Problems solved by technology

[0003] At present, the treatment of wastewater mainly adopts the method of natural evaporation of wastewater. This method takes advantage of the local natural conditions, reduces the cost of wastewater treatment, and realizes zero discharge of radioactive wastewater. The concentration of various ions, organic matter and nitrogen and phosphorus compounds in the wastewater gradually increases.
It pollutes the surrounding environment and does not meet the requirements of the company and local government for building green mines

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 A deodorization method for in-situ leaching uranium mining wastewater is shown, which is suitable for CO 2 +O 2 In-situ leaching of uranium mines, including the following steps:

[0030] (a) Install aeration device 4

[0031] In the evaporation pool 5, a circle of aeration device 4 is arranged around the inner edge of the evaporation pool 5. The aeration device 4 is 2-5m away from the inner edge of the evaporation pool 5, which is convenient for installation and recycling. Such as figure 2 As shown, the aeration device 4 includes an aeration tube 8 , a bracket 9 and a reticulated tube 10 . The aeration tube 8 is spirally fixed on the bracket 9, and the height of the bracket 9 is 20 to 50 cm, so that the aeration tube 8 is kept at a certain distance from the sludge at the bottom of the evaporation pool 5 t...

Abstract

The invention relates to the technical field of wastewater deodorization and particularly discloses an in-situ leaching uranium mining mine wastewater deodorization method. The method comprises the following steps: (a) mounting an aerating apparatus; (b) delivering compressed air; (c) adding an algae removal agent. According to the method disclosed by the invention, wastewater in an evaporation pond is treated, anaerobic bacteria in the wastewater can be inhibited and killed, and odor produced in the normal metabolism process of green alga in the wastewater can be eliminated. The method has relatively high social value, environmental-friendly value and ecological value.

Description

technical field [0001] The invention belongs to the technical field of wastewater deodorization, and in particular relates to a method for deodorizing wastewater from in-situ leaching uranium mining mines. Background technique [0002] In-situ leaching uranium mining technology is a new uranium mining process integrating mining, dressing and smelting. Compared with conventional mining and smelting methods, this method does not require the construction of tailings dams and waste rock dumps, and is an environmentally friendly uranium deposit mining method. The treatment method of the waste water generated during its production and operation is to discharge it into the evaporation pond for natural evaporation. In situ leaching mine wastewater mainly comes from leachate treatment process and well washing process. For CO 2 +O 2 In situ leaching mines, the main sources of wastewater are resin-poor transition wastewater, part of the sedimentation mother liquor with low uranium co...
