Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment equipment, and in particular to wastewater treatment equipment and a process based on coagulation, sedimentation and disinfection. Background Art

[0002] It contains a large amount of suspended solids, colloids, organic matter, pathogenic microorganisms and other pollutants. If it is discharged directly without effective treatment, it will pose a serious threat to the ecological environment of the water body and human health. Therefore, it is of great significance to develop efficient, economical and stable wastewater treatment technology. Coagulation sedimentation and disinfection are the core processes of traditional wastewater treatment. Due to their mature technology, simple operation and low cost, they are widely used in the treatment of municipal sewage, industrial wastewater and recycled water. Coagulation sedimentation is a physical and chemical process that destabilizes and aggregates colloids and suspended particles in wastewater by adding chemical agents to form larger flocs, which are then separated by gravity sedimentation. However, the existing system mostly relies on manual adjustment of the dosage, which is difficult to dynamically adapt to water quality fluctuations, and can easily lead to waste of agents or poor treatment effects. Therefore, we redesigned a wastewater treatment equipment based on coagulation sedimentation and disinfection. Summary of the Invention

S3: The floc absorber (41) controls the opening of the second pump (12), and pumps the wastewater with flocs generated in the coagulation and sedimentation tank (5) into the floc absorber (41) through the absorption pipe (13), filters the wastewater through the floc filter (17), and then controls the circulation pipe (15) to transfer the wastewater to the inside of the coagulation and sedimentation tank (5) through the third pump (14), and the flocs are collected in the floc absorber (41); S4: The water in the coagulation and sedimentation tank (5) is pumped into the disinfection cabinet (23) by controlling the second transmission pipe (25) through the fourth pumping pump (24), and the chlorine water injection pump (28) is controlled to be turned on by the second controller (30). The chlorine water is pumped into the disinfection cabinet (23) by using the uniform injection pipes (29) at multiple positions. The uniform injection pipes (29) at multiple positions facilitate the uniform addition of the chlorine water and ensure the mixing efficiency. S5: The rotation of the power shaft (38) is controlled by the disinfection stirring motor (37), which drives the rotation of the power rotating disk (39), and the disinfection stirring rods (40) at multiple positions are used to stir and mix the water and chlorine water inside the disinfection cabinet (23) for disinfection; S6: After the disinfection process is completed, the third control valve (35) on the storage transmission pipe (34) is opened, and the water treated inside the disinfection cabinet (23) is transmitted to the storage box (36) for storage using the storage transmission pipe (34).
