[0015] Figure 4 This is a schematic diagram of the overall structure of the wastewater process drainage system of this utility model. Detailed Implementation

[0016] To make the technical problem solved by this utility model clearer, the present utility model is further described below with reference to embodiments and accompanying drawings. The specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1 to 2 The image shows a specific embodiment of the multifunctional overflow tank of the wastewater process drainage system of this utility model. The multifunctional overflow tank has overflow and anti-backflow functions, and is suitable for drainage systems of commercial or industrial water tanks. It solves the technical defects of traditional water tank drainage systems, and has two uses in one tank, saving costs.

[0018] The multifunctional overflow water tank includes a water-dividing baffle 3 and a water tank body 6. The water-dividing baffle 3 is installed inside the water tank body 6 and divides the water tank body 6 into a first compartment and a second compartment. The side wall of the water tank body 6 is provided with a first concentration wastewater inlet 1 and a second concentration wastewater overflow outlet 2. The first concentration wastewater inlet 1 is connected to the first compartment, and the second concentration wastewater overflow outlet 2 is connected to the second compartment. The bottom of the water tank body 6 is provided with a drainage channel 4, which connects the first compartment and the second compartment. One end of the drainage channel 4 is provided with an external discharge outlet 5.

[0019] In this embodiment, the first concentration wastewater is high-concentration wastewater, typically defined as COD of 40–80 mg / L and sulfate of 3000–6000 mg / L. The second concentration wastewater is low-concentration wastewater, typically defined as COD of 25–50 mg / L and sulfate of 0–20 mg / L. The first / high-concentration wastewater enters the tank body 6 through the first concentration wastewater inlet 1 and is discharged through the first compartment and external outlet 5 via the water divider 3 and drainage channel 4. The second / low-concentration wastewater enters the tank body 6 through the second concentration wastewater overflow outlet 2 and is discharged through the second compartment and external outlet 5 via the water divider 3 and drainage channel 4. This prevents the high-concentration wastewater entering through the first concentration wastewater inlet 1 from flowing into the second concentration wastewater overflow outlet 2, thus avoiding mixing with the low-concentration wastewater.

[0020] Specifically, the water tank body 6 has a first side wall, a second side wall, a third side wall, a fourth side wall, and a bottom surface. The first side wall and the second side wall are arranged opposite to each other, and the third side wall and the fourth side wall are arranged opposite to each other. The water dividing baffle 3 is parallel to the third side wall and the fourth side wall respectively. The first side wall and the bottom surface are connected by the drainage channel 4. The first concentration wastewater inlet 1 is located on the third side wall, and the second concentration wastewater overflow outlet 2 is located on the second side wall.

[0021] The main body of the water tank 6 can be made of stainless steel 304.

[0022] The drainage channel is U-shaped and is lower than the bottom surface and the first side wall to connect the bottom surface and the first side wall.

[0023] like Figures 1 to 2 As shown, the height of the first concentration wastewater inlet 1 is greater than the height of the second concentration wastewater overflow 2. The opening area of ​​the first concentration wastewater inlet 1 is smaller than the opening area of ​​the second concentration wastewater overflow 2.

[0024] like Figure 2 and Figure 3 As shown, low-concentration wastewater, after treatment, enters the first sedimentation tank 12, and high-concentration wastewater, after treatment, enters the second sedimentation tank 14. The multifunctional overflow tank of this invention is installed in the clear water well 7 of the second sedimentation tank 14. After the low-concentration wastewater enters the first sedimentation tank 12, it undergoes sedimentation and stratification, and the supernatant of the low-concentration wastewater flows out from the outlet of the first sedimentation tank 12. When the low-concentration wastewater is in the clear water well, if the water level in the first sedimentation tank 12 is lower than the height of the second concentration wastewater overflow port 2 in the multifunctional overflow tank of this invention, the low-concentration wastewater flows out from the outlet of the first sedimentation tank; if the water level in the first sedimentation tank exceeds the height of the second concentration wastewater overflow port 2 in the multifunctional overflow tank of this invention, the low-concentration wastewater overflows from the second concentration wastewater overflow port 2 into the second compartment and is discharged from the main body of the tank through the external discharge port 5. Figure 4 As shown, specifically, the low-concentration wastewater in the first sedimentation tank 12 enters the overflow drain pipe 11 through the first overflow channel 13, and then enters the clear water well 7 through the inlet 8. After passing through the first water pump 18 at the outlet 9, it reaches the multi-media filter, where it is filtered and becomes reclaimed water for use as makeup water for the workshop's cooling tower. When the workshop does not require water, it overflows and drains through the second concentration wastewater overflow outlet 2 and the external discharge outlet 5. The high-concentration wastewater in the second sedimentation tank 14 flows into the first concentration wastewater inlet 1 through the second overflow channel 10, overflows and drains through the external discharge outlet 5, enters the terminal drainage tank 15, is monitored online by the second water pump 16, and then is discharged in a three-stage process by the third water pump 17.

[0025] The multifunctional overflow tank and corresponding wastewater process drainage system of this utility model have a reasonable structure and can realize the overflow of two types of water, making one tank serve two purposes and effectively solving the risk of high-concentration wastewater overflowing into low-concentration wastewater; through the internal water-dividing baffle and drainage channel, water flow and diversion are facilitated.

[0026] The above descriptions are specific embodiments of this utility model and do not constitute a limitation on the scope of protection of this utility model. Any modifications and variations made to the technical concept of this utility model should be included within the scope of protection of this utility model.
