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.

Embodiment

[0032] Taking Hexogen production wastewater discharged from a factory as the treatment object, its parameters are: COD=6000±700mg / L, Hexogen=30~60mg / L, BOD 5 =2800~3200mg / L, pH=2.2~3.1.

[0033] Adopt device and method of the present invention to carry out compound treatment to above-mentioned Hexogen production wastewater, concrete treatment steps are as follows:

[0034] A kind of processing method of RDX production waste water of the present invention, concrete processing steps are as follows:

[0035] 1) Discharge the waste water produced by Heisuojin into the pH adjustment pool, set the pH adjustment range of the pH real-time monitoring device in the pool to 4-5, control the alkali dosing device to add lye, and adjust the pH of the waste water to 4-5 , stir while adding lye;

[0036] 2) Pump the waste water after the pH value adjustment in step 1 into the anoxic pool, and carry out anoxic reaction and electrochemical reaction in the anoxic pool, and control the oxidatio...

Abstract

The invention relates to a treatment system and method for hexogen production wastewater, belonging to the field of wastewater treatment. The treatment system for hexogen production wastewater comprises a pH regulating tank, an anoxic tank, an anaerobic reactor, a contact oxidation tank, a sedimentation tank, a biological activated carbon tank and a sand filter. In the invention, the wastewater pH is increased by use of the organic matters and nitrate nitrogen in the wastewater, and the addition of alkali for neutralizing is greatly reduced. Most organic pollutants can be removed by the anaerobic reactor, and some biorefractory pollutants are transformed into substances easily utilized by microorganism. The wastewater is subjected to two-level aerobic treatment, advanced treatment is performed on the effluent of the contact oxidation tank by a biological activated carbon technology, and stable and up-to-standard effluent quality is guaranteed.

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...
