Utilization of Energy and Growth of Aquatic Worms during the Process of Sludge Reduction by Aquatic Worms

Abstract:

In the research, the dissolved oxygen, energy efficiency index, growth of aquatic worms and sludge reduction were determined and analyzed. The energy use of aeration and the growth of aquatic worms were investigated during the process of in-situ sludge reduction by aquatic worms. For the wastewater treatment system adding with adequate aquatic worms, the power consumption was not increased and the utilization rate of oxygen was improved. The growth of aquatic worms well fitted DoseResp function and the sludge production was reduced evidently. Results indicate that the wastewater treatment adding with aquatic worms utilizes aeration energy sufficiently and reduces sludge production effectively.
