Embodiment 1

[0043] Embodiment 1 is used for processing launch site laboratory propellant waste water

[0044] Before the launch of the rocket or satellite, it is necessary to test the filled propellant. During the test, the laboratory propellant waste water will be generated by cleaning the test instruments. The waste water is collected in the underground waste water storage tank near the laboratory. It is characterized by high wastewater concentration, high acidity, and long storage time. Most of unsymmetrical dimethylhydrazine is converted into various intermediate products. Generally, COD reaches 200-250mg / L, unsymmetrical dimethylhydrazine concentration is about 10-25mg / L, and pH value is about 3.5~5.0.

[0045] When using a mobile propellant wastewater treatment vehicle to treat laboratory wastewater, first drive the treatment vehicle to the vehicle operation field near the wastewater storage tank. After the car stops, connect the water inlet pipe, water outlet pipe, air outlet pipe...

Embodiment 2

[0048] Embodiment 2 is used to treat the propellant wastewater of the diversion tank of the launch site

[0049] Before the launch of the rocket, a large amount of water will be injected into the diversion tank to reduce the temperature of the diversion tank during launch. After launch, there will be waste water that has absorbed the launch exhaust. The water spray cooling system during launch and the launch tower after launch Washing also introduces residual propellant into the diversion tank wastewater. The wastewater from the diversion tank is characterized by a large amount of water and low concentration of pollutants. Generally, the COD is only 10-50 mg / L.

[0050] When a mobile propellant wastewater treatment vehicle is used to treat diversion tank wastewater, the operation steps are the same as in Example 1, and a water sample (0#) is taken to detect the wastewater quality. The results are shown in Table 3. According to the quality of wastewater, select operation mode ...

Abstract

The invention relates to an environmental protection waste treatment technique, in particular providing a processing method for space propellant wastewater and a movable treatment trolley, employing plasma oxidation technology to combine with process for photo-oxidation to treat propellant wastewater. The movable treatment trolley mainly comprises a trolley body, a working cabin and a treatment device, and the propellant wastewater of each station is treated according to the above method. The invention has the advantages that the treatment technique is reliable in technique and high in treatment efficiency, and is capable of meeting the standard for discharge of the propellant wastewater and reducing the treatment cost greatly, further as employing the movable treatment trolley, the technical problems of mounting and using on the trolley of the device is resolved, and the movable treatment trolley is sound in mobility and simple in management of the operation, which is adapted for pollution treatment of multi-stations of launch site.

Description

technical field [0001] The invention relates to environmental protection waste treatment technology, in particular to a method and device for treating propellant waste water. Background technique [0002] Propellant wastewater mainly comes from satellite and missile launches, cleaning of propellant tankers, storage tanks, pipelines, ground cleaning of propellant warehouses, residual liquid and cleaning wastewater in laboratories, etc. Therefore, the composition of the propellant sewage is relatively complex, which contains not only the high-temperature combustion products of unsymmetrical dimethylhydrazine and dinitrogen tetroxide, but also the decomposition and oxidation products of unsymmetrical dimethylhydrazine and dinitrogen tetroxide at room temperature. The characteristics of propellant wastewater are: the pollutant components in the wastewater are complex, the volume and concentration of the wastewater vary greatly, the toxicity of the wastewater is high, and the pol...
