As a 'green' technology with low energy consumption, reed bed systems have become popular in recent years for the treatment of a variety of effluents. However, when they are used to treat effluents with high BOD and NH4-N levels their efficacy is often limited by shortage of oxygen supply and poor water distribution. In order to overcome these problems, the concept of 'tidal flow' is introduced to create a new reed bed system where the bed matrix is alternately filled with wastewater and then drained. Such tidal flow operation enables the available matrix to be fully utilized, eliminating the problem of poor water distribution associated with conventional downflow reed beds. The rhythmical 'tides' generated in tidal flow systems repeatedly draw air from the atmosphere into the reed bed matrix, thus considerably improving the aeration of the matrix, enabling more pollutants to be aerobically decomposed. Preliminary studies on tidal flow systems have produced promising results. In the proposed project, trials will be carried out to determine the appropriate operating conditions for these systems. The mechanisms and kinetics for the reductions of some major pollutants will be investigated in both laboratoryand full-scale experiments. The relationships between operating parameters, pollutant loadings and pollutant removal rates will be studied, and simple models will be established for design purposes.
