Technical Field

The invention relates to the field of environment-friendly treatment, in particular to a demulsifier for sewage treatment in a leather factory.

Background

The sewage of leather factory is one of industrial waste water which is seriously polluted and difficult to biochemically treat, and is characterized by large discharge capacity, complex water quality components, uneven water quantity, wide pollution related range, oil-containing heavy metal ions, ammonia nitrogen, sulfide, grease, protein and other organic matters in the sewage, strong toxicity, large odor and color. In leather factory sewage treatment, a demulsifier is often required to be added. However, the conventional demulsifier on the market has the problems of narrow application range, low demulsification efficiency, easy corrosion and the like.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the defects of the prior art, the invention provides the demulsifier for treating the sewage of the leather factory, which has wide application range, high demulsification efficiency and difficult corrosion.

The technical scheme is as follows: the demulsifier for treating sewage in a leather factory is characterized by comprising the following components in parts by weight: comprises 10-18 parts of ethanol; 50-60 parts of potassium carbonate; 60-75 parts of a corrosion inhibitor; 80-100 parts of plant ash; 300 portions and 360 portions of alum; 40-75 parts of polyoxypropylene; 300 portions of propylene oxide and 350 portions of propylene oxide; 50-65 parts of soda; 20-28 parts of hexadecyl trimethyl ammonium bromide.

Wherein, the corrosion inhibitor is hydroxyethylidene diphosphonic acid.

Preferably, the composition comprises 15-16 parts of ethanol; 25-27 parts of potassium carbonate; 68-70 parts of a corrosion inhibitor; 90-92 parts of plant ash; alum 330 and 335 portions; 65-68 parts of polyoxypropylene; 330 portions of propylene oxide and 335 portions; 58-60 parts of soda; 24-25 parts of hexadecyl trimethyl ammonium bromide.

The method for preparing the demulsifier comprises the steps of mixing all the materials, stirring and reacting for 12-15 hours at the temperature of 75-95 ℃, and obtaining the demulsifier product.

Has the advantages that: compared with the prior art, the invention has the following remarkable advantages: the demulsifier has wide application range and high demulsification efficiency, and is not easy to cause corrosion.
