Embodiment Construction

[0039] 1. Grading sedimentation: The sewage is graded and sedimented according to the thickness of the sediment particles. The equipment used is a classifier and a radial flow sinking and floating tank

[0040] ①The working principle of the classifier, the sewage enters the sedimentation area of ​​the classifier after being rectified and energy-dissipated from the side of the classifier, and the coarse sand settles to the bottom by gravity, and then is conveyed to a high place inclined at 15° by the rotating screw shaft at 5 revolutions per minute. Dehydration, the sewage is discharged from the overflow port.

[0041] ② Radial flow sinking and floating tank, the sewage enters from the center of the tank because the diameter is much larger than the depth. The water flows radially to the surroundings, and the sewage after sedimentation is discharged back to the solid collection tank. The sludge slowly enters the sludge hopper in the center of the pool under the action of the m...

Abstract

The invention relates to a method for treating wastewater in a fluorite dressing plant. The method comprises the following treating steps: fractionated precipitation, electrocoagulation, air floatation and decontamination, advection-type precipitation, filtration of a treated solution and dehydration treatment of sediment. The method has the advantages of no addition of a chemical agent, low treatment cost, no secondary pollution, no regulation of pH value of wastewater and wide application range.

Description

(1) Technical field [0001] The invention relates to a sewage treatment method of a yingshi mineral processing plant. (2) Technical background [0002] The fluorite fine powder produced by fluorite beneficiation, as the basic raw material of fluorine chemical industry, has a history of half a century in China. In recent years, with the continuous advancement of science and technology and the improvement of social living standards. The application of fluorine chemical products is more and more extensive, which promotes the rapid development of fluorite mineral processing industry, but also brings water pollution. In recent years, under the environment that the country emphasizes energy conservation and emission reduction, the indicators for sewage discharge in the mineral processing industry have become more and more stringent, and the industry access standards for mineral processing enterprises have been improved. [0003] There are two existing sewage treatment methods for...
