AEROBIC BIOLOGICAL TREATMENT METHOD

摘要

PURPOSE:To perform efficient biological treatment, by supplying an oxygen- containing gas and a particulate-containing liquid to a jet stream generator and discharging an air bubble-containing stream containing a particulate from the discharge port of a flow distributor to apply biological treatment thereto. CONSTITUTION:A gas-liquid mixing apparatus consists of a jet stream generator 1 and a flow distributor 2. A particulate-containing liquid is injected in the jet stream generator 1 from a liquid inlet 3 through an internal nozzle 5. The particulate-containing liquid injected from the internal nozzle 5 is mixed with the gas supplied from a gas inlet 4 in the jet stream generator 1 to form a liquid containing fine air bubbles and the particulate. This air bubble and particulate-containing stream is injected to the outside of the jet stream generator 1 from an external nozzle 6. By this method, biological treatment efficiency can be enhanced.
