Soil is the foundation of the survival of the people. Based on the parent material and under the long-term interaction of physics, chemistry and biology, it is a soil-like substance that evolves continuously. It consists of four parts, namely solid phase, liquid phase and gas phase, as well as living organisms. However, at present, the soil has been continuously destroyed by human beings, such as the pollution of heavy metals and organic compounds, resulting in a large area of soil in a state of "unemployment", and even threatening the life security of human beings.

At present, soil remediation technology is divided into three parts -- phytoremediation, microbial remediation and chemical remediation. Phytoremediation of soil takes a long time, generally lasting for several decades, and mainly depends on the adsorption and fixation of plant roots. Although microbial remediation costs less, it also takes a long time, and microorganisms are also subject to many limiting factors of soil, such as soil pH and base ions. So far, the chemical remediation of soil has been widely applied. For example, Fenton reagent, fenton-like reagent, persulfate reagent, potassium permanganate reagent, potassium persulfate reagent and so on a series of products. Such oxidants as Fenton reagent and Fenton-like reagent have a fast oxidation rate and are greatly affected by pH and concentration. Moreover, hydrogen peroxide is easy to decompose, leading to oxidation failure. Moreover, its strong oxidation property will have a strong impact on the physical and chemical properties of soil itself. Potassium permanganate reagent is easy to cause manganese toxicity in soil due to the manganese element contained in it, which causes heavy metal pollution in soil -- secondary pollution. Due to the stability of its structure, persulfate reagent needs excitation (such as Fe2+, temperature, radiation, etc.) for its oxidation performance, and the excitation process is easy to lead to the loss of its own oxidant, thus causing unnecessary economic loss.

Day everyone would fly Shanghai figure soil chemical industry co., LTD is committed to repair as the main business, tracking soil chemical remediation technology at home and abroad in recent years, and for the relationship between soil physical and chemical character, the physical and chemical properties and soil properties have certain research on the relationship between the antioxidant and, on this basis to develop an advanced oxidation soil repair agent, its chemical property is stable, easy to transport storage, wide range of characteristics of biodegradable pollutants, as oxidant effect duration is long, etc, comprehensive oxidation properties beyond the traditional soil of antioxidant, potassium permanganate to avoid the secondary pollution problem, Fenton oxidation problem and classes of Fenton reagent, and overcome the persulfate react slowly, need to activate, pre-reaction consumption big, the temperature requirements higher shortcomings, and overcome the problem of desorption of organic pollutants in soil, but also has strong permeability, pH applicability is wide and with the aid of trace elements in the soil in promoting oxidation effect, no pollution of groundwater, promotes the microbial remediation of soil, ao figure industrial co., LTD. According to different soil restoration can also provide more appropriate construction scheme.
