Abstract
The invention discloses a method for processing gold mine wastewater. The method comprises the steps of reagent adjusting, coagulation processing, secondary coagulation processing, irradiation and precipitate. The foreign material in the waste water is existed in suspension, dissolving cavity and high-molecular states. The method has certain degree of stability, a flocculating agent and a flocculating agent are added, the cavity and suspension impurity in the waste water can be effectively reduced, a flocculating constituent is rapidly aggregated, and can be rapidly removed from water, through precipitation, the processed waste water can greatly reduce the pollution and destroy on natural environment, and effectively solve the waste water discharge problem. The method has the advantages of good processing effect, high processing efficiency and simple process flow, and can completely realize industrial application.
Description
Technical field
The present invention relates to Pollutant Treatment technical field, be specifically related to the process of a kind of gold mine waste
Method.
Background technology
Gold mine waste is mainly by the most waste water composition of digging and ore-dressing technique two, beanstalk water quality and water
Measure and change with mining area soil lithology matter, mining method, volume of production and committee joint.Main in waste water
Polluter is the suspended material being made up of silt, clay, humus and bark and grass roots, secondly
It it is organic substance etc..Though this waste water has a certain degree of stability, but in discharge process not
Easily precipitation. making natural water muddy, colourity increases.Meanwhile, to swimming in aquatic ecosystem
Flora, floating debate fauna, the sacrificial biota in the end and cause impact according to group and destroy.Gold mine gives up
Water water quality belongs to multistage coarse dispersion system.Its dispersed substance is the silt particle particle of different-grain diameter, point
Dispersion media is water.The clay water lazy limb limb group formed is by limb rib adsorption layer, disperses a layer group
Become. owing to all adsorbing substantial amounts of anion on each ten glue edge surfaces so that same between micelle
Property electric charge is mutually exclusive and is difficult to precipitate.The composition of different waste water is different, and all waste water are all in weak
Alkalescence, various electrical conductivity of waters are the highest, and the difference between water quality is relatively small.Various water
In ion be mainly calcium, magnesium cation and sulfate radical and bicarbonate anion, other metal
The content of ion is the highest.What content difference was maximum is turbidity and the suspension content of waste water.
Owing to current gold mine can use Cyanide Process during extracting, thus can produce
Raw substantial amounts of cyanide wastewater, these waste water have certain toxicity, can cause environment huge
Harm.
Summary of the invention
It is desirable to provide the processing method of a kind of gold mine waste fast and efficiently, to solve
The waste water problem to environment.
The present invention is achieved by the following technical programs:
A kind of processing method of gold mine waste, the method comprises the following steps:
A, reagent regulate: add strong reagents, strong base reagent, catalyst, control in waste water
In course of reaction processed, the pH value of waste water is 8-9, and the response time is 30-35min；
B, coagulation: stir reacted waste water according to the linear velocity of regulation clockwise, and
Add flocculating agent, waste water is put into standing 15-20min in sedimentation tank；
C, second coagulation: according to the speed stirring waste water of regulation and in waste water after despumation
Add flocculant, place into standing 20-25min in sedimentation tank；
D, irradiation: the supernatant of waste water is carried out ultra violet lamp, irradiation time is 15-20min；
E, precipitation: in the waste water that irradiation completes, add zinc sulfate, make cyanide with zinc cyanide
Form Precipitation, then be acidified with sulphuric acid, reacted rear waste water and can send in pond again
Utilize or directly discharge.
One during strong reagents is sulphuric acid, hydrochloric acid in described step a.
Catalyst in described step a be concentration be the copper-bath of 55-60%.
Strong base reagent in described step a is sodium hydroxide solution.
Stirring linear velocity in described step b is 15-25m/s.
Flocculating agent in described step b is the one in ferric chloride, ferrous sulfate.
Flocculant in described step c is polyacrylamide.
The concentration of the sulphuric acid used in described step e is 80-85%.
The beneficial effects of the present invention is: owing to the foreign material in waste water are in suspended, molten in water
Chamber and polymer state exist. and having a certain degree of stability, therefore this method is by adding
Flocculating agent and flocculant, effectively reduce the cool qualitative of cavity and suspended impurity in waste water, make it
Can quickly be gathered into thicker floccule body, in order to remove from water rapidly, by heavy
Form sediment, separate and waste water after treatment can significantly be reduced natural ring in discharge
The pollution in border and destruction, effectively solve the emission problem of waste water, and this method process effect
The best, treatment effeciency is high, technological process is simple, is fully able to realize commercial Application.
