Treatment method of (meth)acrylic acid wastewater

Abstract

The invention discloses a treatment method of (meth)acrylic acid wastewater. The method comprises the following steps: adding a vinyl monomer and an initiator into the (meth)acrylic acid wastewater, the wastewater is illuminated to form a gel-form polymer, and the polymer is dehydrated and dried to obtain a high-water-absorptivity material. The treatment method of acrylic acid wastewater has the advantages of low energy consumption, high efficiency and simple process, and can realize recycling of (meth)acrylate production wastewater.

Description

technical field

[0001] Technical Field The present invention relates to the field of chemical technology, in particular to a treatment method for acrylic acid wastewater. Background technique

[0002] The (meth)acrylic acid contained in the industrial wastewater produced in the production of (meth)acrylates is difficult to biodegrade, the treatment cost of the direct incineration method is too high, and the discharge after dilution will cause great damage to the water environment, so it needs to be harmless deal with. The treatment methods for (meth)acrylic acid wastewater include physical methods, chemical methods and biological methods, all of which require multi-step treatment that is time-consuming and high in operating costs.

[0003] The existing treatment method, the application number is CN201710930729.2, and the application date is 20171009 invention patent, which discloses a comprehensive treatment method for acrylate production wastewater, which is obtained by ad...
