摘要
以太原二电厂粉煤灰浸出试验为例,对火电厂粉煤灰长期堆放造成水环境污染的规律进行研究。试验结果表明:粉煤灰水中的酸碱性受灰中SO3与碱性金属氧化物含量的影响;粉煤灰浸出液pH值越低,越利于粉煤灰中微量元素的浸出;同时粉煤灰的粒径越小,各元素的浸出浓度较高。
On the basis of the fly ash＇s lixiviation test of the second power plant of Taiyuan, we study on the rules of the fly ash stored there has an effect on the water environment. The results indicate that the acidity and basicity in the waste water are affected by the SO3 and metal oxide content in the fly ash; the lower the value of pH in the waste water is, the more the trace element content＇ Ⅱ become; and the smaller the size of fly ash is, the higher the density of the waste water＇ Ⅱ become.
