Preparation method of green and efficient heterogeneous Fenton catalyst
The invention discloses a preparation method of a green and efficient heterogeneous Fenton catalyst, and particularly relates to the technical field of environmental functional materials and sewage treatment.The preparation method comprises the steps of 1, red mud pretreatment, 2, waste glass pretreatment, 3, wet blank processing, 4, drying forming, 5, catalytic raw material preparation and 6, catalyst raw material baking. Two solid wastes of red mud and waste glass are taken as main raw materials, are bonded in a sodium silicate solution and then are sintered to form a catalyst matrix, the catalyst matrix is relatively high in structural strength, has more holes and is resistant to acid and alkali corrosion, and meanwhile, a transition metal ion solution is used for surface modification, so that the catalyst matrix can efficiently catalyze a heterogeneous Fenton reaction, and the catalytic performance of the catalyst matrix is improved. The method has the advantages that organic pollutants in water can be quickly removed, the catalytic efficiency and the metal dissolution rate can be controlled by changing the parameter conditions of the modified solution, pores of the catalyst can be uniformly formed by controlling the sintering temperature, and the metal dissolution rate can be effectively controlled by changing the roasting temperature.
本发明公开了一种绿色高效非均相芬顿催化剂的制备方法，具体涉及环境功能材料及污水处理技术领域，包括步骤一、赤泥预处理，步骤二、废旧玻璃预处理，步骤三、湿胚料加工，步骤四、烘干成型，步骤五、催化生料制取，步骤六、催化剂生料焙烤。本发明通过以赤泥和废玻璃两种固体废弃物为主要原料，在硅酸钠溶液黏合后，烧结而成的催化剂基体，其结构强度较高，孔洞较多，耐酸碱腐蚀，同时，使用过渡金属离子溶液进行表面改性，使其能够高效催化非均相芬顿反应，从而可以快速去除水中有机污染物，并通过改变改性溶液参数条件，可以控制催化效率和金属溶出率，可以通过控制烧结温度使催化剂成孔均匀，而改变焙烧温度可以使金属溶出率得到有效控制。
