METHOD FOR CLEANING OFF ORGANIC DEPOSIT RESULTING FROM SPILLED CRUDE OIL OR WASTE WATER ON WATER BOTTOM

摘要

PURPOSE:To rapidly and effectively decompose an org. deposit and to prevent water or environmental pollution by using an aerator and a biofence carrying photosynthetic bacteria to decompose and clean off the org. deposit resulting from spilled crude oil or waste water on the water bottom. CONSTITUTION:An air compressor 4, a photosynthetic bacteria tank 5 and a surfactant tank 6 are arranged on a truck ship 3 provided on the water surface 2, and an air feed pipe 7 from the compressor 4 and a liq. feed pipe 8 from the photosynthetic bacteria tank 5 and the surfactant tank 6 are connected to the lower surface of an aerator 9 set on the water bottom. An anchor 14 and a float 15 are furnished to a fibrous net 13 to constitute the vertical biofence 11, and many bioboxes 16 are fixed to the net. A horizontal biofence 12 is obliquely laid. The biobox 16 consists of a plastic vessel and a nonwoven fabric cover as the lid and freely detachably fixed with a hook, etc.
