In order to improve the treatment effect and energy consumption effect of mercury-containing wastewater, this paper designs an improved process technology that uses microorganisms combined with traditional mercury electrolysis technology to treat mercury-containing wastewater. It selected test reagents, raw materials, waste water and other materials, and used the principle of microbial luminescence to preferentially detect the product degree of waste water. Combined with the experimental results, a test scheme of mercury electrolysis method is established, and mercury electrolysis method is selected for further treatment. The treatment process is given. With the help of microbial detection technology, the best energy-saving treatment process conditions were determined. The optimal treatment conditions are mainly to set the pH value to 2.5~3.0 and the effective chlorine to 50~100 ppm. At the same time, from the perspective of the removal effect, mercury-containing electrolysis technology is used for advanced treatment of mercury-containing wastewater to achieve zero mercury concentration and achieve good results. The effect of the method meets the energy-saving design requirements of the method.
