Problems solved by technology

[0003] (1) PP filter element filter: a single-tube filter with various PP filter elements inside, but the filter element is easy to block and the filtration accuracy is not high. It is usually used for preliminary filtration of water; although the price is low, it needs to be replaced frequently;
[0004] (2) Activated carbon filter: It mainly eliminates the color and odor in water through the physical adsorption of activated carbon, but cannot remove harmful substances such as bacteria in water. The removal effect of particles with larger particle size is also poor;
[0005] (3) Pressurized and electrified filter: It can effectively remove impurities in water, but beneficial and harmful substances are removed without distinction, and the output is pure water; moreover, the utilization rate of water is low, waste water is much, pure There is little water, generally about 50% of tap water is wasted, the purification cost is high, and the flow rate is small;
[0006] (4) Water softener: Generally, regenerated sodium resin is used to replace calcium and magnesium ions in water, which has a significant effect in softening and reducing water hardness, but cannot purify and effectively remove harmful pollutants in water;
[0007] (5) Ultrafiltration filter: It can effectively remove harmful substances such as sediment, rust, suspended solids, colloids, bacteria, and macromolecular organic matter in water, and retain minerals and trace elements that are beneficial to the human body; the filter element has a long service life and does not need to be powered on , pressurization, low purification cost, but the water output is small, the proportion of wastewater is large, and some ultrafiltration membranes are easy to rupture, and it is not suitable to be found after rupture;
[0008] (6) Mixed media filter: According to the functional characteristics of different filter materials, a combination of various technologies is used to achieve a wide range of water quality treatment and comprehensively and effectively remove various harmful substances in the water; such as Jinliyuan kitchen filter, using Ultrafiltration is the core component, combined with high-performance KDF filter material, not only can effectively remove sediment, rust, suspended solids, colloids, bacteria, macromolecular organic matter, etc. in tap water, but also effectively inhibit the growth of bacteria in water and remove them through KDF Heavy metals, but this measure can easily lead to zinc and copper exceeding the standard; another example is the barrel filter, the barrel-shaped water purifier installed on the water dispenser, generally uses activated carbon, ceramics, mineralization balls and other filter materials, which are completely intercepted. Filtration method, less water waste, but small water volume, low filtration accuracy, inconvenient cleaning, easy to form secondary pollution

Embodiment 1

[0042] Such as figure 1 Shown, a kind of water purification process of the present invention comprises the steps:

[0043] (1) The tap water is transported from the tap water inlet 5 to the first-stage purification treatment device I for the first-stage purification treatment to obtain the first-stage purified water and the first-stage residue, and the gained first-stage purified water is carried out in step (2) ), the resulting first-level residue is discharged through the first-level water outlet 6;

[0044] (2) The first-stage purified water obtained in step (1) is transported to the second-stage purification treatment device II for the second-stage purification treatment to obtain the second-stage purified water and the second-stage residue, and the obtained second-stage purified water It is discharged through the second-stage water outlet 7, and the obtained second-stage residue is discharged through the first-stage water outlet 6;

[0045] Wherein, the water discharged...

Embodiment 2

[0050] Such as figure 2 As shown, a kind of water purification process of the present invention, basic steps are the same as embodiment 1, in order to purify tap water more effectively and make it fully meet people's living needs, specifically, comprise the following steps:

[0051] (1) The tap water is transported from the tap water inlet 5 to the first-stage purification treatment device I for the first-stage purification treatment to obtain the first-stage purified water and the first-stage residue, and the gained first-stage purified water is carried out in step (2) ), the resulting first-level residue is discharged through the first-level water outlet 6;

[0052] (2) The first-stage purified water obtained in step (1) is transported to the second-stage purification treatment device II for the second-stage purification treatment to obtain the second-stage purified water and the second-stage residue, and the obtained second-stage purified water It is discharged through th...

Embodiment 3

[0059] A kind of water purification process basic step of the present invention is the same as embodiment 1 or 2, specifically, as Figure 4 Shown:

[0060] In step (1), in the first-stage purification treatment process, tap water is sequentially subjected to magnetization treatment, ultraviolet sterilization treatment and slow-flow precipitation treatment to obtain first-stage purified water and first-stage residue;

Abstract

The invention relates to a water-purifying process and water-purifying equipment thereof. Tap water is treated into flushing water, clean water and direct drinking water in a grading and classifying manner as required through a first-stage purification treatment device, a second-stage purification treatment device and a third-stage purification treatment device which are connected in sequence from bottom to top. By adopting the water-purifying process and the water-purifying equipment, water resources are utilized more optionally and reasonably, the problems of secondary pollution and the like since heavy metal pollutants in tap water cannot be removed in an efficient and environment-friendly way in the prior art are solved effectively, heavy metal ions, residual chlorine and other harmful particles in tap water are removed efficiently, bacteria are killed, the water quality is improved, sewage is disposed automatically, and the water yield and the utilization ratio of water are increased greatly; the health of a user is ensured; tap water is classified and treated effectively and is utilized in a shunting way according to the water quality, water amount and water pressure requirements of household water, and water is saved; energy is saved efficiently, space is saved, and remarkable energy-saving and environmental protection effects are achieved. The water-purifying process and the water-purifying equipment are suitable to be popularized and applied in relevant tap water treatment field.
