Drainage nets draw global attention

濾水網備受世界關注

Australian city of Kwinana keeps waste out of water with huge 'socks' It has been described as the "simple pollution solution", a sock-like net that fits over a stormwater drain outlet to collect rubbish before it enters a waterway.

澳大利亞城市奎那那（Kwinana）正用其巨“襪”過濾垃圾。該方法被譽爲“解決污染的簡單方法”：將一種類似襪子的過濾網安裝在排水管口，過濾各種垃圾，還大家一條清澈河流。

For years, the Australian city of Kwinana, just south of Perth in Western Australia, had been battling with waste such as plastic containers, bottles, paper and vegetation discharged into the city's waterways by stormwater drains.

澳大利亞城市奎那那（位於珀斯南部）多年來一直與排入城市水道的垃圾作鬥爭，如塑料容器、瓶子、紙張和植物等。

It is a problem not unique to Kwinana, a city of 40,000 people. Cities around the world suffer from the same pollution problem. Last year, the Kwinana council came up with a response and the results were "staggering", said a spokesperson for the council.

不僅奎那那（常住人口4萬）受到這一問題困擾，世界各地的城市都面臨着同樣的污染問題。去年，奎那那委員會做出迴應，結果令人“大吃一驚”，委員會發言人說道。

In March 2018, nets were fitted to the mouths of two local stormwater drains to trap litter and debris. Within three months, 370 kilograms of rubbish had been collected. The result was so good and the council posted pictures of the nets on its social media page. Since then, the council's post has gathered more than 25 million hits.

2018年3月，我們將濾水網安裝在當地的兩個排水管上，過濾各種垃圾、殘渣。3個月內，共收集了370公斤垃圾，效果顯著。委員會在其社交媒體主頁上發佈了濾水網的照片，獲得2500萬人點贊。

"We have received inquiries from local government agencies and cities from around the world about the 'sock'," the spokesperson told China Daily.

“奎那那當地政府機構及世界各城市都向我們詢問‘濾水襪’的問題，”發言人對《中國日報》說道。

The Ecosol Net Tech (drain sock) consists of a stainless-steel sleeve extension that is fitted into existing, or new, outlets, and a removable polyethylene net, which, when full of pollutants, disengages during rainfall, effectively eliminating the risk of flooding during peak-flow storms.

Ecosol濾網技術（濾水襪）由不鏽鋼管（可安裝在現有的或新的排水口）和一個可更換的聚乙烯網（裝滿垃圾後，會在下雨天脫離）組成，有效消除了大暴雨期間洪災的風險。

Easily installed into most drainage networks, the unit's simple design has a unique net release mechanism that eliminates any adverse effects when the bag fills during torrential downpours. The drain sock is now a regular feature on stormwater drains around the city. It has also been found to collect much smaller particles, including fine sediments.

濾水網安裝簡便，其簡單的設計具有獨特的濾網釋放機制，可消除傾盆大雨期間濾網過滿所帶來的不利影響。現在，濾水襪已成爲城市排水管的特徵。現已證明，濾水網可過濾更小的顆粒，如細沙。

"Of course, the nets don't capture liquid waste but by capturing solid waste we help protect and minimize the risk to wildlife," the spokesman said. "This efficiency means the return on capital investment will be realized in the short term as well as cleaner reserves, higher efficiency and improved safety outcomes.

“當然，濾水網無法過濾液體垃圾，但過濾固體垃圾也可以幫助我們保護並最大限度的降低野生動物受害的風險，”這位發言人說道。“濾水網十分高效，這意味着資本投資將在短期內回籠，與此同時，蓄水池將更乾淨、效率將更高、安全性將更強。”
