Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment pond for upgrading and transforming a wastewater treatment plant. Background Technology

[0002] With rapid socio-economic development and increasing emphasis on ecological and environmental protection, the national wastewater discharge standards for wastewater treatment plants have become increasingly stringent and stringent. Currently, many wastewater treatment plants in China, due to their early construction, generally face problems such as outdated equipment and relatively backward wastewater treatment technologies, resulting in effluent quality that fails to meet the latest key emission requirements for COD, ammonia nitrogen, total nitrogen, and total phosphorus. Against this backdrop, upgrading existing wastewater treatment systems to meet current wastewater discharge standards has become an inevitable choice for wastewater treatment plants to achieve compliant operation.

[0003] Application number CN202122098617.X discloses a wastewater treatment tank for upgrading a wastewater treatment plant. By activating a first motor and a second motor, the threaded rod of the second motor rotates, driving a sludge-pushing component to slide back and forth at the bottom of the tank, pushing the sludge at the bottom into sludge collection troughs on both sides. The first motor drives a screw feeder to rotate, and then the screw blades deliver the sludge from the sludge collection troughs into a sludge conveying pipe, from which the sludge is discharged out of the tank. This device is not only simple to operate but also saves time and labor. However, in this patent, the sludge pushing requires the rotation of the threaded rod to move the sludge-pushing component into the sludge collection trough. However, the threaded rod is exposed to the sludge, and the adhesion of the sludge affects the movement of the sludge-pushing component. Furthermore, when the discharged wastewater and sludge remain untreated for a long time, their interior dries and hardens, adhering to the screw blades or the sludge collection trough, which also affects the sludge conveying.

An inlet pipe 10 is fixedly connected to the input end of the high-pressure water pump 9, and a delivery pipe 11 is fixedly connected to the output end of the high-pressure water pump 9. A material drop trough 12 is provided on the inner surface of the sewage tank 1.

[0022] Working principle: When it is necessary to clean the sludge in the sewage tank 1, loosen and remove the pipe cover 14, and then start the motor 2 and the high-pressure water pump 9. Under the action of the motor 2, the drive shaft 3 drives the spiral blades 4 to rotate.

Then, it is sprayed out through the through hole 5 on the surface of the drive shaft 3, thereby diluting and softening the sludge that slides into the discharge trough 12, and cleaning the surface of the spiral blades 4, thereby improving the smoothness of sludge discharge.
