AI Technical Summary

Technical Problem

The existing fixed reactors of the bacterial-algae symbiotic system have problems such as poor stability, low bacterial attachment efficiency, non-degradable materials, inability to move flexibly and adapt to complex waters, which limit their application in wastewater treatment.

Method used

A microrobot with a helical carrier and a protective shell was designed. It uses a biodegradable hydrogel material. The helical carrier provides a large surface area for bacterial attachment, the protective shell ensures stability, and a bacterial-algae symbiotic system is fixed by a bio-coating. It is fabricated using ultraviolet light curing printing technology.

Benefits of technology

It improves wastewater purification efficiency, enhances the stability and adaptability of robots, reduces secondary environmental pollution, and can be flexibly deployed to different water bodies for efficient purification.

Abstract

The application discloses a kind of micro sewage purification robot based on bacteria-algae symbiotic system and preparation method thereof.The robot includes: for carrying bacteria-algae symbiotic system spiral carrier, swimming ring-shaped protective shell, biological coating on the surface of spiral carrier, characterized in that, spiral carrier cross section is star-shaped distribution structure, and the axis is hollow;Microalgae are implanted in spiral carrier;Spiral carrier surface has fibronectin coating for bacteria attachment;With swimming ring-shaped protective shell.The application increases the attachment area and attachment firmness of bacteria on the carrier by spiral carrier design and fibronectin coating, not only improves the efficiency of bacteria-algae symbiotic system to decompose pollutants, but also makes the carrier have smaller resistance when moving in water;Protective shell structure avoids physical damage to the carrier, increases the service life of the robot, at the same time, spiral carrier and protective shell are made of degradable hydrogel material by light curing printing, which is environmentally friendly.
