| 摘 要： | 污泥处理及其处置所面临的重要问题之一，就是如何对城市污水处理厂产生的污泥进行有效减容，尽量降低对外部能源的需求。文中在掌握国内外污泥干化主要工艺技术的基础上，针对某城市污水处理厂的污泥干化工程，拟对采用燃煤烟气干燥、污泥消化一干化一体化、太阳能热泵干燥等三种不同污泥干化工艺进行物料、能量工艺核算。并在此基础上，计算初期投资与15年的运行费用总和。通过对燃料价格、环保和安全等影响因素的研究，分析比较了五种供热系统，以太阳能热泵供热系统为最优，值得大力推广和应用。

| Abstract: | One of the important issues of sludge treatment and disposal is how to reduce the sludge volume effectively,which is produced from the municipal sewage treatment plant,with low exterior energy demand as far as possible.This paper calculated energy demand of three kinds of different sludge dry crafts,such as flue gas from coal-fired dry,sludge digestion and dry integration,solar energy heat pump integration.Based on the above energy calculation,a comparative conclusion was drawn from the summation of initial... |
