寬葉香蒲人工濕地對鉛鋅礦廢水凈化效能的研究

摘要： 研究以寬葉香蒲(Typha latifolia)為優(yōu)勢種的人工濕地系統(tǒng)對廣東省韶關(guān)市凡口鉛/鋅礦采礦廢水凈化效能.研究結(jié)果表明:寬葉香蒲人工濕地生態(tài)系統(tǒng)能有效地凈化鉛/鋅礦廢水.經(jīng)系統(tǒng)處理后，COD、固體懸浮物、Pb、Zn、Cu和Cd的去除率分別為92.19%、99.62%、93.98%、97.02%、96.87%和96.39%，水質(zhì)得到明顯改善.主要污染物TSS、Pb、Zn、Cu和Cd等均達到工業(yè)標準，并接近農(nóng)灌標準. Abstract： The efficiency of Typha latifolia Linn man-made wetland to treat the wastewater from a Pb/Zn mine at Shaoguan, Guangdong Province, was evaluated by monitoring water quality. The results show that the Pb/Zn mine wastewater could be effectively purified by the man-made wetland. After passing through the system，the water quality was obviously improved. The total suspended solids (TSS) reduced by 99.62%, COD by 92.19%，Pb by 93.98%，Zn by 97.02%，Cu by 96.87%，Cd by 96.39% respectively. With the restoration of wetland, the effectiveness of wetland on wastewater purification was also significantly improved. 作 者： 作者單位： 期 刊： 深圳大學(xué)學(xué)報（理工版）   ISTICEIPKU   Journal： JOURNAL OF SHENZHEN UNIVERSITY SCIENCE & ENGINEERING   年，卷(期)： 2000, 17(2)  分類號： X703  關(guān)鍵詞： 寬葉香蒲    人工濕地    鉛/鋅礦廢水    廢水處理    Keywords： Typha latifolia man-made wetland    mine wastewater    purification
