In many ways it looked like Vientiane and Ho Chi Minh City。另一方面對(duì)于塑料埋地排水管的研究試驗(yàn)和標(biāo)準(zhǔn)及規(guī)范制定工作也逐步有了進(jìn)展,部分地區(qū)已開始大量應(yīng)用?建設(shè)部專門組織的兩個(gè)推廣會(huì)上,上海?北京等市政部門都介紹了使用塑料埋地排水管的成功經(jīng)驗(yàn)?目前有的塑料埋地排水管生產(chǎn)企業(yè)已經(jīng)出現(xiàn)供不應(yīng)求的形勢(shì)?塑料埋地排水管正成為新的投資熱點(diǎn)?二?市場(chǎng)潛力分析排水設(shè)備是現(xiàn)代化市政建設(shè)必不可少的重要基礎(chǔ)建設(shè),與發(fā)達(dá)國(guó)家相比,我國(guó)市政排水設(shè)施水平十分落后,我國(guó)正面臨全國(guó)大量投資建設(shè)排水管網(wǎng)的歷史機(jī)遇?中國(guó)是水資源嚴(yán)重短缺的國(guó)家,人均水量不足2400立方米,僅為世界人均水量的四分之一?在中國(guó)的很多城市和地區(qū)能否保證居民的供水已經(jīng)成為面臨的首要難題,全國(guó)668個(gè)城市中有400多個(gè)供水不足?造成水危機(jī)的重要原因是水資源被沒有控制?沒有處理的排水所污染,例如,中國(guó)七大河流流經(jīng)的15個(gè)主要大城市河段中,有13個(gè)河段水質(zhì)污染嚴(yán)重?水污染還直接危害到經(jīng)濟(jì)?生活和人民健康的各方面?現(xiàn)在,全國(guó)上下都在呼吁保護(hù)水資源,治理水污染?在這樣的形勢(shì)下,排水設(shè)施工程已經(jīng)成為各地基礎(chǔ)建設(shè)的熱點(diǎn),在排水設(shè)施工程中排管網(wǎng)是其核心部分?我國(guó)近年對(duì)城市排水設(shè)施的投資增長(zhǎng)很快,按1990年不變價(jià)計(jì)算,?%%?(和發(fā)達(dá)國(guó)家仍有很大的差距)?%%,反映了國(guó)家對(duì)于加快治理水污染的重視正在提高?據(jù)建設(shè)部統(tǒng)計(jì),隨后三年即98?99?2000年每年新建排水管網(wǎng)系統(tǒng)增長(zhǎng)率分別為10%?16%?22%,呈遞增趨勢(shì),且遠(yuǎn)遠(yuǎn)高出國(guó)民經(jīng)濟(jì)增長(zhǎng)的總體水平?若按每年20%的增長(zhǎng)率,則每年需排水管約150萬公里,若有50%使用雙壁波紋管則每年使用量為75萬公里,這不包括城市排污管網(wǎng)的改造及新建污水處理廠所帶來的市場(chǎng)需求?建設(shè)部專家預(yù)測(cè),在“十一五”期間我國(guó)在供水和排水方面的投資增長(zhǎng)率將繼續(xù)高于社會(huì)固定資產(chǎn)投資增長(zhǎng)率?在城市排水將投資1200億左右, 2005年污水的處理率接近40%,到2015年污水處理率超過60%?所以,我們預(yù)測(cè)在今后二十年內(nèi)我國(guó)將進(jìn)入建設(shè)排水管網(wǎng)的高潮,為塑料埋地排水管創(chuàng)造了空前的發(fā)展機(jī)遇?按照《國(guó)務(wù)院關(guān)于環(huán)保若干問題的決定》和建設(shè)部《關(guān)于城市污水集中處理行業(yè)發(fā)展和設(shè)備產(chǎn)業(yè)化工作的初步設(shè)想》,2000年 “三江三河”%時(shí),城市污水管網(wǎng)投資為129億元?2010年城市污水集中處理率達(dá)到50%時(shí),?其中至少將有40%?另外城市及工業(yè)污水處理是一個(gè)潛在的巨大市場(chǎng)?2001年7月北京市人大提出的北京市城市建設(shè)提案,共投資1800億元用于市政基本建設(shè),申奧成功后,又追加1000億元,其中200億元用于水?電?氣?暖,800億元用于污水處理?使污水處理達(dá)到90%,這兩項(xiàng)預(yù)算中有400億元用于管道采購,上海“十五”期間以計(jì)劃投資1500億元用于市政基礎(chǔ)建設(shè),其中400億元用作建設(shè)污水處理廠及排水管網(wǎng)建設(shè)?上海市?北京市率先淘汰水泥管?推廣使用塑料管,加之城市污水處理投資力度加大,必然帶動(dòng)全國(guó)各地城市掀起“管道革命”的熱潮,新型管道企業(yè)的不斷涌現(xiàn),生產(chǎn)能力不斷擴(kuò)張,建設(shè)部必將出臺(tái)政策法規(guī)在全國(guó)范圍內(nèi)禁止使用水泥管作為排水排污管道?市場(chǎng)對(duì)塑料排水?排污管道需求將急劇增大?如全國(guó)人口在50萬以上的城市全部使用塑料排水?排污管道,?HDPE雙壁波紋管生產(chǎn)設(shè)備及生產(chǎn)技術(shù)于九十年代初期發(fā)展成熟,目前在發(fā)達(dá)國(guó)家的諸多領(lǐng)域廣泛使用?尤其在美國(guó)?加拿大?日本?韓國(guó)及歐洲各國(guó),雙壁波紋管廣泛用于工農(nóng)業(yè)大型輸水?各種領(lǐng)域排水?排污?排氣等?我國(guó)近幾年來才開始引進(jìn)此類設(shè)備,且集中于大中型企業(yè),其原因是從國(guó)外購置此類設(shè)備價(jià)格昂貴,每套約400500萬美元,使中小型企業(yè)望而卻步,而大型企業(yè)在發(fā)展規(guī)模上也受資金限制,從而限制了雙壁波紋管的發(fā)展?江蘇欣榮科技發(fā)展有限公司通過引進(jìn)消化國(guó)外先進(jìn)技術(shù)并對(duì)國(guó)內(nèi)引進(jìn)設(shè)備進(jìn)行研究,對(duì)比各種結(jié)構(gòu)壁管的優(yōu)缺點(diǎn)推行HDPE擠出成型波紋管生產(chǎn)線,此生產(chǎn)線分600?800二種機(jī)型?范圍管徑從225~800mm,填補(bǔ)了國(guó)內(nèi)空白,設(shè)備價(jià)格為600—800萬元人民幣,是替代進(jìn)口設(shè)備的首選產(chǎn)品?三?制品規(guī)格?性能?特點(diǎn)于用途表2:HDPE雙壁波紋管材規(guī)格?尺寸?重量(kg)及售價(jià)(元)管材規(guī)格DN225DN300DN400DN500DN600DN700內(nèi)徑225300400500600700外徑260346460578697800單米重量131925原料成本7760萬 /噸標(biāo)準(zhǔn)長(zhǎng)度6000mm?9000mm?12000mm1噸管材的原材料包括:,。 