Embodiment 2

[0051] Such as figure 1 , 7 As shown, on the basis of the foregoing embodiments, the present invention is provided with a fourth drive motor 20, a transmission shaft 21, a first gear 22 and a second gear 23 in the concentrating chamber 4; the first gear 22 is keyed to the outer wall of the concentrating cylinder 10 ; The transmission shaft 21 driven by the fourth drive motor 20 is rotated and installed in the concentration chamber 4 , and the main shaft is keyed to the second gear 23 ; the second gear 23 is meshed with the first gear 22 .

[0052] In an optional embodiment, the inner wall of the concentration chamber 4 is provided with a support seat 24; the support seat 24 is located on the side of the second gear 23 away from the first gear 22, and the support seat 24 is provided with a support groove 26; the support groove 26 is provided with a third gear 25 for rotation; the third gear 25 is meshed with the second gear 23 .

[0053] In the present invention, the first ge...

Embodiment 3

[0055] The present invention also proposes a waste liquid heavy metal treatment and recovery process, including the device in the above embodiment, the steps are as follows:

[0056] S1. Pour the waste liquid into the recovery chamber 2. The filter belt 5 filters out the large-volume metal particles in the waste liquid. The filter belt 5 rotates to move the metal particles to the outside of the housing 1. Under the impact of the high-pressure spray gun 27, the metal moves To collection box 29, filter belt 5 is cleaned and dredged simultaneously;

[0057] S2, the waste liquid falls on the metal adsorption roller 6 along the material guide plate 28, controls the magnetism of the metal adsorption roller 6, and absorbs and recycles the small-volume metal particles in the waste liquid;

[0058] S3, waste water enters the treatment chamber 3, and purifiers (acid-base regulators, sedimentation agents and complexing agents) are added to the treatment chamber, and through the action of...

Abstract

The invention relates to waste liquid heavy metal treatment and recovery equipment and the process thereof, and relates to the field of environmental protection. The equipment comprises a shell, a filter belt, a metal adsorption roller, a concentration cylinder, a water pipe, a condenser, a heating piece and vacuumizing equipment; a recovery chamber is arranged above the treatment chamber; a concentration chamber is arranged on one side of the treatment chamber; a filter belt is arranged below the water inlet of the recovery chamber; a metal adsorption roller is arranged below the filter belt;a concentration cylinder is rotationally arranged in the concentration chamber; and a condenser is communicated with the air outlet end of the concentration cylinder. The equipment further comprisesa first filtering assembly and a second filtering assembly. According to the invention, the filter belt and the metal adsorption roller are matched to classify and recover part of heavy metals in thewastewater according to the volume; the wastewater is subjected to secondary filtration through the first filtering assembly and the second filtering assembly; water and volatile substances in the wastewater are separated by utilizing the principle that the boiling point of the solution is reduced under low pressure; the filter effect is good, heavy metals are thoroughly recycled, the wastewater utilization rate is high, and more energy is saved and environment is protected.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a waste liquid heavy metal treatment and recovery equipment and process. Background technique [0002] With the rapid development of industry and the acceleration of urbanization, the heavy metal pollution in my country's soil is becoming more and more serious, and the restoration and treatment of heavy metal-contaminated soil has become urgent. At present, a series of heavy metal soil remediation technologies have been proposed at home and abroad, which are mainly divided into physical remediation technology, phytoremediation technology, microbial remediation technology and chemical remediation technology. The original meaning of heavy metals refers to metals with a specific gravity greater than 5 (generally speaking, metals with a density greater than 4.5 grams per cubic centimeter), including gold, silver, copper, iron, lead, etc. Heavy metals accumulate in the human bo...
