Abstract

The invention relates to the field of water environment treatment conducted by microorganisms, in particular to a method for repairing sediment pollution in an open sea area or a deep freshwater area, a river mouth and the like. The method comprises the steps: loading a bacterial strain with zeolite, coating with a flocculating agent and putting the coated bacterial agent into a to-be-treated water area so as to repair sediment petroleum and organic pollutants in the water area. The method mainly aims at the seawater / freshwater area with the water depth being 2 to 50 meters and has a good effect of repairing the sediment petroleum pollution and other organic pollution. The method is integral in system and simple in operating method, has the remarkable effect of repairing the sediment, no secondary pollution and high offshore construction safety, and is particularly suitable the special-function sea areas such as a petroleum exploitation area and an aquaculture area, and can guide implementation of sea sediment pollution repair engineering.

Description

technical field

[0001] The invention relates to the field of water environment treatment by using microorganisms, in particular, the invention relates to a repair method for sediment pollution in open sea areas or deep fresh water areas, estuaries and the like. Background technique

[0002] Marine organic pollution, especially marine oil spills and oil pollution has always been an important issue affecting the marine environment and marine ecology. At present, the emergency treatment of marine oil pollution, especially sudden oil spills, is mainly aimed at the initial stage of oil spills. The surface seawater of the ocean is treated with physical interception, recycling, and chemical dispersants for emergency treatment. However, there are no good physical and chemical treatment methods for seabed oil spills or oil pollution that sinks into seabed sediments with water movement. Environmental self-purification of oil-degrading microorganisms in sediments and artificial introdu...
