Description

Crane compound for treatment of electroplating wastes that a kind of photocatalysis effect is good and preparation method thereof

Technical field

The present invention relates to water treatment agent technical field, particularly relate at the crane electroplating wastewater that a kind of photocatalysis effect is good Reason agent and preparation method thereof.

Background technology

Along with the sustainable growth of China's economy, following one period China's construction machinery industry still in high speed development Phase, particularly crawler crane industry promise well." the industry restructuring guidance list (2011 that National Development and Reform Committee promulgates This) " in explicitly point out, 400 tonnes and above crawler crane are chosen as " encouragement class " product as new industry, imply that shoe Band crane promise well, so causing increasing enterprise to join Crane Industry.Owing to crane mostly is room Outer work, therefore particularly payes attention to its facing operation, including eliminating rust, electroplate, spraying paint, the most also produces a large amount of waste water, And containing substantial amounts of metal ion in waste water, such as Cu²⁺、Ni²⁺、Cr³⁺、Zn²⁺、Pb²⁺、Ag⁺、Cd²⁺Deng, toxicity is very big, especially Be plating be one of with serious pollution industry, if do not recycled the waste also resulting in resource, the health of people in serious threat Health and Living quality.

The at present both at home and abroad most widely used chemical precipitation method that is still of electroplating waste water treatment technology, but treatment effeciency is low, heavy The quantity of slag is big, easily cause secondary pollution etc..Though the macromolecular heavy metal chelating agent developed in recent years has good treatment effect, but Expensive, it is difficult to be accepted by Chinese market.Utilize the developmental research of natural polymer heavy metal containing wastewater treatment agent increasingly Being concerned, " preparation of amino modified starch heavy metal containing wastewater treatment agent and application " author utilizes amino modified starch to process reality Heavy metal ion in waste water, clearance close to 100%, but, the method be use These powdered adsorbents process waste water, locate afterwards Science and engineering skill is more complicated.As used granulating technique to make granular adsorbent, then process technique relatively simple, and consume power Few.

" preparation of a kind of heavy metal containing wastewater treatment agent and the characterization research of applied research-granular wastewater treatment agent " literary composition with Modified dicyanodiamide is raw material, uses the granulating technique rolling granulation to prepare the graininess waste water treating agent of function admirable. Result shows: the granular wastewater treatment agent of preparation removes Pb²⁺Ability can reach 112.28mg/g, the structure of water treatment agent with change Property the structure of natural apatite compare, there is not great change, preferably maintain every property of the natural apatite of modification Energy.Simultaneously because the addition of additive, define the cohesive body of abundant hole and high intensity.Although literary composition being with relatively inexpensive The natural non-metallic mineral such as natural apatite remove the heavy metal ion in waste water as adsorbing material, but consume too much Natural non-metallic mineral and belong to non-renewable resources, do not meet the requirement of environment protecting and power-saving, the most numerous processing enterprises heap The utilization rate of solid waste of long-pending excess is the highest, therefore can effectively use and in addition modified with Substitute For Partial natural phosphorus ash Stone, adds the binding agent of adaptation with the waste water treating agent that prepare function admirable, efflorescence degree is low, absorption property is strong simultaneously. The most not only solved a large amount of fixed-end forces difficult problem improperly but also low etc. for existing waste water treating agent cost high disposal weak effect intensity Defect provides strong effective solution.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that the crane plating that a kind of photocatalysis effect is good Waste water treating agent and preparation method thereof.

The present invention is achieved by the following technical solutions:

The crane compound for treatment of electroplating wastes that a kind of photocatalysis effect is good, is prepared by the raw materials in: apatite 36- 38, coral sand 20-22, Folium Camelliae sinensis ground-slag 13-15, Retinervus Luffae Fructus 10-12, Semen Sesami skin 15-17, tapioca 6-8, ethylenediamine 5-7, water Glass 3-5, titanium dioxide 2-4, methyl methacrylate 7-9, suitable quantity of water.

The manufacture method of the crane compound for treatment of electroplating wastes that described a kind of photocatalysis effect is good, comprises the following steps:

(1) Folium Camelliae sinensis ground-slag, Retinervus Luffae Fructus, Semen Sesami skin are dried and are crushed, add mass fraction be 10-20% soda ash solution in Soaking 24 hours at 70-90 DEG C, use deionized water rinsed clean, drain drying, addition methyl methacrylate, titanium dioxide surpass Sound grinds 20-30 minute, dries to obtain modified mixed powder；

(2) by coral sand in 750-810 DEG C of high-temperature process 10-20 minute, spray after being cooled to room temperature mass concentration be 98% dense Sulfuric acid solution sulfonation in a nitrogen environment processes 15-20 minute, filtration with hot wash to without SO4^2–, add tapioca, second Diamidogen magnetic agitation 2-3 hour, dries；

(3) apatite is calcined 2-3 hour in the oxygen atmosphere of 200-300 DEG C, be cooled to room temperature and pulverize, obtain activation apatite Powder body, adds step (2) material and is ground, and adds step (1) material and the mixing of other residual componentss, sprays into 10% moisture, make Grain, drying, finally in 700-750 DEG C of roasting 15-20 minute, discharging.

The invention have the advantage that the present invention adds Substitute For Partial apatite in raw material to not only reduce modified for coral sand The yield of natural apatite is also effectively improved the micropore quantity adsorptivity of inorganic agent and strengthens；The present invention is also by tealeaf residue simultaneously Add in raw material as bonding agent and the effective chemosorbent of compatibility after powder, Retinervus Luffae Fructus, Semen Sesami skin are organically-modified, with organic dirt The dye good adsorption rate of the thing compatibility is high, after after pelletize, high-temperature roasting PROCESS FOR TREATMENT, define abundant hole and high intensity Cohesive body, and owing to the binding agent of addition forms compound with other material in roasting process, it is suppressed that natural ground phosphate rock exists The phase transformation that different temperatures interval occurs, reduces internal stress and produces, reduce efflorescence degree, and the inorganic agent utilizing the present invention to prepare can Effectively reducing the COD in crane electroplating wastewater, photocatalysis effect is good, and preparation technology is simple, it is easy to operation.
