在新加坡大部份的用水是來自向馬來西亞購買和來自於蓄水池,新加坡和馬來西亞簽約的原因是因為新加坡地小人多,降雨少,造成新加坡是全世界可以用的水量最少、人民能用的水量最少的國家。
我們10:30來到新生水博物館,了解到新加坡當地是怎麼解決缺水問題,新加坡這邊的整個水的開始到結束。因為新加坡缺乏水資源,於是早在1961他們和鄰國馬來西亞在聯合國簽約買水(1961~2016),但因為馬來西亞常常調整水價和危脅停水使得新加坡決定當2016到期便不在續約了,所以面對未來”水”的問題新加坡在1998年開發了回收並淨化污水的技術,並欲記2060將會共應全國50%的用水。
解說員在一開始的時候有講到在這個世界上只有0.8%的水是乾淨而且是可以用來飲用的。新加坡的資源,整個過程是從蒸發海水開始,再來就是降雨到新加坡的水庫,把雨水集中,在一起過濾加工,接下來就是送到民生給予用水,民眾用完之後的污水,再由流管進一步淨水,這時候的淨水過程就比較複雜,淨完水之後,便可繼續讓人民使用。
新加坡的飲用水是從四個不同方法加工或收集的,第一是利用過濾的雨水,第二是與鄰國馬來西亞的進口水、第三種是新生水,也就是今天在工廠看到的回收水和最後是經過淡化的海水
整個淨化污水的步驟是先將水流進集水處裡裡面有細長的管子將水抽上去。管子有細孔,一個細孔大約0.04mm,排除雜質。(還不能喝因為有重金屬和病毒)接下來過濾完的水進入到下一個階段。到了第二階段,有一種特殊的壓力管,壓力將水由外擠進內部,在過程中經過的細孔比第一階段的孔還小,是大概0.0004mm的小孔,這時候,病毒進不去,剩下的水就很乾淨!這時候的水可以喝了但是還需要安全手續!!第三步驟,使用紫外線殺菌整個過程只需要5分鐘。完整過程下來只有75%的水可以使用,因為剩下的水太髒不能給人民使用。
這種過程其實是參考美國NASA太空的點子,而且水分子很小,其他雜質可以排除在外,才能利用這方法回收舊水製造新生水。最後解說員講了個故事說以前有些參訪的人來新生水工廠參訪。最後都會發給每人一人一小罐新生水,但是那些參訪者卻沒有喝。可能是知道的些新生水也是有包含回收馬桶的水吧。他鼓勵我們每人拿一瓶新生水,同學們聽完了講解後反而覺得這樣的過濾技術是值得相信的,還有同學想再喝就多拿了幾瓶水帶回去。
Most of the water that
Singapore used is brought from Malaysia and reserviors. And the reason why
Singapore and Malaysia signed a contract of water is that Singapore is too
small and the population is too many. It makes Singapore become a country that has
the least water supply for each person around the world.
We came to NEWater Vistor
Centre at 10:30 to know how Singapore face the problem of water. Because the
problem of water, Singapore signed the contract of buying water from Malaysia.
The contract was signed in 1961, and it will expire in 2016. Singapore don’t
want to continue the contract because Malaysia increased the price of water and
threatened Singapore by stopping the water. So Singapore tried to solve the
problem by themselves. They used the “newater” to solve the problem, they think
it can produce 50% of the water they used at 2060.
We knew that only 0.8% of water
on the earth is drinkable. Singapore gets the water mainly from the rain. The
rain comes to their reservoir, then the water will be cleaned and the people
will use it. The used water will be recycled again, and this time the water
will be cleaned more carefully. After that, the water will be clean and the
people in Singapore will use it again.
The water of Singapore came
from four ways. The first is local catchment. The second is imported water. The
third is newater and the last is desalinated sea water.
There are 3 steps to produce
the newater. The first is pumping the water into a stick. The surface of the
stick is full of little holes about 0.04mm. The second step is pumping the
water into a stick again, but this time the holes on the stick are much
smaller, only about 0.0004mm. After this step, the water will be very clean and
drinkable. The third step is to use UV light to kill the bacteria and virus
left. These steps can recycle 75% of the water, the other 25% is dirty water
that can’t be used.
They got the idea from NASA.
NASA use a similar way to recycle the astronauts’ water. The molecule of H2O is
very small, so they can use small holes to clean the water, and keep the
bacteria outside of the holes. Some people who visited the newater factory
still can’t believe the water is clean because the water came from used water
like toilet, but everyone believe it at last because they give you a bottle of
newater, and everyone agree it’s clean after drinking it. We have some
classmates even took some more after drinking it.
