河道淤泥基本性能及资源化利用的研究

:通过对浙江省宁波、台州、金华、湖州四地采集的河道淤泥进行化学成分、物相分析、重金属含量、粒径分布、发热量及塑性指数的测定来说明河道淤泥用于烧结砖及陶粒生产的可行性。结果表明,河道淤泥的基本理化性能满足生产烧结砖与陶粒的原料要求,均可用于生产烧结砖或陶粒。

Study on basic properties and resource utilization of river silt

This paper demonstrates the feasibility of using river silt for the production of fired bricks and ceramsite by measuring the chemical composition, phase analysis, heavy metal content, particle size distribution, calorific value and plasticity index of river silt collected in Ningbo, Taizhou, Jinhua and Huzhou in Zhejiang province. The results show that the basic physical and chemical properties of the river silt meet the raw material requirements for the production of fired bricks and ceramsite, and can be used to produce fired bricks or ceramsite.
