Embodiment Construction

[0028] In Fig. 1, a high-strength elastic filler (7) is formed by twisting two strands of iron wire (1) covered with single-layer plastic wire (2). In order to ensure sufficient strength and service life, the iron wire usually adopts ordinary iron wire or stainless steel wire with a surface treatment of ≥2.8mm. In order to ensure that the plastic wire has a certain strength and there is a certain gap between the plastic wires, a PP plastic wire with a length of 0.7-0.9mm and a length of about 12cm is generally used. After being made, the filler is 0.8-1.0m long and 12cm long.

[0029] In Fig. 2, the circular frame (3) is welded by angle steel or stainless steel, and then the dividing plate (4) is installed on the steel frame. The partition is a thin steel plate of 2-4mm, welded to the steel frame, and then drill a 7-8mm round hole for packing at the designed position. If ordinary angle steel or steel plate is used, derusting and anti-corrosion treatment should be carried ...

Abstract

The invention discloses a rotating biological contactor, which adopts elastic filler with high strength to replace a disk sheet, thereby solving the problems of difficult processing, high cost and low treatment efficiency. Because the length of the filler is normally smaller than the designed length the rotating contactor, the rotating contactor is divided into a plurality of units; a plurality of air passages are arranged to greatly lower the possibility of causing anaerobic situation and producing niff for the rotating biological contactor. The invention has the advantages of easy processing, low cost, high efficiency of treatment, not easy to produce niff and easy installation and maintenance.

Description

Technical field [0001] The invention relates to the improvement of a biological turntable for sewage treatment. Background technique [0002] At present, the known biological turntable is composed of many discs or polygonal discs fixed on a shaft with small intervals, and the disc is the main body of the biological turntable. During the rotation of the biological turntable, the biofilm on the surface of the disk submerged in the sewage adsorbs the organic matter in the sewage; when the disk leaves the liquid surface and is exposed to the air, the biofilm on the disk absorbs oxygen from the air to absorb the organic matter. Oxidation to purify sewage. [0003] The biological turntable has the advantages of simple structure, safe operation, low power consumption, strong impact load resistance, and no clogging. It has been widely used in domestic sewage and industrial wastewater treatment in many industries, and achieved good results. But the biological turntable also has the...
