Embodiment 2, the washing machine application example for being equipped with waste water water purifier

On the basis of the washing machine wastewater water purifier that embodiment 1 provides, in conjunction with a washing machine, and it is net with water to do washing Change two suites to rewrite together, forms automatic control part, finally coupled, schematic diagram is as shown in figure 5, Fig. 5 In, 100 be washing machine；11 be water purification reuse washing machine water inlet；12 be washing machine wastewater outlet；20 for the utility model with The upper washing machine wastewater water purifier；21 be clearing machine waterwater entrance；22 be water purifier water purification outlet.

In this application example, the initial flux of film operation is as follows:

Level-one membrane module flux reaches 80LMH, and second membrane module reaches 40LMH, when processing laundrywastes total amount reaches 2000L, level-one flux decline to 60LMH, the membrane module flux decline of second level take level-one cleaning and a second level clear to 30LMH After washing, level-one membrane flux substantially returns to 70LMH, and second membrane module does not obviously restore.

Then empty waste water chamber, to waste water chamber in plus 0.1%Na₂CO₃Afterwards, level-one and second level cleaning are carried out then, then one two The flux of grade membrane module substantially returns to the initial flux of film.

In laundry processes, water for cleaning is subjected to purified treatment twice, discharges 20% high strong sewage, and add 20% New water, last time rinse water, then enter water butt, by the first order membrane module processing after, be stored in cleaning water bag, make For the ejected wash water done washing next time.Total water-saving rate reaches 80% or more.
