Problems solved by technology

The free end of the capillary membrane in this aquatic grass-type capillary membrane filter faces upwards, and the bottom end is fixed. Under the impact of the air bubbles released from the central cascade trachea, the membrane filaments are entangled and rubbed against the side wall during the swing process, thereby damaging the membrane. silk, causing turbidity in the effluent

Embodiment 1

[0024] An anti-fouling hollow fiber membrane bioreaction module, as attached figure 1 , 2 As shown, the water collection box 1 and 7 hollow fiber membranes 2 are included. The water collection box 1 is located at the bottom, and the hollow fiber membranes 2 are arranged and packaged in the water collection box 1. The inner wall of the lower end of the hollow fiber membrane filament 5 is unblocked. The water collecting box 1 forms a lower potting layer 4, and the lower potting layer 4 is potted with resin, and the resin is urea-formaldehyde resin. The top of each hollow fiber membrane 5 in the hollow fiber membrane 2 is closed, and the upper end of the hollow fiber membrane 2 has an upper end fixing layer 3 to fix the relative positions of the hollow fiber membranes 5 .

[0025] The membrane filaments 5 of the upper fixing layer 3 are fixed by resin sealing, and the width of the sealing resin is 5 cm. The resin is selected as urea-formaldehyde resin, and the strength of the r...

Embodiment 2

[0030] A kind of anti-pollution hollow fiber membrane bioreaction module other parts are the same as embodiment 1, the difference is: as attached image 3 As shown, the fiber rope is woven and fixed between the membrane filaments 5 of the upper fixing layer 3, the number of weaving of the fiber rope is 3, the fiber rope is selected from polyethylene, and the strength is more than 3kg.

[0031] The top of the upper fixed layer 3 is located at 8% of the longitudinal length of the hollow fiber membrane 2 from top to bottom.

[0032] The distance between the diaphragms in the upper fixing layer 3 is 5 mm, and the distance between the diaphragms in the lower potting layer 4 is 3 mm.

[0033] The membrane filaments in the hollow fiber membrane 2 are evenly arranged, and the distance between the membrane filaments is 0.1mm.

Abstract

The invention relates to the technical field of water treatment, and particularly relates to and discloses an anti-pollution hollow fiber membrane biological reaction assembly. The anti-pollution hollow fiber membrane biological reaction assembly comprises a water collecting box and at least one hollow fiber membrane, the water collecting box is located at the bottom end, the hollow fiber membranes are arranged front and back and packaged in the water collecting box, the top end of each hollow fiber membrane wire is closed, and an upper end fixing layer is arranged at the upper end of each membrane to fix the relative positions of the hollow fiber membrane wires. A distance between the hollow fiber membranes is gradually increased from bottom to top, and the front longitudinal section andthe rear longitudinal section of the formed membrane set are in a big-end-up trapezoid shape. The anti-pollution hollow fiber membrane biological reaction assembly is open in the top, so removal of pollutants is benefited; the upper ends of the membrane wires are relatively fixed, fixed gaps are formed among the membrane wires, the upper space of each membrane is wide, and the membrane wires are not prone to generating winding friction in the swinging process, so the pollutants are easy to remove; and the membrane wires are not prone to fracture and dirt blockage, and the membrane assembly hasthe advantages of long service life and high water production efficiency.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an anti-pollution hollow fiber membrane biological reaction module. Background technique [0002] Membrane bioreactor combines membrane separation technology and biological treatment technology to replace traditional secondary sedimentation tank with membrane modules to achieve efficient solid-liquid separation, increase the concentration of activated sludge in the reactor, and improve the quality of effluent water. Hollow fiber membrane modules are widely used in the membrane biological sewage treatment process due to their low price and high packing density, which can effectively intercept colloids, various suspended solid particles, microorganisms, bacteria, viruses and other impurities, and have excellent effluent quality. Conditions of use, there are two types of membrane modules: built-in type (submerged type) and external type; built-in type is to immerse the membr...
