水看世界 | 鸟类天堂——墨尔本东区、西区污水处理厂
导读
不少人都知道，在上海中心城区杨浦区有一座鸟语花香的花园工厂——东区污水处理厂，而上海排水人还知道上海曾有一座西区污水处理厂。可大家是否知道，在遥远的澳洲墨尔本也有东厂西厂，还是国际上公认的鸟类天堂，全球重要的湿地，今天《净水技术》小编就为各位读者一一道来。
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.
为了服务墨尔本日益增长的人口并支援西区污水处理厂，东区污水处理厂于1975年在班霍尔梅建成。该厂占地1,100公顷，日处理能力33万吨——相当于墨尔本污水总量的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.
The Eastern Treatment Plant is home to a large native bird population, including many species of regional, state and national significance.
东区污水处理厂也是许多侯鸟类涉禽的栖息地。最著名的是来自西伯利亚北部的尖尾鹬、来自西伯利亚东部的赤颈滨鹬以及来自日本的拉塞恩鹬。这些鸟大约在8月飞抵，然后在来年2月到5月间飞回北半球。
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.
西区污水处理厂是墨尔本第一座污水处理厂。1888年，一个皇家委员会开始着手寻找应对墨尔本废弃物问题的解决方案。1892年，墨尔本及大都会工部局开始在威利比地区购买土地，因为那里降水少、土质适宜。西区污水处理厂于1897年开始运行（当时称为威利比农场）。
位于威利比地区的西区污水处理厂占地10,852公顷，是一家在技术与环境创新方面世界领先的污水处理厂。该厂日处理能力48.5万吨——相当于墨尔本污水总量的52%，为居住在中心城区、北郊与西郊共计160万人提供服务。
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.
