Treatment of a steel works effluent with a conventional single-sludge system built in cascades
- Technical Univ. of Braunschweig (Germany). Dept. of Sanitary Engineering
Wastewater from steel producing plants or from cokery facilities contains a lot of substances like phenols or cyanides which need to be degraded. The requirements on the effluent quality have increased during the last years. Besides the elimination of the organic pollutants, of free cyanide, and of heavy metals, low concentrations of inorganic nitrogen in the effluent are required. Besides the elimination of the pollutants, the security in performance is an important requirement for a wastewater treatment plant treating steel works effluent. In this study, the authors concentrated on the treatment of the complete wastewater stream of a steel work instead of cleaning single streams in order to minimize high peak concentrations of inhibitory substances in the influent. Moreover, wastewater from diffuse sources is gathered and lead to the complete stream and these pollutants are treated as well. Treatment was achieved in a single-sludge system built in cascades. Because of the very low nitrogen concentrations in the effluent required by the controlling authorities, a post-denitrification step was mandatory. The only choices were a single-sludge or at least a three-sludge system. Of these, the first one was favored.
