Using method of suspended matter discharging equipment for purifying black and odorous water in sewer

Abstract

The invention relates to the technical field of water purification, and discloses a use method of suspended matter discharging equipment for sewer black and odorous water purification. The suspended matter discharging equipment comprises a sedimentation tank, a position fixing mechanism, a bottom wall dirt removal mechanism, a floating matter fishing mechanism, two sewage discharge wells, two sludge discharge mechanisms and two communicating pipes, wherein the position fixing mechanism is embedded in the top of the inner wall of the sedimentation tank, the bottom wall dirt removal mechanism is fixed to the middle of the position fixing mechanism, and the floating matter fishing mechanism is arranged in the sedimentation tank. According to the invention, the flowability of dirt at the bottom of the sedimentation tank is improved, the dirt flows to the middle of the tank bottom, the dirt in black and odorous water is prevented from being adsorbed to the bottom of the sedimentation tank, the water in the sedimentation tank can be driven to flow, suspended matters are separated from the dirt, the suspended matters float upwards, and the water is stirred to enable the middle of the water surface to be vortex-shaped, so that the suspended matters dispersed on the water surface of the sedimentation tank are gathered towards the middle part of the water surface so as to conveniently fish the suspended matters.

Description

[0001] This application is a divisional application with the application date of October 26, 2018 and the application number CN201811259294.4, which is a suspended solids discharge device for purifying sewer black and odorous water. technical field [0002] The invention relates to the technical field of water body purification, in particular to a method for using suspended matter discharge equipment for purifying black and odorous water bodies in sewers. Background technique [0003] As domestic sewage and domestic garbage are continuously discharged into the sewer, the fermentation of domestic sewage and domestic garbage will make the water black and smelly, forming a black and odorous water body. When treating the black and odorous water body, the natural precipitation or coagulation of water It is used to remove the suspended solids in the black and odorous water body, and then settle the dirt in the black and odorous water body to the bottom of the pool. However, the sus...

[0003] As domestic sewage and domestic garbage are continuously discharged into the sewer, the fermentation of domestic sewage and domestic garbage will make the water black and smelly, forming a black and odorous water body. When treating the black and odorous water body, the natural precipitation or coagulation of water It is used to remove the suspended solids in the black and odorous water body, and then settle the dirt in the black and odorous water body to the bottom of the pool. However, the suspended solids in the domestic garbage will be scattered on the water surface, or suspended in the pool, and it is not easy to remove them from the sedimentation tank. Discharge, and the dirt in the black and odorous water body has high viscosity and concentration, poor fluidity, easy to adsorb on the bottom of the sedimentation tank, and difficult to discharge
