Description
Technical field
The invention belongs to technical field of sewage, are related to a kind of coagulative precipitation device.
Background technique
Coagulating sedimentation is treatment process most basic in industrial water and sanitary sewage disposal, by adding into water
Medicament (commonly referred to as coagulant and flocculation aid), enables the particle for being difficult to precipitate in water to be aggregated with one another and form colloid, then with
Impurity in water body, which combines, forms bigger floccule body.Floccule body has powerful adsorption capacity, can not only adsorb suspended matter, moreover it is possible to inhale
Attached part bacterium and dissolved matter.Floccule body is increased and is sunk by absorption, volume.Under the action of coagulant, in waste water
Colloid and fine suspension be condensed into floccule body, be then separated off floccule body.Coagulating sedimentation can both reduce the turbid of raw water
The sense index of the water quality such as degree, coloration, and a variety of hazardous contaminants can be removed.
However, existing coagulative precipitation tank is generally divided into two pond bodies of coagulation and precipitating, settling zone is entered back into after coagulation is abundant
Precipitation and separation is carried out, higher cost takes up a large area.In addition, existing precipitation process of coagulation is mostly intermittently operated, every batch of
Secondary to handle a certain amount of sewage, treatment effeciency is lower.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of coagulative precipitation devices.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of coagulative precipitation device, the device include hybrid reaction unit and the precipitating that is connected with hybrid reaction unit
Separative unit, the hybrid reaction unit are equipped with water inlet, and the precipitation and separation unit includes shell and is arranged in shell
The inner space of shell is divided into sedimentation side and separation side by the partition in internal portion, the partition, and the housing bottom is equipped with and sinks
The mud discharging mouth that drop side is connected, the separation side are equipped with baffle separating mechanism, and the housing side is equipped with and separation side phase
The water outlet of connection.
Further, the mixing that the hybrid reaction unit includes water inlet pipe and is arranged between water inlet pipe and shell
One end of water inlet pipe is arranged in reaction tube, the water inlet.Sewage enters water inlet pipe by water inlet, after through hybrid reaction pipe
Into separation side.
Further, the water inlet pipe is equipped with heater.In view for the treatment of effect of the water temperature to coagulant has very
It is big to influence, and will affect the synthesis speed of floccule body, so sewage is adjusted to suitable temperature in advance by setting heater
Degree, guarantees the efficient progress of subsequent coagulation process.
Further, the first medicament feed opening, second medicament are successively arranged along water (flow) direction on the hybrid reaction pipe
Feed opening.The medicaments such as coagulant, flocculation aid are added by the first medicament feed opening, second medicament feed opening respectively, make itself and dirt
Water mixing and coagulation.
Further, first flow control meter, the second medicament charging are equipped at the first medicament feed opening
Second flow control meter is equipped at mouthful.The charging of the first medicament is adjusted by first flow control meter, second flow control meter respectively
The feed rate of mouth, second medicament feed opening, when sewage flows through the first medicament feed opening, second medicament charging with certain flow
When mouth, corresponding medicament just synchronizes addition with the flowing of sewage, reaches uniform admixture, eliminates subsequent machinery and stirs
Mix mixing step.
Further, one end of the hybrid reaction pipe is equipped with acclivitous diversion pipe, which is located at sedimentation
The inside of side.Sewage in hybrid reaction pipe enters sedimentation side obliquely, generates certain impact to the water on sedimentation side upper layer and stirs
Mix effect.
Further, the bottom of the shell is arc-shaped, and the partition is arc-shaped partition.The sludge edge to settle down
The curved surfaces of shell and the curved surfaces slide downward of partition, after be discharged through mud discharging mouth.
Further, the baffle separating mechanism includes multiple the of separation side being successively alternately laid in along water (flow) direction
The top of one baffle and second baffle, the first baffle is connected with case top, the bottom end of the second baffle and shell
Body bottom is connected, and the bottom end of the first baffle is lower than the top of second baffle.It settles the upper water inside side and passes through partition
Top enters separation side, since the alternating of first baffle and second baffle is laid, changes water (flow) direction constantly quickly, in water flow
The a small amount of floccule body mixed is precipitated to housing bottom after just being intercepted by first baffle and second baffle.
Further, the height of the water outlet is greater than the bottom end height of first baffle.Settle the upper water warp in side
After the further purification of baffle separating mechanism, it is discharged by water outlet.
Further, the bottom of the second baffle and partition offers spoil disposal channel.By first baffle and second
Baffle is precipitated to housing bottom sludge after intercepting passes through the spoil disposal channel of second baffle bottom and the spoil disposal channel of partition bottom
Enter sedimentation side afterwards, and mixed with the sludge of sedimentation side bottom, is discharged together through mud discharging mouth later.
The present invention in practical application, sewage is entered in hybrid reaction unit by water inlet, in hybrid reaction pipe with throwing
The coagulant and flocculation aid hybrid reaction added enters the intracorporal sedimentation side of shell later and settles, and the sludge to precipitate is through arranging
The discharge of mud mouth, upper water enters separation side, and is further separated out sludge under the action of baffle separating mechanism, later by being discharged
Mouth discharge.
Compared with prior art, the invention has the characteristics that：
1) it can continuously be passed through sewage and carry out coagulating kinetics, substantially increase the treatment effeciency of sewage, simplify behaviour
Make, reduces costs；
2) coagulating basin and mechanical stirring device are eliminated, while passing through continuum micromeehanics and synchronizing and adding medicament and ensure that medicament
Uniform with water mixes；
3) baffle separating mechanism can further purify the upper water after precipitating in sedimentation side, ensure that the processing of sewage
Effect, while the sludge for separating side bottom is easy to be discharged.
