Kinetic degradation of amoxicillin by using the electro-Fenton process in the presence of a graphite rods from used batteries

This study reports the removal of amoxicillin(AMX) in aqueous media using the electro-Fenton process in the presence of a graphite cathode recovered from used batteries.The impact of the relevant parameters on the electro-Fenton process,namely the applied current intensity,the temperature,the initial concentration of AMX and the initial concentration of ferrous ions were investigated.The results showed that the optimal values were:I=600 mA,T=25℃,[AMX]_0=0.082 mmol·L~(-1) and [Fe~(2+])=1 mmol·L~(-1),leading to 95% degradation and 74% mineralization.The model parameters of AMX mineralization were determined using nonlinear methods,showing that it follows a pseudo-second-order kinetic.The Energy consumption(EC) calculated under the optimal values was found to be 0.79 kW·h·g~(-1) which was of the same order of magnitude of those reported in other findings;while it is noteworthy that the electrodes used in our study are of a lower cost.     

生料稳料CAM智能控制系统的研发与应用

对于入窑生料的控制，“稳料仓+生料下料阀+冲板式流量计”相结合的方案是目前水泥厂的主流配置，稳料仓和喂料量都采用PID进行调节，但这种配置方案，入窑生料喂料量不稳定的情况比较突出。本文以神经网络模型为基础，通过CAM（Cement's Automation and Management System，即水泥自动化与管理）智能控制系统平台，开发出生料稳料控制模块，并实际应用在水泥企业中，实时控制生料喂料量。经过长期现场实践，生料稳料控制器控制效果良好，能够有效地稳定生料喂料量，对回转窑生产有重要的推广意义。
