Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device with wastewater reuse function. Background Technology

[0002] Wastewater recycling is an important water resource management strategy that involves treating wastewater properly and then reusing it for various purposes to reduce the consumption of fresh water and mitigate environmental pollution.

[0003] Existing wastewater reuse methods include physical, chemical, and biological treatments. However, when wastewater is reused for greening irrigation, purifying it results in a waste of resources. While simple physical filtration can remove some impurities, it cannot treat heavy metals in the wastewater. This leads to some heavy metals being discharged into the irrigated land, affecting soil resources and causing pollution. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides, for example Figure 1-3 The wastewater treatment device shown includes a wastewater reuse function, comprising: a sedimentation tank 1, a dosing tank 2 installed on the top of the sedimentation tank 1, the dosing tank 2 being used to add chemical powder into the inner cavity of the sedimentation tank 1, the inner cavity of the dosing tank 2 being filled with a heavy metal chelating agent, the heavy metal chelating agent forming a chelation reaction with the heavy metals in the water to produce insoluble metal salts, and then separating the solid and liquid to achieve the effect of removing heavy metals from the water; and a sewage pipe is installed on one side bottom of the sedimentation tank 1 to facilitate the discharge of settled sludge.

[0034] It also includes: a connecting pipe 3 and a treatment mechanism 4. The connecting pipe 3 is inserted through one side of the sedimentation tank 1, and the treatment mechanism 4 is installed at one end of the connecting pipe 3. The treatment mechanism 4 is used to treat the wastewater for heavy metals again.

[0035] The treatment mechanism 4 includes a treatment box 41, a retaining plate 42, a filter screen 43, a magnetic suction assembly 44, an adsorbent 45, and a handle 46. A water outlet pipe 5 is installed on one side of the treatment box 41, and a connecting pipe 3 connects to the other side of the treatment box 41. Through the connecting pipe 3, wastewater from the sedimentation tank 1 flows into the inner cavity of the treatment box 41. A drain outlet 6 is installed on one side of the treatment box 41, including a pipe opening and a plug, for discharging sediment from the treatment box 41. A retaining plate 42 is located within the inner cavity of the treatment box 41, and two retaining plates 42 are installed within the inner cavity of the treatment box 41. The filter screen 43 is installed in the middle of one of the retaining plates 42, and the magnetic suction assembly 44 is installed on the other retaining plate. In the middle of another card plate 42, the filter screen 43 and the magnetic suction assembly 44 are used to isolate the flocculated material and the magnetic metal, respectively. The adsorbent 45 is filled at the bottom of the inner cavity of the treatment box 41. The adsorbent 45 includes lime and activated carbon. The lime is used to reduce the solubility of heavy metals, and the activated carbon is used to adsorb heavy metals. The handle 46 is installed on the top of the card plate 42 and fixed to the top of the two card plates 42. By pulling the handle 46, the two card plates 42 can be pulled simultaneously in the inner cavity of the treatment box 41, so that the two card plates 42 can slide out of the inner cavity of the treatment box 41 for cleaning, and the filter screen 43 and the magnetic suction assembly 44 on the card plate 42 can be reused.

[0036] Specifically, the card plate 42 includes: a plate body 421, a lower sealing sleeve 422, an upper sealing sleeve 423, and a sealing strip 424. The plate body 421 is slidably inserted into the inner cavity of the treatment box 41. One of the filter screens 43 is installed in the inner cavity of one of the plates 421. The lower sealing sleeve 422 is fixed to the bottom of the plate body 421, the upper sealing sleeve 423 is fixed to the top of the plate body 421, and the sealing strip 424 is fixed to the side of the plate body 421. The sealing strip 424 is in contact with the inner wall of the treatment box 41. The plate body 421 is inserted and snapped into the bottom of the inner wall of the treatment box 41 through the lower sealing sleeve 422, and the plate body 421 is slidably inserted into the top of the treatment box 41 through the upper sealing sleeve 423. The lower sealing sleeve 422, the upper sealing sleeve 423, and the sealing strip 424 facilitate the tight fit between the card plate 42 and the inner wall of the treatment box 41, thereby improving the tightness of the connection between the card plate 42 and the treatment box 41.

[0037] More specifically, the magnetic attraction component 44 includes a first magnetic rod 441 and a second magnetic rod 442. The first magnetic rod 441 is fixed horizontally to the inner wall of another plate 421, and the second magnetic rod 442 is fixed vertically to the inner wall of another plate 421. The first magnetic rod 441 and the second magnetic rod 442 are spaced apart so that the magnetism between the first magnetic rod 441 and the second magnetic rod 442 does not affect each other. Through the magnetism of the first magnetic rod 441 and the second magnetic rod 442, magnetic heavy metals in the sewage entering the inner cavity of the treatment tank 41 can be magnetically adsorbed by the first magnetic rod 441 and the second magnetic rod 442, thereby reducing the discharge of magnetic heavy metals and reducing the pollution of irrigation land by wastewater.

[0038] Furthermore, a limiting assembly 7 for pressing the plate 42 is installed on the top of the treatment box 41. The limiting assembly 7 includes a limiting block 71 and a limiting plate 72. The limiting block 71 is fixed to the top of the treatment box 41. Multiple limiting blocks 71 are equidistantly fixed to the two ends and the middle of the treatment box 41 by screws. The limiting plate 72 is slidably inserted into the inner cavity of the adjacent multiple limiting blocks 71. Through the limiting plate 72, it is easy to press the plate 421 so that the plate 421 will not slide out of the inner cavity of the treatment box 41 at will, so that the plate 421 can filter the wastewater and make the wastewater stable for irrigation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
