殘缺的衛生現代性或適當的綠色基礎設施？新北市污水淨化型人工濕地的生產與治理

Incomplete Hygienic Modernity or Appropriate Green Infrastructure? The Production and Governance of Constructed Wetlands for Sewage Purification in New Taipei City

本文探討新北市大漢溪沿岸污水淨化型人工濕地的建置、功能與意義。作者運用文獻分析，概述台北都會區污水處理系統化歷程，並歸納促成大漢溪人工濕地建置的趨勢：（1）大漢溪沿岸缺乏分流式污水處理設施；（2）環境主義運動倡議以河濱濕地之淨水生態服務來獲取正當性；（3）都市水岸再發展推動了綠美化與沿岸房地產開發。大漢溪污水淨化型人工濕地體現了衛生現代性的殘缺，但又接軌於環保理念和水岸再發展需求，遂從殘補式除污設施轉化為適當的綠色基礎設施。但是，人工濕地的部署也透露了基礎設施的不均發展，並塑造出遮掩更基本都市問題的生態形象。

The article explores establishment, functions and meanings of the constructed wetlands along the Dahan River, which were built as infrastructure of waste water treatment in the New Taipei City. The authors depict the historical changes of sewage system building in Taipei metropolitan area, attempting to point out the structural forces leading to the ‘infrastructuring’ of constructed wetland: (1) The long-term lack of a well-equipped wastewater treatment system in the Dahan river region. (2) The environmental groups’ advocacy for wetland’s ecological service of purifying and revaluing river to support environmentalism. (3) The agenda of urban waterfront redevelopment has stimulated waterfront landscaping, as well as real estate booms. As a result, the ‘infrastructuring’ of constructed wetlands along the Dahan River just demonstrated an ‘unfinished’ modernity of sanitation, which has been articulated with environmentalism and the trend of waterfront redevelopment since the 1990s. During such process, the constructed wetlands, as a ‘reparative’ waste water treatment, were converted into ‘appropriate’ green infrastructure. However, the deployment of the constructed wetlands embodies uneven development of infrastructure, veiling the basic problems of urban development with ecological images.
