Abstract
The utility model provides a high-efficiency and complete mixing and reaction multistage efficient flocculation reaction system, which includes a first-stage high-speed stirring mixing pond, a second-stage high-speed stirring mixing pond and a third-stage low-speed stirring reaction pond that are sequentially connected, wherein the third-stage low-speed stirring reaction pond is provided with a water outlet connected with a settling pond. The multistage efficient flocculation reaction system, provided by the utility model, is provided with the second-stage high-speed stirring mixing and the third-stage low-speed stirring reaction, thereby guaranteeing that the system has better shock resistance to fluctuation of coming water quality and water volume, and enabling the system to operate more stably, safely and reliably.
Description
Technical field
The utility model relates to a kind of flocculation reaction device, especially a kind of multi-stage, efficient flocculation reaction system.
Background technology
The coagulating principle depends primarily on three kinds of effects:
(1) compression double electric layer effect
Adsorption layer and diffusion layer are contained in water-borne glue group, are collectively referred to as electrostatic double layer.In electrostatic double layer, cation concentration reduces from inside to outside gradually, and the cation concentration in last and water about equally.Therefore electrostatic double layer has certain thickness.Add a large amount of ionogen as Xiang Shuizhong, its positive ion will be clamp-oned diffusion layer and make it attenuation; And then clamp-on adsorption layer, make the electronegativity reduction on glue core surface.This effect claims compression double electric layer.Compressed when electrostatic double layer, intergranular static is scolded and can will be reduced.When the kinetic energy of being down to less than particle's Brownian movement, particle is adsorption-condensation mutually just.Flocculated particle is easily collision absorption each other in the turbulent flow of water, forms flocs unit (also claiming suede body or alumen ustum).Flocs unit has powerful adsorptive power, can not only adsorb suspended substance, can also absorbed portion bacterium and dissolved matter.Flocs unit is by absorption, and volume increases and sinks.
(2) charge neutrality effect
It is more than the cohesion between micelle of the same race.And the charge neutrality effect refers to that coagulating agent forms the micelle of positively charged in water, thus its can and water in electronegative micelle attract each other and make electrical neutralization each other and condense.For this reason, require both quantities of electric charge will be about equally.
(3) adsorption bridging effect
Some are the high-molecular coagulant adopting of linear structure, and the metallic salt coagulating agent forms linear high polymer in water after, all can the strong adsorption colloidal particle.When the particulate of absorption increased, above-mentioned thread-like molecule was understood flexural deformation and is become net.Thereby play the effect of bridge, make the Distance Shortened between particulate and mutual bonding forms thick flocs unit gradually.This effect claims the adsorption bridging effect.
The utility model content
The utility model provides the multi-stage, efficient flocculation reaction system of a kind of efficient, mixing and sufficient reacting.
Realize a kind of multi-stage, efficient flocculation reaction system of the utility model purpose, comprise one-level rapid stirring mixing pit, secondary rapid stirring mixing pit and three grades of low rate mixing reaction tanks of connecting successively, the water outlet of described three grades of low rate mixing reaction tanks connects settling tank.
The water-in of described one-level rapid stirring mixing pit and three grades of low rate mixing reaction tanks below, water outlet is up; The water-in of described secondary rapid stirring mixing pit up, water outlet below.
The beneficial effect of a kind of multi-stage, efficient flocculation reaction of the present utility model system is as follows:
(1) three grades of flocculation reaction device of the present utility model, owing to being provided with secondary mixing rapid stirring and first order reaction low rate mixing, thereby there is stronger impact resistance in the system that guaranteed to the fluctuation of water water quality and the water yield, makes the operation of system more stable, safety and reliable.
(2) this technique has taken into full account the Variation Features of the sewage quality water yield, and the reasonable setting by three grades of stirrings effectively reduces the operational management cost, makes the maintenance of equipment more easy, and the stability of system's operation is also more secure.
(3) form the characteristics of difficulty for alumen ustum in the coagulating waste water process, taked secondary to stir the technological line that adds respectively flocculation agent and coagulant aids.Compare with the dosing method that adds separately flocculation agent or coagulant aids, secondary offers medicine not only that dosage is much smaller, and that the effect of coagulating sedimentation also will be good is many.
(4) three grades are stirred employing control automatically, have both improved the level of automation of sewage plant, have also alleviated sewage plant operator's labour intensity.
Description of drawings
Fig. 1 is the structural representation of a kind of multi-stage, efficient flocculation reaction of the present utility model system.
Embodiment
As shown in Figure 1, a kind of multi-stage, efficient flocculation reaction of the present utility model system, comprise one-level rapid stirring mixing pit 1, secondary rapid stirring mixing pit 2 and three grades of low rate mixing reaction tanks 3 of connecting successively, the water outlet of described three grades of low rate mixing reaction tanks 3 connects settling tank.
The water-in of described one-level rapid stirring mixing pit 1 and three grades of low rate mixing reaction tanks 3 below, water outlet is up; The water-in of described secondary rapid stirring mixing pit 2 up, water outlet below.
The principle of work of three grades of flocculation reaction device of the present utility model is as follows:
Add flocculation agent in one-level rapid stirring mixing pit, main generation compression double electric layer effect and charge neutrality effect in this pond, add coagulant aids in secondary rapid stirring mixing pit, the adsorption bridging effect occurs in this pond, even do not add coagulant aids in secondary rapid stirring mixing pit, the abundant generation of stirring also helps the abundant generation of compression double electric layer effect and charge neutrality effect, after secondary stirs, enter three grades of low rate mixing reaction tanks, flocculation reaction will fully be occured, and flco is thick closely knit.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; do not breaking away under the spiritual prerequisite of the utility model design; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
