Design and Operation Analysis of Qingpu Sludge Drying and Incineration Project
摘要
Abstract
The sludge drying and incineration phase Ⅰ project of Qingpu District is designed to treat 300 t/d dewatered sludge(80％moisture content)from ten wastewater treatment plants in Qingpu.The project adopted"film drying+bubbling fluidized bed incinerator"treatment process,built two sludge drying incineration lines.The waste incineration boiler was used to recycle the heat of sludge incineration to generate steam,the steam was used to dry the sludge.Flue gas treatment adopted"desulphurization(in-furnace)+selective non-catdytic reduction(SNCR)(in-furnace)+electrostatic precipitation+dry reactor+activated carbon injection+bag dust removal+wet deacidification+reheater process".The odor was treated by combinations process of source closed,classified collection,classification control and multi-method treatment.Mixed wastewater and deacidification wastewater by classified collection and classification treatment was treated.The whole project overcomes the difficulties of similar sludge projects that constructed isolatedly,operates stably,performance of pollutant control is excellent.It has certain reference value for other similar projects.关键词
