Description
技术领域
本发明涉及环境保护技术领域,特别是固废资源化利用方法,具体是一种含藻泥、污泥和淤泥高有机物的人造轻集料及其制备方法。
背景技术
太湖蓝藻通过打捞船、吸藻泵等工具打捞蓝藻后,就近运输至藻水分离站,将藻浆体积缩小十余倍至数十倍后,产生的含水率75%-85%的性状即为蓝藻藻泥,太湖藻泥和清淤后的淤泥堆置造成的场地紧张、场地使用费用上涨等现象,已成为影响进一步太湖治理工程效率和经济性的重要因素,同时,刚疏浚后的淤泥的含水率(整个太湖范围淤泥含水率差异较大,但高有机质含量的新鲜淤泥含水率可达80%甚至90%以上)也较高,在后续消纳和利用前,需进一步调理脱水。因此,藻泥和淤泥资源化利用也是亟待解决的问题,已成为太湖治理及资源综合利用的重要研究方向。
随着建筑墙体材料朝着节能、节土、利废、保护环境和改善建筑功能的方向发展。传统隔墙材料耗费大量不可再生资源并带来严重的污染问题,以水泥为胶凝料和轻集料作为芯材制成复合建材,这些复合建材综合了保温砂浆、保温砌块以及EPS板的各种优异性能,改进了轻质节能墙体材料性能。密度很小的轻集料而言,采用传统的搅拌方式存在有上浮,成型后骨料不均匀分布等诸多问题,芯材的各项性能不能充分发挥,所用骨料比例仍然较低,墙体密度仍然偏大,不利于提高保温隔热功能。
发明内容
发明目的:本发明所要解决的技术问题是针对现有技术的不足,将藻泥、污泥、以及从淤泥中提取出高有机物作为原料,来制备满足工程技术要求的轻集料,同时为藻泥、污泥、淤泥的资源化利用提供新的思路。
为了解决上述技术问题,本发明采取的技术方案如下:
一种含藻泥、污泥和淤泥高有机物的轻集料,包括如下质量份的原料:
太湖藻泥干基物5~10份;
从河底或湖底淤泥中分离出的高有机物干基物65~75份;
生化污泥干基物3~5份;
Fe2O3 2~4份;
MgO 1~3份;
CaO 1~3份;
园林绿化废弃物1~3份。
藻泥和分离后淤泥高有机物用于制备轻集料,藻泥、生化污泥和淤泥高有机物的特性,焙烧后有机物分解,有机物的有机质含量超过20%,陶粒的膨胀系数达到2.5以上,有利于降低骨料密度,产生多孔,基于此解决了轻集料膨胀率差和骨料密度较大等问题,原料中原料废弃物烧制后,生成轻集料多孔轻质,同时园林废弃物具备一定燃烧热值,轻集料的生料焙烧时候,可以满足一定程度的自持燃烧,降低烧制过程的能耗,综上,本发明的配方生成轻集料解决了轻集料膨胀率差和骨料密度较大,有利于提升轻集料的保温节能、隔音降噪等性能并降低工程造价。
具体地,所述太湖藻泥为太湖藻水分离站处理后含水量为82~86 wt%的藻泥。
所述从河底或湖底淤泥中分离出的高有机物,为通过绞吸式或抓斗式清淤方式直接通过水力旋流器进行分级处理得到粒径小于63 μm的高有机物,经过板框压滤机械脱水至含水率为55~65 wt%,有机质含量40 wt%以上。
所述生化污泥为市政污水厂的生化污泥,通过机械脱水至含水率为80~85 wt%,有机质含量45 wt%以上。
所述园林废弃物需经粉碎处理,粉碎至粒径5~15mm。
本发明还提供上述轻集料的制备方法:
(1)将所述原料按配比混合,过100目筛后和适量水半湿研磨造粒,制成含水量为38~45wt%的生料球粒径为10~30mm;
(2)将步骤(1)所得生料球进行干燥;
(3)干燥好的生料球于1110~1150℃下焙烧10~20 min,然后随炉冷却至室温即得。
藻泥、污泥和淤泥其主要化学成分为SiO2、Al2O3等氧化物和有机物为主体材料(生产过程中用量不低于80%),将它们置于1000℃左右环境下焙烧,其中的SiO2、Al2O3与基料共同烧结会形成结构骨架提供强度,且其富含的有机质在烧成过程中则会分解产生气体,促进骨料膨胀,有利于降低骨料密度,生成有利于提升陶粒的保温节能、隔音降噪等性能。
本发明制备的含藻泥、污泥和淤泥高有机物的轻集料等级为400~500,筒压强度大于1.5MPa,软化系数不小于0.8,膨胀系数大于3.0。
本发明的创新性如下:(1)首次将藻泥和分离后淤泥高有机物用于制备轻集料,藻泥、生化污泥和淤泥高有机物的特性,焙烧后有机物分解,产生多孔,基于此解决了轻集料膨胀率差等问题;(2)确定了藻泥、高有机物的淤泥和生化污泥制备轻集料的配方,配方就地取材,实现废物的资源化利用;(3)所得轻集料可广泛应用于复合墙板、装配式墙板、砖、砌块等传统建材中,解决了大宗建筑材料原料不可再生来源紧张的问题。
本发明具有以下效果:(1)藻泥和淤泥相结合制备轻集料,其特点因地制宜、就地取材、废弃物资源化利用,具有良好经济效益和环境效益;(2)轻集料与制备适用性建材相结合,满足施工中多方面的需求;(3)原料材有高有机物促进轻集料膨胀,加入有机物的有机质含量超过30%,轻集料膨胀系数达到3.0以上,有利于提升轻集料的膨胀性能,生成建材有利于提升保温节能、隔音降噪等性能并降低工程造价。
