Abstract

Landfill leachate poses a significant environmental threat. This study examined Non-thermal plasma (NTP) technology for treating landfill leachate after pretreatments to tackle this issue. EC and TDS decreased by over 96 %, COD by 98 %, turbidity by 97 %, color by 93 %, TSS by 98 %, and BOD₅ by 97 %. Phenol levels dropped by more than 98 %, and significant heavy metal removal was achieved: Cd, Hg, Pb, Cu, Ni, Al, Fe, and Zn concentrations were reduced by 90 %, 95 %, 97 %, 92 %, 94 %, 72 %, 65 %, and 77 %, respectively. These findings underscore the potential of NTP technology as a valuable tool for wastewater treatment.

以非热等离子体技术去除垃圾渗滤液中酚类化合物和重金属为重点的综合研究

堆填区渗滤液对环境构成严重威胁。为了解决这一问题，本研究采用非热等离子体（NTP）技术对垃圾渗滤液进行预处理处理。EC和TDS降低96%以上，COD降低98%，浊度降低97%，色度降低93%，TSS降低98%，BOD5降低97%。苯酚水平下降了98%以上，并且实现了显著的重金属去除：Cd、Hg、Pb、Cu、Ni、Al、Fe和Zn浓度分别降低了90%、95%、97%、92%、94%、72%、65%和77%。这些发现强调了NTP技术作为废水处理的宝贵工具的潜力。
