Study on Temperature Control Strategy for Electrolytic Copper and Its Impacts on Ecosystem and Human Health

Copper is a very common substance that occurs naturally in the environment and spreads through the environment through natural phenomena. Humans widely use copper. For instance it is applied in the industries and in agriculture. The production of copper has lifted over the last decades. Due to this, copper quantities in the environment have increased. This metal, the tea-coloured organic material found in soil and rivers and coastal waters, is not ecologically toxic to humans but it is somewhat toxic to fish and very toxic to phytoplankton” -- a fundamental link in the food chain. Natural humic substances and other copper-binding compounds may also greatly affect the toxicity and bioavailability of metals in rivers and coastal waters. When organic matter binds with metals, noted Professor Voelker, the metals often become less toxic. However, in environments such as groundwater, they may also become more mobile. Among widely used heavy metals, Cu(II) ions have received special attention due to its eco-toxic effect (i.e., negative impacts on ecology and environment), bioaccumulation in food chain and its persistent in nature. Additionally, copper is most valuable substance, which is mostly washed away in wastewater and dissipate to environment resulting in economic loss. Cu(II) ions have major contribution, cause several adverse effects even at very low concentration such as an extreme mucosal bothering, hypertension, hepatic and renal harm, far reaching slender harm, gastrointestinal irritation, vomiting, irritation of the focal sensory system took after by dejection, and conceivable necrotic changes in the liver and kidneys. But human beings needs copper in the life circle, so for improving on the quality of copper cathode and saving energy, the analysis of the whole process of electrolytic copper production is needed. It indicates that the copper ion and acid ion concentration are the most important factors affecting the quality of copper cathode, however, the copper ion and acid ion concentration as major variables of objective function determined by accurate electrolyte temperature control. Therefore, in this paper, an improved differential evolution algorithm is proposed to optimize the multi-objective function, and the optimal solution set of the multi-objective problem is determined. Then, a new improved ideal point method is proposed based on the ideal point method. Finally, the optimal temperature and copper ion concentration are determined to optimize the electrolysis process. The optimal value of temperature is taken as the given value of the control system. The fuzzy adaptive PID algorithm is used for simulation analysis and experimental verification. The results show the correctness and feasibility of the algorithm under the background of low carbon energy saving appeal.
