǎng)棟以顯雨源污飽合紅流臉制灘居巴多法，巴生勻活撥垃攪圾妥及示廢終棄鏟物苦任之意晶丟勺棄牲，艱由沙人縱為寧因客素挖引忙起驅的竊面?zhèn)捶盼矍韭谜即慰倲偽厶先竞蛄扛斓膹?甚0眨％牽以鍵上肉。容使奇得掉這帆些姻污杜染贈物使除膚了主受浩地敢形證影腔響明在寬雨膽水蛾的美作腐用品下珍流積向深低桂洼谷地駱外糟，合大夜部原分史匯仍入唉了膜城溜市禮地梅下江排扔水令系置統(tǒng)框，私然籮后挎流兆入問湖倡泊穩(wěn)、謙河未流退中舞污屠染破其呀水暫體屢。材根欄據(jù)謀實莫地侮調涉查浮和矛遙斥感雜衛(wèi)揀星鴿資悟料像分娛析優(yōu)，水武識漢效市球漢誼陽脈城喊區(qū)凝，鎖主執(zhí)要需以曠工緒礦里企恒業(yè)屆、忍城堪市牢居腎民巷區(qū)蝶、僅機漲關紐單竿位齊的刺建得筑唐物閑群幣、且城狐市齒道各路旬（艙包淚括養(yǎng)?？疖嚰s場津、憲廣紗場糊等租）免不急透什水販硬察質疑下窯墊晝面股為豎主筐，陳硬舊質止下特墊米面奔占扇城蘆區(qū)找面版積彎8鳳0厚％劇左啄右殼，討其干他態(tài)為饒沿點湖值荒捆地拒、櫻菜障地擦、增小狂區(qū)牢公斑園碎、卻道準旁訴綠邊地深等酷一馳些矮透計水董地桃面州即炭軟耐質播下到墊愈面歡組從成武的告區(qū)梳域甚。晌下論墊辜面總的兔類芬型偏直千接踐決綁定露了哀面沸源開污柴染孤的則性責質鴨和運特酷征搶?？罱?jīng)翻過螞調詞查拒分談析應，仙漢抵陽碎城獸市公面擔源嶄有危如本下音一咳些徹特梯征賭：維（鐮1嘆）亞城猶市喇的備硬巡質度下鉆墊洋面塌占吳大瞧多踢數(shù)肝，羞徑盜流洗系闊數(shù)棒較厚大悄，寇形衰成王徑牢流屆的翁時撿間腰短修，塔地竄下煉入貌滲家量愈小詠，歷對狀污構染把物劫的徒?jīng)_谷刷唇強旅烈豈。圖徑漢流真形禮式炕以繡短宋時顆間深的衛(wèi)地餓表猾徑諒流客和添較溫長件時托間濕的臟管禮內席流悼為揀主涼。頌（培2好）扶城智市耗面以源狡－持雨時水并徑刊流異可含粗考分玻為塑屋西面發(fā)徑錯流坊和桌路厭面發(fā)徑裳流陵。哄屋覽面算徑終流兔污全染刮源西主鑒要少為磚屋育面痕沉賊積穴物愉及轎屋左面權材拒料站析罰出慧物證。雄最障關荷鍵私的麗因侮素您為宰屋特面竊材傘料似性叔質止。武路紐面言徑惰流密水撲質餡除控了手與梅路死面柳材句料攝、葛老洪化攻程旅度高有言關殃外眼，品還瓶取懂決艙于主道訪路嘆交援通局密助度診。蘿主鍬要嫌污淹染鵲源機為獲路起面私沉敵積允物濱、巡行掃人循和塘車桶輛責的是交沿通烤垃鴿圾殲等墳。豐屋梳面鍵徑兼流改和凳路煙面逮徑仁流諸兩坑者陶所漿受芳的澆污圣染反程賺度許不縮同雪。襪屋扇面勝徑滲流復基巨本錄不尺受閑人箱、誓車監(jiān)輛憲等顛流魚動呆因艙素重的挪影架響騎，匪因睛此留水振質虎略脫好族于炸路菌面氧徑脊流憤。脖（潤3鳴）咬面徹源仿負瘡荷伯來型源院主慰要亞為成：毛屋漸面刺建格筑農(nóng)材推料割、逼建率筑庭工舒地怒、史路番面呢垃挽圾揮和余城牲區(qū)終雨程水親口笑的勿垃磚圾繼和胖污拋水淋、均汽閑車喚產(chǎn)飾生憐的鋒污世染許物老、先大惡氣對的沖干吵濕免沉泳降撒等縮。劇在率這下些燙污游染損物疤中孩產(chǎn)粥生篩負測荷距影歐響近較影大躺為蹈雨雄水杜口皇的犬垃科圾包和荷污寧水半。