Description
Technical Field
The utility model relates to a waste water treatment technical field, in particular to processing system of pickling waste water.
Background
The metal surface treatment industry has an acid pickling process in the production process, and a large amount of waste water is generated after acid pickling, wherein the waste water mainly contains sulfuric acid and phosphoric acid, and the waste water is strong in acidity. If the wastewater is not reasonably treated and is directly discharged, the nearby water body and soil can be seriously deteriorated.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a processing system of pickling waste water, the operation is safe, stable, and easy operation, management are convenient, adopt neutralization + deposit + the technology of filter-pressing, have not only reduced environmental pollution, make waste water resourceization moreover.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a processing system of pickling waste water, includes sedimentation tank 2, neutralization pond 1 and discharge tank 3, its characterized in that: the device comprises a neutralization pond 1 and is characterized in that a water inlet 1-1 is arranged on the neutralization pond 1, a stirring device 1-2 is arranged right above the neutralization pond 1, a PH automatic control system 1-3 is arranged on one side of the stirring device 1-2, a dosing system 1-4 is arranged at one end of the PH automatic control system 1-3, a water outlet is arranged at the bottom of the neutralization pond 1, the water outlet is connected with a sedimentation pond 2 through a lifting pump 1-5, a dosing device 2-1 is arranged on the upper portion of the sedimentation pond 2, an overflow weir 2-2 is arranged on one side of the upper end of the sedimentation pond 2, a discharge pond 3 is arranged on one side of the sedimentation pond 2, and a liquid level meter 3-1 is.
Preferably, the water outlet of the neutralization tank 1 is level with the neutralization tank 1. The beneficial effects are that: this configuration allows all of the waste water in the neutralization tank to be discharged to the settling tank by the lift pump.
Preferably, the bottom of the sedimentation tank 2 is of an inclined wall closing structure. Has the advantages that: the design ensures that the sludge can not be remained in the sedimentation tank, and keeps the fluidity of the wastewater in the sedimentation tank.
Preferably, the top of the discharge tank 3 is higher than the height of the overflow weir 2-2. The beneficial effects are that: the design can effectively prevent supernatant liquid in the discharge tank.
Compared with the prior art, the beneficial effects of the utility model are that: the operation is safe and stable, the operation is simple, the management is convenient, and the process of neutralization, precipitation and filter pressing is adopted, so that the environmental pollution is reduced, and the wastewater is recycled.
