Abstract
The utility model discloses a system for treating acid washing heavy metal waste water of steel wire ropes, which comprises an anaerobic bioreactor which reduces sulfate as waste water which contains sulfide or hydrogen sulfide, wherein the anaerobic bioreactor is connected with a waste water reaction tank; and the waste water reaction tank is connected with a waste water sedimentation tank. The system for treating acid washing heavy metal waste water of steel wire ropes disclosed by the utility model is reasonable in structure, treats acidic heavy metal waste water of the steel wire ropes by microorganisms, thereby reducing treatment cost of waste water; the system can realize sedimentation of heavy metal ions, such as, Pb ions and Zn ions, in waste water without regulating pH value to realize alkaline condition; after treatment by the system, the removal rate of the heavy metal ions is greater than 99%, the concentration of the Pb ions in discharged water is less than 0.2 mg/L and the concentration of the Zn ions is less than 1.0 mg/L; in addition, the system can realize discharge up to the standard steadily without regulating the pH value, thereby reducing the use amount of alkali liquor of physico-chemical methods; and the system reduces generation of sludge and further improves the dewatering performance of the sludge.
Description
Technical field
The utility model relates to a kind of wireline pickling heavy metal containing wastewater treatment system.
Background technology
The waste water that produces in the Wire Rope Production, general direct discharging of prior art or process complex processing, effect is undesirable.
Summary of the invention
The purpose of the utility model is the wireline pickling heavy metal containing wastewater treatment system that provides a kind of treatment effect good.
The technical solution of the utility model is:
A kind of wireline pickling heavy metal containing wastewater treatment system, it is characterized in that: comprise the anaerobic biological reactor that sulfate reduction is formed sulfur compound or hydrogen sulfide waste water, anaerobic biological reactor is connected with the waste water reaction pond, and the waste water reaction pond is connected with effluent settling chamber.
The waste water reaction pond is connected with water collecting basin.
The utility model is rational in infrastructure, uses microbiological treatment wireline acid heavy metal waste water, reduces cost for wastewater treatment; Need not to regulate pH to alkaline condition, can realize the deposition of Pb in the waste water, Zn heavy metal ion, clearance is greater than 99%; Water outlet Pb ionic concn less than 1.0mg/L, and need not to transfer pH less than 0.2mg/L, Zn ionic concn again, but the stably reaching standard discharging; Reduce the usage quantity of physico-chemical process alkali lye, reduced the mud generation simultaneously, and improved the dewatering of mud.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
A kind of wireline pickling heavy metal containing wastewater treatment system comprises the anaerobic biological reactor 1 that sulfate reduction is formed sulfur compound or hydrogen sulfide waste water, and anaerobic biological reactor is connected with waste water reaction pond 2, and the waste water reaction pond is connected with effluent settling chamber 3.The waste water reaction pond is connected with water collecting basin 4.
The principle of work of the utility model is:
Adopt the bacterium vulcanization process, sulphate reducing forms sulfur compound or hydrogen sulfide waste water in anaerobic biological reactor, and with wireline waste water (pH<1) hybrid reaction in the waste water reaction pond makes when improving pH, makes the heavy metal partly precipitated, adds alkali and stirs, and regulating pH is 5 ~ 7, and heavy metal Pb, Zn ionic clearance can reach more than 95% in the waste water; Further utilize N
2The stripping mode gets into the waste water reaction pond with the biogas stripping that produces in the anaerobic biological reactor, and heavy metal precipitation is strengthened in further reaction, at this moment wastewater effluent Pb ionic concn<0.2mg/>L, the Zn ionic concn<1.0mgL, equal allow compliance with emission standards, mikrobe also has certain removal effect to ammonia nitrogen in the waste water simultaneously, satisfies the requirement less than 15mg/L.
