Abstract
The invention which discloses a desulfurized lead-containing wastewater recycling processing method relates to the technical field of lead ore smelting. The method is characterized in that the method comprises the following steps: adding a 20-50% sodium sulfide solution with the weight required by a theoretical reaction at normal temperature according to the content of heavy metals in the wastewater, stirring to fully react, taking a quantitative amount of the obtained solution, adding the sodium sulfide solution drop by drop to inspect until no deposition appears, that is, the reaction is completed, filtering out filter residues, slowly adding the filtered solution to a theoretic amount of barium hydroxide, reacting for 20-60min under stirring, and filtering to obtain barium sulfate which can be applied to the storage battery manufacturing operation and a sodium hydroxide solution which returns to a desulfurization system. According to the method of the invention, the heavy metals of lead, copper, cadmium and the like can be removed from the desulfurized lead-containing wastewater, and the wastewater is regenerated into the sodium hydroxide solution which returns to the desulphurization operation with above barium salt, so a problem of secondary pollution of traditional technologies is fundamentally and scientifically avoided, no pollutants are discharged, and energy saving and environmental protection are realized.
Description
Technical field
The present invention relates to the lead ore technical field of smelting, be specifically related to a kind of desulfurization lead waste water recycle treatment process.
Background technology
At present Production of Secondary Lead enterprise adopts lime treatment, desulfurization wastewater, and the gypsum that is produced contains heavy metals such as lead, belonging to that danger is useless will to cause secondary pollution.Therefore, the present invention is for the secondary lead industrial park, and not only economic benefit is obvious, and can embody the huge social ecological benefits.Such as; National recycling economy manufacturing district (criticized again in April, 2011 and be national city mineral products demonstration base) is sought in the field, Jieshou City; Year is reclaimed 600,000 tons of waste batteries; Annual output pole plate 3,000 ten thousand covers, more than 300 ton of civil water (not comprising domestic water) adopts the barium salt processing to make its recycle if will produce the lead waste water of regeneration lead pig, pole plate, the generation of storage battery process; But 300 tons of water saving every day, and can scientifically evade traditional technology (to lead waste water through converting a certain amount of lime treatment) from the source and produced pollution problems for the second time.
Summary of the invention
Technical problem to be solved by this invention is to the weak point that exists in the prior art a kind of desulfurization lead waste water recycle treatment process to be provided.
Technical problem to be solved by this invention adopts following technical scheme to realize,
A kind of desulfurization lead waste water recycle treatment process, it is characterized in that: described treatment process is at first to press the heavy metal content in the waste water; The 20%--50% sodium sulfide solution that contains that adds the required weight of theoretical reaction at normal temperatures purifies, and stirring is got volumetric soiutions after treating fully reaction; The inspection of dropping sodium sulfide solution does not react completely until having deposition, being; Again the sodium sulfide solution that reacts completely is carried out filtration treatment, the filter residue that filters out is sent into smelting procedure and is smelted, and the sodium sulfide solution after will filtering then slowly adds the hydrated barta of theoretical amount; Carry out the sodium hydroxide regenerative response, stirring reaction 20-60 minute, filter again; Obtain permanent white and sodium hydroxide solution, permanent white can be used for store battery manufacturing process, and sodium hydroxide solution returns desulphurization system from new utilization.
The invention has the beneficial effects as follows: the present invention can slough heavy metals such as containing lead, copper, cadmium in the desulfurization wastewater; And be regenerated as sodium hydroxide solution with barium salt; Return desulfurization process; Scientifically evade traditional technology (to lead waste water through converting a certain amount of lime treatment) from the source and produced pollution problems for the second time, had no pollutant emission, energy-conserving and environment-protective.

Embodiment
For technique means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with specific embodiment, further set forth the present invention.
As shown in Figure 1, a kind of desulfurization lead waste water recycle treatment process, described treatment process do,
At first press the heavy metal content in the waste water, the 20%--50% sodium sulfide solution that contains that adds the required weight of theoretical reaction at normal temperatures purifies, after fully reaction is treated in stirring; Get volumetric soiutions, drip the sodium sulfide solution inspection, until there not being deposition; Be and react completely, again the sodium sulfide solution that reacts completely is carried out filtration treatment, the filter residue that filters out is sent into smelting procedure and is smelted; Sodium sulfide solution after will filtering then slowly adds the hydrated barta of theoretical amount, carries out the sodium hydroxide regenerative response, stirring reaction 20-60 minute; Filter again; Obtain permanent white and sodium hydroxide solution, permanent white can be used for store battery manufacturing process, and sodium hydroxide solution returns desulphurization system from new utilization.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification sheets just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
