Description

A river and lake sludge treatment and disposal system

technical field

The utility model relates to a treatment and disposal system for river and lake silt, which belongs to the technical field of environmental geotechnical engineering.

Background technique

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.

At present, the main treatment and disposal methods involve: 1) reamer suction and dehydration treatment on shore. At present, this method lacks a unified consideration for the removal of sundries, the rapid concentration of mud by dosing, the stabilization and solidification of pollutants, and other links; at the same time, the solid content of the reaming sludge is low (about 3%-5%), and it is limited by the capacity of the dehydration equipment. Restrictions; this method has a long construction period and high cost for the treatment of a large amount of river and lake sludge. 2) Grab the mud ashore or suck it ashore, and carry out in-situ modification and solidification treatment after natural sedimentation. At present, either simply grasping mud to land or simply suctioning to land is adopted, and the two lack cooperation. Due to the limitations 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 matter content; at the same time, this method lacks the removal of debris, and a large amount of debris (garbage, large-sized stones, etc.) ) makes subsequent use difficult. Simple reaming suction ashore sedimentation, debris removal and dosing to accelerate sludge sedimentation are not fully considered, relying on natural sedimentation speed is slow, and the moisture content of sludge after sedimentation is high, subsequent modification and solidification treatment agents and construction costs are high.

Problem: For the silt that is difficult to grab directly by the mud grabbing equipment, the use of hinge suction equipment to remove it can ensure that the river and lake silt is completely removed; effect and economy. For sludge with good mud properties (it can settle quickly after adding dehydrating agent), it will directly enter the sludge sedimentation tank through the hinge suction equipment, and after natural settlement, it will be treated with the in-situ modified solidification system to reduce the processing capacity of the control source separation modified solidification system , improve the efficiency of sludge treatment; for sludge with poor mud properties (cannot settle quickly after adding dehydrating agent), hinge suction enters the control source separation modified solidification system for treatment, which can ensure the sludge treatment effect (through the control source separation modified solidification system The moisture content of the treated sludge cake can be <35%), which can effectively prevent the sludge with poor mud properties from entering the sludge sedimentation tank (the moisture content is high after natural precipitation, thereby increasing the cost of modification and curing); the in-situ modification and curing system is separated from the source control The modified solidification system is used at the same time, which can ensure the efficiency of sludge treatment and save treatment costs. The screening impurity removal device and the vibration impurity removal device can effectively remove garbage, stones and large-sized sandstones in the sludge, which is convenient for subsequent treatment and resource utilization of the sludge. At the same time, the sandstones screened out can be directly used as building materials. The automatic water agent adding device can add dehydrating agent to the sludge according to the designed addition amount to ensure the rapid sedimentation of the sludge and reduce the cost of subsequent modification and solidification of the sludge.
