摘要
自来水和废水处理厂的污泥日益增长,如何经济有效地处置这些污泥已成为一个环境问题。本文分析了污泥的物理化学性能和毒性特征,探讨了利用粉煤灰共处置水厂干化污泥并用于轻质集料或陶粒、水泥混凝土、砖等土木工程材料,提出了目前亟需解决的一些关键技术问题,并明确指出利用粉煤灰处置污泥制备土木工程材料是我国污泥处置的有效途径。
What to do with the rapidly increasing drinking and wastes water treatment works sludge in an economic and environmentally sustainable manner remains a significant environmental issue. In this paper, the chemical and toxic properties of this sludge were analyzed. Using fly ash to utilize these sludge in civil engineering materials, including light aggregate or ceramic granule, concrete admixture and brick etc. were,explored and the advantages and challenges were also pointed out. It was confirmed that utilizing these sludge in civil engineering materials was an effective and important approach,
