南樂縣水系圖5、地下水南樂縣可供開發(fā)的淺層地下水,主要分布在4.5m以下至40m以上的地層之間,靠降水入滲、河流側(cè)滲和灌溉回滲綜合補(bǔ)給。平均淺層水年儲量8723萬m3。豐水年可利用量8409.4萬m3,枯水年可利用量3846萬m3。根據(jù)地下水貯量及水8、文地質(zhì)情況,境內(nèi)分為貧水區(qū)、富水區(qū)、中等水區(qū)和咸水區(qū)。貧水區(qū) 含水層厚度在15m以下,面積219.8km2,占全縣總面積的36.4%。主要有兩處:一是縣西咸水區(qū),自元村鎮(zhèn)操守村起,沿衛(wèi)河兩岸,東北向,以梁村鄉(xiāng)的宋莊、邵莊至孫村,長10公里,寬300至500m,面積5萬畝;二是縣東貧水區(qū),自韓張鎮(zhèn)的陳莊起,沿陸塔河故道,東北向,經(jīng)韓張伸至福堪鄉(xiāng)的南漢村、牛村一帶,長8公里,寬200至400m,面積3萬畝。富水區(qū) 含沙層厚度在20米以上,面積35.4平方公里,占全縣總面積的5.9%。主要分布在千口鄉(xiāng)的東半部和張果屯鄉(xiāng)南部的部分地區(qū)。中等水區(qū) 含沙層厚度在10至20米之間,面積348平方公里,占全縣9、總面積的57.7%,分布在除貧水區(qū)、富水區(qū)以外的其它地區(qū)。咸水區(qū) 境內(nèi)咸水區(qū)有二:一為潴龍河咸水區(qū),沿潴龍河?xùn)|南西北走向,包括楊村鄉(xiāng)的西半部,城關(guān)鎮(zhèn)的東南部,谷金樓鄉(xiāng)的南部和韓張鎮(zhèn)西部的個別村莊。該區(qū)地下水礦物度在1.0至6克之間,平均在2克以上(每升大于2克為咸水,硬度大于250mg/L為極硬水)。二是縣西咸水區(qū),沿衛(wèi)河西岸,南起梁村鄉(xiāng)千佛村,北至西崇疃,西南東北向,略呈帶狀,面積2萬畝。經(jīng)調(diào)查,本項(xiàng)目廠址位于中等水區(qū)。地下水流大致方向?yàn)橛晌髂舷驏|北。6、土壤和植被南樂縣土壤共劃分為2個土類,3個亞類,8個土屬,24個土種。其中2個土類是潮土、風(fēng)沙土;3個亞類是黃潮土、褐化潮土、沖積性風(fēng)沙土10、。潮土類面積79.4萬畝,占全縣總土壤面積的97.5%,遍布全縣各鄉(xiāng)鎮(zhèn)。風(fēng)沙土類面積2.06萬畝,占全縣總土壤面積的2.5%。風(fēng)沙土土類只有一個亞類,3個土屬。南樂縣土質(zhì)較為肥沃,絕大部分適宜五谷百草及各種樹木生長。南樂縣屬暖溫帶落葉林帶,由于耕作歷史悠久,原有的自然植被已不復(fù)存在,主要是人工植被和野雜草。南樂縣生長的植物為:人工種植的木本、草本植物;農(nóng)作物;野生雜草。7、 社會環(huán)境概況7.1 行政規(guī)劃及人口南樂縣下設(shè)有12個鄉(xiāng)(鎮(zhèn)),鄉(xiāng)鎮(zhèn)以下設(shè)行政村、村民小組。全縣計有行政村321個,自然村403個,村民小組2587個。根據(jù)調(diào)查統(tǒng)計,全縣常住人口為50萬人。