Description

Air floatation treatment device

Technical Field

The utility model relates to a sewage treatment field especially relates to an air supporting processing apparatus.

Background

The air floatation process is widely applied to water treatment, can be used as a pretreatment device in a water treatment system to remove oil substances, suspended substances, colloids and even algae substances in water by an air floatation method, and can also be used in other places in the water treatment process to remove the suspended substances in the water so as to ensure the stable operation of subsequent equipment or processes. The principle of the method is that air bubbles are adhered to pollutants to generate specific gravity difference with water, and the water and the pollutants are physically separated under the action of buoyancy. The most widely used at present is a partial dissolved air flotation process, but the following problems generally exist: 1) the reflux flow is larger and is generally between 25 and 50 percent, and the energy consumption of the reflux booster pump is higher; 2) the utilization rate of the compressed air is low, namely the dissolving efficiency of the air is low, and the consumption of the compressed air is high; 3) can not be according to the water inlet quantity

The dissolved air flow amount is adjusted according to the change of the water quality, and the fluctuation of the effluent quality is large; 4) the slag is removed by adopting a scraper slag scraping method, so that disturbance effect is easily generated on the liquid level, a pollutant back-mixing phenomenon is generated, and the quality of effluent is influenced.

SUMMERY OF THE UTILITY MODEL

To the current situation of the prior art, the utility model aims to solve the technical problem that an air supporting processing apparatus that the backward flow volume is reasonable, the compressed air utilization ratio is high, the row's sediment is simple and convenient is provided.

The utility model discloses a realize like this: an air floatation treatment device is characterized in that: comprises a water taking pump, a dosing tank, a flocculation tank, an air flotation contact chamber, an air flotation separation chamber, a slag discharge groove, a water collecting pipe, a reflux pump, a dissolved air tank, an air compressor, a dissolved air pipe and a releaser; the dosing tank connect the flocculation basin, air supporting contact chamber and air supporting separating chamber between be provided with the baffle of bottom intercommunication, the scum groove set up in the lateral wall upper end of air supporting separating chamber, the collector pipe be located the inside lower extreme of air supporting separating chamber, the backwash pump connect and dissolve gas pitcher upper end, dissolve gas pitcher bottom connect the air supporting contact chamber through dissolving the trachea, dissolve the gas pitcher and connect air compressor.

Preferably, the dosing box is a flocculating agent dosing box.

Preferably, the releaser is connected with a dissolved air pipe.

The utility model discloses a processing procedure as follows: firstly, a coagulant is mixed with wastewater to be treated through adding equipment, then the mixture is extracted into a flocculation tank through a water pump, then the mixture enters an air floatation contact chamber, at the moment, gas in a pressure dissolved gas tank is released into the contact chamber through a dissolved gas releaser, so that the wastewater to be treated is subjected to air floatation contact treatment in the air floatation contact chamber and then is separated in an air floatation separation chamber, the treated water is discharged through a water collecting pipe, and the generated waste residue is discharged through a residue discharge groove.

Compared with the prior art, the utility model, its profitable technological effect as follows: the technical scheme of the utility model can treat in advance that water and flocculating agent carry out the premix, and the backward flow volume does not need too big simultaneously, and compressed air's utilization efficiency is high, and it can in time adjust the dissolved air water yield according to the inflow water yield for the water quality fluctuation is little, and the treatment effect is stable, adopts the scum groove to arrange the sediment simultaneously, can not produce the disturbance to the page or leaf, the pollutant phenomenon of backmixing can not appear.
