Sustainable Management of Decontamination Constructed Wetlands: Research on the Industrial and Scientific Development of Aquatic Plants

Abstract

This pilot paper focuses on the suburban constructed wetlands that operate for the main purpose of wastewater treatment and explores the possibility of decontamination constructed wetlands based on the industry-academic model to establish a positive circular economy production chain from the perspective of a sustainable economy. Through a four-stage humanistic investigation process, using focus interviews, literature analysis, expert opinions, field investigations, patent search analysis, context, and decision analysis processes, it is proposed to use plants around the wetland as production products to develop manufacturing, electricity, and gas supply possibility of business and construction products as the main product. The related aquatic plants are developed and utilized in the Republic of China patents, namely, watery plants> root-floating plants> floating water plants> submerged water plants. Among them, the water-protruding plants are fibrous. It is most characterized in textiles, papermaking, board, furniture, etc., followed by biological nutrient solutions or extracts used for fertilization, control, or beauty. Therefore, it is still possible to reuse the wetland plants to develop related innovative products. Provide sustainable management of decontamination constructed wetland as a reference for wise use. Key words: constructed wetlands, sewage treatment, sustainable development, aquatic crops, industry-academic cooperation
