[0002] The wastewater produced in the production of cyanate resin contains both trace cyanide radicals and high salt content and high COD. It belongs to industrial wastewater that is difficult to treat. Generally speaking, for industrial wastewater, the content of inorganic salts exceeds 1% (without the conductivity method measure the salt content, but use the incineration method to measure the salt content) will have an impact on biochemistry, and the degree of influence is related to the composition of organic matter in the wastewater; if it exceeds 1.5%, the efficiency of biochemical treatment will be greatly reduced; if it exceeds 2% (B/C (Except for water with a very high value), because the osmotic pressure cannot be balanced, and the waste water also contains traces of biological toxicity cyanide, it is difficult to degrade biochemically;

Abstract

The invention discloses a wastewater treatment process in cyanate ester resin production. The wastewater is filtered to remove solid-phase impurities in the wastewater; then, the wastewater is guidedinto a wastewater treatment device for treatment; the wastewater treatment device comprises a water storage tank, a primary treatment device, a gas inlet mixing device and a secondary treatment device, wherein the water storage tank is used for storing water, adjusting pH and removing part of COD and salt; the primary treatment device is used for reducing COD in the wastewater to a preset standardand reducing the concentration of cyanogen in the wastewater, and the secondary treatment device is used for reducing the concentration of cyanogen in the wastewater and eliminating secondary pollution caused in the process of reducing the concentration of cyanogen, so that the wastewater reaches a discharge standard, and the safety of the discharged wastewater is improved.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to a wastewater treatment process in the production of cyanate resin. Background technique [0002] The wastewater produced in the production of cyanate resin contains both trace cyanide radicals and high salt content and high COD. It belongs to industrial wastewater that is difficult to treat. Generally speaking, for industrial wastewater, the content of inorganic salts exceeds 1% (without the conductivity method measure the salt content, but use the incineration method to measure the salt content) will have an impact on biochemistry, and the degree of influence is related to the composition of organic matter in the wastewater; if it exceeds 1.5%, the efficiency of biochemical treatment will be greatly reduced; if it exceeds 2% (B / C (Except for water with a very high value), because the osmotic pressure cannot be balanced, and the waste water als...
