Abstract
The invention discloses a remover for treating copper-containing wastewater and an application method for the remover. The remover consists of 25 to 80 mass percent of minerals and 20 to 75 mass percent of amine compounds, wherein the minerals is one or two of kaolin, sepiolite, montmorillonite, kieselguhr, zeolite, iron ore and manganese ore; and the amine compounds are one or two of (3-aminopropyl)triethoxysilane, aziridine and polyethyleneimine. The application method comprises the following steps of: (1) soaking the minerals and the amine compounds, which are crushed to have the granularity of 50-100 meshes in sulfuric acid for 1 to 2 days, and drying and activating at 105DEG C for 4 hours to obtain activated minerals; (2) adding the activated minerals into 10 to 500mg/L copper-containing wastewater in a proportion of 20-100ppm, and stirring for 1 to 3 hours; and (3) precipitating and separating. The minerals having large porosity and large specific surface area are aminated under the condition of the amine compounds, active sites combining copper ions are formed, the copper ions are firmly combined with the active minerals, and the removal rate of the copper ions in the wastewater is over 99.9 percent; and the combined minerals are acidized, and copper is recovered.
Description
Technical field
The present invention is a kind of remover and application method thereof of Treatment of Copper waste water, relates in particular to the waste water of Treatment of Copper amount at 10mg/L～500mg/L, belongs to field of waste water treatment in the environment protection.
Background technology
The source of cupric trade effluent mainly produces in smelting, metal processing, machine manufacturing, mine wastewater and other Industrial processes; Wherein the waste water content of copper ion with metal processing, the discharging of plating factory is the highest, and the waste water copper content can reach tens to every liter of hundreds of milligram.The copper-containing metal ion enters water body, can have a strong impact on the quality of water.Investigation shows, when producing peculiar smell during cupric in the water, surpasses 15 mg/litre and used with regard to unable to drink; Copper sulfate is 0.6 mg/litre to the threshold concentration of rice hazard in the irrigation water; If use the copper-containing wastewater irrigated farmland, copper accumulates in soil and farm crop, can cause the especially poor growth of paddy rice and barley of farm crop; And can pollute grain and seed, cause ecological damage and be detrimental to health.
At present domestic copper-containing wastewater treatment technology commonly used mainly contains chemical precipitation method, electrolytic process, absorption method, ion exchange method and ion chelating method; Chemical precipitation method chemical Treatment copper-contained electroplating waste water possess skills maturation, less investment, plurality of advantages such as processing cost is low, flexibility is strong, convenient management, level of automation height; It is the conventional treatment method of copper-containing wastewater; But handle the back and produce copper-contained sludge,, use the chemical Treatment copper-containing wastewater if mud does not obtain appropriate processing and also can produce secondary pollution; At first must abolish complexing agent; Copper is present in the Cleaning Wastewater with ionic species, otherwise can forms copper complex, the water outlet copper content after the processing is still very high; The electrolytic process flow process is simple, and floor space is little, and the metal purity of recovery is also high, but current consumption is big, and wastewater treatment capacity is little; Absorption method Treatment of Copper waste water, the sorbent material wide material sources, cost is low, and is easy to operate, advantages of good adsorption effect, but the work-ing life of sorbent material is short, and the regeneration difficulty is difficult to reclaim cupric ion; The ion exchange method process is very simple, and equipment is also uncomplicated, and the selective extraction metals ion has good effect, but exchange capacity of resin is limited, and the resin cost is higher; The inner complex stability that forms is high, and sludge settling is fast, and captures the influence that effect does not receive basic metal and earth alkali metal coexistence; The influence that not changed by the pH value, its weak point is similar with chemical precipitation method, finally can produce sludge containing heavy metal; If deal with improperly, can produce secondary pollution; For example, Zheng Huaili is at " the Cu in the CU2# heavy metal capturing agent removal waste water
2+Research " mentioned a kind of method of CU2# heavy metal capturing agent Treatment of Copper waste water; experimental result shows; in pH is 1-14 scopes, and churning time is 5min, after the CU2# heavy metal capturing agent is handled copper-containing wastewater when not adding flocculation agent; the content of its supernatant copper is lower than 0.3mg/L, the clearance of copper is reached 99.7%; Zhang Min etc. are in that " high molecular heavy metals flocculation agent MAC removes Cu
2+, go turbid performance " mentioned a kind of being that raw material has synthesized a kind of novel high polymer heavy metal flocculation agent sulfydryl acetyl chitosan (MAC) with chitosan, Thiovanic acid etc., having studied it and removed Cu
2+Mechanism, the result shows: MAC has the performance of copper removal, when MAC and HPAM are composite, Cu
2+Clearance can reach more than 98%.
Therefore; For overcoming the deficiency of prior art, invented a kind of remover of removing copper-containing wastewater, it is less relatively that the inventive method has added amount of chemical; Working cost is lower; Can one step of copper-containing wastewater of 10mg/L～500mg/L be dropped to below the 0.3mg/L, the copper removal rate is applicable to industrial production up to more than 99.9%.
