Latest Patents

Renjie Chen holds a patent for a groundbreaking method titled "Method for sludge dewatering using kitchen waste to synergistically enhance anaerobic biological acidification and low-temperature thermal hydrolysis of excess sludge." This innovative method includes several key steps: first, it involves uniformly mixing excess sludge from a sewage treatment plant with kitchen waste at a controlled temperature of 36.5-37.5° C for 2-4 days. This mixture undergoes an anaerobic biological acidification reaction, which is then concentrated using centrifugation at a speed of 3000-5000 rpm for 5-10 minutes. The remaining residue is treated with low-temperature thermal hydrolysis at 100-140° C for 15-30 minutes. Finally, after the thermal treatment, the process yields a dewatered sludge cake and dewatered filtrate, achieving high-efficiency results without the need for chemical reagents.
