Abstract

The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device and a sewage treatment method thereof. The sewage treatment device comprises an anoxic tank, an aerobic tank, two facultative tanks and an MBR film tank which are sequentially arranged, the two facultative tanks are alternately communicated with the aerobic tank, an air diffuser is arrangedin each facultative tank and connected with an air blower through an air pipe, and an air pipe control valve is arranged on each air pipe. And the two facultative tanks are respectively communicatedwith the anoxic tank through a sludge reflux pump. According to the sewage treatment device disclosed by the invention, the facultative tanks for enhanced denitrification by utilizing endogenous respiration are additionally arranged, so that efficient removal of nitrogen pollutants in sewage is realized; sludge subjected to static settlement in the facultative tanks flows back to the anoxic tank,so that deep utilization of a carbon source of the sewage is realized, the denitrification effect is enhanced, the amount of the sludge entering the MBR film tank is reduced, film pollution is alleviated, and relatively high film flux is adopted when an MBR film component is selected to reduce engineering investment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device and a sewage treatment method thereof. Background technique [0002] Membrane Bio-Reactor (MBR for short) is a new water treatment technology combining activated sludge process and membrane separation technology. Replace the secondary settling tank in the activated sludge process with membrane separation technology to efficiently separate solids and liquids. Its separation effect is far better than that of traditional sedimentation tanks. The effluent water quality is good, the suspended solids and turbidity of the effluent are close to zero, bacteria and viruses are greatly removed, and the effluent can be directly reused as non-potable municipal miscellaneous water. In addition, the high-efficiency interception effect of the membrane makes the microorganisms completely trapped in the bioreactor, realizes the complete separation of the hydraul...
