Background
The overflow weir is one of the common devices in water treatment engineering, and has the functions of maintaining a liquid layer on a plate and enabling the liquid to overflow uniformly. For liquid with a large flow rate, a straight weir is usually adopted, and for a small flow rate, a tooth weir is adopted. In a general water treatment structure or a tower plate structure, a tooth weir is mostly adopted, and the working principle of the tooth weir is as follows: the supernatant layer on the weir turns over from the tooth space to the other side of the weir plate, converges at the other side of the weir plate, converges to one end under the action of gravity, and is then conveyed to the next water treatment structure by the water outlet pipe section.
The catchment power of the water outlet weir is gravity, and the height of the weir is in positive correlation with the flow of the weir in a normal operation range. For a conventional tooth weir, the flow rate of the overflow weir and the height above the weir can be directly obtained by looking up a table. In the use of the actual effluent weir, in order to ensure that water entering the weir is collected in a specified direction, the installation height of the effluent end of the effluent weir is slightly reduced in design. In this case, the weir near the outlet end has a height slightly higher than the weir at the other end, so that the weir plate near the outlet end gets more flow.
In the aspect of the installation, the structure of current play weir is mostly to insert the weir plate on the concrete weir groove that has built, and then the mounting height of weir crest bottom is subject to concrete structure's construction precision, has the inhomogeneous problem of play water, and this kind of play weir makes the region that goes out water many can bring out the suspended solid because of rivers drive effect, influences out water quality of water. Meanwhile, the weir duct is generally a horizontal structure due to the construction property requirements of concrete. Since the flow velocity of the fluid in the horizontal weir is limited, the weir is usually designed to be wide and deep in order to cope with the impact load of the maximum flow. The effluent weir with the structure cannot be applied to water treatment structures and water treatment reactors with high effluent uniformity and limited reserved space.

Examples
The effluent weir provided by the embodiment is applied to the upper part of a biochemical pool of a sewage treatment plant, and the biochemical pool adopts a top overflow drainage mode to discharge water. The dimensions of the effluent weir were calculated as follows:
a 60-degree triangular weir is adopted, the weir passing depth is 5.4cm, and the flow of a corresponding single water outlet weir crest is 3.57m3H; because the selected water outlet weir crest distance is 0.212m, the load on the weir plate per unit length is about 12m3V (m · h); the weir width of the weir plate of the effluent weir is 40cm, and at the moment, if the flow velocity in the weir is 0.46m/s, the water depth in the weir is 15 cm; in order to ensure that the water level in the weir channel does not influence the flow of the overflow water, h which is the distance between the bottom of the weir mouth and the nearest weir plate exceeds the depth of the water in the weir, namely the distance between the bottom of the weir mouth which is the nearest to the movable end and the bottom of the weir plate is 15 cm.
In the water outlet weir, in order to leave a certain safety margin, the vertical height of the end of the adjusting connecting end is 57.5cm, and the distance h from the bottom of the water outlet weir port to the bottom surface of the weir way at the bottom of the weir plate is 40 cm; the designed flow velocity in the weir is 0.46m/s, and the bottom slope of the weir plate is calculated to be 0.12% according to earlier experiments. In the case of the length of the weir plate of the present embodiment, the fixed end should be 10cm higher than the vertical height of the adjustable connecting end, that is, the designed vertical height of the fixed end is 67.5 cm.
In the design of expansion end and wall, single regulation hole length design is 10cm, and the vertical height that the adjustable link of regulation formula was adjusted promptly is about 10 cm. With the aging of operation and the deformation of materials, if the effluent weir inclines, the levelness of the weir plate can be recalibrated by adjusting the height of the adjustable connecting end.
When the water depth of the weir is more than 5.4cm, the flow entering the weir can be discharged as soon as possible, and the situation of siltation in the weir can not be caused. Taking the weir depth of 6.2cm as an example, the flow of a single water outlet weir at the moment is 4.83m3H is used as the reference value. Since the selected weir crest distance is 0.212m, the load on the weir per unit length is about 16.2m3V (m · h); as the weir width of the weir plate of the effluent weir is 40cm, and the flow velocity in the weir is 0.46m/s, the water depth in the weir is 20.25 cm. The distance between the bottom of the water outlet weir port and the bottom of the water outlet weir is still larger than the depth of water in the weir, so the water outlet condition is still good.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
