Solar Biogas Digester and Wetland-Pond System for Rural Wastewater Treatment

Abstract:

Solar biogas digester and wetland-pond system treated the wastewater for the rural about 60 families. The system comprised a solar anaerobic baffle digester, an anaerobic filter, a subsurface vertical flow wetland, and an eco pond. The four units were connected in series. The solar digester and the filter produced enough biogas evenly in whole year and provided 80-91% total suspended solids (TSS) removal. The wetland-pond developed aquatic crops, fisheries and waterfowl aquaculture. In this artificial ecosystem, bacterial oxidization, algae photosynthesis and food web degradation greatly reduced COD, BOD₅, TN, NH4-N, TP, and pH of water.
