AI Technical Summary
Existing sewage disinfectants such as liquid chlorine, sodium hypochlorite and ozone have problems such as safety risks, poor stability, high equipment costs and low utilization in sewage treatment, which are difficult to meet the increasingly stringent environmental protection requirements and sewage treatment needs.
A high-efficiency broad-spectrum sterilizer is prepared by combining modified titanium dioxide and modified activated carbon with dispersant. The stability and sterilization effect are improved through modification treatment, including impregnation and modification in hydrochloric acid and mixed salt solution, and then calcination treatment to form modified titanium dioxide and silver ion modified activated carbon supported by silver copper. After mixing, the sterilizer is prepared by ultrasonic dispersion.
It has achieved efficient killing of E. coli and Staphylococcus aureus, with a log value of up to 5 and has long-term antibacterial properties of up to 120 days, significantly improving the sterilization effect and antibacterial durability of sewage treatment.
