The invention provides a self-cleaning method for a water purification module and a washing machine using the method. The self-cleaning method for the water purification module comprises the following steps of starting a self-cleaning program of the water purification module, feeding water into the washing machine to a set level position, successively and repeatedly performing a heating-rinsing program and a clean water replacement and rinsing program, and stopping the heating-rinsing program and the clean water replacement and rinsing program until the water purification module is detected to be thoroughly cleaned, wherein the heating-rinsing procedure comprises the steps of: heating washing water, performing film rinsing, performing standing and performing film gas washing. Through the adoption of the self-cleaning method for the water purification module disclosed by the invention, impurities, macromolecular particles and the like on the surface of a filtration system of the water purification module can be stripped in time, the water purification effect of the water purification module is guaranteed, the service life of the water purification module is effectively prolonged, and the experience of users is greatly improved.

The invention discloses a waste water treatment pipe for a building, belonging to the field of waste water treatment of buildings. The waste water treatment pipe for the building comprises a clear water main pipe and purifying pipes, wherein the clear water main pipe is inserted in the right sides of an upper building floor, a middle building floor and a lower building floor, the upper building floor, the middle building floor and the lower building floor are connected with waste water drain pipes, and the waste water drain pipes are connected with flowmeters. According to the waste water treatment pipe for the building, the waste water in the upper building floor enters the purifying pipe in the middle building floor through the waste water main pipe, the purifying pipe effectively filters and purifies the waste water through a turnover filtering net layer, a turnover sponge filtering net layer, a turnover inorganic filter membrane layer and a hollow fiber permeable membrane, water with different purification degrees is reused through a closestool flushing connecting pipe and a flower-watering connecting pipe, the purified water enters the clear water main pipe through a water outlet pipe and is drained, so that the environmental pollution is effectively reduced, a flushing pipe is utilized for carrying out back flushing on a filtering layer in a clear water pipe by adopting the stored clear water, the treated clear water is resued, so that water resources are saved.

The invention discloses a sewage treatment device, system and method. The device includes a reaction column, an aerator, a water feeder and a water outlet; the reaction column is vertically arranged, with a water feeder below it, an aerator at the bottom, and a water outlet above it. According to the direction of water flow from bottom to top, it includes activated sludge water purification area, biofilm water purification area and clean water area; there is a permeable mud barrier between the activated sludge water purification area and biofilm water purification area. supporting layer. The system includes a plurality of sewage treatment devices connected in series. The method comprises the following steps: (1) start-up stage: inject activated sludge into the reaction column activated sludge area of ​​each sewage treatment device in the sewage treatment system, and carry out stuffy exposure; (2) continuous operation stage: according to the following principles Adjustment: The longer the running time, the greater the water intake and the greater the aeration. The invention has strong load capacity, long backwash cycle, low energy consumption and low sludge discharge.