結束了上午的行程,我們來到了新加坡著名的觀光勝地-聖淘沙。具嚮導說,聖淘沙之前的名字是絕後島,是以前海盜對決分張的地方。而我們今天的目的則是前往水族館。與一般水族館不同之處,新加波結合了明朝鄭和下西洋這段歷史。利用劇場的方式,我們跟著動線進入一艘假船,4D的投影把我們帶入了完全不同的世界,在不知不覺中我們也到達了「深在海底的水族館」。沿著步道觀賞各種千奇百怪的魚,我就像發現新世界的冒險家,快門不停的按,停都停不下來。
今天大概是汗流最少的一天了吧!因為大部分的行程都在室內,在離開水族館後來到了一個可以坐纜車和玩溜溜車的地方。主要是搭乘溜溜車往下滑,並選擇左右兩條道路到達山下再以覽車往上搭回起點的一個路程。其中,有不少同學開著溜溜車較競、搭著纜車尖叫等等。各種突發狀況,回想起來其實還蠻有趣的。
在過兩天就要回台灣,再經過這麼多不同的體驗之後。我覺得我重新拓展了視野。看見不一樣的事物,讓我了解到原來別的國家是這麼的厲害,有著這麼不一樣又創新的作法。而這次的教育旅行,我確信新的知識又在腦中更新了幾頁。
We went to the famous visiting
location – Sentosa. According to our tour guide, Sentosa was first called
Blakang Matti, where the pirates split up their booty. Our destination today was
the world’s largest aquarium; it’s special for its combination with Zeng He’s
expedition. We went into a 4D movie theater, which took us to a journey toward
a different world. We were taken to the entrance of the aquarium as we’re
watching the movie. Along the path, there were many different kinds of fishes,
it was like exploring a new world.
Our schedules were all indoors;
it’s probably the coolest day in the trip. After visiting the aquarium, we went
to a place where we can take luge and sky tram. Luge is a ride that takes you
down the track and you can take the sky tram back to the top. There were many
of us racing each other as our way down, or screaming on the sky tram. It was
actually interesting.
We’ll be back to Taiwan in two
more days. After going through these different experiences, it felt like all of
us have learned many new things. After seeing different things, it made me
understand that there are more to learn from other countries. I believe that we’ve
learned and grew through this educational trip to Malaysia and Singapore.
學生心得
平常我們在很多國家都無法飲用自來水,只能飲用過濾過的水,但其中有一國就可以,就是小國家新加坡,新加坡各處的水都可以拿來飲用,因為新加坡建設了新生水製造廠,它是幫新加坡製造再用水的地方。新加坡因水源較少所以跟鄰國朋友馬來西亞租水來製造再用水,今天參觀了新生水製造廠終於了解到,製造再生水需經過精密細節及很多關卡,才能產生出新鮮的再生水,再生水除了能飲用及使用外也是環保水源,從髒水、我們使用過的水及雨水經過吸、壓、滲透、過濾和紫外線殺菌形成再生水,一個水循環,這樣一來我們就不必再浪費這些水源。這次的參觀讓我對新生水越來越喜歡及好奇。(曾芊芊)
今天上午參觀完新生水工廠我們在下午來到了聖淘沙。首先我們來到了水族館這裡唯一跟其他水族館不同的是大門一進去可以看到一艘超特別的大船,船頭上有一個獅子頭眼睛是紅色的超酷,再來我們開始玩溜溜車它往下滑時就像賽車一樣超爽,最後我們搭兩腳懸空的纜車集合結束了這一天。(林家德)
Today’s trip was crazy, we
played a cool game called Luge .It’s like a skateboard but with a little
difference. You sit on the Luge and you can control it by yourself. If you pull
the handle up, the Luge will start to move. We played so fast that we almost bumped
in together, but it was fun. There were two roads in the game, and you needed
to keep changing your side on one of them, and controlled it very careful on
the other or you might be hurt easily. At last it was really a nice trip, wish
I can play it again next time.(陳沛甫)
今天下午去海事博物館,裡面是有關鄭和下西洋的歷史,它用多種方式來呈現過程,例如:動化劇場、4D體驗劇場等等,來加深我們的印象、趣味化。樓下則是全世界最大的水族館,我們看到各式各樣以前不曾看過的海洋生物、巨大的水族箱、環繞式的水族箱,個個令人嘖嘖稱奇。 接下來我們到了一個像遊樂場的區域玩「溜溜車」,我們對這個名字並不熟悉,非常好奇它到底是什麼樣的遊樂設施,好險工作人員有向我們解釋怎麼操作,我們玩溜溜車溜下山,再坐雙腳懸空的纜車上山,沿途看到新加坡的風景,真的很壯觀。(吳育緹)
下午真的是這幾天最好玩的行程雖然天氣燥熱但能夠與同學一同遊覽整個聖淘沙是在好玩不過在兩天就要收心回國了真的很希望可以和同學生活的更久回國後我會很想念這幾天的有趣的海外教育旅行!(林哲宇)
