The purpose of the utility model is realized as follows: the utility model provides a grit chamber for sewage treatment, includes the cell body, the cell body both sides are equipped with water inlet and delivery port respectively, still be equipped with the grit district in the cell body, be equipped with a plurality of grit chambers and oblique retaining wall in the grit district, lie in water inlet one side in the cell body and still be equipped with buffer and water conservancy diversion district, the grit chamber surface is the echelonment along sewage flow direction and distributes.

Furthermore, the inside wall of the buffer area is provided with a plurality of flow buffering plates which are distributed in a staggered mode, the water inlet is located at the lower end of the buffer area, and the upper end of the buffer area is provided with an opening.

And furthermore, a flow guide opening is formed in one side of the lower end of the flow guide area.

Furthermore, a slow flow net is connected to the outer side wall of the flow guide area and one side of the inclined baffle wall.

Furthermore, the height of the inclined retaining wall is lower than that of the pool body, and the upper end of the inclined retaining wall is also connected with a filter screen inclined to one side of the water inlet.

The utility model has the technical effects that: when carrying out the sewage and deposiing, processing sewage enters into the buffer from the water inlet in, through the potential energy of slow flow board buffering sewage, then flow into the diversion district by the opening part, it deposits in the grit district to enter into by the diversion district lower extreme, it plays the unhurried current effect to be cascaded grit chamber, the effect that has also improved sediment and deposit, then the unhurried current of unhurried current net again, cross the oblique wall discharge after the secondary filtration of filtration and filter screen, the effect of sewage sedimentation has been improved greatly, the follow-up treatment to sewage has been made things convenient for.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present invention will now be described in detail with reference to the accompanying drawings.

The utility model provides a grit chamber for sewage treatment, includes cell body 1, 1 both sides of cell body are equipped with water inlet 2 and delivery port 3 respectively, still be equipped with grit zone 13 in the cell body 1, be equipped with a plurality of grit chambers 4 and oblique barricade 5 in the grit zone 13, it still is equipped with buffer 6 and water conservancy diversion district 7 still to be located water inlet 2 one side in the cell body 1, grit chamber 4 surface is the echelonment along sewage flow direction and distributes.

As shown in fig. 1-2, when settling sewage, let in sewage from water inlet 2, potential energy when entering into buffering sewage in buffer 6, prevent to produce the disturbance to the sewage in grit zone 13, cause the relatively poor condition of sedimentation effect to appear, flow into grit zone 13 from the water conservancy diversion district after the slow flow in, grit chamber 4 that the echelonment distributes can play certain cushioning effect on the one hand, on the other hand can improve the effect of sediment, will originally sediment when preventing follow-up sewage from entering produces the disturbance with impurity, thereby influence the grit effect, sewage overflows inclined retaining wall 5 and discharges through delivery port 3 after the sediment.

According to an embodiment of the present invention, a plurality of baffle plates 8 are disposed on an inner side wall of the buffer area 6 in a staggered manner, the water inlet 2 is located at a lower end of the buffer area 6, and an opening 9 is disposed at an upper end of the buffer area 6. Buffer 6 and buffer 8 set up the potential energy that can effectively cushion when sewage passes through, and water inlet 2 sets up the lower extreme at buffer 6, has increased buffer 6's channel length, has further weakened the potential energy of sewage.

According to one embodiment of the present invention, a diversion opening 10 is provided at one side of the lower end of the diversion area 7. After the slow flow, sewage enters from the lower end of the diversion area 7 and is blocked by the side wall of the stepped grit chamber 4 after further buffering of the grit chamber 4, silt and impurities can be accumulated and precipitated in the grit chamber 4, and the silt and the impurities can also be precipitated in the upward slow flow process.

According to one embodiment of the utility model, a slow flow net 11 is connected to the outer side wall of the flow guide area 7 and one side of the inclined baffle wall 5. The slow flow net 11 not only realizes the effect of slow flow, but also filters sewage, and further removes the silt impurities in the sewage.

According to one embodiment of the utility model, the inclined retaining wall 5 is lower than the tank body 1, and the upper end of the inclined retaining wall 5 is also connected with a filter screen 12 inclined to one side of the water inlet 2. The filter screen further prevents that the silt impurity of not depositing completely from filtering, and the setting of slope makes the silt that filters down slide to the grit chamber 4 of grit zone 13 bottom along retaining wall 5.

The grit chamber for sewage treatment can effectively buffer sewage entering the grit chamber, and prevent the influence on the sewage subjected to internal sedimentation, so that the sedimentation effect is greatly improved, and the subsequent sewage treatment is facilitated.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
