Device for electrolyzing waste water containing sulfuric acid with photovoltaic power source

Abstract

The invention provides a device for electrolyzing waste water containing sulfuric acid with a photovoltaic power source. According to the principle that water electrolyzes the hydrogen gas, pure water does not have electrical conductivity, on the contrary, dilute sulfuric acid or other substances need to be added into the pure water to increase the electrical conductivity of water, and the purpose that the water electrolyzes the hydrogen gas is achieved. The waste water generated by production of lead-contained waste disassembling and smelting industries and pole plate storage battery industries is rich in dilute sulfuric acid, heavy metal and other substances and is a good conducting solution, therefore through the existing technology that solar energy is converted into electric energy, the waste water generated in the production process electrolyzes the hydrogen gas, on one hand, the pollution treatment costs of enterprises are reduced, and economic benefits of the enterprises are increased; on the other hand, the environmental pollution can be completely avoided, and ecological environment balance is maintained; the key point is that the electrolyzed hydrogen gas is a renewable clean energy source, the calorific value of the electrolyzed hydrogen gas is high, the combustion product is H2O, the environment cannot be polluted, and fuel can be provided for high-energy-consumption enterprises, such as lead smelting enterprises.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a device for electrolyzing wastewater containing sulfuric acid by using a photovoltaic power source. Background technique [0002] Lead and its products are widely used in batteries, cable sheathing, machinery manufacturing, shipbuilding, light industry, radiation protection and other industries, and are an important metal. However, in the process of chemical products and recycling, sulfuric acid-containing wastewater is usually accompanied. Improper disposal of sulfuric acid-containing wastewater into the natural environment will not only acidify the water body or soil, cause harm to the ecological environment, but also waste a lot of resources. At present, the common methods for treating sulfuric acid wastewater include high-temperature concentration method, oxidation method, and neutralization treatment method. [0003] The high-temperature concentration method ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: the strong corrosion of sulfuric acid and the acid mist are very harmful to equipment and operators, the actual operation is very troublesome, and heating wastewater containing sulfuric acid to concentrate it requires a lot of energy consumption, and the production cost is high.

At present, the above-mentioned control measures are not only costly, but also have secondary hazards.
