Biomass sludge ceramsite as well as preparation method and application thereof
The invention discloses biomass sludge ceramsite and a preparation method and application thereof. The biomass sludge ceramsite is prepared from, by weight, 31.5%-37.5% of biomass raw materials, 10%-15% of fly ash and 47.5%-58.5% of absolute dry sludge, wherein the fly ash is Shell coal gasification fly ash formed by sintering at the high temperature of 1400-1600 DEG C. According to the biomass sludge ceramsite disclosed by the invention, the excess sludge of a sewage treatment plant, the biomass mixed combustion ash and the coal gasification fly ash are taken as raw materials, so that the problems of raw material sources and sludge treatment of the existing ceramsite can be effectively solved, and the Shell coal gasification fly ash is reasonably utilized. Moreover, the biomass sludge ceramsite prepared by the method is high in water absorption rate, high in cylinder compressive strength, low in breakage rate and loss rate, large in porosity and large in specific surface area when being used as a filter material for treating industrial wastewater, can achieve a relatively good adsorption effect, is pressure-resistant and not easy to break, and is suitable for treating the industrial wastewater.
本发明公开了一种一种生物质污泥陶粒、制备方法及应用，生物质污泥陶粒按重量百分比计，由以下原料组成：生物质原料31.5％～37.5％，粉煤灰10％～15％，绝干污泥47.5％～58.5％，所述粉煤灰为在1400～1600℃高温下烧结形成的Shell煤气化粉煤灰。本发明的生物质污泥陶粒以污水处理厂剩余污泥、生物质混烧灰、煤气化粉煤灰为原料，不仅可以有效地解决现有陶粒的原料来源问题，污泥处理问题，而且还使Shell煤气化粉煤灰得到了合理的利用。并且，本发明制备的生物质污泥陶粒，作为滤料处理工业废水吸水率高，筒压强度强，破碎率和损率低，孔隙率大、比表面积大，可以达到较好的吸附效果且耐压不易碎，适用于处理工业废水。
