Background technology
Lead storage battery, produce plumbic acid waste water in process of production, as without improvement, had a strong impact on the healthy of operating personnel, and the serious harm simultaneously peripheral environment caused.In manufacturing plumbous lead storage battery process, technique or the dust removal by ventilation waters such as the waste water of discharging is mainly derived from complex acid, coated plate, change into, the high-salt wastewaters that poaching wastewater, the lead storage battery that changes into pole plate dresses up that rear Cleaning Wastewater, workshop produce waste water in rinsing containing lead fume waste water, lead dust wastewater treatment and mill floor, concentrate bath wastewater, laundry lead waste water, pure water preparation produce etc., mainly contain lead powder, melt lead, lead sulfate, sulfuric acid and some other organic additive and machine oil etc. in these waste water.Lead wherein is first kinds of pollution matter, as very large in do not dealt carefully with harm.
The method of processing at present lead waste water has: chemical precipitation method, ion exchange method and electroosmose process etc.Chemical precipitation method is current most widely used lead waste water treatment technology.Existing treatment process distributed operation process complexity, energy consumption is high.
Summary of the invention
The treatment process of the plumbic acid waste water that the object of the present invention is to provide a kind of lead storage battery production process to produce.
Purpose of the present invention can be achieved through the following technical solutions:
The treatment process of the plumbic acid waste water that a kind of lead storage battery production process produces, is characterized in that, comprises the following steps:
(1) waste water is introduced in oil trap the suspended substance machine oil class of removing comparatively large vol in waste water, after enter water collecting basin, mix;
(2) waste water of step (1) is promoted to pH regulator tank 1 through lift pump, adds alkali lye and stir, be adjusted to pH to 5-6, the 1 water outlet gravity flow of pH regulator tank enters pH regulator tank 2, add alkali lye and stir, regulating pH to 9-9.5, lead ion and hydroxide ion generate the lead hydroxide precipitation;
(3) waste water of step (2) and lead hydroxide precipitation enter the flocculation reaction tank, add flocculation agent, catch heavy metal and form colloid;
(4) waste water of step (3), through tube settler, carries out the mud-water separation clarification, and supernatant liquor separates with mud, removes part lead hydroxide precipitation and COD, SS;
(5) in step (4) in tube settler supernatant liquor through overflow weir from flowing to quartz filter, remove suspended substance and total plumbous, after flow to activated carbon filter layer, further remove suspended substance and total plumbous;
(6) filter water outlet in step (5) and enter pH readjustment tank, adding concentration is 10% dilute hydrochloric acid, regulates pH to neutral, enters the clean water basin cyclically utilizing.
The mud produced in described step (4) enters sludge sump, with pneumatic diaphragm pump suction plate-and-frame filter press, carries out the compacting mummification, and the mud after mummification is processed as solid waste, also can be melted down smelting, and the supernatant liquor leached returns to water collecting basin and again processes.
In described step (2), alkali lye is sodium hydroxide, and the mass concentration of described sodium hydroxide is 30%.
In described step (3), flocculation agent is PAC and PAM.
In described step (3), the dosage of flocculation agent is 2-4mg/L.
Beneficial effect of the present invention: the treatment process of the plumbic acid waste water that the high lead storage battery production process of the present invention produces, for plumbic acid waste water, employing is in conjunction with the precipitator method and absorption method technique, neutralization, flocculation sediment, filtration one step facture, the technique carrier is changed to suite of equipment by structures, and the advanced floor space for the treatment of facility is little, and mud is used less with easy to operate, this combination process has following advantage:
The processing of the plumbic acid waste water that 1, the lead storage battery production process produces is highly stable, has prevented the generation of Lead contamination accident.
2, the reclamation rate after wastewater treatment can reach 100%, effluent quality reach country's " integrated wastewater discharge standard " (GB8978-1996) first discharge standard and " urban sewage reutilization industry water standard " (GB/T19923-2005) after fully recovering in industry as cooling water, substantially realize the target of lead storage battery production process wastewater zero discharge.
3, tail water reuse, can also reduce a large amount of fresh water consumptions, economizes on resources and cost simultaneously.
4, affected by the pH value little; Do not use harmful chemical reagent; Sludge quantity is few; Non-secondary pollution.
But 5, discharge water reuse; In bacterium mud, the recyclable and bacterium mud of metal can be used as fertilizer.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
The treatment process of the plumbic acid waste water that a kind of lead storage battery production process produces comprises the following steps:
Waste water is introduced into suspended substance and the oils that oil trap is removed comparatively large vol in waste water, enters water collecting basin, regulating water quality, the water yield, and waste water is promoted to pH regulator tank 1 through lift pump, and the NaOH solution that to add mass concentration be 30% also stirs between coarse regulation pH to 5-6; The 1 water outlet gravity flow of PH regulating tank enters pH regulator tank 2, the NaOH solution that to add mass concentration be 30%, and stir and further regulate between pH to 9-9.5, lead ion and hydroxide ion generate the lead hydroxide precipitation; After enter the flocculation reaction tank, by adding flocculation agent PAC, PAM, the dosage of flocculation agent is 3mg/L, makes lead hydroxide produce flocculation reaction, forms large alumen ustum; Alumen ustum carries out the mud-water separation clarification in tube settler, and supernatant liquor separates with mud, removes most lead hydroxide precipitations and part COD, SS; The tube settler supernatant liquor from flowing to quartz filter, is removed suspended substance and total plumbous by quartz filter through overflow weir; After flow to again activated carbon filter layer, further remove suspended substance and total plumbous; Filtering water outlet and enter pH readjustment tank, is 10% dilute hydrochloric acid by concentration, regulates pH to neutral, enters clean water basin, all for reuse.
At first the mud that system produces enter sludge sump and collected, and then with pneumatic diaphragm pump suction plate-and-frame filter press, carries out the compacting mummification, and the mud after mummification is processed as solid waste, also can be melted down smelting, and the supernatant liquor leached returns to water collecting basin and again processes.
