Description

Technical Field

[0002] Environmental governance refers to the process of protecting and improving the natural environment, ecosystem and the quality of human life through a series of laws, policies, technologies and management measures. Wastewater treatment is the top priority of environmental governance. Wastewater treatment usually uses wastewater treatment equipment to remove impurities in wastewater so that the wastewater meets the discharge standards.

[0072] The combination of the ball nut plate 27 and the reciprocating screw 18 is a reciprocating component commonly used in the prior art, that is, the reciprocating screw 18 is provided with two spiral grooves connected end to end and with opposite spiral directions. When the ball nut plate 27 slides on the reciprocating screw 18, the balls inside it slide in the spiral grooves. When sliding in the forward spiral groove, it moves in the forward direction, and when sliding in the reverse spiral groove, it moves in the reverse direction. This part is the prior art and will not be elaborated on here.
