Light ceramsite containing electrolytic manganese residues and preparation method thereof
The invention discloses a lightweight ceramsite containing electrolytic manganese residues and a preparation method thereof, the electrolytic manganese residues, dried sludge, a high-silicon aluminum iron material and bentonite are mixed, granulated and sintered at 1120-1150 DEG C to obtain the lightweight ceramsite, and the dried sludge is obtained by mixing sludge in a sewage plant and a drying agent. According to the method, a large amount of electrolytic manganese residues and sludge are consumed, stockpiling pressure and environmental pollution are relieved, meanwhile, the prepared lightweight ceramsite containing the electrolytic manganese residues has low stacking density, apparent density and balanced cylinder compressive strength, and meanwhile the exudation concentration of Mn < 2 + > is reduced and is lower than the requirement in GB3838-2002 Environmental Quality Standard for Surface Water.
本发明公开了一种含电解锰渣的轻质陶粒及其制备方法，将电解锰渣与干化污泥、高硅铝铁材料和膨润土混合、造粒，并在1120‑1150℃下烧结得到轻质陶粒，其中干化污泥由污水厂中的污泥与干化剂混合而得。本发明消耗了大量的电解锰渣和污泥，缓解了堆存压力和对环境的污染，同时制备得到含电解锰渣的轻质陶粒具有较低的堆积密度、表观密度、均衡的筒压强度，同时降低了Mn2+的渗出浓度，使其低于GB3838‑2002《地表水环境质量标准》中的要求。
