- Abstract:
- Based on the problems of long unloading time, many operators, easy blockage of pipelines and large water consumption in a sewer sludge treatment station in Suzhou, the treatment station was transformed technically to change the fixed grid spacing of the original discharge port from 100 mm to 200 mm, to add a double shaft crusher, to cancel the feeding grab, and to add a new hydrocyclone and sand water separator. The treated sewage is recycled to the front-end supply washing drum, sand washing unit and fine grid. The reconstructed sewer sludge treatment station has convenient unloading and high degree of automation, reducing three operators. The pipeline is no longer blocked by fine sand. The water consumption was reduced from 30 m3/t sludge before transformation to 5 m3/t sludge. The operation results show that the reformed process has the characteristics of stable operation, high degree of automation, no longer pipeline blockage and low water consumption, which can provide reference for the construction of similar projects.
