Problems solved by technology

[0009] ③ The method recommended by the U.S. Environmental Protection Agency to treat Tl-containing wastewater is mainly to use activated alumina and ion exchange for adsorption and separation, but the cost is very high, and it is difficult to popularize and apply it in the treatment process of a large amount of Tl-containing wastewater
[0010] Other Tl purification methods include ultrafiltration, reverse osmosis, and electrodialysis, all of which are difficult to apply in actual industrial production due to high material costs and high maintenance costs.

Embodiment 1

[0050] A treatment method for thallium-containing wastewater of the present invention, such as figure 1 shown, including the following steps:

[0051] (1) Enter the clear liquid of thallium-containing wastewater into the adjustment tank, lift the thallium-containing wastewater to the pH adjustment tank through a centrifugal pump, and add 5% milk of lime (calcium oxide solution) in the pH adjustment tank to adjust the pH to 10.5.

[0052] (2) The mixed solution whose pH was adjusted in step (1) was discharged into the flocculation tank, and anionic PAM was added to carry out the flocculation reaction for 10 minutes.

[0053] (3) Discharging the mixed solution after the flocculation reaction in step (2) into a thickener for solid-liquid separation.

[0054] (4) Take the clear liquid after solid-liquid separation in step (3) and discharge it into the mixing tank, add an electrochemical thallium removal accelerator into the mixing tank, use aeration to mix to obtain a mixed solut...

Abstract

The invention discloses a treatment method of thallium-containing wastewater, and belongs to the field of wastewater treatment. The treatment method specifically comprises the following steps: adjusting the pH value of thallium-containing wastewater to be alkaline, then carrying out solid-liquid separation, and obtaining a supernatant; adding an electrochemical thallium removing accelerator in the supernatant to be mixed to obtain a mixed solution; carrying out an electrochemical reaction and aeration treatment on the mixed solution and adding a coagulant to carry out flocculation, then performing the solid-liquid separation. The treatment method disclosed by the invention has stability and high efficiency, low treatment cost, simple technological process and easy implementation of automatic control.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to the technical field of thallium-containing heavy metal wastewater treatment, and specifically relates to a treatment method for thallium-containing wastewater. Background technique [0002] Thallium (Tl) is a highly dispersed rare heavy metal element, which is widely used in high-energy physics, superconducting materials, medicine and health, aerospace, electronics, communications, military industry and chemical catalytic materials and other fields. However, thallium is a typical poisonous element, and its poisonous effect on mammals far exceeds that of conventional heavy metals such as Hg, As, Cd, Pb, Sb, etc., and thallium is also accumulative, and its distribution in the organism is extremely fast, and its elimination is very slow , which can cause continuous damage to organisms. Thallium can participate in the water cycle, enter the human body through the food c...
