[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] like Figure 1-4As shown, a chemical wastewater treatment and recycling device includes a treatment tank 1. A partition 2 is provided in the middle of the treatment tank 1, dividing it into a first area and a second area. The first area is used for wastewater pretreatment, and the second area is used for primary, secondary, advanced, and sludge treatment of the wastewater. A screen 3 and a collection box are provided in the first area. The screen 3 is a chain-type screen, and the collection box is located on the top right side of the screen 3. During wastewater treatment, floating debris falls into the collection box through the screen 3. The collection box includes a bottom mesh 4, side plates 5, and a frame 6. The bottom mesh 4 and side plates 5 are fixedly connected to the inner walls on both sides of the treatment tank 1. There are two side plates 5, located on the upper sides of the bottom mesh 4. The frame 6 is slidably disposed between the bottom mesh 4 and the side plates 5. A zigzag plate 7 is provided inside the frame 6. Since the floating debris contains a certain amount of water and has adhesive properties, the floating debris at the bottom of the collection box easily adheres to the bottom mesh 4. The zigzag plate 7 can scrape off the floating debris on the bottom mesh 4 when the frame 6 is pulled out. The narrow and long shape of plate 7 will not affect the drainage of the bottom net 4. The density of the zigzag lines can be set according to actual needs. The top of the zigzag plate 7 is provided with multiple gripping nails 12. Based on the zigzag plate 7, the gripping nails 12 have a stronger gripping force on floating objects. When the frame 6 is pulled, it has the effect of gripping the floating objects at the bottom of the collection box and moving them together. The gripping nails 12 are short, so the floating objects will not be hooked and fall off after the frame 6 is pulled out. There are two frames 6, which are fixedly connected. There are two zigzag plates 7, which are fixedly connected to the corresponding frames 6. The two zigzag plates 7 are connected. The outer ends of the two frames 6 are provided with connecting plates 8. The connecting plates 8 are set to expand the space so that the collection frame 11 can be placed. The connecting plates 8 are fixedly connected to the support legs 9. The bottom of the support legs 9 is equipped with rollers 10. The treatment pool 1 has an opening for the frame 6 to pass through. The outer side of the treatment pool 1 is provided with a collection frame 11 for collecting floating objects. The outer side of the support legs 9 is equipped with a handle 13.

[0028] Working principle: Chemical wastewater is poured into the first area of ​​treatment tank 1, and the screen 3 is opened. Floating debris in the wastewater rises along the screen 3 and falls into the collection box. When the collection box is almost full, the handle 13 is pulled, moving the current frame 6 outwards. The floating debris moves outwards along with the frame 6, while the other frame 6 simultaneously enters treatment tank 1 and reassembles with the bottom screen 4 and side plates 5 to form a new collection box. This invention can rapidly pre-treat wastewater and has a good treatment effect on conventional floating debris in wastewater. After pre-treatment by the screen 3, the wastewater enters the second area. After primary treatment, secondary treatment, advanced treatment, and sludge treatment, it becomes greywater, also known as reclaimed water, which can be collected and reused within or outside the plant, achieving a cycle.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
