Problems solved by technology

[0003] TAIC products are usually produced by reacting and polymerizing allyl chloride and cyanate and then undergoing extraction and separation processes. Therefore, the production wastewater contains relatively high concentrations of triallyl isocyanurate TAIC and by-products in the organic reaction process, etc. Refractory organic matter, it is often difficult to meet the discharge standard with traditional wastewater treatment methods

Abstract

The invention provides a method for processing triallyl isocyanurate production wastewater. The method is characterized by comprising the following steps: homogenizing, namely mixing wastewater with domestic sewage for primarily adjusting the quality of the wastewater; ozone oxidation treatment, namely feeding the homogenized wastewater to an ozone reaction pool, generating ozone by adopting an ozone generator, and filling the ozone reaction pool with ozone by adopting a microporous aerator, wherein the ventilation quantity of ozone is 1.0-2.0g / L; resin adsorption, namely adding an acid to the wastewater after ozone oxidation treatment for adjusting the pH to 3-5, and then controlling the flow velocity of the wastewater after the pH is adjusted to 3-5BV / h, so that the wastewater after the pH is adjusted passes through a resin adsorption bed; biochemical treatment, namely adding an alkali to the wastewater passing through the resin absorption bed for adjusting the pH to 6-8, and then sequentially feeding to an anaerobic tower and a biochemical reaction basin to carry out biochemical treatment; finally, sequentially processing by a coagulation reaction pool and a sand filter chamber, thereby achieving the discharge standard.

Description

technical field [0001] The invention relates to the field of industrial sewage treatment, in particular to a method for treating triallyl isocyanurate production wastewater by combining physicochemical treatment and biochemical treatment. Background technique [0002] Triallyl isocyanurate (TAIC) is a multifunctional olefin monomer containing aromatic heterocycles, which is mainly used as modifiers, crosslinking agents and auxiliary agents for various thermoplastics, ion exchange resins and special rubbers. Vulcanizing agent and the intermediate of photocuring coating, photoresist and flame retardant are a kind of fine chemical products with extremely complex uses. [0003] TAIC products are usually produced by reacting and polymerizing allyl chloride and cyanate and then undergoing extraction and separation processes. Therefore, the production wastewater contains relatively high concentrations of triallyl isocyanurate TAIC and by-products in the organic reaction process, et...
