River bottom sludge treatment device and treatment method thereof

Abstract

The invention discloses a river bottom sludge treatment device and a treatment method thereof, and belongs to the field of sludge treatment devices. The river bottom sludge treatment device comprises a plurality of sedimentation pipes installed at the river bottom, the bottom ends of the sedimentation pipes are fixedly connected with plane plates, and guide plates matched with the plane plates are connected between every two adjacent sedimentation pipes; a culture cylinder is rotatably connected to the interior of the sedimentation pipe and comprises a rotating cylinder, a plurality of culture media are fixedly connected to the interior of the rotating cylinder, a liquid conveying pipe is inserted into the rotating cylinder and penetrates through the culture media, steering gears are rotatably connected to the two ends of the liquid conveying pipe, the steering gears are fixedly connected with the rotating cylinder, and a plurality of pairs of underwater gas detectors are fixedly connected to the flow guide plate. A servo motor is mounted in the flow guide plate, and a tooth column is fixedly connected to the power output end of the servo motor, so that the silt at the river bottom can be regularly cleaned, the cleaning process is controllable, and the ecological damage of the riverbed caused by excessive silt cleaning is prevented.

Description

technical field [0001] The invention relates to the field of sludge treatment devices, more specifically, to a river bottom sludge treatment device and a treatment method thereof. Background technique [0002] For the river channel used for farmland irrigation, it needs to be cleaned regularly, and the mixture mixed with sludge, aquatic plants and crop straw should be cleaned out from the river channel, which can not only ensure the smooth flow of river water in the river channel, but also not affect the irrigation of crops , It can also prevent aquatic plants and crop straws from rotting in the sludge and emit harmful gases to pollute the environment. Due to the flow of water, it may also cause other river water pollution and damage the ecological environment; [0003] At present, there are still the following problems in the silt cleaning of rivers used for farmland irrigation: a. The nutritional value of the sludge cleaned out by silt cleaning machinery is very suitable f...

AI Technical Summary

Problems solved by technology

[0003] At present, there are still the following problems in the silt cleaning of rivers used for farmland irrigation: a. The nutritional value of the sludge cleaned out by silt cleaning machinery is very suitable for crops, and then the silt is directly returned to the field for use, without using Cleaning up the aquatic plants in the silt will cause too many aquatic plants in the farmland, which will affect the growth of crops; b. The silt cleaning machine used can directly clean out the silt at the bottom of the river. When returning to the field, it is easy to cause blockage of the silt conveying pipeline, affect the efficiency of river silt cleaning, and may also cause damage to the silt cleaning machinery
