[0001] The utility model belongs to the field of polysilicon production, and in particular relates to wastewater desiliconizing equipment in the polysilicon production process. Background Art
[0002] During the production of silicon materials, a large amount of silicon mud and silicon slag will be generated. These wastes contain a large amount of pollutants, which may pollute the environment if discharged directly. Traditional methods for treating silicon mud and silicon slag mostly use physical or chemical methods to remove large particles of impurities, metal particles and easily separable substances in silicon mud and silicon slag through screening, washing, gravity separation and other methods, and then add acid and alkali solutions or use redox reactions to extract the valuable elements in silicon mud and silicon slag or convert them into a more easily handled form, but there are problems such as low processing efficiency and high cost.
[0003] Removing silica sludge from wastewater is a critical task. Existing methods for removing silica sludge from wastewater also have some disadvantages: (1) High cost: Existing methods for removing silica sludge require expensive chemical reagents or specific equipment, which greatly increases the cost of treatment. This is unaffordable for many companies and small treatment facilities. (2) Technical complexity: Many technologies for removing silica sludge require professional knowledge and technical operations, which makes it difficult for general operators to master and increases the possibility of operational errors. (3) Rapid wear of equipment: Equipment used in the treatment process, especially equipment involving mechanical stirring, pumping and other steps, often wears out quickly and requires frequent maintenance and replacement. (4) Unstable efficiency: Affected by various factors (such as water quality fluctuations, operational errors, etc.), the efficiency of silica sludge removal is often unstable, and it is difficult to ensure continuous treatment effects.

[0031] Combination Figure 3 The top of the filter box 7 is open, and is used to receive the filtered water from the water inlet box 8 above; more than two layers of sewage treatment plates 12, 14 are installed inside the filter box 7.
[0032] An activated carbon filter plate 13 is also installed inside the filter box 7. The activated carbon filter plate 13 is located between two sewage treatment plates 12 and 14 that are adjacent to each other.
[0033] A trapezoidal guide block 15 is also provided at the bottom of the filter box 7, and a drain pipe 16 is installed on the outside of the filter box 7; the slope of the trapezoidal guide block 15 is inclined toward one side of the drain pipe 16; the drain pipe 16 is set at 1 / 2 of the height of the filter box 7.
[0034] The inner side of the sedimentation box 6 and the outer side of the filter box 7 share a wall surface, and the drainage pipe 16 extends into the sedimentation box 6 .
[0035] A drainage pipe 5 is installed on the outside of the sedimentation box 6; the drainage box 4 and the sedimentation box 6 share a wall surface, and the drainage pipe 5 extends into the drainage box 4; the drainage pipe 5 is set at a height of 2 / 3 of the sedimentation box 6.
[0036] Combination Figure 4 A quartz sand net 17 is fixedly connected to the bottom wall of the drainage box 4.
[0037] An inverted "L"-shaped drain pipe 1 is fixedly installed on the outside of the drain box 4, and a control valve 2 is fixedly installed on the upper part of the drain pipe 1; the drain pipe 1 is set at a height of 1 / 2 of the drain box 4.

If there is excess sludge in the drainage box 4, it can be precipitated into the quartz sand net 17. Finally, the control valve 2 is opened to discharge the filtered wastewater through the drain pipe 1.
