<p>Disclosed are a laundry water cyclic utilization apparatus, a water-saving washing control method, and a cleaning method of a laundry water cyclic utilization apparatus. The apparatus comprises: a washing cylinder, a cyclic water pipeline, a discharge pipeline, and an ultrafiltration membrane component. A water inlet end of the cyclic water pipeline is connected to a water outlet of the washing cylinder. A water outlet end of the cyclic water pipeline is connected to a water inlet of the washing cylinder. The ultrafiltration membrane component has a water inlet end, a first water outlet end, and a second water outlet end. The ultrafiltration membrane component is connected to the cyclic water pipeline through the water inlet end and the first water outlet end, and a gas conveyance apparatus is connected to the water inlet end of the ultrafiltration membrane component. The cyclic water pipeline is further provided with a liquid conveyance apparatus. The discharge pipeline is connected to the second water outlet end of the ultrafiltration membrane component. When a large amount of filth is kept on the ultrafiltration membrane, the apparatus performs air washing on the ultrafiltration membrane and then rinse it with water, which saves rinsing water and makes the cleaning more efficient and thorough as compared with washing with water only.</p> |
