Title:
NON-SLUDGE HIGH-SPEED WASTE WATER TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2004/080903
Kind Code:
A1
Abstract:
It is intended to provide a non-sludge high-speed wastewater treatment system equipped with a means of culturing a strong oxidative digestion bacterium, a means of supplying oxygen at a high concentration and a means of solid/liquid separation. The above-described means of supplying oxygen at a high concentration may have a means of supplying oxygen and a means of generating fine bubbles. By the above-described means of generating fine bubbles, bubbles having a diameter not more than about 3 μm may be generated. The above-described means of solid/liquid separation may comprise a porous membrane. In a preferred case, the above-described strong oxidative digestion bacterium may comprise a bacillus which shows a growth speed expressed in generation time in a complete medium at 30°C or 30 minutes or below and belongs to the genus Bacillus. Alternatively, above-described strong oxidative digestion bacterium may be a PVA-digesting bacterium belonging to the genus Pseudomonas or Acinetobacter. It is also intended to provide a non-sludge high-speed wastewater treatment system which is further equipped with a means of removing oil, a means of removing nitrogen, a means of removing heavy metals and a means of sterilization and deodorization.
