A device for monitoring and treating bottom mud at a river channel construction section and its construction method

Abstract

The invention discloses a monitoring treatment device for riverway construction fracture surface bottom mud and a construction method of the monitoring treatment device. The monitoring treatment device comprises bottom mud monitoring boxes, a bottom mud treatment pond and a bottom mud recycling pond; the bottom mud treatment pond is connected with the bottom mud recycling pond through a sludge output pipe which is provided with a mud pumping pump; a water inlet pipe is arranged on the top face of the bottom mud treatment pond and is communicated into water of a riverway; a stirring mechanism is arranged in the bottom mud treatment pond; the bottom mud monitoring boxes are connected with the bottom mud treatment pond through conveying pipes; and every two adjacent bottom mud monitoring boxes are connected through the corresponding conveying pipe. The construction method of the monitoring treatment device includes staking out in survey, foundation pit excavation, bottom mud treatment pond construction, bottom mud recycling pond construction, bottom mud monitoring box arrangement and bottom mud monitoring pilot running. The monitoring treatment device is simple in structure and remarkable in effect of riverway construction fracture surface bottom mud monitoring and clearing, the riverway construction fracture surface strength is improved, the bottom mud high in pollutant content can be conveniently treated, and secondary pollution formed by release of pollutants in bottom mud is prevented.

Description

technical field [0001] The invention relates to a device for monitoring and treating bottom mud at a river channel construction section and a construction method thereof. Background technique [0002] With the development of social economy and the improvement of living standards, people's requirements for environmental quality are getting higher and higher. Rivers and lakes play an important role in people's lives. In the early days, due to the lack of people's understanding of environmental pollution problems and the insufficient construction of sewage pipe networks and treatment facilities, rivers were to a large extent the main receptors for sewage discharge, and a large amount of untreated domestic sewage and industrial wastewater were directly discharged. Into the river, causing water pollution, and then the pollutants enter the bottom mud to form different degrees of polluted silt. Pollutants are exchanged between the sediment and the water body. When the amount of p...

Problems solved by technology

[0003] The water quality treatment in the prior art is generally aimed at purifying the water body, and does not treat the silt at the bottom of the river bed, and the silt at the bottom can not only absorb pollutants, but also release the absorbed pollutants into the water body to form secondary pollution. Therefore, while doing a good job of intercepting pollutants, it is still necessary to clean up the silt in order to better protect the quality of river water
