Preparation method of iron tailing ceramsite filter material for wastewater treatment
The invention discloses a preparation method of an iron tailing ceramsite filter material for wastewater treatment. The iron tailing ceramsite filter material comprises the following raw materials in percentage by weight: 50.0%-73.0% of iron tailings, 10.0%-20.0% of a silicon-aluminum raw material, 15.0%-38.0% of a calcium-magnesium raw material and 2.0%-7.0% of a biomass raw material. The preparation method comprises the following steps: respectively drying the raw materials, respectively grinding the dried raw materials to-0.15 mm by adopting a mill, and then mixing the ground raw materials in a mixer to obtain a blank for later use; the blank is put into a pelletizer to be pelletized and formed, the pelletized and formed filter material is fired in a rotary kiln at the temperature of 1150-1250 DEG C, an iron tailing ceramic filter material product is obtained, the prepared iron tailing ceramic filter material completely meets the technical index requirements of CJ/T 299-2009 and can be used for treatment of mine wastewater, chemical wastewater and domestic wastewater, a new way is opened up for bulk utilization of iron tailings, and the iron tailing ceramic filter material is suitable for industrial production. And the effect of treating waste with waste is achieved. Wherein for treating the mine wastewater, local materials are used, local production and local application are realized, the links of time sequence and space sequence are saved, and remarkable economic, environmental and social benefits are achieved.
本发明公开了一种用于废水处理的铁尾矿陶粒滤料的制备方法,原料配比为：铁尾矿50.0％～73.0％、硅铝原料10.0％～20.0％、钙镁原料15.0％～38.0％，生物质原料2.0％～7.0％；将原料分别进行烘干后各自采用磨机碎磨至‑0.15mm,然后在混料机中混合得到坯料，备用；将坯料放入造球机进行造球成型，将造球成型的滤料在回转窑中于1150～1250℃烧制，得到铁尾矿陶瓷滤料产品，制备出铁尾矿陶瓷滤料完全满足CJ/T 299‑2009技术指标要求，可用于矿山废水、化工废水、生活废水处理，为铁尾矿大宗利用开辟一条新的途径，达到以废治废的成效。其中处理矿山废水上，更是就地取材，就地生产，就地应用，节约时序和空间序的环节，具有显著的经济、环境和社会效益。
