Description
Technical field
The invention belongs to field of waste water treatment, and in particular to a kind for the treatment of process of copper-containing wastewater.
Background technology
The source of copper-bearing industrial wastewater is mainly raw in smelting, intermetallic composite coating, machine manufacture, mine wastewater and other industry
What production generated in the process, wherein with the waste water content of copper ion highest that intermetallic composite coating, electroplating facility discharge, waste water copper content is reachable
Tens to hundreds of milligrams per liter.Copper-containing metal ion is discharged into water body, can seriously affect the quality of water.Investigation shows to work as water
It will produce peculiar smell when middle cupric, cannot be drunk more than 15 mg/litres, copper sulphate is to the critical dense of rice hazard in irrigation water
Degree is 0.6 mg/litre, if with copper-containing wastewater irrigated farmland, copper accumulates in soil and crops, can cause crops especially
The undergrowth of rice and barley, and grain and seed can be polluted, cause ecological disruption and be detrimental to health.
Domestic more common Copper Wastewater Treatment Technologies mainly have chemical precipitation method, electrolysis, absorption method, ion to hand at present
Change method and ion chelating method；Chemical precipitation method chemical Treatment copper-contained electroplating waste water has technology maturation, small investment, processing cost
Many advantages, such as low, adaptable, management convenience, high degree of automation, it is the conventional treatment method of copper-containing wastewater, but handles
After generate copper-contained sludge, if sludge does not obtain appropriate processing and also will produce secondary pollution, with chemical Treatment copper-containing wastewater,
Complexing agent must be abolished first, so that copper is present in the form of an ion in cleaning waste water, otherwise can be formed copper complex, treated
It is still very high to be discharged copper content；Electrolysis flow is simple, and floor space is small, and the metal purity of recycling is also high, but power consumption is big,
Wastewater treatment capacity is small；Absorption method Treatment of Copper waste water, adsorbent derives from a wealth of sources, at low cost, easy to operate, and adsorption effect is good, but
The service life of adsorbent is short, and regeneration is difficult, it is difficult to recycle copper ion；Ion-exchange process is very simple, and equipment is also uncomplicated,
Selective extraction metal ion has good effect, but resin exchange capacity is limited, and resin cost is higher；The chelate of formation is steady
Qualitative height, sludge settling is fast, and traps effect and do not coexisted and influenced by alkali and alkaline earth metal ions, the shadow also not changed by pH value
It rings, shortcoming is similar to chemical precipitation method, finally will produce sludge containing heavy metal, if dealing with improperly, will produce secondary dirt
Dye.
Chinese patent application CN102531118 A disclose a kind of remover of Treatment of Copper waste water, the remover, by mine
