実験手順

reacting said waste water with a mixture of calcium oxide and calcium sulfide and with recycled ammonium sulfite from step (f), the molar ratio CaS/CaO being at least 0.5:1 and the amounts of the reactants being sufficient to form simultaneously insoluble calcium sulfate, insoluble calcium sulfite, and ammonium sulfide dissolved in the aqueous phase and then separating the resulting mixture of insoluble calcium sulfate and calcium sulfite from the aqueous phase,
