Abstract
1. СПОСОБ ОБРАБОТКИ ИЗБЫТОЧНОГО АКТИВНОГО ИЛА, включающий его аэробную . стабилизацию, уплотнение, введение химического реагента, механическое обезвоживание, о -f л и ча .ющийс тем, что, с целью увеличени степени уплотнени , улучшени обезвоживани и удешевлени способа, в качестве химического реагента используют шлам от нейтрализации кисль1х сточных вод, который ввод т непосредственно перед уплотнением . 2.Способ по п. 1, отличающий с тем, что избыточный активный ил обрабатывают вместе с первичным осадком. 3.Способ по пп,1 и2, отличающийс тем, что шлам ввод т р Чо. KJ и -11 - 4. . -F-- В осадок в количестве 20-40% от массы Л сухого вещества осадка.1. METHOD FOR TREATING EXCESSIVE ACTIVE SILT, including its aerobic. stabilization, compaction, the introduction of a chemical reagent, mechanical dewatering, about -f l and some of the fact that, in order to increase the degree of compaction, improve the dewatering and reduce the cost of the process, sludge from neutralizing acidic wastewater is used as a chemical reagent, which just before compaction. 2. The method according to claim 1, characterized in that the excess activated sludge is treated together with the primary sludge. 3. A method according to claims 1 and 2, characterized in that the sludge is introduced into the pho. KJ and -11 - 4.. -F-- In the sediment in the amount of 20-40% by weight of L dry matter of the sediment
