Sammanfattning

Common physicochemical treatment of industrial wastewater is not very efficient regarding the removal of the oxyanion forming elements selenium, molybdenum and antimony. An industrial case is described where effluents from the wet treatment of flue gases from a rotary kiln for the incineration of industrial waste, contain variable amounts of the elements mentioned. The effluent of the scrubbers is neutralized, coagulated and flocculated. Mercury is removed by precipitation with TMT. The installation shows satisfactory results, complying with the regulations for common cations. The effluent of the settling tank still contains variable concentrations of selenium, molybdenum and antimony and the overall removal efficiency is not reproducible for these elements. Laboratory experiments are presented for the removal by co-precipitation and the results are discussed. Possible treatment methods are selected and evaluated in a matrix that may help in the selection of methods for the simultaneous removal of oxyanion forming elements.
