Method for synergistically firing ceramsite by using river and lake bottom mud and municipal sludge
The invention relates to the technical field of municipal environmental engineering, in particular to a method for synergistically firing ceramsite by using river and lake bottom mud and municipal sludge. The method for firing the ceramsite comprises the following steps: respectively pretreating river and lake bottom mud and municipal sludge to obtain slurry with the water content of 70-80%, and respectively and accurately measuring the water content, the inorganic component content and the organic matter content of the slurry; uniformly mixing the two kinds of slurry to obtain total slurry, adjusting the concentration of the total slurry to be 10-15%, adding an agent into the total slurry according to the measured water content and the content of inorganic components and organic matters, and then carrying out filter pressing dehydration to obtain a mud cake with the water content of less than 40%; and carrying out carbonization ceramic preparation on the mud cake to obtain the ceramsite. According to the method, agents needed for conditioning, tempering and dehydration curing are combined into one, the mixing frequency of the raw materials is reduced, and the agents are added in the state that the raw materials are slurry, so that the agents and the raw materials are mixed more uniformly, and the reaction is more sufficient.
本发明涉及市政环境工程技术领域，尤其涉及一种利用河湖底泥和市政污泥协同烧制陶粒的方法。本发明提供的烧制陶粒的方法步骤包括：分别对河湖底泥和市政污泥进行预处理得含水率为70％～80％的泥浆，并分别准确测定其含水率、以及无机成分和有机质的含量；将两种泥浆混合均匀得总泥浆，调整其浓度为10％～15％，根据测得的含水率、以及无机成分和有机质的含量，向总泥浆中添加药剂，之后进行压滤脱水，得含水率＜40％的泥饼；将泥饼经碳化制陶步骤得到陶粒。该方法将调理调质和脱水固化所需的药剂合二为一，减少了原料的拌合次数，且在原料为泥浆的状态下加入，使药剂与原料混合更为均匀、反应更加充分。
