Mobile river and lake water body and bottom mud treatment equipment

Abstract

The invention discloses movable river and lake water body and bottom mud treatment equipment. An ultraviolet lamp tube is ingeniously installed in a water pumping output pipe to achieve photocatalysis of chemical agents, the use amount of the chemical agents and the influence on the ecological environment of the water body are reduced, meanwhile, the installation space is not additionally increased due to the arrangement of the ultraviolet lamp tube, and the problem of installation space limitation of movable river and lake water and bottom mud treatment equipment is solved; the water body mixed with the chemical agents is discharged into rivers and lakes through a stirring pipe, a movable ship body is driven to move on the rivers and lakes, the water body mixed with the chemical agents is discharged into different point locations of the rivers and lakes, and meanwhile the chemical agents, the river and lake water body and bottom mud are fully stirred and mixed; and by adjusting the depth of the stirring pipe extending into the river and lake water body, the water body mixed with the chemical agent is discharged into water bodies and bottom mud of different depths of rivers and lakes, so that the chemical agent is fully mixed and make contact with the river and lake water body and the bottom mud, the dosing is more flexible, and the dosing uniformity is ensured.

Description

technical field [0001] The invention relates to the technical field of water body ecological restoration, in particular to a mobile river and lake water body and bottom mud treatment equipment. Background technique [0002] Water is the source of life and the most important natural resource for human development. However, with the rapid development of China's economy, in recent years, in some places, a large amount of domestic sewage, agricultural sewage, and industrial wastewater containing pollutants have been discharged into rivers and lakes, and most of the pollutants are finally deposited in the sediment at the bottom of rivers and lakes. At the same time, the pollutants deposited and adsorbed in the sediment of rivers and lakes will have a lasting impact on the overlying water body. When conditions such as temperature, pH, hydraulic power, and concentration of water pollutants change, the pollutants accumulated and adsorbed in the sediment will also change. Released i...

Problems solved by technology

This treatment method needs to reinstall the treatment pool every time for different rivers and lakes. It needs to pump up the water body and sludge, and then pump it back after treatment. It is time-consuming and laborious, and the treatment cost is relatively high.

(2) Fixed-point spraying type: artificially push the container containing the chemical agent to spray the chemical agent at the fixed point along the river and lake, but this method of adding the chemical agent is all through spraying and stirring on the water surface, and the effect is not ideal: if the chemical agent is injected, The chemical agent on the surface of the water body needs to react with the reducing substances in the water body before it can contact the sediment with the highest concentration of pollutants in the lower layer of the water body, which greatly reduces the effect of the agent; Most of the microbial agents will flow away with the water flow and fail to be released into the "bottom mud" where the microorganisms inhabit the lower layer of the water body

(3) Mobile treatment equipment: Since it needs to be moved on rivers and lakes, the volume and weight of the equipment should not be too large. In addition to the containers and delivery components for the chemical agents (and / or other treatment agents), the mobile treatment equipment must Generally, other corresponding auxiliary components (such as photocatalytic components, stirring components, etc.) will not be added to improve the use effect of chemical agents (because it will increase the volume and weight). Effect The relatively large amount of chemical agents used has a great impact on the ecological environment of the water body
