Linen washing sewage treatment system and method

Abstract

The invention provides a linen washing sewage treatment system. The system comprises an adjusting tank, a biochemical tank, a sedimentation tank, an aeration system, filtration and adsorption equipment, membrane treatment equipment, disinfection equipment and a clear water tank; a driving pump is arranged in the adjusting tank; a grid is arranged at a water inlet of the adjusting tank; the adjusting tank is communicated with the biochemical tank through a pipeline; active aerobic microorganisms are arranged in the biochemical tank; the aeration system is communicated with the biochemical tank,the biochemical tank is communicated with the sedimentation tank through a pipeline, the sedimentation tank is communicated with the filtration and adsorption equipment through a pipeline, the filtration and adsorption equipment is communicated with the membrane treatment equipment through a pipeline, the membrane treatment equipment is communicated with the disinfection equipment through a pipeline, and the disinfection equipment is communicated with clear water through a pipeline. Due to the arrangement, washing sewage can be repeatedly utilized, the repeated utilization rate of water resources is increased, dissolved salts, colloids, microorganisms, organic matters and the like in the washing sewage can be effectively removed, chemicals do not need to be added, any discharge is avoided, no pollution is generated, the process is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of linen washing, and more specifically, to a linen washing sewage treatment system and method. Background technique [0002] The linen washing process usually uses detergent to clean the linen containing dirt, and through solvents (water, chemicals or dry cleaning agents) at a certain temperature, a certain mechanical force, and a certain period of time, the following effects are played: destroying the bond between dirt and fibers The binding force makes it change from quite firm to loose, forcing the dirt to leave the linen fiber, and the dirt that leaves the fiber loses the ability to recombine with the fiber, and can no longer attach to the fiber. The dirt mixed in the water makes the washing water turbid and can no longer be used. There is no treatment system specially suitable for purifying linen washing sewage in the prior art, which leads to the inability to reuse water resources in the linen washing...
