At first, the government had great difficulty in persuading people to leave Rio and to settle in Brasilia. Since 1960, however, the population has been growing all the time. Brasilia has quickly established itself as the capital of the country. The idea to have the capital moved so far inland will have a great effect on the future of Brazil.A pilot noticed a balloon which seemed to be making for a Royal Air Force Station nearby. He informed the station at once, but no one there was able to explain the mystery. The officer in the control tower was very angry when he heard the news, because balloons can be a great danger to aircraft. He said that someone might by spying on the station and the pilot was ordered to keep track of the strange object. The pilot managed to circle the balloon for some time. He could make out three men in a basket under it and one of them was holding fieldglasses. When the balloon was over the station, the pilot saw one of the men taking photographs. Soon afterwards, the balloon began to descend and it landed near an airfield. The police were called in, but they could not arrest anyone, for the basket contained two Members of Parliament and the Commanding Officer of the station! As the Commanding Officer explained later, one half of the station did not know what the other half was doing ! It must have been about two in the morning when I returned home. I tried to wake up my wife by ringing the doorbell, but she was fast asleep, so I got a ladder from the shed in the garden, put it against the wall, and began climbing towards the bedroom window. I was almost there when a sarcastic voice below said,39。t think the windows need cleaning at this time of the night.39。I looked down and nearly fell off the ladder when I saw a policeman. I immediately regretted answering in the way I did, but I said, 39。So do I,39。Excuse my interrupting you. I hate to interrupt a man when he39。 Well, I39。 I said. 39。ve forgotten my key.39。39。 he called.My key,39。 Lesson93 A noble gift 崇高的禮物L(fēng)esson94 Future champions 未來的冠軍Lesson95 A fantasy 純屬虛構(gòu)39。 