Description

Technical Field

[0001] The utility model relates to the technical field of wastewater filtering devices, and more specifically to automatic filtering equipment for wastewater from a power plant. Background Art

[0002] Thermal power plants rely on water as a medium for transferring energy and as a cooling medium for heat exchange during operation. Water plays an important role in thermal power plants. In the process of thermal power plants, water mainly has two circulation systems: one is the water vapor circulation system in the power equipment; the other is the cooling water circulation system. Therefore, power plants are not only large users of water and drainage, but also large polluters. Although the content of pollutants in the wastewater of thermal power plants is not large, due to the large amount of drainage, the total amount of pollutants discharged also increases accordingly, which will also cause varying degrees of environmental pollution.

[0003] Magnetic coagulation technology is to add magnetic powder to the ordinary coagulation sedimentation process, so that the magnetic powder and floccules are effectively combined, and the floccules and magnetic powder are precipitated more quickly in the sedimentation tank. Its principle is to separate or remove pollutants such as colloids and dispersed particles in the water by means of magnetic field according to the magnetic sensitivity of the substance itself or the addition of magnetic materials. The magnetic coagulation process combines magnetic separation technology with flocculation technology for water treatment. The addition of magnetic powder strengthens the flocculation effect, and the magnetic floccules formed by the special effects of flocculants can settle more quickly.

[0004] The existing magnetic coagulation process has sludge return and magnetic drum facilities. Part of the magnetic powder and flocs after precipitation are returned to the reaction tank for recycling, which saves the amount of coagulant and also increases the sludge concentration in the reaction tank; the other part is separated from the sludge by the magnetic drum, and the sludge enters the sludge treatment unit. The magnetic powder returns to the reaction tank for recycling. When in the reaction tank, it is necessary to filter the sewage through a filtering device to prevent the magnetic powder and flocs from being discharged into the clear water tank. The existing filtering method usually uses a single-layer filter mesh layer, which has a poor filtering effect and also causes the water outlet to be easily blocked by flocs, affecting long-term use.
