Problems solved by technology

Since the immersion ratio of the biological turntable is in the range of 30-45%, the driving device is immersed in the water and is affected by the resistance of the water. There are problems of high rotational resistance and low speed, which reduces the oxygenation efficiency and affects the sewage treatment efficiency of the biological turntable.

Embodiment Construction

[0021] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0022] Such as Figure 1~Figure 4 As shown, the combined drop water driven biological turntable reactor of the present invention includes a tank body 1 , a high-level water distribution tank 4 arranged above the tank body 1 , and a mud discharge pipe 5 arranged at the bottom of the tank body 1 . The pool body 1 is divided into a turntable area 2 and a driving area 3, separated by a partition 7 in the middle. The rotating shaft 6 traverses the turntable area 2 and the driving area 3, and is fixed on the side wall of the pool body 1. The mud discharge pipe 5 crosses the turntable area 2 and the driving area 3 and is placed at the bottom of the pool. The high-level water distribution tank 4 includes an outlet triangular weir 401 and a diversion dispersion plate 402, such as Figure 5 shown.

[0023] The turntable area 2 includes a turntable 201 , the t...

Abstract

The invention discloses a combined drop-driven biological rotating disk reactor which comprises a tank body (1), wherein the tank body (1) comprises a rotating disk region (2) and a drive region (3); a rotating disk (201) is arranged in the rotating disk region (2) through a rotating shaft (6); a drive disk (301) for driving the rotating disk (201) to rotate is arranged in the drive region (3); the liquid level of the drive region (3) is arranged below the drive disk (301); the bottom of the drive region (3) is provided with an auxiliary filler oxidation region (302) for degrading the sewage; and the front end of the auxiliary filler oxidation region (302) is provided with a water outlet tank (303) for controlling the liquid level of the drive region (3). By adopting the drive disk and rotating disk function division, the liquid level of the drive region is on the bottom of the drive disk, thereby eliminating the resistance of water to the drive unit, enhancing the rotation speed of the rotating disk, and obviously enhancing the oxygenation rate. The auxiliary oxidation filler region is utilized to reinforce the removal of organic substances in the sewage, thereby being beneficial to enhancing the nitrification properties of the reactor.

Description

technical field [0001] The invention belongs to the technical field of water pollution control, and relates to a small-scale decentralized domestic sewage treatment combined drop-water-driven biological turntable reactor in rural areas. Background technique [0002] At present, the distributed domestic sewage in rural areas has a small discharge volume, high pollutant concentration, and large dispersion. However, the rural sewage pipe network facilities are not perfect, and centralized treatment is difficult. The traditional urban sewage treatment process is applied in rural areas, which requires large investment, high operating costs and unstable results. Therefore, it is urgent to develop and apply to rural decentralized domestic sewage treatment facilities. [0003] As a kind of biofilm method, the biological turntable has the characteristics of large attached biomass, high degradation efficiency of organic matter, certain nitrification performance, strong impact load re...
