原文摘要

Low impact development (LID) systems are increasingly used to manage stormwater, but they have limited ca-pacity to treatstormwater—a resource to supplement existingwater supply in water-stressed urbanareas. To en-hance their pollutant removal capacity, infiltration-based LID systems can be augmented with natural orengineeredgeomedia that meet the following criteria: they should be economical, readily available, and have ca-pacity to remove a wide range of stormwater pollutants in conditions expected duringintermittent infiltration ofstormwater. Biochar, a carbonaceous porous co-product of waste biomass pyrolysis/gasification, meets all thesecriteria. Biochar can adsorb pollutants, improve water-retention capacity of soil, retain and slowly release nutri-ents for plant uptake, and help sustainmicrobiota in soil and plants atop; all these attributes could help improveremoval of contaminants in stormwater treatment systems. This article discusses contaminant removal mecha-nisms by biochar, summarizes specific biochar properties that enhance targeted contaminants removal fromstormwater, and identifies challenges and opportunities to retrofit biochar in LID to optimize stormwatertreatment

原文摘要簡述

低影響開發(LID)系統越來越多用於管理雨水,但它們對調整水的能力有限-這是一種補充缺水城市區域現有水供給的資源。為了提高其污染物去除能力,在過濾性的LID系統中,可以使用符合以下標準的天然工程地質系統進行增強:在間歇性的過濾暴雨過程中,它們應該具有經濟上、容易獲得、並且能夠在預期的條件下去除各種各樣的雨水污染物。Biochar是廢棄生物質熱裂解/氣化的碳質多孔產物,符合所有這些標準。生物炭可以吸附污染物,提高土壤的保水能力,保留和緩慢釋放營養物質,並幫助維持土壤和植物頂部的微生物群;所有這些屬性可以幫助改善雨水處理系統中污染物的去除。本文討論生物炭去除污染物的機致,總結特定的生物炭特性,增強從污水中去除目標污染物的能力,並確定在優化雨水處理時,在LID中改造生物炭的挑戰和機遇。
