Abstract

The invention belongs to the field of wastewater treatment, in particular to an oblique plate type membrane-biological integrated wastewater treatment device and a treatment method thereof. The oblique plate type membrane-biological integrated wastewater treatment device comprises a membrane separation system and a biological treatment system, wherein the biological treatment system comprises an anaerobic / anoxic reaction zone and an aerobic reaction zone, a water inlet is formed in the anaerobic / anoxic reaction zone, and an oblique plate settlement water outlet is formed in the aerobic reaction zone; the membrane separation system is connected with the oblique plate settlement water outlet; an aerating system is mounted at the bottom of the aerobic reaction zone, an oblique plate assembly is mounted above the aerating system and comprises multiple parallel oblique plates, and a membrane assembly is mounted below each oblique plate and is parallel to the corresponding oblique plate. According to the wastewater treatment device, the membrane separation system and an oblique plate settlement and activated sludge system form the integrated biological wastewater treatment device, membrane pollution can be effectively reduced while the biological treatment efficiency and the effluent water quality are improved, and the membrane cleaning time is prolonged.

Description

technical field [0001] This patent belongs to the field of waste water treatment, and specifically relates to an inclined plate type membrane-biological integrated waste water treatment device and a treatment method thereof. Background technique [0002] Membrane biological treatment technology is a new type of wastewater treatment technology that combines membrane separation technology and biotechnology. In this technology, the membrane separation system replaces the traditional solid-liquid separation system in the sedimentation tank, saving the space of the sedimentation tank structure, and there is no suspension in the membrane separation water. Solid, effluent water quality is good. Moreover, due to the retaining effect of the membrane on the activated sludge, the hydraulic retention time and the sludge retention time can be controlled separately, which greatly improves the degradation effect of refractory substances. Because the membrane biological treatment process d...