擊雨震水羅口知的參污框染傘可藝分攪為爭三晚種壽：右人渡為廉掃赴入張、企丟援入芹的秀各料種世生恨活笑垃輛圾鐮（對紙懂屑掙、聚煙崖頭榆等纏道瀉路怪及警生吸活避固妙體端垃哭圾截）木、俊人哭為牲傾聲倒值的嚼污慢水之和宏腐潮爛丸變映質牧的暢沉將積性物傻等穴。雁（興4快）鍋地文表見徑領流撇大妖部殊分傳通錄過夕城想市威下厲水集管悅網(wǎng)遍排現(xiàn)入勺受甜納親水妙體陶中響，齡其躍匯路水貼區(qū)猾范彼圍踢主品要斑通棒過憤排若水藏管躍網(wǎng)透的陪走舅向代確掉定販。碑（艱5渴）燃城摩市產(chǎn)面杠源殼的派主點要溜污拐染替物怨為幸：礙有靈機諸物旬、捕S質S菌、園石棍油涉類賊和敬N杰、劃P陳等踩。貓3越帥短漢殘陽毛地拖區(qū)雀面丸源六污鍛染范模弓擬姜3啟.彩1創(chuàng)妹噸模在擬扎方敬法羞面互源秒污旅染粉是防造架成閣水狼體恰水包質活污丙染罷的貪重構要漠因甲素艘之奧一亞，蝕要貍控宅制離面帶源艷污抬染拖，型除腎加精強剛城移市違管坦理左力泉度曾，礙減壇少淹人罷為掃因胞素顏影斗響支外揀，倆根鉤據(jù)券面嘩源足污縫染擺源些特泰征嚇，虹研未究越城希市麗面請源鉛污信染共物腦的雀產(chǎn)滑生朋、咱運擠移正與貝輸乖出壁過謊程棚，貌開胸發(fā)印出速適陪合子漢語陽酒地窗區(qū)竄的開城障市微面奉源驢污狀染敬負醒荷訓與伴預寇測避模浪型憐。叼也仿是衫為廳更漠有悼效梅辯版識是影日響悲面質源反污兇染扶的煮各睡種帳關司鍵沃性臺因磁素費，濫分哄析膝城棕市示發(fā)昌展芽與街城您市山面畢源漿污愁染確的房關福系飄，芝有成針裝對垮性扯采棕取時一泰系牛列面技看術埋和晨措案施姨，偷削公減壽徑括流黑量雀，禽降狡低君污冒染萬物伙輸沃出敵濃困度兩，巖達猾到筒控蔬制剝面效源黨污讓染榴有博效鋼途鼠徑碌。伐由路于調面乏源慶污森染恩是晶由唱降呀雨貪徑善流鬼產(chǎn)滴生暴，纏其去污鐵染遙具佛有趨發(fā)斗生泳隨爭機威、舉來捉源謀和偶排響放課點排不坊固痰定健、若污遺染印負赤荷往的園時束空唱變虹化屋大仁、冊污蛋染仆途意徑診的自隨嫌機宣性今和葵多麥樣皆性劣、享監(jiān)價測嫂、屯控話制斜和瘦處霧理曬難桶度壤大黑等圖復裁雜遇特銷點策。游因值此部，罷對端其廊面哭源驚污溜染忽的債預們測香和擔模招擬啊存歪在糟著壯很勻大氏的襖難甩度設。吹國必際塊上負對惱面健源酸污章染陰的弓產(chǎn)后生木規(guī)洽律鐘和伶模僚型爽模釘擬述也律進虛行姻了慣大略量系研尊究揭。必基叉于書城繁市羊面蠻源粥污絨染壞物翅的寺產(chǎn)鍋生腦主爺要侄源街于仔降憐雨太徑延流敗沖紛刷孫地贏表察累斷積稱物委，鵝以拐及篩徑啟流妻挾帳帶付污司染飛物禮在莫排文水夢系攝統(tǒng)埋內圾的職運導移目，式在厲此敗基厲礎聞上起開莊發(fā)無出收大權量甲城樂市綠面罪源宣污潑染棵模甜型智。土其崖中沉，擠比米較自成熄功緊的松模股型胖有攔：節(jié)城午市很暴科雨截水坊管漢理逆模汁型軟（僻S征W賀M觀M狂）亭和浙城比市連暴申雨甚徑隆流杏模桃型積（戴S樣T冰O丹R陪M迷）蹈，挽化培學間物牧質這徑潔流捆負酒荷酬與仿流盞失豆模社型濱（練C揪R刺E蹈A角M樓S憑）叼。丸另賢外淺，棕在藝此峽之暖后額開蘿發(fā)懇的格M伸I這K螺E餐－秩S待W蜘M糧M秘模后型咸，出將病一季維病非臨恒樹定同流斷模奮型遼與足暴攤雨陶徑私流燃的棉分南布點式余模屯型徐結球合暖，袖模覺擬濫暴桿雨鉤水夠和傾廢默水健排
