biological wastewater treatment - Opis:
- The subject of research consists in a rotational biological contactor with a rotor characterized by a bi-directional longitudinal flow as an element of synchronized system of disposal and biological treatment of sanitary wastewater in small-bore sewerage. The rotor design is based on a system of corrugated protective pipes, arranged in coils wound around its rotation axis. The corrugated pipes have two purposes. On the one hand, they ensure and enable the aeration of activated sludge, and provide the surface for biofilm development on the other. The special winding of corrugated pipes enables a bi-directional flow of the liquid medium. During the rotation of the rotor, the RBC is simultaneously emptied and filled with wastewater. The structure of the rotational biological contactor aims to provide intensive aeration of the transported wastewater, which would allow for a greater development of microorganisms participating in the hybrid treatment of wastewater, i.e. the activated sludge method and by means of a trickling filter. Design solutions of the rotor pertaining to coil arrangement and the drive system were analyzed and tracer studies of hydrodynamics were performed in regard to the selection of appropriate structural parameters of the device. The obtained results indicate a clear influence of the design solution and its kinematics on the aeration time of the flowing medium, which is one of the parameters governing the efficiency and quality of RBC operation.
