PROCESSO PARA A PURIFICACAO E ELIMINACAO DE ODOR DE AGUAS RESIDUAIS QUE CONTEM COMPOSTOS ORGANICOS DE FOSFORO E ENXOFRE

The waste water is oxidised at a redox potential between 300 and 600 mV (measured with a platinum electrode relative to a silver-silver chloride electrode) at temperatures of from between 20 and 220 DEG C and at oxygen partial pressures of 1 to 10 bar in the presence of such amounts of iron(II) salt...

Zusammenfassung:The waste water is oxidised at a redox potential between 300 and 600 mV (measured with a platinum electrode relative to a silver-silver chloride electrode) at temperatures of from between 20 and 220 DEG C and at oxygen partial pressures of 1 to 10 bar in the presence of such amounts of iron(II) salt and optionally calcium ions that virtually the entire phosphorus present in the waste water is converted into solid iron(III) phosphate.
