Problems solved by technology

There are silty ports in foreign countries that have used inorganic chemoautotrophic bacteria to delay the compaction speed of floating mud, thereby increasing the application time of navigable water depth, which has produced huge economic benefits. However, the growth of inorganic chemoautotrophic bacteria depends on other Self-growth, which grows extremely slowly and produces low yields, resulting in it taking up to several years to produce results

Abstract

The invention discloses a method for alleviating density of float sludge of a silt port by using heterotrophic bacteria microorganisms. The method comprises the following steps: I) screening heterotrophic bacteria which can generate extracellular polymeric substances and alleviate float sludge of the silt port from float sludge of the silt port; and II) generating the extracellular polymeric substances by heterotrophic bacteria and carrying out interaction on extracellular polymeric substances and the float sludge of the silt port so as to alleviate the dense speed of the float sludge of the silt port. By selecting the heterotrophic bacteria microorganisms of the float sludge of the silt port, interaction on extracellular polymeric substances (EPS) and the float sludge of the silt port is carried out to alleviate the dense speed of the float sludge of the silt port, so that the application period of navigational depth is prolonged, the maintaining and dredging period can be prolonged, the operational cost of port enterprises is lowered, and the economical benefit is improved.

Description

technical field [0001] The invention relates to a method for slowing down the compaction of floating mud in a muddy port, in particular to a method for slowing down the compaction of floating mud in a muddy port by using heterotrophic microorganisms. Background technique [0002] For silty ports, the deposition of sediment will have a great impact on the navigation of ships in the port, and regular cleaning of port deposition not only wastes a lot of manpower, material resources, and funds, but also affects the environment. The floating mud has a certain fluidity, and the floating mud with a weight less than the seaworthy weight can be used as the water depth without affecting the ship's operational performance, thereby prolonging the maintenance and dredging cycle and saving a lot of maintenance and dredging costs for port enterprises. However, the floating mud will continue to become dense with the passage of time, causing the weight value of the floating mud to gradually ...
