Applying TRIZ Theory to Improve the Quality Stability of Resin Regenerate Wastewater in Molybdenum Wastewater Treatment System

Abstract

For the molybdenum wastewater treatment system using the ion exchange resin method in order to effectively reuse the molybdenum metal resources the resin regeneration waste liquid needs to meet the recycling standards of the recycler Since there is no on-line analysis of the molybdenum metal ion concentration instrument in water the "concentration-time" curve should be prepared by sampling method at the initial stage of system construction as the basis for setting the regeneration liquid recovery interval During the actual operation there are still many factors that will cause the concentration-time curve to fail resulting in insufficient stability of the molybdenum metal concentration of the recycled waste liquid which cannot meet the recycling standards of the recycler This study uses the Cause and Effect Analysis method to find out the possible causes and then improves the items according to the actual situation or the risk may occur However in order to improve the concentration and quality of the regenerated waste liquid molybdenum metal it may cause delay in system regeneration time and automatic control of the interrupt system Therefore the TRIZ contradiction matrix and TRIZ theory are used to find innovative methods that can take into account various engineering parameters