she asked.How did your clothes get into such a mess ?39。39。 answered the Ambassador drily. 39。Good heavens!39。And where were you at the time ?39。39。 answered the Ambassador. 39。致使雨水、污水不能及時收集排除，形成雨、污水漫流，已經(jīng)影響居民生活和環(huán)境衛(wèi)生。某些單位將有害有毒和帶易燃物的廢水排入下水道，而下水道又未設(shè)水封井和通氣井。3) 城市污水未經(jīng)處理直接排入水體，污染了環(huán)境某區(qū)污水處理設(shè)施及排污管道不完善，污水未經(jīng)處理直接排放，造成水體污染嚴(yán)重，不利于區(qū)域水體資源的保護(hù)利用，對下游生態(tài)環(huán)境有較大影響。因此，為了保證某區(qū)人民正常的生產(chǎn)、生活要求，適應(yīng)城市經(jīng)濟(jì)社會發(fā)展的需要，建設(shè)城市基礎(chǔ)設(shè)施，做好城市生活污水的處理和處置工作刻不容緩，是非常必要的。區(qū)政府對城區(qū)水體和環(huán)境保護(hù)十分重視，嚴(yán)格控制工業(yè)廢水、生活污水的污染，加大力度對工業(yè)廢水的監(jiān)督和治理，全面推行排污許可證制度，實行排污總量控制。作為某區(qū)的納污水體，為了保護(hù)湘江水體水質(zhì)和生態(tài)環(huán)境，與城市建設(shè)同步污水處理工程，是非常必要的。新建污水處理廠必須采取除磷脫氮工藝。 提高生活質(zhì)量和堅持走可持續(xù)發(fā)展的道路環(huán)境保護(hù)是衡量人民生活水平的一個重要標(biāo)志。某區(qū)近年來發(fā)展快，經(jīng)濟(jì)增長迅猛，人民生活富裕，社會繁榮穩(wěn)定，但伴隨著經(jīng)濟(jì)開發(fā)區(qū)建設(shè)的進(jìn)行，對生態(tài)環(huán)境的破壞將會加劇。如何著力于環(huán)境、文化景觀和高效服務(wù)設(shè)施的建設(shè)、保持經(jīng)濟(jì)的可持續(xù)發(fā)展，在建設(shè)城市的同時，建設(shè)適合國情、省情和當(dāng)?shù)貙嵡榈奈鬯幚韽S是當(dāng)務(wù)之急，是十分必要的?？傮w規(guī)劃中提出以基礎(chǔ)設(shè)施建設(shè)為基礎(chǔ)，以生態(tài)環(huán)境保護(hù)為根本，以經(jīng)濟(jì)結(jié)構(gòu)調(diào)整為主線，大力發(fā)展支柱產(chǎn)業(yè)，推進(jìn)包括農(nóng)業(yè)現(xiàn)代化在內(nèi)的工業(yè)化進(jìn)程和城鎮(zhèn)化進(jìn)程，適當(dāng)擴(kuò)大鎮(zhèn)區(qū)規(guī)模，加強(qiáng)某鎮(zhèn)作為某區(qū)中心城鎮(zhèn)的職能，積極主動拓展水運(yùn)交通和開發(fā)旅游潛力，加強(qiáng)與周邊城鎮(zhèn)的職能，積極主動拓展水運(yùn)交通和開發(fā)旅游潛力，加強(qiáng)與周邊城鎮(zhèn)的合作與交流，全面提高和增強(qiáng)城鎮(zhèn)核心競爭能力，將某鎮(zhèn)建設(shè)成為區(qū)域性綜合服務(wù)功能較強(qiáng)的現(xiàn)代化城鎮(zhèn)，成為經(jīng)濟(jì)繁榮、社會文明、環(huán)境優(yōu)良、具有濃郁湖鄉(xiāng)特色的生態(tài)田園城鎮(zhèn)。 城鎮(zhèn)排水規(guī)劃分析1) 規(guī)劃原則a) 合理選擇排水體制，使排水規(guī)劃既能解決城區(qū)排水問題，又能改善城區(qū)生活居住環(huán)境。c) 分區(qū)排水，排污與排漬相結(jié)合，加強(qiáng)調(diào)蓄，逐步雨污分流。2) 排水體制近期采用截流式合流制排水體制，遠(yuǎn)期采用雨污分流排水體制。經(jīng)污水處理廠處理后排入水體的污水，應(yīng)符合《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》(GB189182002)。 污水量預(yù)測 預(yù)測年限的確定城市污水處理工程屬于城市建設(shè)的基礎(chǔ)設(shè)施，應(yīng)與城市建設(shè)相配套，且適度超前，以促進(jìn)經(jīng)濟(jì)發(fā)展。 服務(wù)區(qū)域人口根據(jù)某區(qū)人口統(tǒng)計數(shù)據(jù)，2008 年底，某鎮(zhèn)鎮(zhèn)區(qū)總?cè)丝跒?2150 人，其中規(guī)劃范圍內(nèi)城鎮(zhèn)人口42050 人，常住人口41750 人，暫住人口300 人（汩羅航運(yùn)總公司常住某鎮(zhèn)約5000 人口未列入統(tǒng)計）。