Abstract: A method of promoting the treatment of coking wastewater using photocatalytic electrode coupled with microbial fuel cellin the technical field of coking wastewater treatment, energy-saving and resource utilization. La-ZnIn2S4/RGO/BiVO4 and silica sol were fixed and coated on stainless steel mesh to form conductive catalytic composite membrane electrode. HSO3−was added to coking wastewater. Graphite Carbon rods are inserted into the anodic chamber with microorganisms and connected the cathode with wires to form circuit loops. Halogen tungsten lamp was applied as light source to act on the catalytic electrode, forming a coupled system with photocatalytic electrode and microbial fuel cell for treating coking wastewater. The effects of La-ZnIn2S4/RGO/BiVO4 catalysts with different RGO contents on the catalytic degradation of coking wastewater were realized, and the effects of NaHSO3 and Na2SO4 solutions at the same concentration on the degradation of coking wastewater were also realized.

Abstract: The present invention belongs to the technical fields of civil engineering, smart material and health monitoring, and provides a viscous damper fluid viscosity monitoring device and method based on piezoceramic transducers, comprising piezoceramic transducers, wires, corks, a baffle and a viscous damper. When the fluid viscosity of the viscous damper changes, the energy dissipation of pressure waves during propagation in a fluid will change, and signals received by the piezoceramic transducers will change, so that the viscosity of the fluid in the viscous damper can be calculated by the amplitude change of the signals received. The device of the present invention has a simple structure and accurate monitoring results, and provides a simple and feasible method for real-time monitoring of fluid viscosity of viscous dampers in engineering.
