Description

Technical Field

[0001] This utility model relates to a mine wastewater treatment technology, and in particular to a multi-stage combined mine wastewater treatment device. Background Technology

[0002] Mine wastewater is a general term encompassing natural dissolved water, dust removal wastewater, mineral processing wastewater, overflow water from mineral processing waste dams, and leachate from slag heaps. To protect the environment, mine wastewater needs to be treated using wastewater treatment equipment to remove sediment, iron ions, and other metal ions, meeting specified requirements before it can be discharged.

[0003] Existing mine wastewater treatment equipment is mostly large-scale equipment. Although it has a good wastewater treatment effect, it is huge in size and extremely expensive. It requires a large flat site for installation and cannot be adapted to the characteristics of the mine.

[0004] Clearly, existing mine wastewater treatment devices suffer from problems such as large size, high cost, and inability to be adapted for selection and combination. Summary of the Invention

[0005] To address the problems of existing mine wastewater treatment devices, such as large size, high cost, and inability to be adapted and combined, this utility model proposes a multi-stage combined mine wastewater treatment device.

[0006] This utility model relates to a multi-stage combined mine wastewater treatment device, comprising an oxidation sedimentation tank and a treatment tank. The oxidation sedimentation tank is a rectangular tank with a filter plate installed in the middle of its inner cavity, a sealed sand outlet at the bottom of its right side wall, and an overflow outlet I on the upper part of its rear wall. The treatment tank is a double rectangular tank connected front to back. The front tank is a plant treatment tank with an inlet on the upper part of its front wall, floating plants planted in the middle of its inner cavity, and an outlet at the bottom of its rear wall. The rear tank is a stone treatment tank with two stone frames installed inside, and an overflow outlet II on the upper part of its rear wall. Furthermore, the overflow outlet I of the oxidation sedimentation tank and the inlet of the plant treatment tank are on the same plane.

[0007] Furthermore, the stone frame is filled with stone particles of different sizes, including one or more of gravel, perlite, zeolite, coarse sand, and fly ash.

[0008] Furthermore, the treatment pools are two or more connected front to back, and the overflow port of the rear wall of the stone treatment pool of the front treatment pool and the inlet port of the front wall of the plant treatment pool of the rear treatment pool are on the same plane.

[0009] Furthermore, both the oxidation precipitation tank and the treatment tank are precast cement structures.

[0010] The beneficial technical effects of this multi-stage combined mine wastewater treatment device are that the multi-stage combination can effectively guarantee the treatment effect, and the use of stone frames can facilitate the selection of filter stones and the activation treatment of the stones.

[0016] The multi-stage combined mine wastewater treatment device of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0017] See Figure 1 , 23, 4, This utility model multi-stage combined mine wastewater treatment device includes an oxidation sedimentation tank 1 and a treatment tank 2; the oxidation sedimentation tank is a rectangular frame, with a filter plate 1-1 in the middle of the inner cavity, a sealed sand outlet 1-2 at the bottom of the right side wall, and an overflow outlet I 1-3 at the top of the rear wall; the treatment tank is a double rectangular frame connected front and rear, wherein the front frame is a plant treatment tank 2-1, with an inlet 2-5 at the top of the front wall, floating plants 2-3 planted in the middle of the inner cavity, and an outlet 2-6 at the bottom of the rear wall; the rear frame is a stone treatment tank 2-2, with two stone frames 2-3 inside the stone treatment tank, and an overflow outlet II 2-7 at the top of the rear wall; and the overflow outlet I of the oxidation sedimentation tank and the inlet of the plant treatment tank are on the same plane. This utility model relates to a multi-stage combined mine wastewater treatment device, employing a combined structure of an oxidation sedimentation tank and a treatment tank. Each treatment tank includes a plant treatment tank and a stone treatment tank. Two stone frames are installed within the stone treatment tank; filter stones are placed in these frames before being placed into the stone treatment tank, and the filter stones in each frame can be different. During treatment, mine wastewater flows in from above the oxidation sedimentation tank, while sand and gravel pass through the filter plates to the bottom of the oxidation sedimentation tank. The wastewater then flows from overflow outlet I on the rear wall of the oxidation sedimentation tank into the plant treatment tank. After plant treatment, the wastewater flows from the outlet at the bottom of the rear wall of the plant treatment tank into the bottom of the stone treatment tank. After being filtered by the stones in the stone treatment tank, the wastewater is discharged from overflow outlet II on the rear wall of the stone treatment tank. The entire process relies entirely on the natural flow of water and requires no power. When a significant amount of sand and gravel accumulates at the bottom of the oxidation sedimentation tank, the sealed sand outlet at the bottom of the right side wall of the oxidation sedimentation tank is opened to remove the sand and gravel, allowing for continued wastewater treatment. When the activity of the filter stones decreases or is lost, the stone frames can be removed from the stone treatment tank manually or by crane, allowing for convenient replacement or reactivation of the filter stones. Therefore, the beneficial technical effects of this multi-stage combined mining wastewater treatment device are that the multi-stage combination effectively ensures the treatment effect, and the use of stone frames allows for convenient selection of filter stones and easy activation treatment of the stones.

[0018] As one of the preferred technical solutions, the stone frame is filled with granular stones of different sizes, including one or more of gravel, perlite, zeolite, coarse sand, and fly ash. To ensure treatment effectiveness, suitable filter stones can be selected based on the composition and content of pollutants in the mine wastewater to improve the wastewater treatment effect.

[0019] As a preferred technical solution, the treatment pools are arranged in pairs or more, connected front to back, with the overflow outlet on the rear wall of the stone treatment pool of the front treatment pool and the inlet on the front wall of the plant treatment pool of the rear treatment pool on the same plane. This allows for the formation of several treatment devices with alternating combinations of plant and stone treatment. Through multi-stage combined plant and stone treatment, and by rationally selecting the plants and stones for each stage, the treatment effect can be effectively improved, thus ensuring that secondary pollution is not caused.

[0020] As one of the preferred technical solutions, both the oxidation sedimentation tank and the treatment tank are precast cement structures. Using precast structures allows for standardized and professional manufacturing, effectively reducing on-site construction costs; furthermore, it facilitates the construction of multi-stage treatment facilities.

[0021] Obviously, the beneficial technical effects of this multi-stage combined mine wastewater treatment device are that the multi-stage combination can effectively guarantee the treatment effect, and the use of stone frames can facilitate the selection of filter stones and the activation treatment of the stones.
