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...

Abstract

The invention relates to the technical field of water purifiers, and in particular relates to a micro-wastewater purifier. The micro-wastewater purifier comprises a prefilter, a water inlet electromagnetic valve, a water pump, a filter element mechanism and an RO film which are connected through a pipeline, and further comprises a finite flow and circulating electromagnetic valve, a flow-limiting valve, a one-way valve, a high-pressure switch, a water storage bucket and a post-filter, wherein the prefilter is connected with a raw water pipeline; a purified water outlet of the RO film is connected with a purified water outlet pipe; the one-way valve and the high-pressure switch are sequentially arranged on the purified water outlet pipe along the water flow direction; the water outlet end of the purified water outlet pipe is respectively connected with the water storage bucket and the post-filter; a concentrated water outlet of the RO film is connected with a concentrated water outlet pipe; the water outlet end of the concentrated water outlet pipe is respectively connected with a water return pipe and a drain pipe; the finite flow and circulating electromagnetic valve is arranged on the water return pipe; the water outlet end of the water return pipe is connected with the water inlet end of the water pump; and a flow-limiting valve is arranged on the drain pipe. According to the micro-wastewater purifier, water resources can be saved; the amount of discharged wastewater is small; and the service life of the RO film and the water quality of the purified water are ensured.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a micro-waste water purifier. Background technique [0002] Most cities in my country use Class III surface water, and rural areas mainly use Class IV groundwater as their drinking water source. With the intensification of pollution, problems such as two insects (Giardia flagella, Cryptosporidium), blue-green algae, and heavy metals exceeding the standard, etc., Serious threat to urban and rural drinking water safety. Therefore, surface water and groundwater must be purified before they can be used as drinking water. At present, the core of domestic and commercial drinking water treatment technology is mainly membrane filtration technology. One of them is ultrafiltration membrane filtration, with a filter pore size of 0.01 microns, which can remove all turbid substances (such as sediment, rust, etc.), pathogenic microorganisms (such as parasites, bacteria, viruses, etc.)...
