Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a wastewater treatment device and a method. The wastewater treatment device comprises a first sedimentation tank for settling large particles, a second sedimentation tank for removing oil stains in wastewater and a third sedimentation tank for settling fine particles; the device is integrally arranged; the height of a first partition wall is limited, so that the height is lower than the height of the wastewater surface; and the communication with the first sedimentation tank and the second sedimentation tank is adopted; the water flow area can be enlarged; water flow velocity is reduced, particles in the wastewater are precipitated in the first sedimentation tank and the second sedimentation tank to the maximum extent, at the same time, water waves can be transmitted from the first sedimentation tank to the second sedimentation tank, the oil stain floating on the wastewater surface is adsorbed in an oil adsorption device by the pushing force of the water waves, and the oil stain adsorption effect can be improved without additional external force; the third sedimentation tank can be used for precipitating fine particles again, so that the purpose of removing the fine particles is achieved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a wastewater treatment device and method. Background technique [0002] A hydropower station is a comprehensive engineering facility that converts water energy into electrical energy, also known as a hydropower plant. It includes a series of hydropower station buildings and various hydropower station equipment installed to produce electricity from water energy. During the construction of hydropower stations, the waste water produced has many types, large volume and high concentration of suspended solids. If it is discharged directly without treatment, it will adversely affect the ecological environment of the construction area and the water quality of the downstream river. [0003] The sewage and wastewater generated by hydropower stations are divided into construction period wastewater and operation period wastewater according to time periods, and are di...
