Embodiment

[0038] Taking the Oktogen production wastewater discharged from a certain factory as the treatment object, its parameters are: COD=8000±700mg / L, Octogen=80~120mg / L, BOD=2800~3200mg / L, B / C=0.35, pH=4.2-5.1.

[0039] Adopt device and method of the present invention to carry out compound treatment to above-mentioned Oktokin production wastewater; Concrete treatment steps are as follows:

[0040] 1) Discharge the Oktokin production wastewater into the neutralization pool A through the water inlet of the neutralization pool A, set the pH adjustment range of the pH real-time monitoring device in the neutralization pool A to 8, and the Austrian water in the neutralization pool A Ketuojin production wastewater is outside the preset pH adjustment range, and the pH real-time monitoring device controls the alkaline regulator dispensing device to inject alkaline regulators until the pH of the Octogen production wastewater reaches the preset pH adjustment range, the alkaline regulator do...

Abstract

The invention discloses a cyclotetramethylenete-tranitramine production sewage treatment device and a cyclotetramethylenete-tranitramine production sewage treatment method, belonging to the field of sewage treatment. The device comprises a neutralization tank A, an anaerobic tank, an aerobic tank A, a settler A, an acidification tank, an electrocatalysis oxidation tank, a neutralization tank B, a settler B, an aerobic tank B, a settler C, an intermediate water tank, a mechanical filter and an active carbon filter. The method provided by the invention comprises the steps as follows: firstly, most contaminant is removed by adopting a treatment process combining anaerobic biochemical treatment and aerobic biochemical treatment; secondly, the biodegradability of the sewage is improved via an electrocatalysis oxidation treatment unit; thirdly, the most contaminant is removed via an aerobic biochemical treatment unit; lastly, the qualified drainage of outflowing water is ensured via a process combining the mechanical filtration and the active carbon filtration. According to the invention, the process treatment effect is good, the process cost is low, and the indexes of the production sewage of the cyclotetramethylenete-tranitramine treated by adopting the device and the method are changed as follows: COD (Chemical Oxygen Demand) can be lowered below 50 mg / L, and the concentration of the cyclotetramethylenete-tranitramine is lower than 0.5 mg / L.

Description

technical field [0001] The invention relates to a device and a method for treating waste water produced by Octogen, belonging to the field of waste water treatment. Background technique [0002] The wastewater produced by Octojin contains a large amount of nitramine substances, which are chemically stable, difficult to biodegrade, and have inhibitory or toxic effects on microorganisms. At present, there are mainly Fenton's reagent method, activated carbon adsorption method, ozone oxidation method, etc. for the treatment of Oktokin's wastewater. [0003] The Fenton reagent method needs to adjust the pH of the wastewater to 3-4 before the treatment, and then add alkali to neutralize it after the oxidation, and consume a large amount of acid and alkali in the process of acidification and neutralization. In addition, due to the high COD of wastewater, the consumption of ferrous sulfate and hydrogen peroxide is also very large, and a large amount of inorganic sludge is generated...
