First point, the coagulating agent input: the fluid in the pipeline is a constant state current downflow comparatively speaking, lacks a fluid stream sudden turn of events, does not reach the short mix purpose.
Second point, adsorption bridging becomes flocs unit: mixing water flows into coagulation reaction tank, need there be certain molten amassing to slow down flow velocity, just give the certain time of arrheaing polyreaction, because reaction tank is big, flow velocity is inhomogeneous in the tank body, and fluid has the dead angle and produces the flocs unit precipitation, the short circuit that has and flow out reaction tank fast, the coacervation effect is undesirable.
Have in order to reduce input cost or the place is limited, just reduce the reaction tank volume,, just increase stirrer and improve coacervation speed owing to reduced the time of arrheaing, but impeller influences polymerization process easily to the montage of water body, and polyreaction is not improved and just flowed into next procedure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, providing a kind of makes the pollution substance in the water obtain abundant reactive polymeric, guaranteed good coagulating treatment effect, increase the coagulating agent input amount in order to avoid coagulation effect is bad, produce the multilevel pipeline-mixed coacervation device of secondary pollution on the contrary.

Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this multilevel pipeline-mixed coacervation device, it comprises the coacervation reaction tubes 1 that some levels are connected in series, and each grade coacervation reaction tubes 1 is snakelike, and is identical with the caliber of one-level coacervation reaction tubes 1, on the working direction of treatment sewage, it is big that the caliber of coacervation reaction tubes 1 becomes step by step.
On the working direction of treatment sewage, next stage coacervation reaction tubes 1 is arranged on the top position of coacervation reaction tubes 1 at the corresponding levels.Have 3 ~ 5 grades of coacervation reaction tubess 1 that are connected in series.On first step coacervation reaction tubes 1, be provided with coagulating agent chemical feed pipe 2, in the coacervation reaction tubes 1 of coagulating agent chemical feed pipe 2 rear ends, be provided with mixed organization 3.On second stage coacervation reaction tubes 1, be provided with coagulant aids chemical feed pipe 4, in the coacervation reaction tubes 1 of coagulating agent chemical feed pipe 2 rear ends, be provided with mixed organization 3.
During work, by of the import of water pump lifting raw waste water to the multilevel pipeline-mixed coacervation device, add coagulating agent by coagulating agent chemical feed pipe 2 again, mixed solution flows through mixed organization 3(can adopt pipeline type blade mixing tube) interior blade, also can add coagulant aidss in the time of then by first step coacervation reaction tubes 1, second stage coacervation reaction tubes 1 by coagulant aids chemical feed pipe 4, change third stage coacervation reaction tubes 1 again over to, go out 8. to enter next procedure by coagulation water.More than every grade of stackable series connection assembling.
Principle of work of the present utility model is:
When mixed solution flow through blade in the mixed organization 3, the frequent sudden turn of events of fluid track promptly was uniformly distributed in the water medicament, then the coacervation reaction tubes 1 by plural serial stage.The mixed solution fluid is a constant state current downflow comparatively speaking in coacervation reaction tubes 1 pipeline, at the turning is rapidly varied flow, play the effect of slow stirring, first group to the 3rd group caliber enlarges step by step simultaneously, flow section also increases step by step, fluid velocity progressively slows down, and plays the buffering over-effect for entering subordinate's operation.
Above principle has conformed to the basic procedure of Coagulation Method: coagulating agent and sewage short mix, slowly stir then, and the polyreaction adsorption bridging becomes flocs unit.Because the formation of flocs unit is to have trickle loosely to progressively thick closely knit earlier, fluid needs one and stablely stops process slowly, is specially:
