Comprehensive recovery and utilization method of various waste waters in iron and steel plant

Abstract

The invention discloses a method for comprehensively recycling various wastewaters of an ironworks, pertaining to the technical field of wastewater disposal. The process sequence is as follows: regional division is carried out according to the difference of positions of various working procedures of the ironworks and calculations of water quality and balance in water quantity are carried out by combining with drainage characteristics and water consumption characteristics of different working procedures; classification of treatment is carried out according to the result of the calculations. The method has the advantages of being capable of avoiding the defects and shortages of the traditional processing method and effectively improving the balance in water quantity and water quality of the ironworks, thereby realizing the 'zero' draining. The method is a novel technology for comprehensively recycling various wastewaters of the ironworks, particularly applicable to projects for comprehensively recycling various wastewaters of long-running large-scale integrated iron and steel works. The technology can not only be adopted to realize the 'zero' draining of various wastewaters of the ironworks, effectively protect water environment and save water resources, but also reduce the overall investment of the projects and the comprehensive running costs and realize comparatively good economic and social benefits.

AI Technical Summary

Benefits of technology

Introduction into this new technical solution described in the patented text describes an improved method called Diversion System (DDS) for producing cleaned or purified liquid products like oxygen gasoline, diesel fuel, fertilizers, chemicals, plasma, ionics, hydrocarbons, chlorides, sulfates, acids, bases, salts, organic compounds, heavy metals, pesticides, pharmaceuticals), gases, volatile substances, solvents, and others. These liquors have varying levels of contamination depending upon their origin and purpose usage. They may also contain harmful components such as lead, chromium, selenium, fluorochemistry, peroxynitrity, formaldehydes, methane, ethylene, tungsten, silicon dioxysulfonimne, urancesite, calcium carbonate, magnesiocyanrite, bacterial cells, yeasts, fungus spores, ferrous metal residue, pigment particles, clay minerals, suspended matter, sediments, rust grains, oxidized colloidal crystal structures, and mixtures thereof. By combining these materials during processing, it becomes more efficient than current methods alone.

Problems solved by technology

This patented problem addressed in this patents relates to improving the efficiency of utilization of waste waters during different stages or phases of producing metallic products (such as steel). Specifically, current methods involve disposal of excessive amounts of contaminated water that can harm both environmental health and human wellbeings when released into nature without being treated properly. Additionally, there may exist issues with ensuring proper management over these streams' volumes and concentrations.
