Sludge dredging environment-friendly improver and preparation method thereof
The invention belongs to the field of sludge treatment, and particularly relates to a sludge dredging environment-friendly improver and a preparation method thereof. The improver is mainly composed ofattapulgite, calcium superphosphate, biochemical fulvic acid, semi-hydrated gypsum, superfine slag powder, cement and an excitant. The sludge improver prepared by the invention is easily available inraw materials, simple to prepare, convenient to transport, simple to construct, green and environment-friendly, does not need to perform early-stage mechanical dehydration on dredged sludge, avoids the use of special sites and dehydration machinery, realizes resource recycling of industrial solid wastes such as superfine slag powder in the raw materials, and conforms to the ecological environmental protection concept of treating wastes with processes of wastes against one another. The improved soil is weakly alkaline and contains a certain amount of nutrients, ecological green improvement ofdredged silt to a green planting base is achieved, and the planting base supply requirements for slope engineering, roadbed engineering and municipal greening are met. The invention makes a great contribution to promotion of solid waste harmlessness and environment friendliness, and generates good economic benefits, social benefits and environmental benefits.
本发明属于淤泥处理领域，具体涉及一种疏浚淤泥绿色环保改良剂及其制备方法。所述改良剂主要由凹凸棒土、过磷酸钙、生化黄腐酸、半水石膏、矿渣微粉、水泥和激发剂组成。本发明制得的淤泥改良剂原料易得、制备简易、运输便捷、施工简单、绿色环保，无需对疏浚淤泥进行前期机械脱水，避免使用专门的场地和脱水机械，原料中含矿渣微粉等工业固体废弃物，实现资源化再生利用，符合以废治废生态环保理念。改良后土壤呈弱碱性，土壤中含有一定量养分，实现了疏浚淤泥向绿色种植基的生态化绿色改良，满足了对边坡工程、路基工程和市政绿化的种植基供应需求，对促进固废无害化、环境绿色化做出了巨大的贡献，产生了良好的经济效益、社会效益和环境效益。
