Abstract

The invention relates to equipment for treating unsymmetrical dimethylhydrazine-containing wastewater. The equipment comprises a wastewater conveying mechanism, a flow detection mechanism, a concentration detection mechanism, a catalyst sampling mechanism, a degradation reaction mechanism and a control mechanism. The degradation reaction mechanism is respectively communicated with the wastewater conveying mechanism and the catalyst sampling mechanism through pipelines, and the degradation reaction mechanism is used for degrading unsymmetrical dimethylhydrazine in the wastewater; and the control mechanism is electrically connected with and controls the wastewater conveying mechanism and the catalyst sampling mechanism, and is used for adjusting the flow of the wastewater and the sampling amount of the catalyst according to the concentration of unsymmetrical dimethylhydrazine in the wastewater. When the concentration of unsymmetrical dimethylhydrazine in the wastewater is large, the flow of the wastewater can be properly reduced and the sampling amount of the catalyst can be increased, and on the contrary, the flow of the wastewater can be properly increased and the sampling amount of the catalyst can be properly reduced. Therefore, the unsymmetrical dimethylhydrazine amount treated in unit time in the degradation reaction mechanism is relatively stable, so that the fluctuation of each discharge index of the treated wastewater is relatively small.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a device for treating wastewater containing unsymmetrical dimethylhydrazine. Background technique [0002] Propellant is the energy source of the rocket engine and the material basis for the development of the aerospace industry. Propellant can be divided into liquid and solid according to its state. The propellant currently used in my country is still mainly binary liquid propellant, and the propellant removes liquid H 2 , Liquid O 2 All of them have varying degrees of toxicity. If they are not handled properly and the protective measures are not effective, rocket propellants and their decomposition products, compound products, The exhaust gas and waste water produced by the combustion products will have a serious impact on operators and the environment. For this reason, the exhaust gas and waste water of the satellite launch center and the aerospace engine test site must...
