Treatment Effect of Multilayer Vermifiltration on Living Wastewater

Abstract:

Article Preview

Former studies and application of vermifiltration process to organic wastewater treatment has given an affirmative effect for the pollutant removal in wastewater. It could be used for the disperse wastewater treatment, especially for rural living sewage. We developed a new multilayer vermifiltration system in this study, expecting to enhance this ability for the disposal of rural living sewage. The result showed that all the COD, BOD5 and SS values in outflow after vermifiltration could meet GB18918-2002. The removal rates of COD,BOD5 and SS were above 75%, 85% and 90% respectively. The N and P could be partly removed. These preliminary results give a positive prospective for the application of multilayer vermifiltration in rural sewage treatment in the future.
