AI Technical Summary

Technical Problem

Existing wastewater treatment technologies struggle to effectively and efficiently decompose persistent and bio-resistant contaminants like estrogen, which pose ecological risks due to their persistence and toxicity, with advanced oxidation technologies having limitations and biological enhancement techniques often failing to meet degradation expectations.

Method used

The development of double-embedded particles composed of artificial photosynthetic particles (calcium alginate hydrogel with MOF material NH2-MIL-53(Fe) and white-rot fungi, and natural photosynthetic particles (calcium alginate hydrogel with green algae and Bacillus subtilis), which synergistically degrade estrogen through photocatalysis, enzymatic reactions, and microbial activity.

Benefits of technology

The double-embedded particles enhance the degradation efficiency and stability of microorganisms, allowing for effective removal of estrogen from wastewater under various environmental conditions, reducing ecological risks and achieving high decomposition rates of both conjugated and free estrogens.

Abstract

This invention provides double-buried particles for wastewater treatment and their application in the decomposition of estrogen in wastewater. [Solution] Double-embedded particles are obtained by preparing artificial photosynthetic particles embedded with photocatalysts and white-rot fungi, and natural photosynthetic particles embedded with bacteria and green algae. The double-embedded particles have a good removal effect on bound estrogen and artificially synthesized free estrogen in wastewater. The double-embedded photosynthetic particles solve the problems of low decomposition efficiency of biological treatment and poor toxicity reduction effect of advanced oxidation treatment in existing technologies, and provide a new means of wastewater treatment.
