The high-load settling tank comprises a tank body and a water inlet pipe, wherein a water collecting tank and a water outlet are formed at the upper part of the tank body, a center reaction cylinder is arranged in the tank body, a mud collecting hopper is communicated with the lower part of the center reaction cylinder, the water outlet of the center reaction cylinder is communicated with the bottom of the tank body through a draft tube, an inclined tube device is arranged below the water collecting tank, a stirrer is arranged in the center reaction cylinder, the power output shaft of the stirrer extends into the center reaction cylinder, and an impeller is arranged at the end part of the power output shaft. The high-load settling tank has the advantages that by addition of a sludge return device, the concentration of colloids in low-temperature and low-turbid water is increased, so that the opportunity that the colloids are condensed and collide is increased, and the size of each colloidal particle is increased; a mechanical stirring device is added, so that the flocculating agent is enabled to be mixed quickly and fully; and certain velocity energy is supplied for raw water, so that the opportunity that particles collide is increased, in this way, unstable colloids can be condensed into floccules with large particles, and can be settled in water and separated.
Description
Technical field
The present invention relates to a kind of water treatment device.
Background technology
Low temperature and low turbidity water has the characteristics such as temperature is low, turbidity is low, oxygen-consumption is low, viscosity is large.Low temperature and low turbidity water is because water temperature is low, and the coefficient of kinetic viscosity of water improves, and in water, particle size is little and size distribution is even, flocculation reaction is slow, little and the free settling not of the flocs unit (alumen ustum) generated, weakened the particle motion of water-borne glue body, reduced between them the probability of collision mutually; The solvation of water-borne glue body strengthens, and circumgranular hydration shell thickening, hinder particle aggregation; Simultaneously, lighter by the formed flco of coagulation, be difficult for sinking, be difficult to separate from water by precipitation.Because turbidity is low, seldom, seldom, proportion is again close to water for the chance of cohesion collision for water-borne glue body impurity, and therefore difficult formation wadding grain, even form, also gently loosen, easy to be broken, and difficult heavy, and the increasing dosage also seldom takes effect.Equipment can really not processed low temperature and low turbidity water now.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art that a kind of a kind of high-load settling tank of innovating for low temperature and low turbidity water is provided.
For achieving the above object, the technical scheme that the present invention takes is: a kind of high-load settling tank, comprise the pond body, water inlet pipe, be provided with water leg, water outlet on Ti top, pond, be provided with the central reaction cylinder in the body of pond, be communicated with and be provided with sludge hopper below described central reaction cylinder, the water outlet of described central reaction cylinder is connected with pond body bottom by guide shell, be provided with inclined tube device below described water leg, be provided with agitator in described central reaction cylinder, the power output shaft of agitator stretches in the central reaction cylinder, in the end of power output shaft, is provided with impeller.
Further, the inner chamber of described sludge hopper is the first mud concentrating and precipitating district, in the sludge hopper bottom, is provided with mud return line, and an end of mud return line is connected with sludge hopper, the other end of mud return line is connected with water inlet pipe, is provided with sludge pump on mud return line.
Further, on described water inlet pipe, be provided with coagulating agent is joined to the water sprayer in former water, in the tangent setting of outer wall of water inlet pipe and described central reaction cylinder, and be connected with the central reaction cylinder.
Further, described central reaction cylinder top is reaction zone, and the bottom of central reaction cylinder is the first suspension zone, and described impeller is arranged in reaction zone.
Further, the training wall that described guide shell is comprised of the outer wall of described central reaction drum outer wall, sludge hopper and the flow deflector be provided with around training wall form, and the inner chamber of described guide shell is the rectification and guide district.
Further, the exit of described guide shell is connected with the second mud concentrating and precipitating district that body bottom in pond is provided with, be provided with concentrated body refuse district above the second mud concentrating and precipitating district, the zone that described concentrated body refuse district surrounds for umbrella shape plate, training wall and the pond body bottom be provided with on the sidewall of described pond body.
Further, above described concentrated body refuse district, be the second suspension zone, described inclined tube device is arranged between the second suspension zone and water leg.
Further, the angle that the sidewall of described umbrella shape plate and pond body forms is the 30-60 degree.
Further, pond body bottom is by being the skew wall of 35-55 degree with level and diapire that the gradient is 1% forms.
The invention has the beneficial effects as follows: increase sludge refluxing apparatus, can increase the concentration of colloid in low temperature and low turbidity water, thereby the chance of the cohesion collision between colloid that is increased makes the size of colloidal solid be increased; Add mechanical stirring device in reactor, can make the quick and complete mixing of flocculation agent, by giving former water extraction for certain energy, increased the collision opportunity of particle.So just make de-steady colloid can form large grain flock and be able to precipitate from water, separate.
