摘要
In a sewage treatment system including an activated sludge tank and a reclarification tank, the sewage and the recycled sludge are introduced in fine distribution in the aeration zone into the sewage/activated sludge emulsion. The oxygen content in the latter is measured in an outflow to the reclarification basin and the aeration is controlled accordingly. This enables the mixing degree and the equilibrium between growth and flushing away of the microorganisms to be controlled to eliminate excessive sludge production. The better kinematic conditions for the reaction in the first phase results in a better efficiency. The specific throughput of a plant is thereby increased.
