Embodiment Construction

[0019] Such as figure 1A treatment system for aviation oil waste water is shown, which is characterized in that the system includes: 1-grid, 2-grit chamber, 3-full effect treatment tank, 4-MBR process, 5-reservoir, 6 - liquid nitrogen storage tank, 7-sodium hydroxide storage tank; wherein, the waste water from cleaning aviation parts is connected to the water inlet of the grid 1 through the pipeline, and the leaves contained in the waste water, the falling off Parts and other sundries are intercepted, and the outlet of the grille 1 is connected to the water inlet of the grit chamber 2 through a pipeline. The waste water is left standing in the grit chamber 2 for 60 minutes. Above, sand and gravel and other particulate matter settle at the bottom under the action of gravity, and an automatic slag scraper is provided at the bottom of the sediment tank 2. After the waste water is discharged, the slag scraper discharges the garbage out of the pool. The water outlet of the grit ch...

Abstract

The invention discloses a treatment system for aviation engine oil waste water. The system comprises a grid, a grit chamber, a full-effect treatment pool, an MBR process, a water storage tank, a liquid nitrogen storage tank, and a sodium hydroxide storage tank. This system is an original design, no oxidizing bacteria and sludge system are installed in the water quality treatment, which avoids the secondary pollution problem in the treatment process. The oil gas produced in the oil separation process is also heated and burned by the system and then decomposed into carbon dioxide and water. The heat energy carried by the combustion products is recycled in the heating process, and at the same time discharged after cooling, improving energy utilization efficiency and reducing calorific value emissions. The separated oil is also recycled as fuel in the system, and the system can also obtain by-product soap.

Description

technical field [0001] The invention relates to a treatment system for aircraft oil waste water, which belongs to the field of waste water treatment in environmental protection. Background technique [0002] Aviation lubricants refer to liquid lubricants used in aircraft engines, instruments and equipment. It can be divided into two categories: petroleum-based lubricating oil (or mineral lubricating oil, referred to as mineral oil) and synthetic lubricating oil. It can also be divided into various types of aviation engine oil and aviation instrument oil according to the purpose. The main functions of all types of engine lubricants are the same, that is, to reduce the mutual friction of friction surfaces; to protect friction parts from chemical and mechanical wear; to absorb frictional heat and transfer it with oil circulation. [0003] The popularity of mechanization has promoted the rapid development of the lubricant industry. According to statistics, the global demand fo...
