【摘要】：调查了上海松江和青岛小涧西两个城市污泥好氧发酵工程的电耗和油耗,并对工程的主要能耗点进行了识别。结果表明,上海松江和青岛小涧西两个城市污泥好氧发酵工程的电耗分别为66.1、38.2 k W·h/t湿污泥,油耗分别为1.16、2.01 L/t湿污泥。在物料混合、发酵、除臭等主要工艺环节中,除臭单元电耗占工程总电耗比例最大,上海松江工程和青岛小涧西工程中除臭单元电耗占整个污泥好氧发酵工程总电耗的比例分别为69.1%和66.8%,其次是发酵单元,混料单元最小。从用电设备能耗情况来看,曝气鼓风机和除臭离心风机是城市污泥好氧发酵工程的主要能耗点,这应是未来进行节能降耗的重点。
[Abstract]:The power consumption and oil consumption of sludge aerobic fermentation projects in Shanghai Songjiang and Qingdao Jianxi cities were investigated, and the main energy consumption points of the projects were identified. The power consumption and oil consumption of sludge aerobic fermentation project in Shanghai Songjiang city and Qingdao Jianxi city were 66.1 ~ 38.2 kW 路h / t and 1.16, respectively. 2.01 L / t wet sludge. In the main process of material mixing, fermentation and deodorization, the electricity consumption of deodorization unit accounts for the largest proportion of the total power consumption of the project. In Shanghai Songjiang Project and Qingdao small Jianxi Project, the proportion of electricity consumption of deodorization unit in the whole sludge aerobic fermentation project was 69.1% and 66.8 respectively, followed by the fermentation unit. From the point of view of the energy consumption of electric equipment aeration blower and deodorization centrifugal fan are the main energy consumption points of urban sludge aerobic fermentation project which should be the focus of energy saving and consumption reduction in the future.
