Gypsum block
The invention discloses a preparation method for sludge ash. The preparation method comprises the following steps: 1) drying sludge, conducting calcining at a high temperature, and performing rapid cooling; and 2) crushing the cooled sludge to obtain the sludge ash. The invention further discloses a gypsum block. The gypsum block comprises the sludge ash. The sludge ash is added into a formula for the gypsum block, so comprehensive utilization of sludge solid waste is facilitated, and the purposes of effectively utilizing resources and comprehensively treating environmental pollution are achieved. Meanwhile, the building block has excellent strength. The added sludge ash and used desulfurized gypsum, phosphogypsum and titanium gypsum clinker are economical and environmentally friendly, pollution of solid waste to the environment is reduced, and recycling of the solid waste is facilitated.
本申请公开了一种污泥灰的制备方法，包括以下步骤：1)将污泥烘干后高温煅烧，然后急速冷却；2)冷却后的所述污泥经粉碎即得所述污泥灰。还公开了一种石膏砌块，所述石膏砌块中包括该污泥灰。石膏砌块配方中加入污泥灰，有利于污泥固体废弃物的综合利用，达到有效利用资源，综合治理环境污染的目的。同时该砌块具有优异的强度。本申请中加入的污泥灰及使用的脱硫石膏、磷石膏和钛石膏熟料经济环保，减少了固体废物对环境的污染，有利于固体废物的循环利用。
