Latest Patents

Lijuan Wu's notable patent is titled "Method for reducing release of resistance genes during sludge anaerobic treatment." This innovative method involves controlling the concentration of to-be-treated sludge in a concentration tank to between 12-20 g/L through sedimentation under gravity. The concentrated sludge undergoes a supersonic pre-treatment for 5-30 minutes using a power range of 0.1-0.5 kW and a frequency of 10-40 kHz. Subsequently, the pre-treated sludge is transferred to an anaerobic treatment device, where the anaerobic treatment occurs for 4-12 days at a temperature of 20-37°C. Wu's method allows for the detection of resistance genes in both the residual sludge and the supernatant liquid, and utilizes feedback dosage of an alkali liquid to maintain the pH between 9.0 and 11.0 during treatment.
