Description

Efficient and environmentally friendly sewage sedimentation tank

technical field

The utility model relates to the field of sedimentation treatment of sewage, in particular to an efficient and environment-friendly sewage sedimentation tank.

Background technique

In the process of sewage treatment, it is necessary to carry out sedimentation treatment for the suspended solids contained in the sewage. The sedimentation treatment of sewage is mainly completed by means of sedimentation tanks. The sedimentation tanks are respectively connected with water inlets and water outlets. The water inlet goes directly to the sedimentation tank, and then it is directly discharged from the outlet after the sedimentation treatment in the sedimentation tank. Large fluctuations will reduce the sedimentation effect. At the same time, when a large amount of sewage is quickly discharged from the sedimentation tank through the water outlet, the sewage in the sedimentation tank will still fluctuate greatly, which will affect the sedimentation effect of the sewage.

Utility model content

In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an efficient and environmentally friendly sewage sedimentation tank, which is used for sedimentation treatment of suspended solids contained in sewage. The residence time in the pool can strengthen the sedimentation effect of suspended solids in sewage.

The technical solution is that the efficient and environment-friendly sewage sedimentation tank includes a sedimentation tank, the inside of which is a cuboid structure cavity, and one end of the sedimentation tank is connected with a water inlet, and the water inlet passes through the first water inlet that slows down the flow rate of sewage. The buffer structure is communicated with the sedimentation tank, and the other end of the sedimentation tank is connected with a second buffer structure for sewage discharge. The inside of the sedimentation tank is provided with multiple sets of buffers for slowing down the flow rate of sewage. Each set of buffers Both consist of a long plate with a rectangular structure and two short plates with a rectangular structure. The first buffer structure includes a first buffer channel and a second buffer channel. The second buffer channel is vertically arranged in the sedimentation tank. and its width is the same as the width of the sedimentation tank, the water inlet communicates with the interior of the sedimentation tank through the first buffer channel and the second buffer channel to realize the step-by-step process of sewage passing through the water inlet Layer buffering realizes the structure of reducing the flow rate of sewage, and the second buffer structure includes a third buffer channel and a fourth buffer channel, both of which are obliquely arranged cuboid structures.

Further, the two ends of the long plate form an equidistant gap with the inner wall of the sedimentation tank, one end of the two short plates is connected with the inner wall of the sedimentation tank, and the gap between the two short plates is With gaps left, each buffer portion is evenly distributed inside the sedimentation tank so that the inside of the sedimentation tank forms a labyrinth structure, and the free ends of each long plate and each short plate form an arc structure.

Furthermore, the degree of inclination of the third buffer channel in the horizontal direction is smaller than the degree of inclination of the fourth buffer channel in the horizontal direction, and a horizontal The transition pipes of the set cuboid structure are connected.

Furthermore, the junctions between the third buffer channel and the transition duct and between the transition duct and the fourth buffer channel form an arc structure.

Furthermore, the height of the second buffer channel is not less than two-thirds of the height of the sedimentation tank, and the connection between the first buffer channel and the second buffer channel forms an arc structure.

The technical effect of the utility model is that each group of buffer parts forms a labyrinth structure inside the sedimentation tank, which effectively prolongs the circulation path of sewage in the sedimentation tank, increases the residence time of sewage in the sedimentation tank, and strengthens the sedimentation of sewage As a result, when the sewage enters the sedimentation tank from the water inlet, it passes through the first buffer structure, which effectively widens the waterway for the sewage to enter the sedimentation tank, so that the sewage can enter the sedimentation tank smoothly, further strengthening the sewage The sedimentation effect, the sewage after sedimentation treatment enters the next treatment process through the second buffer structure, the second buffer structure ensures the smooth outflow of sewage, reduces the fluctuation of sewage in the sedimentation tank, and effectively prevents the sediment in the sedimentation tank from being rolled up.

Detailed ways

The specific implementation will be described in further detail below in conjunction with the accompanying drawings.

Buffer part: the bottom surface of each of the long boards and the short boards is fixedly connected to the bottom of the sedimentation tank, and the distance between each of the long boards and the side wall of the sedimentation tank is not greater than that of the sedimentation tank One-third of the width, the distance between the two short plates of each group of buffer parts is also not greater than one-third of the width of the sedimentation tank, and the heights of each of the long plates and each of the short plates are equal to the height of the The height inside the sedimentation tank is the same. After the sewage enters the sedimentation tank, the buffer part can effectively extend the circulation path of the sewage in the sedimentation tank, thereby prolonging the residence time of the sewage in the sedimentation tank and improving the flow rate of the sewage in the sedimentation tank. The internal sedimentation effect, at the same time, the buffer part can further reduce the flow velocity of the sewage inside the sedimentation tank, prolong the residence time of the sewage in the sedimentation tank, and at the same time reduce the fluctuation of the sewage inside the sedimentation tank, preventing the bottom of the sedimentation tank from The sediment is rolled up by the water flow, further enhancing the sedimentation effect.

First buffer structure: the first buffer channel includes a smaller opening end communicating with the water inlet and a larger opening end communicating with the second buffer channel, and the first buffer channel is used to transfer sewage The water channel is gradually widened from the width of the narrower water inlet to the width of the second buffer channel equal to the width of the sedimentation tank, so as to realize the function that the water flow velocity gradually decreases when the sewage enters the sedimentation tank from the water inlet. The second buffer channel is located at one end of the sedimentation tank and is attached to the side of the sedimentation tank inside the sedimentation tank, and the two ends of the first buffer channel can be elongated ellipses with different widths shape structure, the shape of the water inlet and the end of the second buffer channel is adapted to the end of the first buffer channel, and the second buffer channel is perpendicular to the bottom surface of the sedimentation tank and connected to the sedimentation tank One side of the pool is in contact, and the water channel of the sewage through the water inlet to the first buffer channel and the second buffer channel is gradually widened, so that the water flow velocity is gradually reduced.

Second buffer structure: the side connecting the third buffer channel and the sedimentation tank is opposite to the side where the second buffer channel is connected to the sedimentation tank, and each group of buffer parts is located between the first buffer structure and the second buffer structure Between the two buffer structures, the third buffer channel is nearly parallel to the horizontal plane, the angle between the third buffer channel and the horizontal plane is not more than 30 degrees, and the angle between the fourth buffer channel and the horizontal plane is between 30-60 degrees Between, the connection position between the third buffer channel and the sedimentation tank is close to the bottom of the sedimentation tank, and the sewage enters the next treatment process through the fourth buffer channel.
