Description

TECHNICAL FIELD

[0001] The utility model relates to underwater sediment silt treatment technical field, concretely relates to a adjustable underwater silt treatment equipment. BACKGROUND

[0002] Underwater sediment silt refers to the sediment that is deposited in still water or slow flowing water environment, and is formed by physical chemistry and biochemistry and is rich in organic matter and mineral matter. If the silt is deposited too much, it will cause serious influence to water quality and ecological environment, so it is necessary to regularly treat the underwater sediment silt. The current common treatment method of underwater sediment silt includes biological degradation method, physical treatment method, chemical treatment method and the like.

[0003] When the biological degradation method is used to treat the underwater sediment silt, biological agent (biological enzyme or biological bacteria) needs to be added to the water bottom to activate the aerobic bacteria in the sediment silt, so as to remove the soluble organic matter and part of the insoluble organic matter in the silt, and realize the silt reduction and water quality purification. In the process of biological degradation, aeration is carried out in the water body to increase the oxygen supply, which can promote the activity of microorganisms and the degradation effect.

[0004] In the prior art, the adding process of biological agent generally uses a dosing pipe to directly add to the water body, and an aeration device is arranged in the water body to carry out aeration. Such operation mode has the following shortcomings: since the adding point position of biological agent is generally fixed, the setting position of aeration pipe or other aeration equipment is also fixed, and the aeration is not easy to fully mix the biological agent with the silt at the water bottom, so that the biological degradation efficiency is not high, and the soluble organic matter in the water cannot be effectively removed; in order to fully biodegrade the underwater sediment silt, it is necessary to increase the adding amount of biological agent and increase the arrangement of aeration equipment, which will increase the silt treatment cost.
