Description
Technical field
The present invention relates to the processing method of a kind of industrial wastes, be specifically related to the processing method of a kind of contained waste liquid.
Background technology
The source of copper-bearing industrial wastewater mainly produces in smelting, intermetallic composite coating, machine manufacture, mine wastewater and other industrial processes, wherein the waste water content of copper ion with intermetallic composite coating, electroplating facility discharge is the highest, and waste water copper content is up to tens to hundreds of milligrams per liter. Copper-containing metal ion enters water body, can have a strong impact on the quality of water. Investigation shows, abnormal flavour can be produced when cupric in water, cannot drink more than 15 mg/litre, in irrigation water, the critical concentration of rice hazard is 0.6 mg/litre by copper sulfate, if using copper-containing wastewater irrigated farmland, copper accumulates in soil and crops, can cause the undergrowth of crops especially Oryza sativa L. and Fructus Hordei Vulgaris, and grain and seed can be polluted, cause ecological disruption and be detrimental to health.
Current domestic more common Copper Wastewater Treatment Technologies mainly has chemical precipitation method, electrolysis, absorption method, ion exchange and ion chelating method; The plurality of advantages such as chemical precipitation method chemical Treatment copper-contained electroplating waste water has technology maturation, small investment, processing cost is low, strong adaptability, convenient management, automaticity are high, it it is the conventional treatment method of copper-containing wastewater, but produce copper-contained sludge after processing, if mud does not obtain appropriate process also can produce secondary pollution, use chemical Treatment copper-containing wastewater, it is first necessary to abolish chelating agent, copper is made to be present in cleaning waste water in the form of an ion, otherwise forming copper complex, the water outlet copper content after process is still significantly high; Electrolysis flow process is simple, and floor space is little, and the metal purity of recovery is also high, but power consumption is big, and wastewater treatment capacity is little; Absorption method Treatment of Copper waste water, adsorbent wide material sources, cost is low, easy to operate, advantages of good adsorption effect, but the service life of adsorbent is short, regeneration difficulty, it is difficult to reclaim copper ion; Ion exchange process is very simple, and equipment is also uncomplicated, and selective extraction metal ion has good effect, but resin exchange capacity is limited, and resin is relatively costly; The Stability of Chelate formed is high, and sludge settling is fast, and the impact that trapping effect is not coexisted by alkali and alkaline earth metal ions, also not by the impact of pH value change, its weak point is similar to chemical precipitation method, eventually produces sludge containing heavy metal, if dealing with improperly, secondary pollution can be produced.
