Said neutralization reaction pond is used for the Cr with waste water 3+And Mn 2+With generate precipitation of hydroxide after the milk of lime neutralization reaction;
Said flocculation tank is used for waste water and wherein PAC and PAM are carried out coagulating, makes suspended matter and colloid quilt wadding in the water adsorb through coagulation;
Said tube settler is used for through gravity fractionation, makes throw out and settling of floccus in the water;
Said mud storage pool has the gravity concentrating function, the mud of be used to collect autoflocculation reaction tank and tube settler, and the supernatant in the mud storage pool is discharged in the waste water scratch pool through pipeline;
Said plate-and-frame filter press receives the mud from mud storage pool, and mud is discharged, and filtrating is discharged in the waste water scratch pool through pipeline.
In technique scheme, the rear end of said tube settler is connected with clean water basin, is used to reclaim the waste water of handling the back qualified discharge through tube settler.
In technique scheme, all be provided with the pH value in said reduction pond and the neutralization reaction pond and measure indicating meter.
Can find out that from the constitutional features of above-mentioned the utility model its advantage is: through this apparatus processes waste water, in treating processes, adopt lime, ferrous sulfate to add the composite treatment process of flocculation sediment, can effectively remove Cr 6+Deng pollutent, have reduced investment, take up an area of less, advanced technology is reliable, be convenient to advantage such as management, especially, and can reuse through the water outlet after this apparatus processes, maximization realizes comprehensive utilization and the minimizing of the resource harm to environment.
Description of drawings
The utility model will and combine the mode of instance to explain through the accompanying drawing comparison:
Fig. 1 is the utility model structural principle synoptic diagram;
Fig. 2 is the principle schematic that the utility model carries out wastewater treatment;
Wherein Reference numeral 1 is that waste water scratch pool 2 is that reduction pond 3 is neutralization reaction ponds
The 4th, flocculation tank 5 is that tube settler 6 is mud storage pools
The 7th, plate-and-frame filter press 8 is clean water basin.
Embodiment
Through embodiment the utility model is done further explanation below in conjunction with accompanying drawing:
Like Fig. 1 and shown in Figure 2, a kind of electrolytic manganese Industrial Wastewater Treatment and the reclamation set of the utility model, its wastewater treatment process is: when waste water processing station normally moves; Electrolytic manganese waste water to waste water scratch pool from the production plant discharging; Pump into the reduction pond from the waste water scratch pool through waste water again, add sulfuric acid to the reduction pond, regulating the pH value is 2~3; Continuously stirring is with 10% the FeSO for preparing 4Solution joins the reduction pond with Cr 6+Be reduced into Cr 3+Gravity flows into the neutralization by lime pond then, and the concentration that adding prepares in the neutralization reaction pond is 10% Ca (OH) 2Solution, regulating the pH value is 8~9, generates chromium hydroxide and manganous hydroxide deposition, removes Cr 6+And Mn 2+The waste water in neutralization reaction pond flows by gravitational force into flocculation tank; On this pipeline, add PAC successively and PAM carries out coagulating; Make suspended matter, colloid quilt wadding in the water adsorb through coagulation; Water outlet gravity flows into tube settler, through precipitating action the macrobead settling of floccus is got off.The water outlet of tube settler is through the clean water basin reuse.The mud of flocculation tank and tube settler flows by gravitational force into mud storage pool and stores, and to plate-and-frame filter press, filtrating enters the waste water scratch pool to the mud in the mud storage pool through lift pump, and dewatered sludge is transported to specified place.
