摘要: 从环境建设的可持续发展出发 ,结合天津开发区在基础设施及园林绿化建设中面临土源紧缺以及周边地区存在大量的海湾泥、粉煤灰、碱渣土等固体废弃物的现实 ,在详细研究了3种废物的物理、化学性质的基础上探讨了用这些废物代替农田客土的可行性。实验及推广应用结果表明 ,这些废物按适当比例混合后能够形成一种可替代种植客土的新型土壤 ,这种新型土壤的最佳配比(即海湾泥与粉煤灰或碱渣土 )比例为3:1 ,同时该配比基质对植物生长的适宜性优于滨海盐土。

关键词: 固体废弃物, 新土源, 海湾泥, 碱渣土, 粉煤灰

Abstract: Aiming at the status qua of the shortage of soils suitable for landscaping construction in TEDA,the demands for sustainable development of the environmental construction and the existence of large quantities of three solid wastes (ooze,alkaline slag, coal ash) in coastal zone of Tianjin,their physical and chemical properties were studied in detail. Based upon which,the feasibilities of replacing earth brought in from elsewhere with the wastes are discussed. The results of experiments and popularization demonstrated that they could be developed into a new type of soil and substitute the earth brought in from elsewhere. They also showed that the most feasible proportion of mixing sea silt to alkaline slag or coal ash is 3:1,and besides,which is superior to sea shore saline soil in plant growth.

Key words: solid wastes, new soil, sea silt soil, alkaline slag, coal ash
