Abstract

The utility model discloses an iron-containing acid wastewater treatment device. The iron-containing acid wastewater treatment device comprises a reaction tank and a sedimentation tank, wherein an iron-containing acid wastewater feed opening and a lime milk feed opening are respectively formed at the upper end of the reaction tank, a stirring paddle is rotatably arranged in the reaction tank, an aerator pipe is laid at the bottom inside the reaction tank, a discharge opening is formed in the bottom of the reaction tank, and a pipeline is led out from the discharge opening, then is connected to a discharge pump and finally goes to the sedimentation tank. The iron-containing acid wastewater treatment device is simple in structure; and iron-containing acid wastewater and lime milk respectively enter the reaction tank from the corresponding feed openings, the lime milk is used for adjusting the iron-containing acid wastewater in the reaction tank to neutral under the condition that the stirring paddle works; then, an aerator pipe valve is opened; after aeration is ended, the discharge pump is used for pumping slurry to the sedimentation tank for naturally settling the slurry, supernatant liquid is neutral water without iron and can be directly discharged, and bottom mud is treated by adopting a conventional method. The iron-containing acid wastewater treatment device is simple, low in manufacturing cost, strong in operability and capable of greatly reducing labor intensity and improving production efficiency.

Description

The treatment unit of Fe-laden acid wastewater
Technical field
The utility model relates to wastewater treatment equipment field, specifically a kind for the treatment of unit of Fe-laden acid wastewater.
Background technology
In oxygenated pigment production process, the especially production of iron oxide yellow, reaction can produce a large amount of iron content (ferrous iron) acid waste water while finishing, and because the repeating utilization factor of waste water is low, a large amount of waste water must could discharge through processing.In the traditional treatment unit of ferric oxide acid waste water, include neutralising arrangement, aerating apparatus, settler etc., plant area area is large and disperse, and causes whole treatment unit to be prone to fault, has reduced production efficiency, has strengthened operator's labour intensity.
Utility model content
The purpose of this utility model is to provide the treatment unit of a kind of simple in structure, failure rate is low, Fe-laden acid wastewater that treatment effect is good.
The technical solution of the utility model is as follows:
A kind for the treatment of unit of Fe-laden acid wastewater, include retort and settling tank, it is characterized in that: the upper end of described retort is respectively equipped with Fe-laden acid wastewater opening for feed and milk of lime opening for feed, in retort, be rotatablely equipped with stirring rake, bottom in retort is equipped with aeration tube, the bottom of retort is provided with discharge port, leads to described settling tank from described discharge port introduction pipe and connecting discharging pump.
The treatment unit of described Fe-laden acid wastewater, is characterized in that: the bottom of described retort and settling tank is pyramidal structure.
The treatment unit of described Fe-laden acid wastewater, is characterized in that: the top of described retort is provided with the motor being in transmission connection with stirring rake.
The treatment unit of described Fe-laden acid wastewater, is characterized in that: the bottom of described settling tank is provided with discharge outlet.
The treatment unit of described Fe-laden acid wastewater, is characterized in that: the blade of described stirring rake has two layers.
The beneficial effects of the utility model:
The utility model is simple in structure, Fe-laden acid wastewater and milk of lime enter retort from corresponding opening for feed respectively, in the situation that opening stirring rake, by milk of lime, the Fe-laden acid wastewater in retort is adjusted to neutrality, open afterwards aeration tube valve, after aeration finishes, through discharging pump by shurry pump to settling tank natural subsidence, supernatant liquid is iron content neutral water not, can directly discharge, bed mud is according to conventional process, make the simple of Fe-laden acid wastewater treatment unit change, laid down cost is low, workable, greatly reduce labour intensity, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
