In order to stabilize and recycle municipal solid waste incineration fly ashes,chemicaltabilization with copperas as agent was firstly applied and then the treated fly ash was solidified by mixing with cement,the resulted concrete blocks are save and strong enough to be used in some special cases.

为实现垃圾焚烧飞灰的无害化和资源化，先将绿矾溶液与飞灰混合后氧化稳定飞灰中的重金属，然后将处理后的飞灰与水泥混合、养护，使焚烧飞灰在双重稳定化的同时，得到的水泥砌块浸出浓度低，具有相当的强度，可以在特殊场合安全利用。

In order to determine the optimal conditions of water glass from oil shale ash, through orthogonal experiment, the influences of correlative parameters including NaOH concentration, material ratio (NaOH to oil shale ash in weight), reaction time and reaction temperature on the modulus of water glass or deliquescent rate of SiO2 were all studied.

为研究页岩灰制取水玻璃的最佳条件，分别以水玻璃模数和页岩灰中SiO2溶出率为指标，NaOH溶液质量分数、物料比（NaOH溶液与页岩灰的质量比）、碱浸时间和碱浸温度为影响因素。进行了正交试验。

This paper introduces the current methods to treat solid wastes abroad such as cement solidification, fly ash thermo-treatment, chemical solidification, chemical lixiviation and so on.

Generally, the amount of coal fly ash is four times of coal bottom ash, therefore, it needs more techniques to reutilize.

煤灰可分为底灰及飞灰二大类，其中飞灰产量约为底灰的四倍，因此需更积极寻求飞灰多方面之用途，以提升飞灰之利用量。

The results indicate that the mass size distribution of fly-ash particles in the inlet of the WFGD system is typically disturbed bimodally, the peaks are approximate at 1 and 3 μm. And the shape of particles is regular sphericity, the mass ratio of PM2.5 to PM10 is about 0.434. The total mass concentration is about 85 mg/m3. In the outlet of the WFGD system, the mass size distribution of fly-ash particles is also bimodal. The proportion of fine particles increased, the mass ratio of PM2.5 to PM10 is about 0.764. Some fine particles are conglutinated and formed irregular agglomerate. The total mass concentration is under 23 mg/m3, the removal efficiency of total particles is 74.5%. The size removal efficiency is decreased observably with the range of particle size decreasing.

结果表明，WFGD系统入口飞灰质量粒径呈典型的双峰分布，峰值分别在1和3 mm处，颗粒多呈规则球形，PM2.5与PM10质量比为0.434，飞灰总浓度约为85 mg/m3标准状态；出口处飞灰质量粒径分布也呈现双峰性，其中细颗粒比例增大，PM2.5与PM10质量比为0.764，细颗粒间相互聚集粘连形成不规则的块状结构，飞灰总浓度在23 mg/m3以下，总飞灰的脱除效率为74.5%，分级脱除效率随粒径减小而明显下降。
