Embodiment 1
[0043] Such as figure 1 As shown, a micro-waste water purifier of the present embodiment includes a pre-filter 10, a water inlet solenoid valve 20, a water pump 30, a filter element mechanism and an RO membrane 50 connected sequentially through pipelines, and the water purifier also includes Flow limiting and circulation solenoid valve 60, flow limiting valve 70, check valve 80, high pressure switch 90, water storage tank 100 and post filter 110,
[0044] The pre-filter 10 is connected to the raw water pipeline 11, the water purification outlet of the RO membrane 50 is connected to the water purification outlet pipe 12, and the one-way valve 80 and the high-pressure switch 90 are sequentially arranged on the water flow direction. A clean water outlet pipe 12, the outlet ends of the clean water outlet pipe 12 are respectively connected to the water storage bucket 100 and the post filter 110;
[0045] The concentrated water outlet of the RO membrane 50 is connected with a conc...
Embodiment 2
[0065] Such as figure 2 As shown, the filter element mechanism of the present embodiment includes a secondary composite filter element 43 and a tertiary composite filter element 44 connected in parallel, and the water outlet ends of the secondary composite filter element 43 and the tertiary composite filter element 44 are connected to the RO membrane 50 respectively. The water inlet end is connected, and the pre-filter 10 is an origami filter element with a pore size of 20 μm. Further, the two-stage composite filter element 43 and the three-stage composite filter element 44 are composite filter elements of activated carbon and PP cotton, the outer layer of the composite filter element is PP cotton with a pore size of 1-5 μm, and the PP cotton is filled with sintered activated carbon .
[0066] The function of the first-stage origami filter element (pre-filter 10) is to filter larger particles in the raw water, so that the entire filtration system can perform coarse filtratio...
