| Abstract | High-rate resourcing disposal tank (HRDT) based on improved septic tank technology was first designed in this work to achieve the stabilization and sanitization of the concentrated domestic bio-wastes (CDBWs). Parasite eggs were not detected in the third-chamber effluents during different hydraulic retention time and temperature. With the packing unit, the second-chamber made some contributions to remove parasite eggs. The concentration level of faecal coliforms in the third-chamber effluents had met the limited level of WHO guidelines resulting from the lower pH and the higher concentrations of volatile fatty acids in the tank. An average of 27.4% of organic matter were converted into CH4 under different operating conditions, which resulted in the annual emissions of about 0.1 tonne CO2 equivalents per capital. The third-chamber effluents contained rich macro and trace elements and were suggested to replace some chemical fertilizers. With simple structure, easy operation and low cost, applying HRDT to sanitize and stabilize CDBWs requires a volume of 0.25 m(3)/cap, the vacuum source-separating sanitation system proposed in this study will be an efficient sanitation system integrated with sustainable agriculture. |
