不少人都知道，在上海中心城區楊浦區有一座鳥語花香的花園工廠——東區汙水處理廠，而上海排水人還知道上海曾有一座西區汙水處理廠。可大家是否知道，在遙遠的澳洲墨爾本也有東廠西廠，還是國際上公認的鳥類天堂，全球重要的溼地，今天《淨水技術》小編就為各位讀者一一道來。
The Eastern Treatment Plant was opened in 1975 at Bangholme to serve Melbourne's growing population and to support the Western Treatment Plant. The plant sits on 1,100 hectares and treats about 330 million litres of sewage a day - 40% of Melbourne’s total sewage.
為了服務墨爾本日益增長的人口並支援西區汙水處理廠，東區汙水處理廠於1975年在班霍爾梅建成。該廠佔地1,100公頃，日處理能力33萬噸——相當於墨爾本汙水總量的40%。
The current sewage treatment process follows two stages: primary treatment and secondary treatment. Just before the treated effluent flows out of the plant to be recycled or released to the environment, it is disinfected with chlorine.
東區汙水處理廠目前為二級處理，出水在作為再生水出廠或排放到自然環境之前進行加氯處理。
The Eastern Treatment Plant is home to a large native bird population, including many species of regional, state and national significance.
東區汙水處理廠是當地許許多多鳥類的家園，其中有很多是地區、州以及澳大利亞全國的重要鳥類。
The plant also provides habitat for large numbers of migratory waders. The most famous are sharp-tailed sandpiper (from northern Siberia), red-necked stint fly (from eastern Siberia) and latham's Snipe from Japan. These birds arrive around August then leave for the northern hemisphere between February and May.
東區汙水處理廠也是許多侯鳥類涉禽的棲息地。最著名的是來自西伯利亞北部的尖尾鷸、來自西伯利亞東部的赤頸濱鷸以及來自日本的拉塞恩鷸。這些鳥大約在8月飛抵，然後在來年2月到5月間飛回北半球。
The Western Treatment Plant is Melbourne's first sewage treatment plant. In 1888 a Royal Commission was carried out to come up with a solution to Melbourne’s waste problems. In 1892, the newly established Melbourne and Metropolitan Board of Works (MMBW) began buying land at Werribee, chosen for its low rainfall and suitable soils. Western Treatment Plant (then known as Werribee Farm) began operations in 1897.
西區汙水處理廠是墨爾本第一座汙水處理廠。1888年，一個皇家委員會開始著手尋找應對墨爾本廢棄物問題的解決方案。1892年，墨爾本及大都會工部局開始在威利比地區購買土地，因為那裡降水少、土質適宜。西區汙水處理廠於1897年開始運行（當時稱為威利比農場）。
The Western Treatment Plant in Werribee is about 10,852 hectares in area and is a world leader in technical and environmental innovation. It treats about 52% of Melbourne's sewage, or about 485 million litres a day. This serves about 1.6 million people in the central, northern and western suburbs.
位於威利比地區的西區汙水處理廠佔地10,852公頃，是一家在技術與環境創新方面世界領先的汙水處理廠。該廠日處理能力48.5萬噸——相當於墨爾本汙水總量的52%，為居住在中心城區、北郊與西郊共計160萬人提供服務。
There are three modern lagoon systems at the Western Treatment Plant. A modern lagoon system is typically made up of 10 large ponds, each of which can hold around 600 million litres of water. There are two main types of ponds used in lagoon treatment - anaerobic and aerobic. It usually takes around 30 to 35 days for sewage to be processed through each of the plant’s three modern lagoons.
西區汙水處理廠擁有三套現代氧化塘汙水處理系統。一套典型的現代氧化塘汙水處理系統由10個大型池塘組成，每個能容納60萬噸水。氧化塘處理流程主要採用兩種類型的池塘——厭氧塘與好氧塘。汙水在該廠三套現代氧化塘汙水處理系統中每一套的停留時間為30~35天。
The Western Treatment Plant is one of the most popular sites for bird watching in Victoria with 284 species of bird recorded at the site from all over the world. The plant’s lagoons, grasslands and coastline provide an ideal and varied habitat for birds. It is listed by the Ramsar Convention as a wetland of international significance and is a haven for tens of thousands of birds.
西區汙水處理廠是維多利亞州最著名的觀鳥地點之一。根據記錄，這裡有來自世界各地的284種鳥類，廠內池塘、草地與海岸線成為理想的、多樣化的鳥類棲息地。該廠被《拉姆薩爾公約》列為在國際上具有重要影響的溼地，同時是幾萬隻鳥類的天堂。
