摘要

Process for treating an effluent (A) containing phosphorus and possibly nitrogen and / or organic materials and / or heavy metals, wherein: - is added a base (B) mainly to precipitate at least part of the phosphorus and possibly to volatilize a portion of the ammoniacal nitrogen in the form of gaseous ammonia and / or to precipitate at least part of the organic and / or heavy metal materials. - it becomes experience electroflocculation in the mixture of the effluent and the base (A + B) thus obtained in a cell equipped with electrodes electrofloculation iron; and - the flakes (F) formed during the electroflocculation and sludge (E) possibly present from the liquid phase (D) which constitutes the purified effluent are separated.
