Description
Technical field
The present invention relates to a kind of reclamation of solid wastes makees the preparation method of adsorbing material, more particularly to a kind of converter slag containing vanadium and titanium oxides
The preparation of base zinc ferrite catalyst and the method for processing dyeing waste water.
Background technology
Slag is a kind of trade waste produced in steelmaking process, accounts for the 15% ~ 20% of crude steel yield.The group of slag
Into oxide that is complex, being formed after mainly containing the oxidation such as steel scrap and Al, Si, Mn contained by molten iron in slag, add
Calx, the slag former such as fluorite, iron scale, sintering deposit, iron ore as coolant or oxidant etc., the stove material being etched
The components such as material and furnace lining material, the deoxidation productss of alloy, the silt in the desulfurization product and metal charge of slag.The density of slag
About：1700-2000kg/cm3, heat stability is good, the strong adaptability to pH value.The main chemical compositions of slag are CaO, SiO2
、Fe2O3、Al2O3、MnO 、MgO 、P2O5, free radical CaO be f-CaO.Due to the difference of process for making, steel grade etc., slag
Appearance difference is larger, and color also can change with the change of basicity, basicity from low to high, slag difference gray, taupe gray and
Canescence.China produces steel per year up to 500,000,000 tons at present, produces about 80,000,000 tons of slag, 300,000,000 tons of the slag that also stores up, China's steel per year
About 400,000,000 tons of the scum amount of banking up, takes up an area about 20,000 mu.If long-term stack, the land resource of preciousness is not only taken up, but also can be dirty
Dye environment.
Dyeing waste water is mainly derived from dyeing and printing process process.Dyeing and printing process is broadly divided into pretreatment（Singe, desizing, boil
Practice, bleach and mercerising）, dyeing, the operation such as stamp and arrangement.Wherein, pretreatment stage will be discharged desized wastewater, kiering and be given up
Water, bleaching effluent and mercerizing waste water, dyeing process can discharge dyeing waste-water, and revenue stamp process can discharge printing waste water and soap lye is useless
Water, arranging process can discharge arrangement waste water, and the waste water quality feature of each operation differ.Totally see, dyeing waste water has
Have that displacement is big, colourity is high, stink is big, COD contents are high, complicated component and changeable the characteristics of；Additionally, also containing many in dyeing waste water
Kind bio-toxicity is larger and is difficult to the material that degrades；Moreover, in dyeing waste water, COD is much higher compared with BOD, so which can
Biochemical is also poor.According to relevant document report, sometimes up to more than 4000 times, COD is up to 2000- for color degree of dyeing waste water
3000mg/L, and Alkali reduction popular in recent years and sea island filament technique, make COD in waste water be increased to tens of thousands of mg/L therefore again, print
Dye waste water is one of putative intractable organic industrial sewage.
Conventional Methods of Color Removal of Dyestuff Effluent has absorption method, flocculence, oxidizing process, electrolysis and biochemical process etc. at present,
Wherein absorption method is the common process of decoloring dye waste water, and the high processing cost of activated carbon adsorption makes its popularization and application be subject to very
Big restriction, the adsorbing material for finding high efficiency low cost at present become the focus of scholars' extensive concern.
More popular to steel slag utilization new way research at present is to make adsorbing material to process waste water.But slag is inhaled at present
Attached dose is substantially directly using slag porous, and specific surface area is big, and slag is directly used as absorption by the negatively charged characteristic in surface
Material process effluent containing heavy metal ions.Due to containing heavy metal ion such as ferrum, lead, hydrargyrum, chromium, such as directly making adsorption material in slag
How material, prevent the heavy metal ion dissolution in slag, bring secondary pollution to handled waste water, while when adsorbent adsorbs
Saturation is reached, slag just loses the effect of adsorption bleaching, need, by the process of the methods such as high temperature, to make to be adsorbed in slag surface
Dye molecule is degraded, and so brings secondary pollution.Therefore, how scale, non-secondary pollution, high added value recycling steel
Slag is using the difficult problem for facing.
