Benefits of technology

This technology uses different ways for absorbing harmful materials from water containing them during processing or production processes such as mineral extraction operations. By combining this process into one system that can treat both acidic and basic waters simultaneously, these benefits include effective removal of harmgants without causing secondary pollution, efficient use of activated charcoal (AC) particles, improved clarity levels caused by AC being mixed together with an organosilicon compound called polysulfonamide), enhanced degradation rates due to UV light exposure, and increased efficacy when added along with certain types of chemical agents like chlorine gas.

Problems solved by technology

This patented describes how harmful materials like lead (Pb) may accumulate over time inside pipelines used for carrying out certain processes such as cleaning up contaminated soil on surfaces. These deposits could affect public safety due to their potential negative effects on humans and animals living around them. Additionally, these depositings have been found to contain valuable elements which cannot be recovered effectively without causing damage even when they were removed with traditional methods involving physical removal techniques.

Abstract

The invention discloses a method of treating manganese ore waste water. The method includes the steps of: adsorption, irradiation, secondary adsorption, and coagulation and emission. In the method, a secondary adsorption method is employed, wherein a large amount of harmful substances in the manganese ore waste water are adsorbed; the waste water is further disinfected by means of ultraviolet treatment. A self-made carbonized material employed in the invention has very strong adsorption and purification effects. The method is simple and has significant effects. Finally, a high-effective coagulator is employed and has compensation effects with the carbonized material, thereby improving efficiency.
