Abstract
Description
- в сток, прошедший решетки и песколовки, в качестве сорбентов вносят подвергнутый пиролизу и измельченный до пылевидного состояния осадок сточных вод, а также катионный флокулянт, обеспечивающий ускорение отделения стоков от нерастворимых примесей, а также способствующий снижению сопротивления влагоотдаче осадков при их механическом обезвоживании,
- отстоянный сток подвергают биологической доочистке в двухступенчатом биореакторе, первая ступень которого является нитри-денитрификатором, снабженным рециркуляцией очищаемой сточной жидкости с выхода на вход ступени и плавающими контейнерами с ершовой насадкой для удержания и фиксации в пространстве микроорганизмов, очищающих сточную жидкость от органических и минеральных веществ,
- дозирование модифицированных пиролизом осадков сточных вод осуществляют прямо пропорционально наличию растворенных органических веществ в исходном стоке и обратно пропорционально наличию азота аммонийного, подлежащего удалению нитри-денитрификацией.
