Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for environmental protection engineering. Background Technology

[0002] In the field of water environmental protection, wastewater treatment, as a key link in water resource recycling, directly affects the water ecosystem service function and human water safety. Currently, developing intelligent and efficient wastewater treatment equipment, through process optimization and equipment upgrades, is crucial to achieving the synergistic goals of deep pollutant removal and resource recovery. Meanwhile, solid-liquid separation is a fundamental and critical step in the entire wastewater treatment process. Through solid-liquid separation, suspended solid particles and other insoluble impurities in wastewater can be removed, significantly reducing turbidity and pollutant content, creating favorable conditions for subsequent advanced treatment. Currently, various solid-liquid separation devices for wastewater treatment are available on the market. Traditional gravity sedimentation equipment works on the principle of the density difference between solid particles and liquid; under the action of gravity, solid particles gradually settle to the bottom of the container, achieving initial solid-liquid separation. However, this type of equipment has low processing efficiency, is difficult to effectively separate small particles, and has a long processing time. Filtration-type solid-liquid separation equipment uses filter media such as filter screens and filter cloths to intercept solid particles on one side of the filter media, while the liquid flows out through the media. However, this equipment is cumbersome to operate, has high maintenance costs, and may affect the continuity of wastewater treatment. With increasingly stringent environmental protection requirements, higher demands are being placed on the performance of solid-liquid separation equipment for wastewater treatment. Developing a highly efficient, energy-saving, stable, and adaptable solid-liquid separation system for wastewater treatment has become an urgent priority, which is of great significance for promoting the development of environmental protection projects and achieving the sustainable use of water resources.

[0038] Working principle: When wastewater enters through inlet 24, starting motor 5 causes rotating shaft 6 to rotate with the output end of motor 5, thereby driving straight bevel gear 7 to rotate. Straight bevel gear 8 then rotates with straight bevel gear 7. The rotation of straight bevel gear 8 causes pulley 9 to rotate, which in turn drives belt 10 to rotate. This causes scraper 12 to rotate with belt 10, which in turn drives hook 13 to rotate. This achieves preliminary treatment of the incoming wastewater and removes larger solid waste. The wastewater is then transported further through holes 14 on belt 10.

[0039] When the wastewater further enters the filter tank 3 through the connecting pipe 23, the motor 202 is started, and the aeration tank 15 is started at the same time. The special gas in the aeration pipe 16 treats the wastewater inside the filter tank 3. The output end of the motor 202 drives the rotating shaft 203 to rotate, which in turn drives the connecting plate 205 to rotate. The rotation of the connecting plate 205 agitates the wastewater, making the reaction more complete. Then, through the final filtration of the filter screen 204, the clear water on the top is discharged through the drain pipe 18, and the turbid wastewater continues to be transported to the wastewater tank 1 through the return pipe 19 at the bottom for further filtration.
