Composite ceramsite as well as preparation method and application thereof
The invention provides composite ceramsite as well as a preparation method and application thereof. The preparation method of the composite ceramsite comprises the following steps: doping CoFe-LDH powder into a ceramsite matrix containing fly ash, granulating, and calcining to obtain the composite ceramsite. The CoFe-LDH powder and the ceramsite matrix are jointly used as raw materials, on one hand, metal elements contained in the fly ash in the ceramsite matrix and the CoFe-LDH powder formed after the CoFe-LDH powder is calcined have a catalytic effect on DBDP, on the other hand, the ceramsite matrix is used as a carrier of the CoFe-LDH powder, the CoFe-LDH powder and the ceramsite matrix are calcined, the CoFe-LDH powder and the ceramsite matrix have a synergistic effect, a DBDP system can be efficiently activated, and the DBDP system can be effectively activated. The diuron removal rate of the DBDP system is further improved, meanwhile, the discharge time of the DBDP system can be shortened, the energy consumption can be reduced, and the energy utilization rate can be improved.
本发明提供了一种复合陶粒及其制备方法和应用，复合陶粒的制备方法如下：向含有粉煤灰的陶粒基质中掺杂CoFe‑LDH粉末后进行造粒，煅烧得到复合陶粒。本发明以CoFe‑LDH粉末和陶粒基质共同作为原料，一方面，陶粒基质中的粉煤灰含有的金属元素以及CoFe‑LDH粉末煅烧后形成的CoFe‑LDO粉末分别对DBDP有催化作用，另一方面，陶粒基质作为CoFe‑LDH粉末的载体，经过煅烧，两者协同作用能够高效活化DBDP体系，进一步提高DBDP体系对敌草隆的去除速率，同时，可以缩短DBDP体系的放电时间，降低能耗，提升能量利用率。
