Detailed Explanation of the Treatment Process for Difficulties in Photovoltaic Wastewater Treatment

With the rapid development of the solar photovoltaic industry, photovoltaic wastewater treatment has become an important issue. Due to the high concentration of salt, heavy metal ions, and organic compounds in photovoltaic wastewater, special attention needs to be paid to the treatment processes for these wastewater. This article will provide a detailed introduction to the difficult treatment processes in photovoltaic wastewater treatment.

1、 Difficult components in photovoltaic wastewater

The difficult components in photovoltaic wastewater mainly include heavy metal ions, high concentrations of salt, and organic matter. These components pose significant risks to the environment and human health, therefore effective treatment processes are needed to remove them.

2、 Processing technology

1. Removal of heavy metal ions

In photovoltaic wastewater, heavy metal ions such as copper, nickel, cadmium, etc. are one of the main pollutants. These heavy metal ions can cause significant harm to the environment and human health, therefore effective treatment processes are needed to remove them. The commonly used methods for removing heavy metal ions include chemical precipitation, adsorption, and ion exchange. Among them, chemical precipitation method is one of the methods, which involves adding an appropriate amount of precipitant to react heavy metal ions with the precipitant to form a precipitate, thereby achieving the goal of removal.

2. Removal of high concentration salt

The salt content in photovoltaic wastewater is relatively high, and these salts mainly come from the chemicals used in the production process of solar panels. High concentrations of salt not only cause environmental pollution, but also have an impact on the lifespan and stability of wastewater treatment equipment. Therefore, the removal of high concentration salt is an important challenge in photovoltaic wastewater treatment. The commonly used methods for removing high concentration salt include electrodialysis, reverse osmosis, and forward osmosis. In the process of electrodialysis, the use of an electric field causes ions in wastewater to migrate through membrane pores to the other side, thereby reducing the salt content in the wastewater. The reverse osmosis method and forward osmosis method use semi permeable membranes to allow water molecules in wastewater to pass through the membrane pores, while salt is intercepted, thereby reducing the salt content in wastewater.

3. Organic matter removal

Photovoltaic wastewater also contains a large amount of organic matter, which mainly comes from organic solvents and cleaning agents used in the production process of solar panels. The presence of organic matter not only pollutes the environment, but also affects the stability and efficiency of wastewater treatment equipment. Therefore, organic matter removal is another important challenge in photovoltaic wastewater treatment. The commonly used methods for organic matter removal currently include activated carbon adsorption, biodegradation, and photocatalytic oxidation.

Among them, activated carbon adsorption method is one of the methods, which removes organic matter in wastewater by passing it through a column of activated carbon. The principle of biodegradation is to use the degradation effect of microorganisms to decompose organic matter in wastewater into simple inorganic substances, thereby achieving the goal of removal. The catalytic oxidation method involves adding an appropriate amount of catalyst to wastewater, and then irradiating it with ultraviolet light to decompose the organic matter in the wastewater into inorganic substances such as water and carbon dioxide, thereby achieving the goal of removal.

3、 Conclusion

The treatment process of photovoltaic wastewater is an important issue in the current development of the solar photovoltaic industry. In order to better solve these difficult problems, it is necessary to research and develop more efficient, environmentally friendly, and economical treatment processes. At the same time, it is necessary to strengthen the control and management of photovoltaic wastewater discharge to reduce the harm to the environment and human health.
