Embodiment 1

[0057] see Image 6 with 7 According to the actual sewage treatment capacity, select an appropriate number of tower units. When the reactor is specifically installed, the base cylinder 1 is fixed by the bracket leg 24 at the bottom, and then the multiple tower units and the clarifier cylinder are connected through the butt joint flange 6 5 are sequentially assembled on the base cylinder 1. During the docking process, the partitions 23 in adjacent tower units are arranged correspondingly to form an aerobic zone 9, anoxic zone 8 or good / deficient zones between adjacent tower units. The oxygen zone 7 is separated and connected independently by the partition plate 23 .

Embodiment 2

[0059] see Image 6 with 8 According to the actual sewage treatment capacity, select an appropriate number of tower units. When the reactor is specifically installed, the base cylinder 1 is fixed by the bracket leg 24 at the bottom, and then the multiple tower units and the clarifier cylinder are connected through the butt joint flange 6 5 are sequentially assembled on the base cylinder 1. During the docking process, the partitions 23 in adjacent tower units are arranged alternately to form an aerobic zone 9, anoxic zone 8 or good / deficient zones between adjacent tower units. The oxygen zone 7 is not separated by the partition 23, and the biological flora in each zone circulates with the sewage, thereby increasing the range of activities of the biological flora, which is beneficial to the improvement of the sewage treatment capacity.

Abstract

The invention discloses a split modular biological fluidization composite reactor for sewage treatment, and relates to the technical field of sewage treatment. The split modular biological fluidization composite reactor comprises a base cylinder, a plurality of tower units and a clarification cylinder, wherein the base cylinder, the tower units and the clarification cylinder are spliced into an integrated structure, the tower unit comprises an outer cylinder body, a middle cylinder body and an inner cylinder body, the middle cylinder body and the inner cylinder body are sequentially arranged in the outer cylinder body, a plurality of partition plates are arranged between the cylinder bodies in the tower unit, an aerobic / anoxic zone, an anoxic zone and an aerobic zone are arranged in each tower unit, a liquid inlet pipe is connected to the bottom of the inner sealing cylinder body in the base cylinder, an oxygen supply pipe is connected to the liquid inlet pipe, a plurality of aerationheads are arranged at the positions, corresponding to the aerobic zones, in the base cylinder, a water outlet is formed in one side of the clarification cylinder, and a mud discharge pipe is arrangedon one side of the bottom of the base cylinder. The tower body adopts a split modular design, so that the production difficulty and the construction difficulty are effectively reduced, the tower height setting is flexible, the structural strength is high, and the sewage treatment capacity is remarkably improved.

Description

technical field [0001] The invention belongs to sewage treatment technology, in particular to a split-type modular biological fluidization composite reactor for sewage treatment. Background technique [0002] my country is currently facing serious water pollution problems. With the increasingly stringent wastewater discharge standards, especially nitrogen and phosphorus discharge standards, there is an urgent need for urban sewage and industrial wastewater treatment technologies. Wastewater biological treatment uses various microorganisms in nature to degrade Organic matter in wastewater is an effective method for wastewater treatment. Biological treatment methods are divided into two categories: atrophic and anaerobic. Aerobic biological treatment has high efficiency and is widely used, and is the main method of biological treatment; anaerobic biological treatment uses facultative anaerobic bacteria and obligate anaerobic bacteria to degrade organic matter, and macromolecula...
