我国典型城市污泥产生量处理处置现状及经济学趋势分析

【摘要】 城市污泥已经成为各城市、全国乃至全世界亟待解决的问题。评述了城市污泥一般处理处置技术、国内外研究现状,以IGP方程为基础,分析我国1998—2017年城市干污泥产量及处理处置现状,并预测到2025年若不采取任何措施城市污泥仍会持续增加的发展趋势。随着我国对污泥农用重视度的提高,农用标准越来越完善,污泥填埋处理方式逐渐被淘汰,污泥的沙地利用逐渐兴盛。以我国8个一级城市为例,对其污泥利用现状进行比较。更多还原

【Abstract】 Municipal sewage sludge has been became an urgent problem in cities,the whole country and even the whole world. The general treatment and disposal technology of municipal sewage sludge and the current situation at home and abroad are reviewed. The present situation of municipal sewage sludge production and treatment in China from 1998 to 2017 is analyzed according to the IGP equation. It also predicted that the development trend will continue to increase until 2025 if no measures are taken. The sand use of sludge should be vigorously developed and landfill of sludge is gradually eliminated with the increase of emphasis on agricultural use of sludge and the improvement of agricultural use standards in our country. Eight first-class cities in China is selected to compare their sludge utilization status.更多还原
