Photocatalytic water permeable brick based on ferrotungsten tailings and preparation method of photocatalytic water permeable brick
The invention provides a photocatalytic water permeable brick based on ferrotungsten tailings and a preparation method of the photocatalytic water permeable brick. The photocatalytic water permeable brick based on the ferrotungsten tailings comprises a photocatalytic surface layer and a matrix layer, the photocatalytic surface layer and the matrix layer are pressed into an integrated structure, and the photocatalytic surface layer is prepared from inorganic solid waste particles, tungsten tailing fine particles, iron tailing fine particles, silicate cement and fly ash; and the matrix layer is prepared from silicate cement, quartz sand, water gravel, desulfurized fly ash, clay, fly ash and a water reducing agent. On one hand, the problem of perennial accumulation of solid wastes is solved, and meanwhile, the utilization rate of the solid wastes is increased; on the other hand, the water permeable brick prepared from the tungsten tailings and the iron tailings generates a strong oxidation effect under illumination, toxic pollutants difficult to decompose in the air can be oxidized into inorganic substances such as CO2 and H2O, the water permeable brick has the advantages of being high in decomposition speed, high in cleaning degree, free of secondary pollution and the like, and the self-cleaning water permeable brick prepared by utilizing the characteristics has a certain environment-friendly advantage.
本发明提出了一种基于钨铁尾矿的光催化透水砖及其制备方法。所述基于钨铁尾矿的光催化透水砖包括光催化面层和基体层，光催化面层和基体层压制成一体结构，所述光催化面层由无机固体废料颗粒、钨尾矿细颗粒、铁尾矿细颗粒、硅酸水泥和粉煤灰制成；所述基体层由硅酸水泥、石英砂、水碎石、脱硫灰、粘土、粉煤灰和减水剂制成。本发明一方面解决了固体废弃物常年堆积的问题，同时提高了固体废弃物的利用率；另一方面利用钨尾矿和铁尾矿制成的透水砖，在光照下产生强烈的氧化作用，能把空气中难分解的有毒污染物氧化为CO2、H2O等无机物，具有分解速度快、除净度高、无二次污染等优点，利用其特点制成的自清洁透水砖，有一定的环保优势。