根據(jù)統(tǒng)計結(jié)果顯示，2001 年某鎮(zhèn)建成區(qū)人口33071 人，2008 年鎮(zhèn)區(qū)人口42161人，六年來城鎮(zhèn)人口持續(xù)增長，人口年均綜合增長率為3%，年均增長人口1515 人。參考《某市市域城鎮(zhèn)體系規(guī)劃20022020》確定的某市城鎮(zhèn)人口年平均增長率20022010 %，20112020 %，綜合考慮各方面的因素，確定某區(qū)城鎮(zhèn)人口年均綜合增長率20092011 %，20122020 %。2) 指數(shù)增長法運(yùn)用指數(shù)增長法預(yù)測未來人口規(guī)模，按下式計算：Pt= P0er3) 預(yù)測結(jié)果根據(jù)以上兩種預(yù)測方法的計算。 城鎮(zhèn)需水量預(yù)測影響城市供水規(guī)模及其增長速度的因素很多，諸如人口規(guī)模、工業(yè)產(chǎn)值、生產(chǎn)用水、水資源條件、水價、節(jié)水措施及供水的政策等。經(jīng)綜合分析研究，采用人均綜合用水量指標(biāo)法和分項指標(biāo)法分別進(jìn)行預(yù)測。綜合用水定額和用水普及率也將逐年遞增。綜合用水量：Q1=qnp其中：Q1——綜合用水量(m3/d)；q——綜合用水定額(L/)；n——人數(shù)；p——用水普及率。 綜合用水量預(yù)測表規(guī)劃年份2011 年2020 年城鎮(zhèn)人口規(guī)模(萬人)綜合用水定額(L/)360500用水普及率(%)9095綜合用水量(萬m3/d)b) 分項指標(biāo)法城市總用水量包括生活用水量、生產(chǎn)用水、道路廣場澆灑用水、綠化用水以及城市管網(wǎng)的漏損、消防用水等其他用水，分項指標(biāo)法就是將各單項指標(biāo)用水分項預(yù)測再統(tǒng)一累加計算出總用水量。生活用水額定和用水普及率也將逐年遞增。生活用水量：Q1=qnp其中：Q1——綜合用水量(m3/d)；q——綜合用水定額(L/)；n——人數(shù)；p——用水普及率。 生活用水量預(yù)測表規(guī) 劃 年 份2011 年2020 年城鎮(zhèn)人口規(guī)模(萬人)生活用水定額(L/)230300用水普及率(%)9095生活用水量(萬m3/d)2) 生產(chǎn)用水量某區(qū)是以經(jīng)濟(jì)結(jié)構(gòu)調(diào)整為主線，大力發(fā)展支柱產(chǎn)業(yè)，推進(jìn)包括農(nóng)業(yè)現(xiàn)代化在內(nèi)的工業(yè)化進(jìn)程和城鎮(zhèn)化進(jìn)程。根據(jù)某鎮(zhèn)工業(yè)現(xiàn)狀和發(fā)展規(guī)劃，鎮(zhèn)區(qū)的工業(yè)企業(yè)相對較多，確定污水處理廠納污區(qū)生產(chǎn)用水量占生活用水量的比例分別為2011 年30%，2020 年為50%。4) 其他用水量其他用水量主要包括管網(wǎng)漏損水量、不可預(yù)見水量，按生活用水量的15%計。 分項指標(biāo)法用水量預(yù)測表規(guī) 劃 年 份2011 年2020 年城鎮(zhèn)人口規(guī)模(萬人)生活用水量(萬 m3/d)生產(chǎn)用水量(萬m3/d)澆路、綠化用水量(萬m3/d)其他用水量(萬m3/d)總用水量(萬m3/d) 城鎮(zhèn)污水量預(yù)測一般來說，城市用水中僅有75%～90%能夠成為污水排放。 污水量預(yù)測結(jié)果表規(guī) 劃 年 份2011 年2020 年城鎮(zhèn)總用水量(萬m3/d)產(chǎn)污系數(shù)截污系數(shù)城鎮(zhèn)預(yù)測污水量(萬m3/d) 工程建設(shè)規(guī)模根據(jù)某區(qū)污水量預(yù)測，城市污水處理工程，按照統(tǒng)一規(guī)劃、分期建設(shè)、遠(yuǎn)近結(jié)合，以近期建設(shè)為主，適當(dāng)超前的指導(dǎo)思想，分期建設(shè)，工程規(guī)劃總規(guī)模為3 .0萬m3/d，分兩期實施，其中：2011 萬m3/d；2020 萬m3/d。污水處理廠廠址的選擇應(yīng)符合以下原則：1) 在城市水系的下游并應(yīng)符合供水水源防護(hù)要求；2) 在城市夏季最小頻率風(fēng)向的上風(fēng)側(cè)；3) 與城市規(guī)劃居住、公共設(shè)施保持一定的衛(wèi)生防護(hù)距離；4) 靠近污水、污泥的排放和利用地段；5) 應(yīng)有
