Description
Technical field
The present invention relates to a kind of preparation method and the application that process lead waste water adsorbent, belong to technical field of heavy metal wastewater treatment.
Background technology
In ecological water body environment, the main source of lead waste water is the sedimentation of leaded particle in water body in the industrial wastewater of the industry discharges such as plating, smelting, casting, agricultural chemicals, mining, dyestuff, oil, battery, machinery, printing and air.Battery industry is the main source of lead waste water, it is reported, often producing 1 battery and just cause plumbous loss to be 4.54 ~ 6810mg, is secondly that petroleum industry produces gasoline additive.Lead belongs to first kind water pollutant, and by national regulation, the total lead content of lead waste water must reach first kind pollutant maximum permissible concentration discharge standard at workshop floss hole, i.e. 1mg/L.Make a general survey of the treatment technology of lead waste water both at home and abroad at present, apply more, mainly contain compared with the technique of mature and reliable: chemical precipitation method, ion-exchange, electrolysis, absorption method, bioanalysis, membrane separation process etc.But the shortcomings such as these method ubiquity treatment effects are bad, cost is high.Therefore, find a kind of way of fine solution lead contamination, for the maintenance of good ecological environment, the urban ecological environment that especially industry is flourishing is very important.
Ardealite is the solid waste produced in Wet-process phosphoric acid (WPPA) technical process, and its main component is CaSO
42H
2o, in May, 2006, State Environmental Protection Administration was with ring letter (2006) No. 176 civilian forms, by qualitative for ardealite be dangerous solid waste, be classified as the controlling object of national noxious waste pollution environment.Therefore the harmless treatment of ardealite and comprehensive utilization become one of focus of Resource Recovery of Industrial Solid Waste research field.
The recycling of ardealite has become the key that phosphate fertilizer industry realizes sustainable development.Therefore, how to fully utilize ardealite, control pollution that ardealite produces, the treatment of wastes with processes of wastes against one another, improve the value of ardealite, create good social benefit and environmental benefit and just seem and be even more important.Ardealite may be used for processing lead waste water in utilization, it is a kind of method of the treatment of wastes with processes of wastes against one another, but the ardealite adsorption capacity of non-modified and specific area on the low side, be directly used for processing lead waste water and can not reach emission request (<1mg/L) to lead in country " integrated wastewater discharge standard " (GB8978-1996).
It is the processing method disclosing a kind of lead waste water in the patent of CN1854094A at publication number.The method utilizes the method process lead waste water of electrodialysis and ion-exchange.Its processing step for described lead waste water is entered electrodialysis plant after precipitation process, at pH value 6 ~ 9, deep or light water ratio 1:2 ~ 5, operating current 2 ~ 6A/cm
2, circular treatment 2 ~ 6 times under waste water flow velocity 100 ~ 300L/h condition, the fresh water after electrodialysis enters ion exchange column with 50 ~ 200I/h flow velocity again, obtains treated water.But there is following shortcoming in the method: (1) needs the sewage treatment facility of supporting response, adds processing cost; (2) waste water after process only reaches reuse standard, does not reach outer row's standard.
Be in the patent of CN1854094A, disclose a kind of processing method utilizing mushroom culture medium waste to remove lead-containing industrial wastewater at publication number.The method utilizes the method process lead waste water of mushroom culture medium waste.Its processing step, for using wood chip, rice bran, gypsum and lime, mixes with water the mushroom culture medium made, and through indoor temperature control product mushroom process in 2 ~ October, mushroom culture medium fully becomes thoroughly decomposed; After it can not produce mushroom, by culture medium high temp fire bacterium and pulverization process, make mushroom culture medium waste biological adsorption agent; Consumption is 1 ~ 2kg/m
3biological adsorption agent join in lead waste water, adjust ph, under the condition of temperature 20 ~ 30 DEG C, utilizes compressed air stirring and adsorbing, filtering adsorbent after 24 ~ 48 hours.But there is following shortcoming in the method: (1), when quantity of sorbent consumption is large, raw material not easily obtains; (2) waste material after process is comparatively difficult in desorb.
Foreign study proves, the ardealite not carrying out modification has certain characterization of adsorption, has good absorption property under appropriate conditions to lead.Ardealite simultaneously after absorption can utilize again as building materials after super-dry process, thus achieves the process of ardealite comprehensive utilization of resources.But there is no the report research utilizing neopelex to combine obtained material modified sorbent treatment lead accumulator (leaded) waste water of ardealite at present both at home and abroad.
Summary of the invention
The object of the present invention is to provide a kind of preparation method processing lead waste water adsorbent, specifically comprise the following steps:
(1) remove impurity, decompress filter after being washed by ardealite, after then temperature being risen to 160 DEG C by the heating rate of rising 5-10 per hour DEG C, insulation 14 ~ 18h, obtains pretreated ardealite sample;
(2) neopelex is added in ethanol by the ratio being 1:3 ~ 1:5 in neopelex and ethanol mass ratio, under 20 ~ 28 DEG C of environment, stirs 0.2 ~ 1.2h, is mixed with organically-modified solution;
(3) in the ratio of 6 ~ 12g/30mL pretreated ardealite sample added in the organically-modified solution obtained in step (2) and be configured as half-dried reaction mass, be placed in flat bottom glass vessel, evenly spread out, leave standstill 20min-60min, then ultrasound reactor is put into, take out sample after reaction 25-35min, cross 120 ~ 180 mesh sieves after grinding, obtain adsorbent.
Process lead waste water adsorbent of the present invention is for the treatment of lead waste water: by adsorbent with dosage for 6 ~ 12g/L, the concentration of Pb In Exhausted Water ion is 40 ~ 60mg/L, treatment temperature is 20 ~ 28 DEG C, pH=7 ~ 8, mix and stir, filter after contact 50 ~ 90min, and measure the content of lead ion in the filtrate after process.
Neopelex of the present invention and ethanol be analyze pure.
Neopelex of the present invention is anion surfactant, forms modified composite material with ardealite, can react, thus realize the removal of heavy metal lead ion with the heavy metal lead ion generation chemical complexing in waste water; Ardealite itself has larger specific area, and by this method of modifying, the ardealite after can making process further has higher adsorption capacity, enables to become a kind of good adsorbent material removing lead ion.
Compared with prior art, the invention has the advantages that:
(1) the present invention utilizes neopelex modified ardealite, increases the adsorption capacity of ardealite, makes it have better adsorption function;
