Description
Technical field
The present invention relates to a kind of preparation method and application processing 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 be electroplate, smelt, cast, pesticide, mining, dyestuff, oil, battery, machinery, leaded particulate matter sedimentation in water body in the industrial wastewater of the industry discharge such as printing and air.Battery industry is the main source of lead waste water, it was reported that the loss that often 1 battery of production results in lead is 4.54 ~ 6810mg, next to 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, i.e. 1mg/L at workshop floss hole.Make a general survey of the treatment technology of lead waste water the most at present, apply technique more, relatively mature and reliable mainly to have: chemical precipitation method, ion exchange, electrolysis, absorption method, bioanalysis, membrane separation process etc..But these methods generally exist, and treatment effect is bad, spend the shortcomings such as high.Therefore, finding the way of a kind of fine solution lead contamination, for the maintenance of good ecological environment, the urban ecological environment that especially industry is flourishing is critically important.
Ardealite is the solid waste produced in Wet-process phosphoric acid (WPPA) technical process, and its main component is CaSO4•2H2O, in May, 2006, State Environmental Protection Administration was with (2006) No. 176 civilian forms of ring letter, by qualitative for ardealite be dangerous solid waste, be classified as the controlling object of country's noxious waste pollution environment.Therefore one of the harmless treatment of ardealite and the comprehensive utilization focus becoming Resource Recovery of Industrial Solid Waste research field.
The recycling of ardealite has become phosphate fertilizer industry and has realized the key of sustainable development.Therefore, how to comprehensively utilize ardealite, control pollution, the treatment of wastes with processes of wastes against one another that ardealite produces, improve the value of ardealite, create good social benefit and environmental benefit just seems and is even more important.Ardealite may be used for processing lead waste water on utilizing, it it is a kind of method for the treatment of of wastes with processes of wastes against one another, but the ardealite adsorption capacity of non-modified is on the low side with specific surface area, it is used directly to process lead waste water and can not reach in country " integrated wastewater discharge standard " (GB8978-1996) the emission request of lead (< 1mg/L).
The processing method of a kind of lead waste water is disclosed in the patent of Publication No. CN1854094A.The method utilizes electrodialysis to process lead waste water with the method for ion exchange.Its processing step is that described lead waste water enters after precipitation process electrodialysis plant, at pH value 6 ~ 9, deep or light water ratio 1:2 ~ 5, operating current 2 ~ 6A/cm2, circular treatment 2 ~ 6 times under the conditions of waste water flow velocity 100 ~ 300L/h, the fresh water after electrodialysis enters ion exchange column with 50 ~ 200I/h flow velocity again, obtains the water processed.But the method has the disadvantage in that (1) needs the sewage treatment facility of supporting response, adds processing cost；(2) waste water after processing only reaches reuse standard, is not reaching to outer row's standard.
A kind of processing method utilizing mushroom culture medium waste to remove lead-containing industrial wastewater is disclosed in the patent of Publication No. CN1854094A.The method utilizes the method for mushroom culture medium waste to process lead waste water.Its processing step is for wood flour, Testa oryzae, Gypsum Fibrosum and Calx, mixing, 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 pulverization process, make mushroom culture medium waste biological adsorption agent;Consumption is 1 ~ 2kg/m3Biological adsorption agent join in lead waste water, regulate pH value, under conditions of temperature 20 ~ 30 DEG C, utilize compressed air stirring and adsorbing, after 24 ~ 48 hours, filter adsorbent.But the method have the disadvantage in that (1) when quantity of sorbent consumption is big, raw material be difficult to obtain；(2) waste material after processing is the most difficult in terms of desorbing.
Foreign study proves, the ardealite not being modified has certain characterization of adsorption, has good absorption property under appropriate conditions to lead.Ardealite after absorption can utilize as building materials after dried again simultaneously, it is achieved thereby that the process of ardealite comprehensive utilization of resources.But there is no the report research of material modified sorbent treatment lead battery (leaded) waste water utilizing dodecylbenzene sodium sulfonate associating ardealite to prepare at present both at home and abroad.
Summary of the invention
It is an object of the invention to provide a kind of preparation method processing lead waste water adsorbent, specifically include following steps:
