Description
Technical field
The present invention relates to a kind of environmental protection air supporting synergist for treatment of dyeing wastewater, belong to waste water in environmental conservation and process
The field of waste water treatment in field, especially dyeing.
Background technology
Air supporting is one of the most conventional water technology, as a kind of quick, efficient, solid-liquid separation skill of low energy consumption
Art, is not only suitable for the water purification that feeds water, is applicable to again the process of various wastewater, particularly to separating miscellaneous close to water of some proportions
Matter is more superior than general settling methods.Pneumatically supported principle is to produce substantial amounts of fine gas bubbles in water, at interfacial tension, bubble
Under the common effect of the many kinds of forces such as rising buoyancy and hydrostatic pressure difference, micro air bubble is promoted to stick to removed impurity particle
On, because adherend density floats to the water surface, so that impurities in water is separated removal less than water.
Dyeing waste water contains the granule of a large amount of different-grain diameters, including clay, antibacterial, virus, humic acid and protein
Deng.Commonly used air supporting method in printing-dyeing waste water treatment process at present, and its design has because water quality situation is different with field condition
Distinguished, be divided into the air supporting used by pretreatment and the air supporting used by end advanced treating after biochemistry before biochemistry.Both air supporting
Waste water in pond all contains the float of multiple different-grain diameter, and major part can use air supporting method to remove, but some because of
The bigger removal efficiency of proportion low (this is also the major reason causing air flotation effect the best).
The principal element of decision air flotation effect is the character of the fine gas bubbles in water, only small at acquisition diameter, density
Greatly, in the case of the good a large amount of fine gas bubbles of uniformity, just can obtain good air flotation effect, reason is:
1, bubble is little, and floating speed is fast, and the disturbance to water body is little, will not crash wadding grain, and can increase bubble and wadding grain collision
Probability.But not bubble is the thinnest more good, and bubble is meticulous to be affected ascent rate and increase size and the cost of flotation tank；
2, bubble diameter is the least, and in bubble, suffered additional pressure is the biggest, the interior collision probability to air molecule to bubble chamber film of bubble
The most, the most violent.Therefore to obtain stable fine bubble, air bubble intensity to ensure；
3, the number of contained microbubble in bubble density, i.e. unit volume outgassing water, determines bubble and the collision that suspends
Probability, density is the biggest, and collision probability is the biggest；
4, the uniformity of bubble, diameter difference and minor diameter bubble including largest air bubbles with minimum bubble account for bubble total amount ratio
Example, increasing of air pocket can reduce daf efficiency.
The research improving treatment of dyeing wastewater solid-liquid separation effect at present is concentrated mainly on the improvement to bubble generator
On, these achieve preferable effect, but often add more processing cost.The method improving solid-liquid separation effect is also wrapped
Include by adjusting the method that flocculant interpolation kind makes the flco proportion of generation reduce, as changed Ferric Salt Flocculants into PAC, PAM
Flocculant etc..Increase bubbles volume in addition with the surfactant adding a small amount of single kind, thus improve solid-liquid separation efficiency
Method.But the surfactant adding single kind is not easily controlled Air Bubble Size, density and uniformity, if add
Surfactant is not suitable for, and even can reduce air flotation effect.
Summary of the invention
For solving deficiency of the prior art, present invention aim at providing a kind of compound, low cost, nontoxic, efficient
Air supporting synergist, there is the generation amount dramatically increasing micro-bubble and the effect of stability, uniformity improving micro-bubble,
Water can be obviously enhanced process, the especially air flotation effect in printing-dyeing waste water treatment process and efficiency.
For achieving the above object, the technical scheme is that a kind of environmental protection air supporting potentiation for treatment of dyeing wastewater
