Problems solved by technology

[0006] In the overall industry chain structure of water treatment chemicals in my country, the water treatment chemicals independently developed by the chemical industry are still in their infancy, and due to the particularity of industrial chromium salt wastewater, the corrosion and scale inhibitors commonly used at this stage are not suitable for water treatment Industrial chromium salt wastewater field
Due to the serious corrosion and scaling problems of the chromium salt wastewater evaporation system, the frequency of system maintenance has increased significantly, resulting in a significantly increased risk of production safety accidents

Abstract

The invention relates to the field of chromium salt wastewater treatment, in particular to an environment-friendly corrosion and scale inhibitor for a chromium salt wastewater evaporation system, which is prepared by adding 1mg of acrylic acid-2-acrylamide-2-methyl propanesulfonic acid copolymer (AA / AMPS), 3mg of polyepoxysuccinic acid (PESA) and 80mg of sodium gluconate (C6H11O7Na) into 0.5L of industrial chromium salt wastewater. The corrosion and scale inhibitor has the advantages of being good in corrosion and scale inhibition effect, environmentally friendly, economical and reliable.

Description

Technical field[0001]The present invention relates to the field of chromium salt wastewater treatment, and more particularly to an environmentally friendly chromium salt wastewater evaporation system corrosion inhibition scale inhibitor.Background technique[0002]High concentrations of salt wastewater are very common in all kinds of industrial wastewater in China. It refers to a type of wastewater, actual industrial production activities, electricity, steel, chemical and other industries in the actual industrial production activities. Alkali waste water, circulating sewage cooling water, reverse osmosis saline, ion exchange after regeneration waste liquid, etc. are all concentrated.[0003]High salt-containing wastewater has a high salt component concentration, a wide range of wastewater, partially heavy metal ions, etc., and therefore, when removing high concentration inorganic salts contained in wastewater, it is not suitable for use in microbial wastewater treatment. Industrial wast...
