摘　　要：文章调查分析了泰安第一污水处理厂污泥好氧发酵工程增加污泥深度脱水系统前后各单元的电耗、物耗及能耗成本。结果表明,深度脱水前后污泥好氧发酵工程的吨泥电耗分别为101.24、97.26 kW·h/t湿污泥,从用电设备能耗情况来看,风机是城市污泥好氧发酵工程的主要能耗点,是节能降耗的重点;污泥深度脱水后,物耗虽增加了污泥调理剂,但无需再添加辅料,从使用量及成本而言,物耗呈下降趋势;吨泥能耗总成本从135.7元下降至65.5元,大幅下降了51.7%。因此,采用深度脱水作为污泥好氧发酵前处理技术,有利于节能降耗。This paper researches and analyzes the cost of each unit's electricity consumption,material consumption and energy consumption before and after the addition of the sludge deep dehydration system of the sludge aerobic fermentation project of the first sewage treatment plant in Taian.The results show that the power consumption per ton of sludge fermentation project before and after deep dehydration is 101.24 and 97.26 kW·h/t respectively.From the situation of energy consumption of electric equipment,the fan is the main energy consumption of the urban sludge aerobic fermentation project,and the focus of energy saving and consumption reducing.After deep dehydration,although material consumption increases sludge conditioner,it has no necessity to add auxiliary materials.In terms of the amount used and cost,the material consumption has been on decline.The total cost of energy consumption per ton of sludge decreases from 135.7 yuan to 65.5 yuan,with a significant drop of 51.7%.Therefore,the adoption of deep dehydration,as the pretreatment technology of sludge aerobic fermentation,is beneficial to energy saving and consumption reduction.
