摘要
以某电厂灰渣作为研究对象,分别对锅炉渣、粉煤灰和烟道灰3种材料对水环境的影响进行了试验,全面分析了灰渣的物理性质和化学成分。分别做了灰渣的浸出毒性试验、浸出剂的pH值对粉煤灰重金属浸出毒性试验,灰渣的腐蚀性、灰渣的淋溶、灰渣的沉降试验,从而得出燃煤电厂固体废物对水环境潜在的毒性影响。
The potential impact of solid wastes such as boiler residue, powder coal ash and flue ash on water environment were examined on the basis of a serial of tests. Phsical properties and chemical composition of solid wastes were analysed systematically. The extraetion toxicity test and the pH of lixiviated agent to the metal concentration test were carried out, as well as corrosion test, settement test, eluviating test of solid wastes. It can be predicated that there is potential effect of solid wastes in coal - fired power plant on water environment.
