粉煤灰的理化特征及其综合利用

Physicochemical Features and Comprehensive Utilization on Fly-ash

粉煤灰是火电厂排出的固体废物，全国年产生量达１亿ｔ以上。目前我国对粉煤灰的利用率还比较低，粉煤灰大部分在贮灰场堆放，这不仅造成环境污染，也使资源大大浪费。解决粉煤灰污染的最佳办法是进行综合利用。

Fly-ash is a main solid waste of electirc plants.The annual production of fly-ash is over 0.1 billion tonnes in our country.At present,the utilization ratio of fly-ash is rather low yet,and most fly-ash has been deposited in storage areas.Not only has the environment been polluted by fly-ash,but also the resources have been wasted greatly.The comprehensive utilization is the best way solving flyash pollution.This paper introduces information on physicochemical features and comprehensive utilization of fly-ash.
