Japanese professor provides guidance on Zhuxi River remediation project

Tainan Community University (台南社大) invited Japanese professor Watanabe Feng-bo (渡邊豐博) to provide some concrete proposals for a future remediation project on Tainan’s Zhuxi sewage treatment system. Tainan Water Resources Bureau also provided proposals for the sewage remediation in Zhuxi and hopes to improve the water quality without the use of a chemical purification plant, instead using a more ecological approach in which household sewage will first be sent by pipeline to a purification plant before entering the Zhuxi River.  

Professor Watanabe believes an ecological purification system that cultivates purification bacteria held in gravel beds and fixed in place by wooden stakes could be employed to break down sewage from Zhuxi; additionally, plants efficient in purifying water could be planted around the edges. Such a method could achieve the required level of water purification without relying on advanced science and technology. Professor Watanabe said that regardless of whether one uses bacteria, plants, sewage treatment plants or water purification systems, the source of all pollution is created by us at home. If we simply improved our attitude towards water use, then we wouldn’t need to worry about water pollution problems!

竹溪整治 日本教授有話說

台南社大邀請日本渡邊豐博教授，對於未來台南竹溪汙水整治提出具體的改善方案，台南市政府水利局也針對竹溪的汙水整治提出方法。水利局希望藉由水質淨化廠來改善竹溪汙水問題，並非如汙水處理廠用化工的方式淨水，而是採用較生態的方法，先擷取排到竹溪的家庭汙水，管線送到水質淨化廠，淨水後再送回竹溪。

渡邊教授則認為可以採用生態自然淨水的方式，先分析竹溪汙水的性質，使用木樁、礫石培養對應的淨水細菌，周邊種植的植物可以做為淨水之用，這樣在不仰賴科技下，達到淨水。渡邊教授更認為，不單是依靠細菌、植物或者汙水處理廠、水質淨化廠，回到源頭是製造汙水的我們本身，如果我們能改進自身用水的態度，根本不必擔心水源汙染的問題。
