Problems solved by technology

[0004] Although the coal mine sewage treated by the existing technology can be used for toilet flushing, greening, coal washing, power plant circulation, etc., the process is long and the effluent quality is unreliable, so it cannot be used as underground production water

Abstract

The invention provides a device and a method for treating domestic sewage into water for underground production. The device comprises a primary settling tank, a biological oxidation filtration apparatus, an ultrafiltration unit, and a disinfection unit and a clean water tank that are communicated in order along a sewage flow direction. The biological oxidation filtration apparatus is provided with a sewage inlet at the top, and is communicated with the primary settling tank. The bottom of the clean water tank is provided with an outlet of water for production. According to the device and the method for treating domestic sewage into water for underground production provided in the invention, the biological oxidation filtration apparatus is employed to degrade organic matters and ammonia nitrogen in the domestic sewage, the ultrafiltration unit is adopted to remove suspended matters, colloidal substances and coliforms from the domestic sewage, and the disinfection unit is used to ensure that the total of the coliforms and bacterial colonies meets the demands of the water for underground production. The process is short, the treatment facilities are decreased, but also the effluent water has reliable quality.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to a device and method for treating domestic sewage as water for underground production. Background technique [0002] my country's coal mines are mostly distributed in water-scarce areas in the north and northwest. With the rapid development of the coal industry, the contradiction between the supply and demand of water resources for coal mine production water has become more prominent. The domestic sewage of coal mines is treated so that it can become underground production water. To a certain extent, it can alleviate the current water shortage problem in coal mines. [0003] In the prior art, coal mine domestic sewage is mainly subjected to simple biochemical treatment through a simple sewage treatment system. The sewage treatment system includes primary sedimentation tanks, aeration tanks, secondary sedimentation tanks and filter tanks arranged in sequence according to the flow direc...
