Abstract
The utility model discloses a sulfate wastewater reclamation device which is characterized by comprising a first-level nanofiltration system and a second-level nanofiltration system. For the sulfate wastewater reclamation device, a two-level nanofiltration treatment process is adopted to separate Zn, Cd, Fe, Cu and other heavy metal ions in sulfate wastewater from H2SO4 and As, and permeation liquid mainly contains sulfate and a small amount of heavy metal and can be directly recycled, thus greatly saving cost and sulfate emission amount.
Description
Technical field
The utility model relates to a kind of waste disposal plant, particularly relates to a kind of sulfuric acid wastewater containing reclamation set.
Background technology
Metallurgy industry dust treatment workshop spent acid reuse technology mainly is that the acid behind the heavy arsenic is back to use the leading portion operation again, helps saving cost like this, reduces wastewater discharge.But when the continuous cyclically utilizing of spent acid, the heavy metal in the waste water also will constantly be accumulated rising, thereby the operational indicator control of the whole technological process of influence and the closed cycle operation of producing liquid do not reach the environment protection emission requirement.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to design a kind of sulfuric acid wastewater containing reclamation set, reaches the purpose of the reuse of sulfuric acid wastewater containing.
For achieving the above object, the technical scheme that the utility model proposed is: a kind of sulfuric acid wastewater containing reclamation set is characterized in that comprising:
1) one-level nanofiltration system: comprise that the head tank, one-level dehvery pump, first security personnel's strainer, one-level high-pressure pump, the one-level nanofiltration membrane component that link to each other successively by first feed pipe link to each other, the dialyzate outlet of described one-level nanofiltration membrane component links to each other with middle batch can by the first dialysis pipeline, concentrated solution outlet is connected with a reflux line and a reuse pipeline, be separately installed with first valve, second valve on reflux line and the reuse pipeline, the reuse pipeline is connected with the reuse jar;
2) secondary nanofiltration system: comprise by advancing secondary dehvery pump, second security personnel's strainer, secondary high-pressure pump, the secondary nanofiltration membrane component that second pipe material links to each other successively; Described secondary dehvery pump links to each other with middle batch can, and described secondary nanofiltration membrane component concentrated solution outlet links to each other with head tank by concentrating pipeline, and the dialyzate outlet links to each other with dialysate tank by the second dialysis pipeline.
Further, an interchanger is installed also on the described reflux line, feed liquid is lowered the temperature or heat up.
Further, the nanofiltration membrane of being installed in described one-level nanofiltration membrane component and the secondary nanofiltration membrane component is acidproof nanofiltration membrane.
Sulfuric acid wastewater containing reclamation set described in the utility model adopts the secondary nanofiltration to handle industry, with heavy metal ion and H such as the Zn in the sulfuric acid wastewater containing, Cd, Fe, Cu
2SO
4, As separates, and sees through main sulfur acid and a spot of heavy metal in the liquid, cost and sulfuric acid quantity discharged have been saved in directly recycle greatly.
