Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to an immersed membrane distillation assembly and a sewage biological treatment system. The immersed membranedistillation assembly comprises a plurality of membrane distillation units and mounting plates arranged on two sides of the plurality of membrane distillation units; each membrane distillation unit comprises a plastic silk screen arranged in the center, the plastic silk screen is arranged in the middle of a gasket, a supporting plate, the gasket, a microporous hydrophobic membrane, a supporting plate and a assembly frame are sequentially arranged on the left side and the right side of the plastic silk screen from near to far, a plurality of air dispersing through holes are evenly formed in the front side and the rear side of the assembly frame, an air inlet pipe is arranged at the bottom of the assembly frame, and a water distributor is further arranged in the assembly frame. Sewage or mixed liquid is directly sprayed on the microporous hydrophobic membranes through the water distributors, the surface temperature of the microporous hydrophobic membranes on the hot chamber side can beincreased by 10-15 DEG C, and the phenomenon of temperature difference polarization can be effectively weakened.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a submerged membrane distillation component and a sewage biological treatment system thereof. Background technique [0002] Membrane distillation is a membrane separation process that relies on the difference in vapor pressure on both sides of a hydrophobic membrane as the driving force for mass transfer. It has the advantages of general distillation and membrane separation, and can significantly reduce energy consumption by using solar energy or industrial waste heat. In actual operation, the temperature difference between the two sides of the membrane is often used to form a gas-liquid interface on the surface of the membrane pores of the hydrophobic membrane. After evaporation, the water becomes water vapor and passes through the hydrophobic membrane to the cold side, where it is condensed into distilled water for recycling. [0003] Membrane bioreactor is...
