Magnetic coagulation technology
Magnetic coagulation technology is an efficient water treatment technology that enhances the flocculation and sedimentation effect by adding magnetic powder media. Its core principle is to add magnetic particles (usually micron-sized magnetic powder) to the traditional flocculation and sedimentation process. By utilizing the high-density characteristics of magnetic powder (the specific gravity of the formed magnetic flocs can reach 2.8 g/cm³) and surface adsorption characteristics, through mechanisms such as "adsorption bridging" and "charge neutralization", pollutants in water such as algae, fine suspended solids, colloids, and bacteria can effectively combine with the magnetic powder to form high-density flocs 8. These magnetic flocs can achieve rapid sedimentation and separation under the action of a magnetic field, and the sedimentation time is 40% shorter than that of traditional processes.
High-efficiency sedimentation technology
High-efficiency sedimentation technology is a combination of technologies that significantly improves the sedimentation efficiency on the basis of traditional sedimentation technology by optimizing hydraulic conditions, adding sludge reflux, and improving the dosing of flocculants.
Denitrification deep bed filter
The denitrifying deep bed filter is an advanced treatment technology that integrates physical filtration and biological denitrification functions.
Integrated water treatment technology
The integrated sewage treatment equipment is a high-efficiency sewage treatment equipment developed by our company based on years of sewage treatment experience and combined with advanced technologies at home and abroad. It is suitable for water pollution control in areas such as rural decentralized domestic sewage, urban sewage/emergency treatment of black and odorous water bodies, domestic sewage in remote factories and mines, highway service areas, and tourist attractions.
Sludge treatment technology
This technology is a combined process for sludge reduction, stabilization, and resource utilization that combines "deep dewatering" pre - treatment and "heat pump low - temperature drying" core treatment. Its goal is to gradually process raw sludge with a water content as high as 97% - 99% to a water content of less than 40%, significantly reducing the sludge volume and creating conditions for subsequent disposal or resource utilization.
Combined integrated deodorization technology
The double - dielectric barrier discharge low - temperature plasma module is used. Under the action of an external electric field, a large number of high - energy electrons (e) generated by the discharge bombard pollutant molecules, causing them to ionize and excite. Then, they combine with other active particles such as oxygen atoms (O) and hydroxyl radicals (OH), triggering a series of complex physical and chemical reactions. This transforms complex macromolecular pollutants into simple small - molecule safe substances or converts toxic and harmful substances into non - toxic, harmless, or low - toxic and low - harmful substances, thereby degrading and removing pollutants.
