Method for preparing iron correction material from sludge ash and iron-rich industrial waste
The invention discloses a method for preparing an iron correction material from sludge ash and iron-rich industrial waste, and belongs to the field of environmental protection. The invention disclosesthe method for preparing the iron correction material from the sludge ash and the iron-rich industrial waste. The method comprises the following technological processes and steps: fully stirring andmixing the sludge ash, the iron-rich industrial waste, a binder and other raw and auxiliary materials in a mixer according to a corresponding ratio to obtain a mixture called as a pelletizing base material after indexes such as water content, iron content, chloride ions, sulfur trioxide, magnesium oxide, granularity, viscosity and the like meet pelletizing requirements, and forcibly pressurizing the pelletizing base material in a hydraulic medium-pressure ball press machine to obtain the product iron correction material; the method provided by the invention can be used for preparing the cementiron correction material from the sludge ash and the iron-rich industrial waste which are obtained after incineration of a sludge treatment plant, and the method provided by the invention can be usedfor realizing resource treatment and utilization of the sludge ash and the iron-rich industrial waste.
本发明公开了一种利用污泥灰渣和富铁工业废料制备铁质校正料的方法，属于环保领域。本发明一种利用污泥灰渣和富铁工业废料制备铁质校正料的方法，具有以下的工艺过程和步骤，将污泥灰渣、富铁工业废料、粘结剂等原辅料按相应比例在混合机内进行充分搅拌混合，含水率、含铁量、氯离子、三氧化硫、氧化镁、粒度、粘度等指标达到成球要求后称为成球基料，将所述成球基料在液压型中压压球机内经强制加压成产品铁质校正料，本发明提供的方法能够将污泥处理厂焚烧后得到的污泥灰渣和富铁工业废物制备成水泥铁质校正料，本发明提供的方法可实现污泥灰渣和富铁工业废料的资源化处置利用。
