Abstract
The present invention relates to a kind of processing method of lead-containing industrial wastewater, belong to technical field of waste water processing.The present invention uses the nitrogenous weak basic ion exchange resin BS II of macropore, and by resin matrix institute's nitrogen atom and the chelation of lead ion, lead waste water is handled.Macroporous chelate resin of the present invention has stronger adsorption capacity to lead ion, with not only adsorption capacity height, desorption and regeneration easily, the advantages of service life is long.
Description
Technical field
The present invention relates to a kind of processing method of industrial wastewater, it is more particularly related to a kind of leaded Industry Waste
The processing method of water, belongs to technical field of waste water processing.
Background technology
Lead is a kind of toxicity very strong heavy metal, has serious harm to health, and industrial wastewater is removed at present
Technology has chemical precipitation method, biosorption process and electrolysis.Although though the method processing of these processing lead waste water is simple and easy to apply,
But there are certain limitation and shortcoming.And use the macroporous chelate resin to lead with certain chelation to chelate it,
To reach the purpose chromatographic technique removed then because it can effectively handle lead waste water, and regenerated liquid can be reclaimed, no
Produce secondary pollution, and technique it is simple, Automated condtrol can be realized with column operation, removal effect is preferably and by people's
Pay high attention to.Therefore it is expected to turn into a kind of preferably processing lead waste water technology.
The content of the invention
Present invention seek to address that the problem of lead-containing industrial wastewater treatment effect is poor in the prior art contains splicer there is provided one kind
The processing method of industry waste water, the processing method effect is preferable.
In order to realize foregoing invention purpose, its specific technical scheme is as follows：
A kind of processing method of lead-containing industrial wastewater, it is characterised in that：Comprise the following steps that：
A, the nitrogenous 20ml of weak basic ion exchange resin BS- II of macropore are transferred in chromatographic column, efflux is washed till with alcohol in water
In do not produce white opacity；The alcohol in macroreticular resin in net chromatographic column is washed with deionized water；Respectively with 1N HCl, 100ml, 1N
NaOH, 100ml are pre-processed and made the transition to resin；Transition processing is carried out to resin with 1N HCl again, with distilled water or go from
Remaining HCl in son washing straight resin, it is standby；
B, lead waste water is pre-processed, filter, obtain limpid filtered fluid, it is standby；Lead to lead waste water with 20ml/h flow velocity
Cross chromatographic column；Lead waste water is logical finish after, the lead waste water of residual in chromatographic column is washed with deionized water；Use 1NHCl elution chromatographies
The lead of resin adsorption in post；
C, collection efflux；Concentration outflow eluent reclaims lead.
In step, the nitrogenous weak basic ion exchange resin BS- II of macropore is 20ml to the present invention.
In step, the lead waste water is 1200ml to the present invention.
The advantageous effects that the present invention is brought：
This patent uses the nitrogenous weak basic ion exchange resin BS- II of macropore, passes through resin matrix institute's nitrogen atom and lead ion
Chelation, is handled lead waste water.The macroporous chelate resin that this patent is used has stronger energy of adsorption to lead ion
Power, with not only adsorption capacity height, desorption and regeneration easily, the advantages of service life is long.
