Abstract
The invention discloses a scale inhibitor for an antibacterial reverse-osmosis membrane for printing and dyeing wastewater. The scale inhibitor comprises 30-40 percent of 1-hydroxyethylidene-1,1-diphosphonic acid, 20-40 percent of dodecyl dimethyl benzyl ammonium chloride, 10-30 percent of potassium borohydride and 20-40 percent of pure water. The formula provided by the invention is a special formula for a printing and dyeing wastewater membrane treatment system and is highly targeted, wherein 1-hydroxyethylidene-1,1-diphosphonic acid and dodecyl dimethyl benzyl ammonium chloride have the effects of preventing inorganic scale and organic scale, potassium borohydride has the functions of restraining bacteria and reducing metallic oxides. Since the three substances are combined together, the scale inhibitor has the functions of preventing inorganic and reducing metallic oxides, is especially applicable to scale inhibition treatment of the antibacterial reverse-osmosis membrane for printing and dyeing wastewater, and has a good scale inhibition effect.
Description
Technical field
The invention belongs to environmental technology field, relate to a kind of sewage treatment drug, particularly the antibacterial reverse osmosis membrane antisludging agent of a kind of dyeing waste water.
Background technology
Dying Wastewater Treatment & is large, and the water yield is large, has now used the more and more of reverse osmosis membrane processing.But most of reverse osmosis membrane antisludging agent is mainly for pollutions such as calcium magne-scale, foundry loams, and dyeing waste water is high organic wastewater, simultaneously because production auxiliary agent and wastewater treatment additive cause a large amount of burning contact scar, therefore existing conventional antisludging agent can not meet the needs that dyeing waste water film processing system is safeguarded.Also lack a kind of special in dyeing waste water film processing system at present, be applicable to the scale inhibition process of the antibacterial reverse osmosis membrane of dyeing waste water, the antisludging agent that scale inhibition effect is good.
Summary of the invention
The object of the invention is to, overcome the deficiencies in the prior art, provide a kind of special in dyeing waste water film processing system, the antibacterial reverse osmosis membrane antisludging agent of the dyeing waste water that scale inhibition effect is good.
The object of the invention is to be achieved through the following technical solutions:
The antibacterial reverse osmosis membrane antisludging agent of a kind of dyeing waste water, wherein each component and mass percentage as follows: HEDP 10-30%, dodecyl benzyl dimethyl ammonium chloride 20-40%, potassium borohydride 10-30%, pure water 20-40%.
Further prioritization scheme: the antibacterial reverse osmosis membrane antisludging agent of above-mentioned dyeing waste water comprises: HEDP 20%, dodecyl benzyl dimethyl ammonium chloride 30%, potassium borohydride 20%, pure water 30%.
The preparation method of the antibacterial reverse osmosis membrane antisludging agent of above-mentioned dyeing waste water: above-mentioned each component is mixed and get final product by said ratio.
Beneficial effect of the present invention:
Compared with prior art, tool has the following advantages in the present invention:
The antibacterial reverse osmosis membrane antisludging agent of dyeing waste water of the present invention, possess the effect of resistance inorganic scale and reducing metal oxide, be applied to the scale inhibition process of the antibacterial reverse osmosis membrane of dyeing waste water, scale inhibition effect is good simultaneously.
Formula of the present invention is a kind of proprietary formula for dyeing waste water film processing system, and specific aim is very strong, and wherein, HEDP, dodecyl benzyl dimethyl ammonium chloride have the effect of resistance inorganic scale and organic deposition, potassium borohydride (KBH
4)) there is the effect of anti-bacteria, reducing metal oxide.The present invention by HEDP, dodecyl benzyl dimethyl ammonium chloride, these three kinds of combinations of substances of potassium borohydride together, give full play to their coordinated effect each other, make it possess the effect of resistance inorganic scale and reducing metal oxide simultaneously, special in a large amount of burning contact scar in dyeing waste water and organic contamination, be specially adapted to the scale inhibition process of the antibacterial reverse osmosis membrane of dyeing waste water, scale inhibition effect is good.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated.
Embodiment 1
The antibacterial reverse osmosis membrane antisludging agent of a kind of dyeing waste water of the present invention, it comprises: HEDP 10%, dodecyl benzyl dimethyl ammonium chloride 40%, potassium borohydride 10%, pure water 40%.
Embodiment 2
The antibacterial reverse osmosis membrane antisludging agent of a kind of dyeing waste water of the present invention, it comprises: HEDP 20%, dodecyl benzyl dimethyl ammonium chloride 30%, potassium borohydride 20%, pure water 30%.
Embodiment 3
The antibacterial reverse osmosis membrane antisludging agent of a kind of dyeing waste water of the present invention, it comprises: HEDP 30%, dodecyl benzyl dimethyl ammonium chloride 20%, potassium borohydride 30%, pure water 20%.
Effect test example
By antibacterial for the dyeing waste water of embodiment of the present invention 1-3 reverse osmosis membrane antisludging agent, be applied to the scale inhibition process of the antibacterial reverse osmosis membrane of dyeing waste water, test.
Application test result shows: add general antisludging agent, and the dirt cycle of blocking up of reverse osmosis membrane is 20-30 days; Add the antisludging agent of formula of the present invention, the dirt cycle of blocking up of reverse osmosis membrane is 30-40 days.
As can be seen here, antisludging agent of the present invention, for the scale inhibition process of the antibacterial reverse osmosis membrane of dyeing waste water, scale inhibition effect is good.
