- 摘要：为了提高污水处理的质量和效率,将高效的生物处理技术——膜-生物反应器(SMBR)与生态净化技术——复合垂直流人工湿地(IVCW)进行有效复合而成的SMBR-IVCW复合系统应用于高浓度综合污水的高效处理与回用中.通过对不同水力负荷组合条件下SMBR-IVCW系统对污染物净化效果的比较,得到了该复合系统的较好水力组合条件.结果表明,SMBR-IVCW具有良好的净化功效及稳定性,SMBR单元在有机物的去除、硝化作用中起到主要贡献,而IVCW单元在反硝化脱氮、深度除磷等方面进一步补充,两者的有机结合能充分发挥各自的优势.并得到了较优的水力负荷组合条件:SMBR为1000L·d-1,IVCW为375mm·d-1;在该条件下,SMBR-IVCW系统总停留时间为19.22h,处理后出水中CODCr、TP、NH4+-N浓度分别为11.0、0.086、0.44mg·L-1,均可达地表水环境质量Ⅲ类标准(GB3838-2002).SMBR-IVCW系统在此类污水处理方面具有良好的潜力.
- Abstract：In order to improve the quality and efficiency of wastewater treatment,a combination of SMBR and IVCW (Integrated Vertical-flow Constructed Wetland),which are representatives of biological treatment technology and ecological purification technology,was applied to treat high concentration wastewater for reuse.By comparing the purification effects of the SMBR-IVCW system under different hydraulic loading rates,the optimal hydraulic conditions of the combination system were obtained.The results showed that this combined system had good stability and high purification performance.The SMBR mainly contributed to removing the organics and nitrification,while the IVCW made contributions to the denitrification and further dephosphorization.The optimal hydraulic loading rates of the SMBR and IVCW were 1000 L·d-1 and 375 mm·d-1 respectively.Under those conditions,the concentrations of CODCr,NH4+-N and TP in the effluent of the system were 11.0 mg·L-1,0.086 mg·L-1 and 0.44 mg·L-1 respectively,which came up to the Class Ⅲ of the national environmental quality standards for surface water.The SMBR-IVCW shows good potential for treating such wastewater.
