Embodiment 1

[0029] see figure 1 The first embodiment of the present invention provides a mechanical dehydration multifunctional mud conditioning pond for processing polluted bottom sludge in rivers and lakes, including a conditioning pond body 1, and the conditioning pond body 1 is provided with a slurry inlet 11, a slurry outlet 12, and a water outlet 13. The tank body 1 is provided with an air intake pipe 2 near the slurry outlet 12, and the air intake pipe 2 is provided with a plurality of ventilation holes 21, and the plurality of ventilation holes 21 are arranged on the air intake pipe 2 in different directions.

[0030] The first embodiment of the present invention provides a mechanical dehydration multi-functional mud conditioning pool for processing polluted sediment in rivers and lakes. By setting an air intake pipe 2 in the conditioning pool body 1 and ventilating the air into the air intake pipe 2, the gas is discharged in the conditioning pool body 1. The mud is disturbed, so ...

Embodiment 2

[0037] Another embodiment provided by the present invention differs from Embodiment 1 only in that: Please refer to image 3, the conditioning tank body 1 also includes a first conditioning chamber 15 and a second conditioning chamber 16, the first conditioning chamber 15 and the second conditioning chamber 16 are separated by a partition wall 5, and the bottom of the partition wall 5 is provided with a wall that communicates with the first conditioning chamber 15. and the channel 51 of the second conditioning chamber 16, the height of the top surface of the partition wall 5 is lower than the height of the top surfaces of the first conditioning chamber 15 and the second conditioning chamber 16. By setting the first conditioning chamber 15 and the second conditioning chamber 16, when the gas is introduced to stir the mud, only the pool of the first conditioning chamber 15 is stirred, and the second conditioning chamber 16 is convenient for sedimentation and precipitation of supe...

Embodiment 3

[0039] Another embodiment provided by the present invention differs from Embodiment 1 only in that: Please refer to Figure 4 A decanter 6 for discharging the supernatant liquid in the conditioning tank body 1 is provided at the water outlet 13 . By setting a decanter 6 at the water outlet 13 in the conditioning tank body 1, the supernatant liquid in the conditioning tank body 1 is discharged in time through the water decanter 6, which further helps to adjust the mud in the conditioning tank body 1. Concentration: By adjusting the concentration of the mud in the conditioning tank body 1 in time, it is helpful for the deep dehydration of the subsequent filter press. The description of the value is that the decanter 6 can also adopt the existing conventional technology, preferably a rotary decanter. The description of the value is that the effluent discharged from the decanter 6 can be further introduced into the sedimentation tank to carry out the next step. Sedimentation tan...

Abstract

The invention provides a mechanical dehydration multifunctional mud conditioning pond for processing polluted bottom mud of rivers and lakes, which includes a conditioning pond body, which is provided with a slurry inlet, a slurry outlet and a water outlet, and the conditioning pond body is close to the slurry outlet An air inlet pipe is arranged at the center, and a plurality of ventilation holes are arranged on the air inlet pipe, and the plurality of air holes are arranged on the air inlet pipe in different directions. The mechanical dehydration multi-functional mud conditioning pool for treating river and lake polluted bottom sludge of the present invention realizes stirring the mud in the conditioning pool by ventilating the body of the conditioning pool, which can prevent the mud from settling and hardening, and avoid mud from accumulating at the bottom of the pool for a long time, effectively The storage capacity of the conditioning tank body is guaranteed, and at the same time, it also plays the role of noise reduction and can adjust the mud concentration in the conditioning room body.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a mechanical dehydration multifunctional mud conditioning pond for treating polluted bottom sludge of rivers and lakes. Background technique [0002] With the advancement of social science and technology, the pollution of rivers, lakes and other water bodies is serious, especially the river sediment, which contains a large amount of polluting substances, especially persistent refractory organic substances that cause disease (cancer) and destroy ecology. , Heavy metal ions seriously exceeding the standard. These harmful substances will affect human health and damage the natural environment and ecosystem through the accumulation and expansion effect of the food chain. The sediment pollution of rivers and lakes is mainly caused by human factors. Pollutants enter the water body through atmospheric deposition, wastewater discharge, rainwater leaching and scouring...
