River and lake sludge treatment and disposal system

Abstract

The invention relates to a river and lake sludge treatment and disposal system, and belongs to the technical field of environmental geotechnics. The treatment and disposal system is composed of a controlling source separating and modifying solidification system, an in-situ modifying solidification system, a forming and sintering system, a modified sludge transport device and a belt transport device. Reaming and sucking equipment and sludge grabbing equipment move in parallel for dredging, it is ensured that the sludge is cleared thoroughly, and dredging efficiency, effect and economy are ensured. The in-situ modifying solidification system and the controlling source separating and modifying solidification system are used at the same time, sludge processing efficiency can be ensured, and processing cost is solved. Impurities in the sludge can be removed through a screening impurity removal device and a vibrating impurity removal device, and follow-up treatment and disposal of the sludge are convenient. A dehydration agentia is added into the sludge through an automatic aqueous solution adding device, and fast setting of the sludge is ensured. A stabilizing and solidifying agentia is added into the sludge through an in-situ modification device and a powder adding device to stabilize and solidify pollutants in the sludge. System parameters are set on a computer, data is processed through a computer program, and system efficiency is greatly improved.

Description

technical field [0001] The invention relates to a river and lake sludge treatment and disposal system, which belongs to the technical field of environmental geotechnical engineering. Background technique [0002] With the rapid development of urbanization in China, a large number of black and smelly rivers and lakes urgently need to be treated. The root of black and smelly river and lake governance lies in silt control. River and lake silt has the characteristics of high hydrophilicity, high water content, high organic matter content, low permeability, large volume, and contains different levels of pollutants and garbage, which makes it difficult to deal with in the project and is prone to secondary pollution. Therefore, how to standardize system processing and disposal is the key problem currently facing. [0003] At present, the main treatment and disposal methods involve: 1) reamer suction and dehydration treatment on shore. At present, this method lacks a unified cons...

Problems solved by technology

Due to the limitation of the working principle, it is difficult to completely remove the river and lake silt, and it is difficult to remove the floating mud with high organic content; at the same time, this method lacks the removal of debris, and a large amount of debris (garbage, large-sized stones, etc.) ) lead to difficulties in su
