Novel microbubble oxygenated biological membrane silk and water treatment method

Abstract

The invention discloses a novel microbubble oxygenated biological membrane silk and a water treatment method. The novel microbubble oxygenated biological membrane silk comprises hydrophobic materials,hydrophilic coating and hydrophilic structure reinforced braided fabric. The inner layer of the microbubble oxygenated biological membrane silk is the hydrophobic materials, the middle layer of the microbubble oxygenated biological membrane silk is the hydrophilic coating, the outer layer of the microbubble oxygenated biological membrane silk is the hydrophilic structure reinforced braided fabric, and three layers are mutually bonded into a whole; the hydrophilic coating is coated to the outer surface of the hydrophobic material membrane silk without blocking membrane silk apertures; the hydrophilic structure reinforced braided fabric is adhered to the outer wall, which is coated with the hydrophobic materials, of the membrane silk. After the novel microbubble oxygenated biological membrane silk is adopted, the use ratio of oxygen and the peroxy-molecule ratio and flux of a membrane pore can be effectively improved, the apertures can not be blocked due to the growth of the biologicalmembrane in the membrane silk, meanwhile, the problems of air supply pressure values and the like during oxygen supply can be greatly reduced, multiple targets that oxygen enrichment transferring efficiency is low, power consumption is low, the biological membrane can be easy for growth metabolism and processing efficiency is greatly improved can be realized.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a novel microbubble oxygenated biofilm filament and a water treatment method. Background technique [0002] The biofilm method is a high-efficiency water treatment technology based on biofilms (aerobic microorganisms, concurrent microorganisms, and anaerobic microorganisms) attached to the carrier. In the membrane aeration and oxygenation reaction module, the reaction core module is composed of aeration type hollow fiber membranes, which not only supply oxygen to the biofilm, but also serve as the carrier for the biofilm; Air, the air enters the interior of the hollow fiber membrane, and the air is transported to the water body through the pores of the hollow fiber membrane under a certain aeration pressure; when the air passes through the biofilm on the outer wall of the hollow fiber membrane, it flows into the biofilm Oxygen supply is carried out, so in the...
