Focuses on the country's major environmental governance needs and the frontiers of environmental chemistry science. Based on the model of "restoring while increasing production", the novel technology of farmland soil remediation was developed and industrialized. Based on the principle of atomic-level active site catalysis, the Normal Temperature Catalytic Oxidation (NTCO) technology for the catalytic degradation of VOCs at ambient temperature and atmospheric pressure was inventively developed, and corresponding engineering demonstrations were carried out. Hosted the development of a nutrient organic carbon skeleton soil conditioner, which can repair damaged agricultural soil at a low cost. Engineering demonstrations show that the soil conditioner effectively blocks heavy metal migration to the root system, degrades pesticide residues such as DDT in soil, and increases crop yield. The technology has been identified as having an internationally advanced level, and the promotion of related products has achieved good social and ecological benefits.
