The invention discloses an environment-friendly brick based on municipal sludge. The environment-friendly brick is prepared from the following raw materials in parts by weight: municipal sludge, quicklime, building solid waste crushed powder, macadam, fine sand, phytase, plant enzymes, zymophyte, 425# composite Portland cement, a liquid additive, water, a disinfectant and elm powder. The invention further provides a preparation method of the environment-friendly brick based on municipal sludge. During preparation, the sludge is heavy in peculiar smell and rich in harmful bacteria, the quick lime is added firstly, then the municipal sludge is added and stirred, then the plant enzymes and the zymophyte are added and stirred, digestion, disinfection and deodorization treatment is conducted in a high-speed stirring and rolling bin, the sludge can serve as a raw material to be proportioned after treatment is completed, sludge gravel is stirred for 2 minutes, then the cement is added and stirred, finally, the liquid admixture is added and stirred, and pressing can be achieved. The surface of a formed product is free of obvious cracks, the structure is compact, the appearance meets the production standard, and the compression resistance is 17.5 MP.
本申请公开了一种基于市政污泥的环保砖，其原料按重量份包括：市政污泥、生石灰、建筑固废破碎粉状物及碎石、细砂、植酸酶、植物酵素、发酵菌、425#复合硅酸盐水泥、液态外掺剂、水、消毒剂、榆木粉。本发明还提出一种基于市政污泥的环保砖的制备方法。本发明在制备时，政污泥异味重且有害细菌多，首先加入生石灰再加入的市政污泥搅拌，再加植物酵素、发酵菌搅拌，在高速搅拌碾压仓中做消解、消毒、除臭处理，待处理完成后方可作为原料进行配比。先将污泥碎石搅拌2分钟，再加入水泥搅拌，最后加入液态外掺剂搅拌即可压制，成型后产品表面无明显裂纹，结构紧密，外观符合生产标准，抗压性能为17.5MP。
