Problems solved by technology

However, the fatal disadvantage of this method is that the additional addition of organic solvents may form new pollution and cause secondary pollution.
At the same time, additional organic solvents are added, which increases the cost of treating organic oil film pollutants in sewage

The prepared gel material has a good removal effect on alkanes, aromatic compounds, amine compounds, etc. in sewage, and its production process is simple, non-toxic, low in cost, green and environmentally friendly, and has market application prospects. The main components of the gel material include: polypropylene amine, chitosan, 12-hydroxystearic acid, and biphenyl derivatives.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a gel material for treating organic oil film pollutants in sewage and an application method thereof. Background technique [0002] Residual organic solvents and other organic matter in industrial wastewater, COD is generally above 2000 mg / L, and some even as high as tens of thousands or even hundreds of thousands mg / L. Industrial wastewater contains toxic organic substances, mainly aromatic compounds and heterocyclic compounds. In addition, it also contains sulfides, nitrides, heavy metals, etc., and the structure of organic pollutants contained in organic wastewater that is not easy to biodegrade is complex. Wastewater has poor biochemical properties and is toxic to microorganisms, so it is difficult to treat it with general biochemical methods. The waste water emits a pungent stench and has a negative impact on the surrounding environment. In addition, w...
