Description

Sludge scraper of final settling tank of sewage plant

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to a mud scraper of a final settling tank of a sewage plant.

Background

The final sedimentation tank is an important component of an activated sludge system and mainly used for separating mud from water. And after the mixed liquid is subjected to mud-water separation in the final sedimentation tank, the mud enters a sludge backflow and residual pump room through concentration, and water flows to the next treatment unit through a water outlet. In the design of the final sedimentation tank for water inflow at the periphery and water outflow at the periphery, a central transmission suction dredge is adopted, muddy water enters a water inflow channel at the periphery of the final sedimentation tank through a water distribution well pipeline and enters the tank from a small hole at the bottom of the channel, and floating slag and rotten dead mud in the muddy water float to the surface of the water inflow channel and are accumulated. In the existing design, a scum well is arranged beside a water inlet channel, and a manual gate is arranged on the scum well; and the manual gate is a screw rod type gate, a screw rod of the handle disc is manually rotated to drive a nut seat arranged on the door plate, so that the door plate is driven to be opened and closed up and down, and scum and rotten dead mud are discharged by self-flow. However, when the scum and the rotten dead mud are more, the scum and the rotten dead mud are difficult to discharge into the scum well by self-flowing, and the scum and the rotten dead mud need to be manually stirred to discharge; particularly, when the activated sludge has poor settleability, more floating sludge and floating slag are accumulated, and when the floating sludge and the floating slag cannot be discharged into a floating slag well in time, the effluent quality is seriously influenced.
