A removal groove is provided at the upper end of the U-shaped trench 1, and the removal groove and the sliding groove 61 are interconnected. The sliding connection of the sliding plate 62, the sliding groove 61, and the mounting groove 211 allows the position of the stirring assembly 6 to be adjusted, which can adapt to the uniform stirring needs of trenches of different widths.

[0041] Embodiment 2: please refer to 6 and Figure 7 On the basis of the embodiment 1, the application provides a technical solution: the temporary storage assembly 7 comprises a fixed frame 71, an upper box body 72, a liquid outlet pipe 73, a butterfly valve 74, a U-shaped plate 75, a water pump 76 and a filter head 77; the fixed frame 71 is fixedly connected to the upper end of the U-shaped ditch 1, the upper box body 72 is slidably arranged on the inner wall of the fixed frame 71, the upper box body 72 is fixedly connected to the two sides of the upper box body 72, the lower end of the protrusion is attached to the upper end of the U-shaped ditch 1, the liquid outlet pipe 73 is fixedly connected to the lower end of the upper box body 72, the butterfly valve 74 is arranged on the liquid outlet pipe 73, the U-shaped plate 75 is fixedly connected to the side end of the fixed frame 71, the water pump 76 is fixedly connected to the inner wall bottom surface of the U-shaped plate 75, one end of the first pipeline is connected to the liquid suction end of the water pump 76, the filter head 77 is installed at the other end of the first pipeline, the filter head 77 is cylindrical and a plurality of filter holes are arranged on the side wall, one end of the second pipeline is installed on the liquid outlet end of the water pump 76, the other end of the second pipeline extends into the inside of the upper box body 72, the fixed frame 71 provides sliding support for the upper box body 72, the protrusion design ensures that the upper box body 72 is stable and does not overturn, the cylindrical filter hole structure of the filter head 77 filters large particle impurities in the extracted liquid, avoids clogging of the first pipeline, the second pipeline and the water pump 76, the water pump 76 and the liquid level sensor are electrically connected to the controller, when the water level is too high, the controller starts the water pump 76 to automatically extract the relatively clean water body in the upper layer for temporary storage, relieves the water flow pressure in the ditch, prevents the precipitating effect from being invalid due to the too rapid water flow, the butterfly valve 74 controls the discharge of the temporarily stored liquid, and realizes dynamic regulation of the water level and optimization of the processing efficiency.

[0042] Working principle: when the water conservancy project wastewater treatment equipment works, first of all, the equipment is built on the U-shaped ditch 1 through the supporting mechanism 2, the first supporting block 21 is inserted into the soil, the sliding limiting plate 27 is used to make the lower end abut against the soil surface, the T-shaped sliding cooperation of the limiting groove 26 and the limiting plate 27 and the right triangle side abutment are used to enhance the installation stability of the equipment on the flow channel.

[0043] Meanwhile, the position and angle of the electric control box 210 can be adjusted through the rotation of the fixing rod 28 and the sliding of the sleeve block 29, which is convenient for maintenance, the controller in the electric control box 210 is electrically connected to the liquid level sensor to receive the water level signal in real time.

[0044] When the water flow enters the U-shaped ditch 1, because the lower end of the filter cover plate 4 is attached to the bottom surface of the ditch and can rotate along the connecting rod 3, the water flow first hits one end of the filter cover plate 4, and then flows around the cylinder 54 to the other end of the filter cover plate 4. In the process, the water flow impacts the filter baffle 53, causing the rotating cylinder 52 to rotate along the shaft 51. The rotation of the filter baffle 53 cushions the impact force of the water body, achieving water flow deceleration.

[0045] At the same time, the first filter screen in the first filter hole of the filter cover plate 4 and the second filter screen in the second filter hole of the filter baffle 53 can intercept larger impurities. Then, the valve body 13 of the dosing mechanism is opened, the medicament in the dosing cylinder 11 is released into the ditch through the dosing pipe 12, and the stirring assembly 6 is started. The motor 65 drives the rod body and the stirring plate 66 to rotate through the coupling, mixes the wastewater and the medicament, and promotes the reaction of pollutants such as suspended solids and heavy metal ions to generate precipitates.

[0046] In addition, the sliding plate 62 can slide along the sliding groove 61 and slide in the mounting groove 211 of the top plate 22 through the bearing plate 64, realizing adjustment of the stirring position along the width direction of the ditch. The sealing cylinder 67 protects the coupling and the rod body from being damaged by wastewater splashing in, and the precipitates generated by the reaction settle on the bottom surface of the U-shaped ditch 1. The filter screen 10 in the groove 9 at both ends of the filter box 8 further filters the water flow. When the liquid level sensor detects that the water level rises to the preset position, the controller triggers the temporary storage assembly 7, and the water pump 76 is started. The suction end of the water pump 76 extracts the relatively clear water body in the upper layer of the ditch through the filter head 77 (cylindrical side wall filter hole structure), and delivers it to the upper box body 72 through the first pipeline and the second pipeline for temporary storage. The protrusions on both sides of the upper box body 72 are attached to the upper end of the ditch to ensure stability. The temporarily stored clear liquid can be discharged through the liquid outlet pipe 73 and the butterfly valve 74, thereby avoiding the influence of too rapid water flow on the precipitation and stirring effect, realizing water level regulation and control under dynamic water flow, and optimizing the pretreatment efficiency.
