Embodiment approach

[0035] refer to image 3 , an embodiment of the disk unit, the disk is composed of a plurality of disk units 11 horizontally assembled together, the disk unit has a fan-shaped structure, the surface of the disk unit is concave-convex to form S-shaped corrugations, The edge is welded with a baffle 12 that is higher than the corrugation of the disc. The baffles located in the middle of the right side and the upper left corner of the disc respectively open to form an air outlet 13 and an air inlet 14. The baffle on the side of the air outlet faces the inside of the disc unit. Extending, the integral baffle forms a "G" shape on the surface of the disk unit, and a groove 15 is opened on the top of the baffle on one side of the disk unit.

[0036] The adsorption material is one of fiber bundle filler, fiber ball filler, paper laminated corrugated body filler, epoxy resin, unsaturated polyester resin glass fiber reinforced plastic, polypropylene and polyethylene.

Abstract

The invention discloses a self-aerated biofilm reactor and a sewage treatment system applying the same. The self-aerated biofilm reactor comprises circular ring-shaped disk sheets; a plurality of disk sheets are laminated and fixed together through fixing rods; cylinder structures are hermetically formed by blind plates at two ends of each disk sheet; support frames are fixed on the blind plates at two ends of the disk sheet, and are connected through a central rotating shaft; and an adsorption material is filled and fixed in the hollow portion of each cylinder. The self-aerated biofilm reactor can be mutually combined with a plurality of sewage treatment devices to improve the sewage treatment efficiency. The invention provides the self-aerated biofilm reactor and the sewage treatment system adopting the self-aerated biofilm reactor, is more economical in sewage treatment, saves the resources, and is high in treatment effect.

Description

technical field [0001] The invention relates to the technical equipment field of comprehensive sewage treatment, in particular to a self-aeration biofilm reactor and a sewage treatment system using the reactor. Background technique [0002] At present, the sewage treatment process is basically primary treatment (also called pretreatment), secondary treatment, effluent or water effluent or reuse after advanced treatment. Generally, primary treatment includes grille, grit chamber, and primary sedimentation tank; secondary treatment mainly adopts biological treatment, both anaerobic and aerobic, and activated sludge method is commonly used for domestic sewage. Advanced treatment generally includes biofilm method, filter cloth filter, etc. [0003] The primary sedimentation tank is the main treatment structure of the primary sewage treatment plant, or as a pretreatment structure of the secondary sewage treatment plant, mainly to remove suspended substances in the water. The se...
