技术领域technical field
本发明涉及一种污泥生物炭基的轻型长效屋顶绿化栽培基质及其制备方法。The invention relates to a sludge biochar-based light-duty long-acting roof greening cultivation substrate and a preparation method thereof.
背景技术Background technique
城市建筑越来越强调建筑与自然环境的协调，需要将更多的绿色空间引入到建筑中。屋顶绿化是以建筑物的顶部平台为依托营造园林景观的空间绿化形式，在降低扬尘、净化空气、缓解城市热岛效应方面产生了显著作用，同时还增加了城市绿化面积，节约城市用地，丰富了城市绿色景观。因此，屋顶绿化已经成为人口密集城市的建筑趋势。屋顶绿化作为区别于地面绿化的园林形式，在栽培基质选择上有特殊要求。考虑到减轻屋顶载荷，屋顶绿化栽培基质需要轻质；从屋顶排水方面考虑，基质颗粒不能太小，不能堵塞排水管道。 常规地面绿化栽培基质一般不具备上述两个方面的要求，因此，对于屋顶绿化栽培基质的研发成为亟待解决的技术难题。Urban architecture is increasingly emphasizing the coordination between buildings and the natural environment, and more green spaces need to be introduced into buildings. Roof greening is a space greening form based on the top platform of the building to create a garden landscape. It has played a significant role in reducing dust, purifying the air, and alleviating the urban heat island effect. At the same time, it also increases the urban greening area, saves urban land, and enriches Urban green landscape. Therefore, green roofs have become an architectural trend in densely populated cities. As a garden form different from ground greening, roof greening has special requirements for the selection of cultivation substrates. Considering the reduction of the roof load, the roof greening cultivation substrate needs to be light; in terms of roof drainage, the substrate particles should not be too small to block the drainage pipes. Conventional ground greening cultivation substrates generally do not meet the requirements of the above two aspects. Therefore, the research and development of roof greening cultivation substrates has become a technical problem to be solved urgently.
城市生活污泥是城市生活污水的处理过程中的沉淀物，它的处理处置问题一直是困扰城市发展的难题。目前，将城市生活污泥通过低温热裂解技术炭化制备成生物炭，成为城市生活污泥资源化利用的重要方式之一。轻质的污泥生物炭具有成为屋顶绿化栽培基质的潜质，然而，污泥生物炭基屋顶绿化栽培基质的研究却鲜见报道。Municipal domestic sludge is the sediment in the treatment process of urban domestic sewage, and its treatment and disposal has always been a problem that plagues urban development. At present, the carbonization of municipal domestic sludge into biochar by low-temperature pyrolysis technology has become one of the important ways of resource utilization of municipal domestic sludge. Lightweight sludge biochar has the potential to become a roof greening cultivation substrate, however, the research on sludge biochar-based roof greening cultivation substrate is rarely reported.
有研究者以城市生活污泥为材料作为屋顶绿化栽培基质做过相关的探索。申请号为201410464951.4和201010272600.5的专利均以城市生活污泥为主要原料，通过好氧堆肥工艺制备屋顶绿化栽培基质材料。污泥堆肥发酵后的产品虽具有较高的肥力，但作为屋顶绿化基质，容重依然较高，且颗粒遇水松散，极易造成下水管道堵塞。另外，好氧堆肥工艺控制不好的话，污泥堆肥产品病原菌杀灭不彻底，会侵染植物，污泥堆肥产品还会散发臭味，容易招诱虫鸟。Some researchers have made relevant explorations using urban domestic sludge as a material for roof greening cultivation. The patents with application numbers 201410464951.4 and 201010272600.5 both use urban domestic sludge as the main raw material, and prepare roof greening cultivation substrate materials through aerobic composting process. Although the fermented product of sludge composting has high fertility, as a green roof substrate, the bulk density is still high, and the particles are loose when exposed to water, which can easily cause blockage of sewer pipes. In addition, if the aerobic composting process is not well controlled, the pathogenic bacteria in the sludge composting products will not be completely killed, which will infect plants, and the sludge composting products will also emit odor, which is easy to attract insects and birds.
城市生活污泥生物炭是通过低温热裂解技术将污泥炭化后的产物，不同于常见的炭黑和活性炭，是一种新型的环境材料。该材料具有容重小、杀菌彻底、无异味、疏松多孔特点，另外，由于具有较高比表面积，污泥生物炭可作为肥料的缓释载体，且自身有机碳含量较高，同时，具有良好的保水保肥效果，完全具有栽培基质所需要的“水、肥、气、热”特征，能够发挥不是土壤却胜似土壤的作用。将污泥生物炭作为屋顶绿化的栽培基质，开辟了城市生活污泥资源化利用的新途径，具有重要的社会和生态意义。Municipal domestic sludge biochar is a product of sludge carbonization through low-temperature pyrolysis technology. It is different from common carbon black and activated carbon, and is a new type of environmental material. The material has the characteristics of small bulk density, thorough sterilization, no peculiar smell, loose and porous. In addition, due to its high specific surface area, sludge biochar can be used as a slow-release carrier for fertilizers, and its own organic carbon content is high. At the same time, it has good The effect of water and fertilizer preservation fully has the characteristics of "water, fertilizer, air and heat" required by the cultivation substrate, and can play a role that is not soil but better than soil. Using sludge biochar as the cultivation substrate of roof greening has opened up a new way of resource utilization of urban domestic sludge, which has important social and ecological significance.
