Hexogen production wastewater treatment system and method

Abstract

The invention relates to a hexogen production wastewater treatment system and a hexogen production wastewater treatment method, and belongs to the field of wastewater treatment. The hexogen production wastewater treatment system comprises a pH regulating pool, an anaerobic pond, an anaerobic reactor, a contact oxidation pond, a settling pond, a biological activated carbon pond and a sand filter pond. The system and the method have the advantages that organic matters and nitrate nitrogen in waste water can be fully utilized for increasing the wastewater pH, and the addition quantity of alkali during the neutralization is greatly reduced. Most organic pollutants can be removed through the anaerobic reactor, and in addition, partial pollutants difficult to biochemically degrade are converted into matters capable of being easily utilized by microorganisms. The wastewater is subjected to two-stage aerobic treatment, a biological activated carbon process is utilized for carrying out deep treatment on outlet water of the contact oxidation pond, and the stable standard reaching of the outlet water quality is ensured.

Description

technical field [0001] The invention relates to a system and method for treating waste water produced by RDX, belonging to the field of waste water treatment. Background technique [0002] The scientific name of RDX is 1,3,4-trinitro-1,3,5-triazacyclohexane, also known as cyclotrimethylenetrinitramine, which is a highly explosive High explosives. Commonly used RDX production processes include direct nitrification method and acetic anhydride method. The waste water produced by the acetic anhydride method to produce methogen contains pollutants such as acetic anhydride, acetic acid, urotropine, ammonium nitrate and methogen, some of which have inhibitory effect on microorganisms and have poor biochemical properties. [0003] At present, for the treatment of waste water produced by RDX, the technology that has been applied in practical engineering is mainly the activated carbon adsorption method. This method uses activated carbon adsorption to remove pollutants in wastewater...

AI Technical Summary

Problems solved by technology

However, activated carbon is not easy to regenerate after adsorption and saturation, and requires frequent replacement of new carbon, and the one-time investment and operating costs are very high.

Moreover, the activated carbon after adsorption saturation cannot be treated as general solid waste because it contains substances such as Hexogen, which further increases the treatment cost.
