Hydrogen peroxide works as what type of agent in wastewater treatment?

Hydrogen peroxide is known for its strong oxidizing properties, making it an effective agent in wastewater treatment. As an oxidizing agent, it can facilitate the breakdown of various organic pollutants by providing oxygen. This process helps to enhance the removal of contaminants from the water, making it a crucial component in certain treatment processes, such as advanced oxidation processes and disinfection.

In wastewater treatment, the introduction of hydrogen peroxide leads to the formation of hydroxyl radicals, which are highly reactive and can degrade organic compounds that are otherwise resistant to biodegradation. This process not only reduces the concentration of harmful substances but also aids in the overall treatment efficiency of the system.

The other roles mentioned in the options, such as coagulant and flocculant, refer to substances that help in aggregating and settling suspended particles in wastewater. These functions are distinct from the actions of hydrogen peroxide, which primarily focuses on oxidation rather than solid removal or particle agglomeration. Understanding the specific function of hydrogen peroxide as an oxidizing agent is essential for effectively applying it in wastewater treatment practices.
