[0002] Laundry waste water includes washing waste water, cleaning waste water and dewatering waste water. The water quality characteristics of each laundry waste water are as follows: the washing waste water contains a large amount of short fibers and washing powder foam, has a high COD value and is relatively turbid; the cleaning waste water has a large volume, a small amount of foam, less suspended matter, a small COD value and is relatively transparent; the dewatering waste water has a small volume and the water quality is slightly better than that of the cleaning waste water.

[0003] In the prior art, when the laundry waste water is discharged, it is directly discharged, which is likely to cause environmental pollution. And a large amount of water is needed for washing clothes once, resulting in waste of laundry waste water. The existing laundry waste water treatment devices discharge the waste water after treatment, so that the treated water cannot be reused, resulting in poor recyclability of domestic water.
