摘要
针对污泥处理量为250t/d的城市污泥深度脱水-热干化-焚烧系统进行技术经济性分析,获得了污泥干基热值、深度脱水污泥含水率及热干化污泥含水率等主要参数对系统投资成本、运行成本及效益的影响规律,并寻求了最优方案。结果表明:污泥干基热值对系统投资成本影响最大;焚烧系统产汽量不能满足污泥热干化所需时,系统效益迅速降低。
Based on economic analysis of a dewatering, thermal drying and incineration system with a dealing capacity of 250 t/d for municipal sludge, the effects of following factors on the investment cost, operation cost and the system efficiency were studied, such as the dry basis calorific value of original sludge, the moisture content of deeply or thermally dried sludge, and so on, after which, an optimal scheme was obtained. Results show that the dry basis calorific value of sludge has the greatest influence on the investment cost of the system; the system efficiency decreases rapidly when the amount of steam produced by the incineration system cannot meet the requirement of sludge thermal drying.
