| Abstract: | The aim of the work has been to develop a biological treatment for chemical industry effluents. A multistage photosynthetic chemostat, fed by chemical industry effluents, was operated continuously as a bench scale experiment aimed at testing the possibility of treating these effluents by means of stabilization ponds. 70–80% of COD and 80–85% of BOD could be removed together with the pesticidal activity present in the raw wastewater. Optimal number of reactors was found to be 6. Most of the COD and BOD elimination took place during a 30 day detention time. The effluents cannot be considered suitable for free discharge, but can be disposed of by irrigating carefully a halotolerant vegetation. |
