Thermal desorption technology is suitable for chemical, coking, pesticide, POPs and other industries, such as organic solvents, polycyclic aromatic hydrocarbons, benzene series, petroleum hydrocarbons, organochlorine pesticides, polychlorinated biphenyls and other pollutants. Chemical oxidation/reduction technology is suitable for the treatment of pollutants such as organic solvents, benzene series, petroleum hydrocarbons and organochlorine pesticides. The solidification/stabilization technology is suitable for the disposal of sites contaminated by heavy metals, radioactive substances, semi-volatile halogenated organic compounds, pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls and dioxins. Gas phase extraction technology is suitable for the remediation of VOCs contaminated sites such as benzene series, chlorinated solvents and volatile petroleum hydrocarbons. PRB reactive wall technology: This is a new technology for in-situ remediation of contaminated soil and groundwater. Using zero-valent iron as reaction medium can destroy volatile organic pollutants (VOCs) in groundwater, including common chlorinated solvents, such as tetrachloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCEs), chloroethylene (VC) and trichloroethane (TCA). Soil intensive mixing equipment: Soil intensive mixing uses proprietary mixing machinery and specially designed drill pipes and bits to mix and stir contaminated soil. Combined with different post-treatment technologies, different process combinations are formed, which is especially suitable for site remediation with complex stratum structure and poor soil permeability. In-situ geochemical stabilization technology (ISGS) is used to stabilize and repair non-aqueous fluid (NAPL), which is improved according to the method of treating pollutants by permanganate (KMnO4 or NaMnO4), and is mainly used to treat NAPL in aquifers. Biochemical agent treatment technology: the company can provide customers with the following agent technologies: ①DARAMEND series agents are used to treat soil and sediments containing chlorinated organics, organic explosives, petroleum hydrocarbons, ammonia, nitrates, heavy metals, organochlorine pesticides and other pollutants; (2) ②EHC series chemicals are used for in-situ treatment of groundwater and saturated soil with very good permeability, including chlorinated organics, organic explosives, petroleum hydrocarbons, ammonia, nitrates, heavy metals and organochlorine pesticides; ③ The improved groundwater circulation technology can effectively promote the treatment of inorganic pollutants, accelerate the biodegradation of persistent organic pollutants under aerobic conditions, or promote the biodegradation of organic explosives, perchlorates and chlorinated hydrocarbons under anaerobic conditions.
At the same time, the company also introduced geophone system and MIP system which are widely used in the world for sampling soil and groundwater, setting up groundwater monitoring wells and corresponding field detection.
