Description
Technical field
The utility model belongs to technical field of sewage, is specifically related to a kind of electroplating and complexing wastewater zero discharge treatment unit.
Background technology
In electroplating industry, complexing waste water mainly to lose in the waste water of the operation such as plate, electroless copper plating discharge containing cupric ion and complexing agent as NH
4oH, EDTA and soluble tartrate etc.Complexing Cu in waste water ion and complexing agent form a kind of more stable complex compound, are more unmanageable a kind of complex compounds in electroplating and complexing waste water.Some wiring board corporate bosses will be recycled, and copper is converted into CuSO
4, CuO, Cu, ammonium sulfate or ammonium chloride etc., some enterprises are disposed to Sewage treatment systems process.
First should consider to destroy complexing action to the process of complexing waste water (EDTA, ammonia alkali copper), cupric ion can be made free out.At present in actual motion, adopt multiple method contact break, be now summarized as follows:
Method one: adjust pH value contact break (adjusting waste water PH to acid about 2 contact breaks);
Method two: redox contact break (iron filings reaction, NaClO);
Method three: ion-exchange-electrolytic process contact break method contact break;
Method four: chemical agent displacement contact break (Na
2s, FeCl
3, special medicaments etc.).
In above four kinds of methods, acid liquid (HCl, H in method one
2sO
4) adjust complexing waste water pH value to 2 ~ 3, Cu
2+dissociate out from complex compound, broken chromium is respond well.But because of many in alkalescence containing the former water of network waste water, be adjusted to when acid PH is 2 ~ 3 and consume a large amount of acid solutions, also need after contact break to be adjusted to alkaline PH again at about 8-9 precipitated copper, consume again a large amount of alkali lye, processing costs is higher, therefore uses not extensive.
Iron filings-Polyferric Sulfate method, in acid condition PH=3 is commonly used in redox contact break in method two, with iron filings Fe and ferrous ion Fe
2+reduction, reaction about 20 ~ 30min, Fe
2+by Cu
2+eDTA complex compound in Cu
2+be reduced into Cu
+, because of Cu
+not easily be combined with EDTA in the basic conditions, therefore in the basic conditions, generate Cu
2o, with Fe (OH)
2, Cu (OH)
2coprecipitated.Because of the iron filings of iron filings-Polyferric Sulfate method contact break, easily fouling is agglomerating in the reactor, affect the normal operation of equipment, and iron filings upgrades labour intensity greatly, hamper the application of this kind of method.And adopt clorox contact break to be side reaction occurs with cyanide wastewater when contact break, contact break is had certain effect, but when only having sewage to contain cyanogen, this method is just of practical significance.
Ion-exchange-electrolytic process in method three easily makes that exchange resin is saturated, complex compound easily makes exchange resin pollute or aging, the shortcoming such as electrolysis current consumption large, the heavy kind of process metal is single and seldom adopting because of the heavy metal of high density.
Employing in method four has the chemical agent of contact break effect as Na
2s, FeCl
3, special medicaments etc., medicine is easily buied, moderate, effective, application conditions loose, and in board wastewater, have application and popularization value, be also the method generally adopted in current board wastewater process.FeCl
3contact break is effective, but medicine has severe corrosive, and transport, storage, requirement is higher, employing also less.The kind that contact break special agent is developed now is a lot, most genus patented product, if ISX (insoluble cross-linking starch xanthate) is the water conditioner that the seventies grows up, can precipitate most of heavy metal, PH range of application is wide is 3 ~ 11, and precipitation is fast; TMT (three mercapto triazine trisodium salts) is a kind of novel heavy metal precipitation agent of nearest U.S. exploitation; S946 is also a kind of novel treatment agent.Adopt Na
2s process complexing waste water is the selection of most wiring board scale wastewater treatment, Na
2s is not only used for process complexing waste water, and to be used for process non-complexing waste water copper removal effect be also good, S
2-in precipitable complex compound, cupric ion reaction generates CuS.But the shortcoming of this method to destroy EDTA complex molecules chain, is still present in waste discharge with activated state, in the water of discharge, there is the possibility regenerating complex salt, cause difficulty to the advanced treatment of waste water and reuse.