7.2 社會經(jīng)濟(jì)2009年,南樂縣11、國民生產(chǎn)總值75億元,年均增長17.2%,人均生產(chǎn)總值35.6元,年均增長16.7%,全縣社會固定資產(chǎn)投資49億元,年均增長35.6%;三次產(chǎn)業(yè)結(jié)構(gòu)比例為24.3:54.9:20.8;糧食總產(chǎn)42.89萬噸;畜牧業(yè)占農(nóng)業(yè)總產(chǎn)值的比重達(dá)到48.5%,綜合位次居全省第10位,為河南省畜牧強(qiáng)縣、全國秸稈養(yǎng)牛示范縣。近年來,南樂縣工業(yè)經(jīng)濟(jì)擴(kuò)張迅猛,運(yùn)行質(zhì)量和效益明顯提升,規(guī)模以上工業(yè)企業(yè)達(dá)到89家,實(shí)現(xiàn)增加值28.7億元,增長22.3%。建成了宏業(yè)化工、津華建材、大樂面粉、福鑫肉業(yè)等一批骨干企業(yè)。7.3 工業(yè)南樂縣擁有國有、集體及個體工業(yè)企業(yè),主要產(chǎn)品有軸承、雙氧水、汽缸體、白酒、布鞋、線毯、棉布、毛12、巾、磚、瓦、水泥等。工業(yè)生產(chǎn)主要包括冶金、煤炭、電力、機(jī)械、建筑、化工、釀酒、糧、油及食品加工、輕紡、造紙、印刷等。南樂縣手工業(yè)歷史久遠(yuǎn),品類繁多,但是受小農(nóng)經(jīng)濟(jì)制約,規(guī)模小,從業(yè)人數(shù)有限,但小而全,對保障南樂人民生產(chǎn)、生活必需品的供應(yīng),刺激國民經(jīng)濟(jì)發(fā)展起到了積極作用,并為南樂工業(yè)體系的建立健全打下了基礎(chǔ)。南樂縣的鄉(xiāng)鎮(zhèn)企業(yè)的主要經(jīng)營行業(yè)為草制品加工業(yè)、磚瓦窯業(yè)、面粉加工業(yè)。7.4 農(nóng)業(yè)南樂縣是典型的農(nóng)業(yè)縣。隨著農(nóng)業(yè)生產(chǎn)的發(fā)展,與農(nóng)業(yè)生產(chǎn)密切相關(guān)的畜牧業(yè)、林業(yè)、副業(yè)生產(chǎn)均有較大幅度增大。土地總面積624km2,合93.5萬畝。農(nóng)作物主要為適于大水大肥的優(yōu)質(zhì)、高產(chǎn)作物。主要農(nóng)作物結(jié)構(gòu):夏熟作物以小13、麥為主;秋熟作物有玉米、谷子、紅薯、高梁及豆類。經(jīng)濟(jì)作物中的夏熟作物以油菜為主;秋熟作物有棉花、花生及芝麻等。蔬菜以大白菜、蘿卜為主。7.5 交通南樂縣交通事業(yè)歷史悠久,發(fā)展迅速。106國道南樂區(qū)段,北起河北省界,經(jīng)由喬崇疃、五花營、南樂城關(guān)鎮(zhèn)、南清店等地,南至清豐縣界,全長21.2公里。安濟(jì)公路南樂區(qū)段西起河北省魏縣界,經(jīng)由元村、南樂城關(guān)鎮(zhèn)、韓張、大清、東至山東省莘縣界,全長39.8公里。項(xiàng)目廠址西廠界緊鄰106國道,交通便利。7.6 文物古跡及名勝南樂縣歷史悠久,留下了豐富的古代文化遺物和遺跡,各個時代的流散文物遍布全縣,被人們視為珍寶,并妥為收藏。南樂縣的歷史文物主要有戰(zhàn)國陶器、東漢盤龍14、石硯、東漢錯金銀銅帶鉤、東漢黃釉陶倉樓、東漢銅鐵合鑄博山爐、東漢畫像石、北朝青釉雞首壺、北朝三釉二系瓷罐、唐代墓志銘、北宋買地券、明金額畫像、金頡廟明代石刻、明代墓志銘、明代畫像。近、現(xiàn)代文物主要有烈士墓革命文物和革命遺址。南樂縣主要古跡有:古遺址、遺跡,古建筑、古墓葬等。南樂縣名勝主要有唐槐八株、繁水荷花、方山夕照、傅潭秋月、演教晨鐘、黃河晴波、翠香古亭、夢山三峰、古塔聯(lián)崗、桑泉等。據(jù)調(diào)查,目前,廠址區(qū)域500m范圍內(nèi)尚未發(fā)現(xiàn)地表文物。8、 南樂縣“十一五”環(huán)保規(guī)劃以城市總體規(guī)劃為指導(dǎo),逐步完善城市功能區(qū),有效解決城市臟、亂、差現(xiàn)象。加快城市污水處理廠和垃圾無害化處理廠的建設(shè),繼續(xù)加大對馬頰15、河飲用水補(bǔ)充源地的保護(hù)力度,實(shí)施綜合整治,確保縣城飲用水的安全。2008年底建成南樂縣污水處理廠,2009年建成南樂縣垃圾處理廠,目前均已投入運(yùn)行。完善城鎮(zhèn)污水管網(wǎng)、垃圾中轉(zhuǎn)站等基礎(chǔ)設(shè)施,實(shí)施雨污分流。2010年城鎮(zhèn)污水處理率達(dá)到45%。評價范圍內(nèi)的地表水體馬頰河南樂水文站為國控斷面,規(guī)劃為IV類水體,到2010年責(zé)任目標(biāo)為COD30mg/L,NH3-N 8mg/L。四、方案選擇1、農(nóng)村污水處理模式比較農(nóng)村污水未經(jīng)處理排入附近溝渠,污水中含有大量懸浮固體、有機(jī)物、難降解有機(jī)物、氮和磷的化合物、不可沉淀的固體顆粒、致病微生物以及無機(jī)鹽等污染物質(zhì)。含有這些污染物質(zhì)的處理水,如排放河流等緩流水體會導(dǎo)16、致水體的富營養(yǎng)化;排放具有較高經(jīng)濟(jì)價值的水體會使水體遭到破壞。為還馬頰河流域一個“水清、流暢、岸綠、景美”人類生活環(huán)境,需要對馬頰河流域農(nóng)村生活污水進(jìn)行處理,回用與農(nóng)田灌溉用水。確定農(nóng)村污水的處理程度是比較復(fù)雜的,要考慮的因素很多,主要有受納水體的功能、水環(huán)境質(zhì)量要求,污染狀況與自凈能力,以及處理后的污水是否回用等影響因素。根據(jù)水體自凈能力來確定污水處理程度時,既要考慮利用水體的自凈容量,又要防止水體的生態(tài)平衡遭到破壞,同時,還要全面考慮水系流域污染物防治規(guī)劃和區(qū)域的總體規(guī)劃等。深度處理技術(shù)包括物化法、生物法及生態(tài)法,處理單元技術(shù)有:混凝(化學(xué)除磷)、過濾、活性炭吸附、膜分離技術(shù)、臭氧氧化、曝17、氣生物濾池及人工濕地、人工浮島等。根據(jù)上述污水處理工藝的介紹,各種方法有著各自的優(yōu)勢,但也存在各自的局限性,如混凝法需消耗大量的藥劑,相應(yīng)的污泥量也較大;活性炭吸附法的吸附劑價格昂貴,再生困難;膜分離法雖然在國外得到廣泛應(yīng)用,但我國造紙中的非木材原料比重較高,以目前的經(jīng)濟(jì)實(shí)力難以進(jìn)行普遍推廣應(yīng)用;人工濕地技術(shù)的應(yīng)用受土地資源的限制,具有一定局限性。傳統(tǒng)深度處理工藝與人工濕地處理工藝進(jìn)行比較見表4-1。本項(xiàng)目的可利用用地范圍較大,有農(nóng)田及村莊周邊坑塘可供利用,不需要進(jìn)行征地及拆遷,彌補(bǔ)了濕地工藝占地面積大的缺點(diǎn),因此可選用潛流人工濕地處理技術(shù)作為深度處理工藝。表4-1
