[0002] Pesticides are special chemicals used to prevent, eliminate, or control diseases, insects, weeds, and other harmful organisms that threaten agriculture and forestry, as well as to purposefully regulate the growth of plants and insects. They play a vital role in agricultural production, improving crop yield and quality and protecting crops from pests and diseases. Pesticide wastewater treatment is a crucial aspect of environmental protection because the wastewater generated during pesticide production contains various toxic and harmful substances. If these substances are discharged directly into the environment without treatment, they will cause serious pollution to water bodies and soil. Pesticide wastewater is characterized by its complex composition, high toxicity, and numerous recalcitrant substances, thus requiring complex treatment technologies.
