Powder preparation for inhibiting sulfate reducing bacteria activity by adopting tourmaline carried cobalt

Abstract

The invention discloses a powder for inhibiting the activity of sulfate-reducing bacteria in industrial wastewater by using tourmaline-carried cobalt, which relates to a bacteriostatic agent, and solves the problem of serious pollution of existing industrial wastewater, especially sulfate wastewater. The invention is made of 60-99.99% of tourmaline and 0.01-40% of cobalt chloride solid according to mass percentage. The preparation method is as follows: 1. Use nanometer or submicron tourmaline, put it into deionized water and stir; 2. Add nitrate solution, adjust the pH value to 4-8; 3. Add cobalt and dispersant, stir; 4. Reduce pressure Separation by suction filtration and cleaning with deionized water; 5. Dry the separated and cleaned powder; 6. Grind the dried powder, and grind the calcined powder again to obtain the inorganic antibacterial powder. The invention adopts nanometer or submicron tourmaline, adopts surface modification, ion exchange and solid-phase synthesis method, not only effectively increases the cobalt loading amount, but also improves the bactericidal effect of the bacteriostatic agent.

Description

technical field The invention relates to an antibacterial powder, especially an inorganic antibacterial powder loaded with cobalt in natural tourmaline. Background technique In recent years, with the accelerated development of the national economy, the pollution of industrial wastewater, especially sulfate wastewater, has become more and more serious. The groundwater in many cities in my country has been polluted by sulfate to varying degrees. Discharge of sulfate-containing acidic wastewater directly into the water body without treatment will cause acidification of the receiving water body, lower the pH value of the water body, and cause potential corrosion; this type of acidic wastewater will also damage the soil structure and reduce crop yields. The latent period of sulfate wastewater is long. Although it has the activity of natural reducing bacteria, it will not have obvious negative effects in a short period of time. Once large-scale pollution is formed due to long-term...
