3. the characteristics of copper mine acid waste water
Copper mine acid waste water caused waste water after biological dump leaching essentially from copper mine, has following features：
（1）Between copper mine acid waste water pH is 2~4, contain various ions.In addition, also contain in these waste water
The organic matter such as suspension and mineral oil.
（2）Wastewater flow rate is big, time of flow length.
（3）Drainage point disperses, and water quality and water fluctuation are big.
4. waste water treatment process selects
According to the principle of " the dirty shunting of rain, remove contamination shunting, dual treatment, multi-purpose water ", the waste water after processing realizes gradient
Reuse, realize the overall goals of zero-emission.The acid waste water of this engineering plant area enters acidity in the lump with the early-stage rainwater in sulfuric acid area
Waste water processing station processing, meets first after processing《Copper, nickel, cobalt emission of industrial pollutants standard》(GB25467-2010) table 3 is marked
It is accurate and《Hunan Province's industrial wastewater thallium pollution thing discharge standard》（DB43/968-2014）, processing rear portion is allocated as Sewage Disposal
Medicament preparation water, then fully recovering supplements water in circulating cooling after acid waste water advanced treating, not outer to arrange.
Because, mainly containing acid, containing arsenic, containing heavy metal etc., the sewage treatment process of design is with this in the acid waste water of this engineering
Three pollutants remove target to be main, and remaining other pollutant load is less can to pass through the membrane technology of advanced treatment unit
Removed.
The waste water treatment process that this engineering is finally selected is：
（1）H in acid waste water2SO4Neutralized using milk of lime；
（2）Hydroxide precipitation method is selected in the removal of heavy metal ion in acid waste water, is controlled by feeding lime breast
The pH value of waste water processed, is neutralized using multistage, in OH-In the presence of make heavy metal generation insoluble matter precipitation and remove；
（3）Arsenic in waste water uses lime-ferrous method, by add ferrous salt and through aeration agitation, make it fully mixed
Reaction is closed, and the trivalent arsenic of part is oxidized to pentavalent arsenic using the oxygen in air, is removed through precipitation；
（4）Thallium in waste water is aoxidized, monovalence thallium using pre-oxidation coagulant sedimentation by adding sodium hypochlorite
Trivalent thallium is oxidized to, trivalent thallium can generate the thallium hydroxide sediment for being insoluble in water in the basic conditions, then dosing coagulant
Precipitation removes；
（5）Water outlet after neutralization precipitation carries out further removing metal ion again through electric flocculation workshop section, it is ensured that at heavy metal
Manage suspension up to standard, then further to be gone in water removal through flocculation sediment；
（6）Advanced treating further carries out desalination reuse by ultrafiltration and reverse osmosis membrane technology.
