Ecological concrete material for pore-forming through activated sludge fermentation and preparation method of ecological concrete material
The invention discloses an ecological concrete material for pore forming through activated sludge fermentation and a preparation method thereof, and belongs to the technical field of pervious concrete. The ecological concrete material is formed by compounding coarse aggregate, cement, activated sludge, water and a high-efficiency water reducing agent, the content of biodegradable organic matter components in the activated sludge is 7.0%, the content of sulfur dioxide is 25.0%, the total amount of microorganisms is 8.0 * 10 < 13 >/g, and the water content is 85.0%; ordinary Portland cement clinker in ecological concrete raw materials is replaced with activated sludge in equal mass, inorganic components in the activated sludge replace part of cement, organic components in the activated sludge serve as substrates for biological fermentation pore forming, microbial fermentation generates gas and foams to form the ecological concrete with a larger specific surface area, more microbial populations can be attached, and the ecological concrete has a higher specific surface area. And the capability of continuously, accurately and deeply treating initial rainwater pollutants is enhanced. The material provided by the invention has higher strength and larger specific surface area, and can realize recycling, harmlessness and low-carbon treatment of sludge.
本发明公开了一种利用活性污泥发酵造孔的生态混凝土材料及其制备方法，属于透水混凝土技术领域；所述生态混凝土材料由粗骨料、水泥、活性污泥、水和高效减水剂复合而成，其中，活性污泥中可生物降解的有机物组分含量为7.0%，二氧化硫含量为25.0%，微生物总量为8.0×1013个/克，含水率为85.0%；将生态混凝土原料中的普通硅酸盐水泥熟料等质量替换为活性污泥，以活性污泥中无机成分替代部分水泥，活性污泥中有机成分作为生物发酵造孔的底物，微生物发酵产气发泡形成更大比表面的生态混凝土，能够附着更多微生物种群，强化了持续精确和深度处理初期雨水污染物的能力。本发明材料具有更高强度、更大的比表面积，能够实现污泥的资源化、无害化和低碳化处理。
