IMPROVED BIOLOGICAL WASTE WATER PURIFICATION REACTOR AND METHOD |
摘要 |
A biological purification reactor and process, wherein the water to be treated and oxygenated gas are sent in ascending co-currents in the same reactor comprising as a biological filtering material a packed bed and a volume of movable, hollow carriers having a protected surface area for growth of the microbial film. The purifying reactor (1) comprises a space for expansion and removal of sludge (2), a gas injection system (4), a fluid injection system (3), a biological filter comprising a packed bed (5) of particles retained in a lower part of said reactor by a perforated retention ceiling (6) against upward movement, and a volume of movable particles (10) located within the said space for expansion and removal of sludge (2). The movable particles have a higher density than the packed bed particles. The purifying method further comprises periodical back washing steps. |
