Embodiment 1

[0098] For the water silt in the river, such as Figure 1-2 As shown, according to the first sensor in the sludge suction conveying device to detect the solid concentration of the sucked sludge, and the second sensor to detect the sludge cleaning depth, the sludge suction unit (ie, the suction pump) is controlled by the intelligent control unit to suck the bottom sludge. Set the solid concentration of the sludge to 5%. When the actual signal value of the sludge solid concentration sent by the first sensor is higher than the set value of 5%, adjust and slow down the suction speed of the sludge suction unit. When the sludge solid concentration sent by the first sensor If the actual signal value of the concentration is 5% lower than the set value, adjust and speed up the mud suction speed of the mud suction unit. In order to ensure that the solid concentration of the sucked sludge is within a reasonable range, the stirred sludge will not spread to the surrounding water body due t...

Embodiment 2

[0102] For the water silt in the river, such as Figure 1-2 As shown, according to the first sensor in the sludge suction conveying device to detect the solid concentration of the sucked sludge, and the second sensor to detect the sludge cleaning depth, the sludge suction unit (ie, the suction pump) is controlled by the intelligent control unit to suck the bottom sludge. Set the solid concentration of the control sludge to 10%. When the actual signal value of the sludge solid concentration sent by the first sensor is 10% higher than the set value, adjust and slow down the suction speed of the sludge suction unit. When the sludge sent by the first sensor The actual signal value of the solid concentration is 10% lower than the set value, adjust and speed up the mud suction speed of the mud suction unit. In order to ensure that the solid concentration of the sucked sludge is within a reasonable range, the stirred sludge will not spread to the surrounding water body due to insuffi...

Embodiment 3

[0106] For the water silt in the river, such as Figure 1-2 As shown, according to the first sensor in the sludge suction conveying device to detect the solid concentration of the sucked sludge, and the second sensor to detect the sludge cleaning depth, the sludge suction unit (ie, the suction pump) is controlled by the intelligent control unit to suck the bottom sludge. Set the solid concentration of the sludge to 7.5%. When the actual signal value of the sludge solid concentration sent by the first sensor is higher than the set value of 7.5%, adjust and slow down the suction speed of the sludge suction unit. When the sludge solid concentration sent by the first sensor If the actual signal value of the concentration is lower than the set value by 7.5%, adjust and speed up the mud suction speed of the mud suction unit. In order to ensure that the solid concentration of the sucked sludge is within a reasonable range, the stirred sludge will not spread to the surrounding water b...

Abstract

The invention provides a water body silt cleaning and harmless treatment and deposal system, which comprises a silt suction and conveying device, a harmless treatment device and a dewatering treatment device in sequential connection through a silt conveying pipeline, wherein the silt suction and conveying device comprises the following parts including a silt suction unit, a first sensor, a second sensor and an intelligent control unit; the harmless treatment device is a rotating impeller driven by a driving motor; the dewatering treatment device is a filtering bag. The invention further provides a water body silt cleaning and harmless treatment and deposal method. The water body silt cleaning and harmless treatment and deposal system provided by the invention is combined with the process; the pollution on the peripheral water body in the suction process can be reduced; the dispersion degree of the silt is improved; good mixing of silt and added chemicals is realized; the treated mud cake has high dryness, can be used for reinforcing embankment and can also be conveyed out to be used for as filling soil or greening soil.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a water body sludge cleaning and harmless treatment and disposal system, in particular to a system for cleaning, harmless treatment and disposal of water body mud such as rivers and lakes. Background technique [0002] Environmental water bodies such as rivers and lakes are affected by soil erosion and will gradually form silt at the bottom of the water, and a large amount of pollutants will be transferred to the bottom mud as the water quality deteriorates. On the one hand, the increase of sediment affects the flood discharge function of the river, and on the other hand, the accumulated pollutants cause the phenomenon of black and odor in the water body, so the sediment of the environmental water body needs to be cleaned regularly. [0003] Commonly used dredging methods for water body sediment include drainage and excavation, that is, the sludge is dug out manual...
