Abstract
Изобретение относится к способам дефосфатации сточных вод, в частности сточных вод образующихся на животноводческих фермах.Способ, согласно изобретению, включает обработку вод коагулирующе-осаждающим агентом, коагуляцию-осаждение фосфатов и их выделение путём фильтрации, при этом в качестве коагулирующе-осаждающего агента используют дефекат сахарного производства, взятого в соотношении в пересчёте на содержание кальция по отношению к содержанию фосфора в сточных водах (5…7):1.
