Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically a wastewater recycling treatment device for coal chemical industry. Background Technology

[0002] Coal chemical enterprises consume large amounts of water and discharge large volumes of wastewater. Wastewater recycling can significantly reduce the use of fresh water. Direct discharge of wastewater generated during coal chemical processes without treatment will cause serious environmental pollution; therefore, recycling is essential. Coal chemical wastewater contains a large number of toxic and harmful substances, such as phenols, ammonia nitrogen, cyanides, and sulfides, which pose potential hazards to the environment and human health. Recycling can effectively remove these harmful substances, reducing environmental pollution. Furthermore, coal chemical wastewater has a complex composition, containing various organic and inorganic substances, making treatment challenging. Recycling can utilize a combination of processes, such as pretreatment, biological treatment, and advanced treatment, to ensure that the wastewater meets discharge standards or reuse requirements.

[0003] An existing wastewater recycling treatment device and process (application number: CN202411976467.X) utilizes a combination of a first filter box, a second filter box, a first filter screen, a second filter screen, a cleaning port, a mounting frame, and fixing components. This allows for direct opening of the cleaning port and sliding of the second filter screen outside the second filter box for cleaning, facilitating timely and efficient cleaning of the filter residue. However, existing wastewater recycling treatment devices used in coal chemical industries still have the following problems during operation:

[0004] The aforementioned wastewater recycling treatment device is equipped with multiple filters for circulating and filtering wastewater. Since the wastewater that has been filtered multiple times needs to be mixed and filtered again with the unfiltered wastewater flowing in, it is easy to cause poor wastewater filtration effect and affect wastewater treatment efficiency, which brings great inconvenience to wastewater treatment. Therefore, it is very necessary to develop a wastewater recycling treatment device for coal chemical industry for use in the existing wastewater treatment field. Utility Model Content

The conveying rod 5201 drives the threaded conveying blades 5202 to rotate, facilitating the transport of waste generated from coal chemical processes. Wastewater from the waste enters the conical funnel 5206 and the drainage pipe 5207 through the drain hole 5205, ultimately flowing into the outlet. Inside the treatment tank 10, large particles of sludge are discharged through the discharge pipe 5204. Disinfectant enters the treatment tank 10 through the disinfection pipe 11. The rotating rod 40 drives the stirring blades 41 to rotate, which helps to mix the sewage and disinfectant. The sewage is located below the partition plate 21 and is blocked by the connecting plate 13 and the assembly plate 12, so that the sewage can only be filtered through multiple filter screens 20. After filtration, the pump 43 is started, so that the water pumping pipe 50 draws out the filtered sewage and then sends it into the treatment tank 10 through the water delivery pipe 51. At this time, the filtered sewage is located above the partition plate 21. The filtered sewage is filtered again through multiple filter screens 20.
