Description

Device and method for removing impurities in wastewater Technical Field The application relates to the technical field of sewage treatment, in particular to a device and a method for removing impurities in wastewater. Background The impurities in the wastewater generally comprise solid state, dissolved state, state and other various existing forms, and the wastewater is generally treated by physical, chemical and biological methods in the wastewater treatment process so as to purify the wastewater to reach the dischargeable standard, thereby reducing the environmental pollution or reaching the wastewater recovery and reuse standard so as to save water resources. The physical treatment of wastewater generally adopts physical means to remove some floaters or fine suspended matters and other impurities in the wastewater, chemical treatment mainly comprises adding chemical agents into the wastewater, separating and removing pollutants in a dissolved state in the wastewater or converting the pollutants into harmless substances through mass transfer, and biological treatment mainly comprises using an aerobic biological treatment method, and converting the pollutants into stable and harmless substances in a solution, colloid and fine suspended state in the wastewater through microorganisms. At present, when impurities in wastewater are physically treated, larger floaters in the wastewater are firstly intercepted and salvaged through a coarse grid or a screen, then the wastewater is led into a sedimentation tank for sedimentation, the sedimented wastewater flows out through an overflow port on the sedimentation tank and enters the next link for chemical and/or biological treatment, however, when the wastewater enters the sedimentation tank, a certain impact force is formed on the sedimented wastewater in the sedimentation tank, so that the sedimented sediment is lifted again, or part of sediments which are not timely precipitated directly flow out of the sedimentation tank along with water flow and enter the next link, and the cleaning effect of the impurities in the wastewater is affected.
