The invention discloses an environment-friendly baking-free brick prepared from sludge and furnace slag. Raw materials include: sludge, domestic incinerator slag, cement, a curing agent and water in amass ratio of (35-40): (10-15): (40-50): (5-10). The preparation method comprises the following steps: carrying out pyrohydrolysis and thermophilic anaerobic digestion treatment on raw sludge, and dehydrating to obtain dehydrated sludge; adding a deodorant into the dehydrated sludge, naturally deodorizing and airing, then crushing, sieving with a 100-mesh sieve to obtain sludge powder, and sieving the domestic incinerator slag with a 50-mesh sieve to obtain slag particles; and mixing the sludge powder and the slag particles with Portland cement, a curing agent and water, putting the obtainedmixture into a mold, performing extrusion and compression molding, and performing maintenance in air so as to obtain the environment-friendly baking-free brick. Waste sludge and furnace slag can be used as raw materials to prepare the environment-friendly baking-free brick which is stable in property, free of pollution and capable of meeting the strength requirement.
本发明公开了一种利用污泥和炉渣制备的环保免烧砖，原料包括：污泥、生活垃圾焚烧炉渣、水泥、固化剂和水，按质量比计，污泥︰生活垃圾焚烧炉渣︰水泥︰固化剂为35～40︰10～15︰40～50︰5～10。制备方法为：将原生污泥经热水解、高温厌氧消化处理后进行脱水，得脱水污泥；向脱水污泥加入除臭剂，进行自然除臭和晾干，然后破碎，过100目筛，得污泥粉末，将生活垃圾焚烧炉渣过50目筛，得炉渣颗粒；将污泥粉末和炉渣颗粒与硅酸盐水泥、固化剂及水混合，所得混合物放入模具中，进行挤压、压制成型，于空气中养护，即得环保免烧砖。本发明能利用废料污泥和炉渣作为原料制备性质稳定、无污染、强度能满足需求的环保免烧砖。
