Suspended solid discharge equipment for purifying sewer black and odorous water

Abstract

The invention relates to the technical field of water purification, and discloses suspended solid discharge equipment for purifying sewer black and odorous water. The suspended solid discharge equipment comprises a sedimentation pool, a position fixing mechanism, a bottom wall dirt removal mechanism, a floating material salvage mechanism, two sewage discharge wells, two sludge discharge mechanismsand two communication pipes, wherein the position fixing mechanism is embedded in the top portion of the inner wall of the sedimentation pool, the bottom wall dirt removal mechanism is fixed on the middle portion of the position fixing mechanism, and the floating material fishing mechanism is arranged inside the sedimentation pool. According to the present invention, with the suspended solid discharge equipment, the fluidity of the dirt at the bottom portion of the sedimentation pool is increased, such that the dirt at the bottom portion of the sedimentation pool flows to the middle portion of the pool bottom so as to prevent the dirt in the black and odorous water from being adsorbed on the bottom portion of the sedimentation pool; the flow of the water in the sedimentation pool can be driven to separate the suspended solid from the dirt, such that the suspended solid floats upward; and the middle portion of the water can form vortex by stirring the water, such that the suspended solid dispersed on the water surface of the sedimentation pool can be concentrated to the middle portion of the water surface so as to conveniently fish the suspended solid.

Description

technical field [0001] The invention relates to the technical field of water body purification, in particular to a suspended matter discharge device for purifying black and odorous water bodies in sewers. Background technique [0002] 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 conc...

[0002] 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
