Description

Sewage treatment tank

Technical Field

The utility model belongs to the technical field of sewage treatment device and specifically relates to a sewage treatment pond.

Background

The sewage is required to be subjected to three-stage treatment in the sewage treatment process, the primary treatment mainly removes about 30 percent of solid pollutants in a suspended state in the sewage and can not reach the discharge standard, the primary treatment belongs to the pretreatment of the secondary treatment, the secondary treatment mainly removes organic pollutants (BOD, COD substances) in a colloid state and a dissolved state in the sewage, the removal rate can reach more than 90 percent, so that the organic pollutants reach the discharge standard, the tertiary treatment further treats refractory organic matters, soluble inorganic matters and the like which can cause water eutrophication such as nitrogen, phosphorus and the like, the whole process is that the raw sewage passing through a coarse grid passes through a grid or a screen rater, then the sewage enters a sedimentation tank, part of sludge in the sedimentation tank flows back to a primary sedimentation tank, part of sludge enters a sludge tank, then enters a sludge digestion tank, and is dehydrated and dried by equipment, the sludge is utilized finally, but the traditional sedimentation tank needs to be manually operated in the sludge removing process, the work is complicated, and the sludge is easy to rust when mechanical sludge scraping is adopted.

Disclosure of Invention

An object of the utility model is to provide a sewage treatment pond, this sewage treatment pond can play the stationary flow effect well, reaches good sedimentation effect, automatic desilting, efficient long service life.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a sewage treatment pond, includes cell body, water inlet, delivery port and blow off pipe, water inlet and delivery port setting in the cell body both sides, the blow off pipe install in the cell body bottom, cell body bottom be the triangle-shaped design, the delivery port with install the supporting use of slag trap and play water weir in the cell body, the cell body in the average align to grid of water have rotatable swash plate, two swash plates that are located directly over the triangle-shaped apex angle of cell body bottom open and to have the diaphragm orifice, cell body internal surface both sides be provided with the stopper, swash plate bottom be connected with the connecting plate through the hinge, the connecting plate by installing the drive arrangement control in the spout, connecting plate and cell body bottom surface between be the settling zone.

As optimization, the section of the inclined plate is Z-shaped.

Preferably, the inclined plate is made of polytetrafluoroethylene materials.

Preferably, the sewage draining pipe consists of three transversely arranged pipelines and a vertically arranged pipeline.

As optimization, the plate holes are arranged on the edge of the inclined plate and are semicircular holes.

The utility model has the advantages that: compared with the prior art, the utility model discloses a sewage treatment pond reaches stationary flow and better precipitation effect through the swash plate, reaches best stationary flow through connecting plate adjustment swash plate angle and subsides the effect, reaches good blowdown effect through the design of pore and cell body bottom.

Detailed Description

In the embodiment shown in fig. 1-4, the sewage treatment tank comprises a tank body 1, a water inlet 2, a water outlet 3 and a sewage discharge pipe 10, the water inlet 2 and the water outlet 3 are arranged at two sides of the tank body 1, the sewage discharge pipe 10 is arranged at the bottom of the tank body 1, the bottom of the tank body 1 is designed in a triangle shape, the water outlet 2 is matched with a slag baffle 5 and a water outlet weir 4 which are arranged in the tank body 1 for use, rotatable inclined plates 6 are evenly arranged in the water in the tank body 1, plate holes 61 are formed on the two inclined plates 6 which are positioned right above the triangular top angle at the bottom of the tank body 1, two sides of the inner surface of the tank body 1 are provided with limit blocks 7, the bottom of the inclined plate 6 is connected with a connecting plate 8 through a hinge, the connecting plate 8 is controlled by a driving device arranged in the chute 9, and a settling zone 11 is arranged between the connecting plate 8 and the bottom surface of the tank body 1.

In the specific implementation process, sewage enters the tank body 1 from the water inlet 2, water is discharged through the water outlet 3, the water outlet 3 is surrounded by the slag baffle 5, water flows out from the bottom and flows into the space, the effect of blocking scum is achieved, the water outlet weir 4 plays the effect of stabilizing water yield, when sludge does not need to be cleared, the inclined plate 6 adjusts the inclination angle according to the water inflow flow rate, the optimal steady-flow sedimentation effect is achieved, when sludge needs to be cleared, the sludge is accumulated on the inclined plane and the bottom surface (in the sedimentation zone 11) at the bottom of the tank body 1, at the moment, the connecting plate 8 is driven to move in the chute 9 through the driving device, so that the inclined plate 6 rotates to the inclined plate level, the Z-shaped inclined plate 6 is mutually matched through the limiting block to achieve the limiting effect, at the moment, the plate holes 61 of the two inclined plates 6 positioned at the, the bottom surface of the inclined tank body 1 is matched to achieve a good sewage discharge effect, and sludge is discharged through the sludge discharge pipes 10 which are distributed vertically and horizontally.

The above embodiments are only specific cases of the present invention, and the protection scope of the present invention includes but is not limited to the product form and style of the above embodiments, and any suitable changes or modifications made to the sewage treatment tank and the person of ordinary skill in the art according to the claims of the present invention shall fall within the protection scope of the present invention.
