Preparation method and application of ceramic filler for sewage treatment
The invention relates to a preparation method of a ceramic filler for sewage treatment, which comprises the following steps: S1, blending river sediment, domestic sludge, a foaming agent, an adhesive and water, baking, cooling, crushing and sieving to obtain a coarse material; s2, carrying out ball milling granulation on the coarse material to obtain a precursor; s3, the precursor is heated to 100-120 DEG C in a gradient mode, the temperature is kept constant, cooling is conducted, and the ceramic filler for sewage treatment is obtained, wherein the adhesive is prepared from the following components: modified chitosan, modified polyacrylate and hydroxylated kaolin; the modified chitosan is a product obtained by reacting chitosan with cysteine; the modified polyacrylate is a product obtained by reacting isobornyl acrylate, butyl acrylate, hydroxypropyl methacrylate and gallic acid. According to the invention, the porous ceramic filler structure with ideal morphology can be prepared, and the attachment, metabolism and regeneration of flora are facilitated, so that wastes in sewage can be efficiently and continuously treated.
本发明涉及一种污水处理用陶瓷填料的制备方法，其包括如下步骤：S1、将河道底泥、生活污泥、发泡剂、粘合剂和水共混烘烤，冷却后，粉碎并过筛，得到粗料；S2、将所述粗料球磨造粒，得到前驱体；S3、将所述前驱体梯度加热至100‑120℃，恒温，冷却，得到所述污水处理用陶瓷填料；其中，所述粘合剂采用的成分，包括改性壳聚糖、改性聚丙烯酸酯和羟基化高岭土；所述改性壳聚糖为壳聚糖与半胱氨酸反应所得产物；所述改性聚丙烯酸酯为丙烯酸异冰片酯、丙烯酸丁酯、甲基丙烯酸羟丙酯和没食子酸反应所得产物。本发明可以制备形貌较为理想的多孔陶瓷填料结构，有利于菌群的附着、代谢和再生，从而实现高效、持续处理污水中的废物。
