Description
Technical field
The present invention relates to a kind of lead storage battery waste water deleading equipment, is mainly for lead storage battery industry waste water, is specially a kind of deleading equipment for lead storage battery waste water.
Background technology
Lead storage battery waste water is divided into factory effluent and sanitary sewage, factory effluent is mainly derived from leaded, the acid-bearing wastewater that product produces in production process, technique or the dust removal by ventilation water such as derive from complex acid, coated plate, change into, mainly contains lead powder, melts lead, lead sulfate, sulfuric acid and some other organic additive and machine oil etc. in these waste water; Auxiliary department is as carried out leaded, the acid-bearing wastewater of the generation of analysis of experiments chamber in battery laboratory, battery analyzer room to battery product; Employee work takes rinse water, employee's waste water of having a shower, and each production process is clean and employee washes one's hands waste water etc., pollutent is mainly COD, SS and the pollutent such as plumbous, as having a strong impact on the healthy of operating personnel without improvement, the serious the harm simultaneously environment of periphery being caused.
Lead storage battery waste water deleading method mainly contains chemical precipitation method, oxidation reduction process, ion exchange method, ferrite process etc. at present.Wherein chemical precipitation method is comparatively practical, it is to point in waste water to add chemical agent, makes medicament and heavy metal contaminants generation chemical reaction, forms the solid resultant throw out of indissoluble, then carry out solid-liquid separation, thereby remove a kind for the treatment of process of Pollutants in Wastewater.
Chemical precipitation method comprises hydroxide precipitation method, sulphide precipitation and carbonate precipitation method etc.At present conventional hydroxide precipitation method is removed the heavy metal in lead storage battery waste water, utilize lime to regulate pH value to alkalescence, in primary clarifier, add flocculation agent seizure heavy metal, with inclined-plate clarifying basin restriction heavy metal, rise, with the double-layer filter material hard coal in rapid filter, the water outlet of quartz sand filtration precipitation, water outlet regulates pH value to 6-9.
This method is processed lead storage battery waste water, adopt the operation of feeding lime stone, behaviour's technique is simple, working cost is cheap, but labor strength is high, operation of equipment is backward in technique, the split type main equipment of many employings, direct feeding lime, dosage is large, produce body refuse amount large, sedimentation effect is poor, the settlement request time is long, corresponding settling tank floor space is large, add inclined tube, sedimentation effect is better, but because the body refuse amount producing is large, swash plate easily stops up, equipment repair is difficult in maintenance, it is large that a large amount of body refuses is cleared difficulty, body refuse heavy metal content is higher, form danger useless, be difficult to dispose, adopt and dissolve rear feeding lime breast, because dosage is larger, cause wastewater flow rate to increase, increase load.Hydroxide precipitation method deleading, the optimal ph of lead hydroxide precipitation is 9-9.5, the pH value scope of application is less, be difficult to control, when pH reconciles, fluctuate larger, cause water outlet lead content unstable, therefore, adopt hydroxide precipitation method deleading can not guarantee water outlet lead content stably reaching standard.In addition, lead storage battery waste water is acid waste water, adopting hydroxide precipitation method deleading to need first waste water to be added alkali regulates pH to alkaline condition ability removal heavy metal, it is neutral that water outlet requires pH, so also need to add acid for adjusting pH value to 6-9, this method can consume a large amount of soda acids, causes saltiness in waste water to increase, and can increase the operating load of follow-up waste water recycling process.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of deleading equipment for lead storage battery waste water, simple to operate, processing efficiency is high, floor space is little, gather efficient deleading technology, sedimentation techniques, the integrated lead storage battery waste water deleading of filtering technique equipment, can not stably reaching standard after having solved current lead storage battery industry lead waste water and processing, produce the problem of a large amount of Hazardous wastess.
