Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

The utility model will be further illustrated by specific examples below, but it should be understood that these examples are only used for more detailed description, and should not be construed as limiting the utility model in any form.

As shown in Figure 1, the slow sand filter water treatment device of the present embodiment includes a barrel body 1, a water outlet hole 9, a filter panel 6, an outlet pipe 4 and a filter sand 3; wherein, the water outlet hole 9 is located on the side wall of the barrel body 1, The filter panel 6 is located at the bottom of the barrel body 1, one end of the water outlet pipe 4 is connected to the filter panel 6, and the other end is connected to the water outlet hole 9, and the filter sand 3 is located in the barrel body 1.

In the slow sand filter water treatment device of this embodiment, when first used, water is introduced into the barrel body 1 and left to stand for 8 hours. Under the action of gravity, the water passes through the filter sand layer 3 from top to bottom, and then passes through the device. The filter panel 6 of the filter panel 6, after the secondary filtration, is led to the water outlet 9 through the water outlet pipe 4 to flow out. The outflowing water is poured into the bucket body 1 again, and circulated in turn until the water becomes clear, and the water can be used after becoming clear. Here, the device uses the huge surface area of the filter sand to intercept solid suspended matter and colloids in the water to clarify the water. In addition, while filtering, the adsorption capacity produced by the huge surface area of the filter sand can also be used to absorb dissolved organic matter and heavy metals in the water, and in the interval of filtration, the bacteria and other microorganisms naturally existing in the water can be used to oxidize and decompose the dissolved organic matter , so as to completely degrade the dissolved organic matter into small inorganic molecules such as carbon dioxide and water.

Therefore, the slow sand filter water treatment device of this embodiment can effectively remove harmful impurities in drinking water. In addition, the slow sand filtering water treatment device of the utility model also has the advantages of strong filtering effect, high heat resistance and large capacity.

In the slow sand filtering water treatment device of the present utility model, the bucket body 1 can be 5-20 liters, the filter sand 3 height in the bucket body 1 is lower than the height of the water outlet hole 9, and the filter sand particle size is 0.35～1.2mm. Tee pipe 7 is " T " type pipe. Referring to FIG. 2 , a rectangular hole is arranged in the middle of the filter panel 6 , which fits with the horizontal pipe of the three-way pipe 7 . The water outlet pipe 4 is connected with the water outlet through the water outlet hole 9, and the diameter of the water outlet pipe 4 is 1-5cm. The slow-sand filtering water treatment device also includes an anti-scourr 2, which is located on the upper part of the filter sand 3, and the water inlet 10 is located above the anti-scourr 2. When the water inlet 10 is filled with water, it is ensured that the current will not impact and destroy the filter sand 3 sand layer.

The slow sand filter water treatment device of this embodiment also includes a porous material net 5 with a mesh size of less than 0.25 mm, and the porous material net 5 wraps the filter panel 6 to enhance the filtering effect and protect the filter panel 6 .

In the slow sand filter water treatment device of this embodiment, all plastics are food-grade pp plastics, which have many advantages, such as non-toxic, odorless, tasteless, good chemical stability, high heat resistance, and can be used at 110 ° C It works continuously under the environment, and is particularly stable to water, with a water absorption rate of only 0.01%, which is the first choice for food-grade plastics.

The slow-sand filtering water treatment device of this embodiment can be used by superimposing two or more barrels 1 to increase the cellar water capacity. Here, taking two barrels as an example, cover the two plastic barrels with a barrel cover 11, then stack them together, and connect the two barrels together with an outlet pipe 4 and a tee pipe 7. Drill holes along the upper part of the outer edge of the barrel body 1 wall, and install the leak-proof rubber gasket 8. The same is true for the lower barrel, but a hole needs to be drilled in addition on the outer edge of the barrel wall of the lower barrel for the outlet in the upper barrel. Water pipe 4 enters in the lower bucket. When a plurality of barrels are stacked and used, the connection mode, positional relationship and working principle of each barrel can refer to the above description, and will not be repeated here. The slow sand filtering water treatment device of the present embodiment is provided with a bucket cover 11, which can prevent sand from being irradiated by sunlight and prevent algae from growing.

The slow-sand filter water treatment device of this embodiment, when used again, should take a longer time interval as far as possible. It can be taken to pour 24 liters of cellar water before going to bed, and then pour 24 liters of cellar water into it the next morning, and then wait until noon Refilling with 24 liters of cellar water and maintaining this working frequency can ensure that the microorganisms in the sand grains have sufficient time to oxidize the dissolved organic matter in the water. After 1 to 3 years of use (the specific time varies with water quality and working conditions), a layer of green algae will inevitably be produced on the surface filter sand 3. At this time, this layer of filter sand 3 containing algae can be taken out. Rinse it in water and put it back into the barrel again. The slow sand filter water treatment device of this embodiment, when used in summer, should be placed in a cool place to avoid the phenomenon of plastic becoming brittle and cracked due to direct sunlight on the barrel body; when used in winter, it should be placed indoors to prevent internal water from freezing and causing Damage to the water purification unit.
