城市景观水体修复及受污染水生植物的处置

Restoration of Urban Landscape Water Bodies and Disposal of Contaminated Aquatic Plants

随着城市工业化发展,城市景观水体污染日益加重,水体修复技术选择及其影响成为当今环境工程领域的热点问题。本文通过总结目前城市景观水体的水质污染指标特征,对比分析了景观水体修复的物理法、化学法和生物生态技术,明确了人工湿地及生态浮岛技术在处理景观污染水体时的优势,同时也说明了该工艺存在产生受污染水生植物废弃物的问题。为此对该类生物质废弃物的处置技术,包括压缩、堆肥、焚烧及热处理等,进行了技术和经济的分析,为城市景观水体生态修复技术的推广应该提供技术支持。

With the development of urban industrialization, the pollution of urban landscape water bodies is becoming increasingly severe, and the selection and impact of water restoration technologies have become a hot topic in the field of environmental engineering today. This article summarizes the characteristics of water quality pollution indicators in urban landscape water bodies, compares and analyzes the physical, chemical, and biological ecological technologies for landscape water body remediation, clarifies the advantages of artificial wetlands and ecological floating island technologies in treating landscape polluted water bodies, and also illustrates the problem of producing contaminated aquatic plant waste in this process. For this purpose, a technical and economic analysis was conducted on the disposal technology of this type of biomass waste, including compression, composting, incineration, and heat treatment, to provide technical support for the promotion of urban landscape water ecological restoration technology.
