METHOD AND APPARATUS FOR BIO-PHYSICO-CHEMICAL CLEANING OF HIGH-TENSID CONCENTRATE ACIDS

摘要

The invention can be applied to the purification of all effluents arising in the manufacture and manufacture of household chemicals. The aim and object of the invention is to purify these effluents so that the energy input and the operating and system costs are reduced by interactions of the physical and biochemical Vorgenenge in the liquid phase and in the foam are generated, and the microorganism is subjected to appropriate conditions. The operating principle is to create a fluid-foam cycle whereby surfactants are foamed and mud is floated into the foam, intense microbial degradation and surfactant absorption is effected in the foam, and spent sludge with degraded and absorbed surfactants is flushed out of the foam again.
