The U-shaped micro swirl flocculation sedimentation tank has wide application range, the treatment effect of efficiently removing suspended matters can be achieved rapidly, the removing efficiency is far higher than that of the ordinary flocculation sedimentation tank, the occupation area is small, resistance to impact load is high, and the operation is simple and easy to control.
Description
One, technical field
The utility model relates to the sewage of water treatment field, middle water treatment device, is that a kind of efficient precipitator method are removed suspended substance and part metals ionic water treatment device specifically.
Two, background technology
Coagulating sedimentation is the core technology of conventional water treatment, and coagulation process is divided into waterpower and stirs and mechanical stirring two big classes, because the mechanical stirring energy is difficult to uniformly distributing, energy utilization efficiency is low, the mechanical means maintenance workload is big in addition, and therefore, it is in the majority that China uses waterpower to stir coagulation process.The waterpower whipped form is varied, and partition plate reaction tank, cyclone reaction pond, water clarifier, plusator, flap reaction tank, waved plate reaction tank etc. are arranged, and in recent years, the grid reaction pond is popular.The theoretical analysis and a large amount of engineering practice, people recognize that the coagulation efficiency technology more in the past in grid reaction pond is significantly improved.
At coagulating district layout grid, its objective is that micro swirl helps the diffusion of particulate in the water, makes full use of fluid energy in order to form small vortex flow, increase the collision probability of taking off steady micelle, improve aggregation efficiency.
Depositing technology mainly adopts settling tank, and traditional horizontal sedimentation tank advantage is a simple structure, and is safe and reliable; Shortcoming is that floor space is big, and processing efficiency is low, wants to reduce the length that the turbidity of filtering preceding water will strengthen settling tank significantly.The significant progress that the appearance of shallow pool theory has precipitation technology.After the seventies, China various places water factory has generally used tube settler, and sedimentation effect has obtained increasing substantially, and than common settling tank, about water production rate doubles, and the precipitated outlet water turbidity is lower also more stable.
Three, utility model content
The purpose of this utility model is: propose a kind of U type micro swirl flocculation sedimentation tank, solve the present situation that efficient is not high, capacity of resisting impact load is not strong that the available coagulation settling apparatus is handled, to improve the removal efficient and the capacity of resisting impact load of suspended substance, be particularly useful for the bigger engineering of water treatment of higher suspension content and change of water quality, save investment and floor space, improved the processing power and the stability of system.
Technical solutions of the utility model are: U type micro swirl flocculation sedimentation tank, comprise inhalant region, micro swirl reaction zone, tube settling district, and the micro swirl reaction zone is provided with the grid reaction device, and inhalant region, micro swirl reaction zone and tube settling district are arranged in same pond body; Wherein the micro swirl reaction zone is arranged on flocculation sedimentation tank central authorities, tube settling district annular, and annular tube settling district is arranged on micro swirl reaction zone outer ring.The structure formation of described micro swirl reaction zone is different from traditional flocculation tank, and the cross section forms U type micro swirl flocculation sedimentation tank.
Further, the inhalant region water inlet pipe is located at the bottom water inlet, and shore pipe is located at tube settling district sidewall, from tube settling district sidewall spoil disposal; The utility model comprises that also the dosing of medicine system enters the micro swirl reaction zone.The tube settling district also is provided with the inclined tube filler in addition.
Further, micro swirl reaction zone and tube settling district adopt the concentric tube structure.
Sewage enters annular flocculation reactor by inhalant region, after the dosing flocculation reaction, can increase the particle collision number of times significantly by flocculation reactor, improves flocculating effect effectively.Owing to cross the inertia effect of net current, made the maelstrom of net current become little vortex, little vortex becomes littler vortex, thereby makes that alumen ustum becomes more closely knit after the flocculation reactor.After flocculation reaction, the SS particle forms big stable alumen ustum and enters the tube settling district, and the suspended substance in the water (SS) etc. are deposited on the inclined tube under the effect of inclined tube, slowly slip into sludge discharging area, through the suction dredger sucking-off, drain into sludge treating system.Described catchment area is arranged at the top, settling region of U type micro swirl flocculation sedimentation tank, is used for collecting through the reacted clear water of coagulating sedimentation, adopts stainless steel annular water leg, and it is even to receive water.
The beneficial effects of the utility model: (1) micro swirl coagulation process has been created high efficiency cohesion and flocculation hydraulics, its coagulation efficiency is better than traditional coagulation process greatly, also be better than the grid coagulation process, reaction times can shorten to 5 ~ 8 minutes, this just means with traditional technology compares, water production rate can double, and takes up an area of to lack reduced investment; (2) adding under the situation of identical coagulating agent, the flco quality that the micro swirl coagulation process is produced is better than traditional technology significantly, thereby has good settling property.Under the situation of settling region constancy of volume, water production rate doubles, and delivery turbidity is stabilized in below 3 degree; (3) hydraulics of coagulation is not the macroscopic velocity that mainly depends on current, but relies on the formation of eddy current, and the variable quantity that the formation condition of eddy current mainly depends on flow velocity is the percentage of open area of flocculation reactor.In addition, micro swirl coagulation district has accumulated a large amount of active flcos, and they have shock absorption to the variation of the water yield, water quality, cut off the water or pond water emptying during, these flcos can not deposit to harden and can not discharge outside the pond yet, and this makes that the micro swirl settling tank can discontinuous operation.The utility model U type micro swirl flocculation sedimentation tank is integrated in one the micro swirl reaction with tube settling, micro swirl reaction zone and tube settling district adopt ring structure, make water distribution more even, the more reasonable smoothness of current.And the utility model reduces floor space, improves sedimentation effect, strengthens suspended substance removal efficient.
The utility model device has wide range of applications, and can realize efficiently removing the treatment effect of suspended substance fast, remove efficient far above general flocculation sedimentation tank, and floor space is little, and capacity of resisting impact load is strong, and operation simply is easy to control.