可根據(jù)用戶的不同要求,設(shè)計(jì)不同波型和環(huán)剛度的成型模塊。 it was a wonderful journey of discovery. The largest dictionary in the world is the Oxford English Dictionary, or OED for short. The idea for this dictionary came from an important meeting in Britain in 1857. Twentytwo years later, Oxford University asked James Murray to be the editor of its new dictionary. I am fond of my sister but she has one serious shorting. She can be really stubborn. Although she didn39。 In the early evening we always stop to make put up our tent and then we eat. After supper Wang Wei put her head down on her pillow and went to sleep but I stayed awake. At midnight the sky became clearer and the stars grew brighter. It was so quiet. There was almost no wind—only the flames of our fire for pany. As I lay beneath the stars I thought about how far we had already travelled.A NIGHT THE EARTH DID’T SLEEPTwo days later we crossed the border into Vietnam. We began to see many more people,but I wasn’t surprised .I read in an atlas before our trip that Vietnam has almost seven times the population of Cambodia. We met a farmer who gave us directions and told us that he grows a new rice crop four times every year so he can feed more also told us that the northern part of his country has many mountains and it is much cooler than here in the south,where it is the flat delta made it easier for us to got warm very we drank lots of water and ate lots of the delta separated into nine smaller days later,after we had passed thousands of rice fields,we came to the sea. We were tired but also in high spirits:our dream to cycle along the Mekong River had finally e true.PART2 A NIGHT IN THE MOUNTAINSPART 1 THE DREAM AND THE PLAN10% 50HZ冷 卻 水:≤20℃ 壓縮空氣:≤八?項(xiàng)目投資情況及經(jīng)濟(jì)效益分析 投資情況項(xiàng)目總占地50畝,設(shè)計(jì)8條生線,總投資8000萬元,固定資產(chǎn)投資10000萬元,流動(dòng)資金6000萬元。 配有強(qiáng)力冷卻的波紋成型系統(tǒng),可保證連續(xù)生產(chǎn)時(shí)較高的生產(chǎn)速度?先進(jìn)的潤(rùn)滑系統(tǒng)使成型模塊的磨損降至最低,并具有長(zhǎng)久的使用壽命,確保運(yùn)行精度,保障管材的質(zhì)量穩(wěn)定。 Strange things were happening in the countriside of northest there days the water in the village wells rose and fell, rose and noticed that the well walls had deep cracks in them. A smelly gas came out of the cracks. In the farmeryards,the chickens and even the pigs were too nervous to ran out of the fields looking for places to jumped out of their bowls and about 3:00am on July 28,1976,some people saw bright lights in the sound of the planes could be heard outside the city,who thought little of these events,were asleep as usual that night. We will reach Dali in Yunnan Province soon, where our cousins Dao Wei and Yu Hang will join us. We can hardly wait to see them!t know the best way of getting to places, she insisted that she organize the trip properly. Now, I know that the proper way is always her way. I kept asking her, When are we leaving and whe
