The invention relates to a biological aerated filter, in particular to a high-performance biological aerated filter and aims at solving the technical problem of providing the biological aerated filter which is high in performance, good in filtration effect and controllable in tank temperature, and withhold suspended solid can be cleaned in time. To solve the technical problem, the high-performance biological aerated filter is provided, the high-performance biological aerated filter comprises a reaction tank, a thermal insulation shell, a plate I, lightweight suspended filler, a plate II, a clear water inlet pipe, a valve I, a valve II, a waste water inlet pipe, an air outlet pipe, a valve III, an aerator pipe, a water return pipe, a water pump, a drawing pipe, an air inlet pipe, a pressure sensor, a waste water outlet pipe, a valve IV, a valve V, a clear water outlet pipe and a temperature sensor, and the thermal insulation shell is arranged outside the reaction tank. By means of the high-performance biological aerated filter, the defects that in an existing biological aerated filter, the filtration effect is not good, the withhold suspended solid can not be cleaned in time and the tank temperature is uncontrollable are solved.
Description
technical field [0001] The invention relates to an aerated biological filter, in particular to a high-performance aerated biological filter. Background technique [0002] Biological aerated filter, referred to as BAF, is a new type of biofilm sewage treatment process developed in Europe and the United States in the late 1980s. It was greatly developed in the early 1990s, with a maximum scale of hundreds of thousands of tons per day. This process has the ability to remove SS, COD , BOD, nitrification, denitrification, phosphorus removal, and removal of AOX harmful substances. The biological aerated filter integrates biological oxidation and interception of suspended solids, saves the subsequent sedimentation tank (secondary sedimentation tank), has a large volume load, a large hydraulic load, a short hydraulic retention time, requires less infrastructure investment, and has good water quality. Low energy consumption and low operating costs. [0003] And existing device also...
