Abstract
Способ просветления сточных вод прокатного производства включает улавливание крупнодисперсной окалины в первичном отстойнике и обезвоживание в бункере, подачу воды с остаточным содержанием окалины на вторичное просветление во вторичных отстойниках и обезвоживание крупнодисперсной замасленной окалины. Отношение количества уловленной окалины в первичном отстойнике к количеству уловленной замасленной окалины во вторичных горизонтальных отстойниках составляет ( 2,5-3,0 ) : 1, при этом просветление воды в первичном отстойнике осуществляют после пребывания очищающейся воды на протяжении 4-5 минут.
