Problems solved by technology

[0004] The traditional treatment process generally uses polyacrylamide as a flocculant, polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, and can reduce the frictional resistance between liquids, but The flocculation and sedimentation time is long, and the flocculation purification effect is general
With the expansion of the scale of aluminum profile factories and the increasingly stringent emission standards, it is difficult for polyacrylamide as a flocculant to meet the needs of current aluminum profile factories. Therefore, it is urgent to provide a composite flocculation with short flocculation settling time and excellent flocculation purification effect. agent

Abstract

The invention discloses a compound-type flocculant for treating wastewater from an aluminum material plant and a preparation method thereof. The compound-type flocculant is characterized by comprising the following components in parts by weight: 20-40 parts of pectin, 20-40 parts of polyacrylamide, 0.2-1 part of anisaldehyde, 5-10 parts of an elderflower extract and 0.3-0.5 part of humic acid. The compound-type flocculant disclosed by the invention has the advantages of good adsorption and flocculation effects and high efficiency, under the condition that a wastewater treatment system is not expanded, larger amounts of waste water can be purified and treated and the treatment requirement of the wastewater from the aluminum material plant.

Description

technical field [0001] The invention relates to the field of aluminum profile sewage treatment, in particular to a composite flocculant for treating waste water in aluminum material factories and a preparation method thereof. Background technique [0002] The production process of aluminum profiles mainly includes degreasing, alkali etching, pickling, oxidation, sealing and coloring of formed aluminum profiles, and the profiles processed by the above processes need to be cleaned with water, resulting in waste water from aluminum profile factories. The wastewater produced by the aluminum profile factory contains not only a large amount of aluminum ions, but also some metal ions such as zinc, nickel, and copper. The pH of the wastewater varies depending on the requirements of various manufacturers, but most of them are acidic. [0003] In view of the characteristics of aluminum profile wastewater mainly containing various metal ions and suspended solids, the traditional treatm...
