Embodiment 1

[0017] Such as figure 1 with figure 2 As shown, a hydrodynamic biological turntable sewage treatment equipment of the present invention includes a sewage tank 1 , a biological turntable 2 and an upper cover 3 . The downstream end of the sewage tank 1 is provided with a water outlet 11 , the main structure of the biological turntable 2 is composed of a bracket 22 , and a filler 23 is installed inside, the biological turntable 2 is also provided with a bucket 21 , and the upper cover 3 is provided with a water inlet pipe 31 . The filler 23 can be a spherical filler or a composite filler.

[0018] The water flow enters the water bucket 21 through the water inlet pipe 31, and utilizes the gravity of the water accumulated in the water bucket 21 to push the biological turntable 2 to rotate.

[0019] The hydrodynamic biological turntable sewage treatment equipment of the present invention saves mechanical power equipment such as motors and reducers, has low operating costs, and is...

Embodiment 2

[0021] Such as image 3 with Figure 4 As shown, another hydrodynamic biological turntable sewage treatment equipment of the present invention includes a sewage tank 1 and a biological turntable 2 . The downstream end of the sewage tank 1 is provided with a water outlet 11, and the biological turntable 2 is composed of several biological filler disks 24, and a bucket 21 is also arranged on the biological turntable 2.

[0022] The water flow enters the water bucket 21 through the external water inlet system, and the gravity of the water accumulated in the water bucket 21 is used to push the biological turntable 2 to rotate.

Abstract

The invention relates to hydrodynamic biological rotating disc sewage treatment equipment, which comprises a sewage tank (1) and a biological rotating disc (2), wherein the downstream end of the sewage tank (1) is provided with a water outlet (11). The hydrodynamic biological rotating disc sewage treatment equipment is characterized in that water buckets (21) are arranged on the biological rotating disc (2); water flow enters each water bucket (21) through a water inlet system; the biological rotating disc (2) is pushed to rotate by utilizing the gravity of water accumulated and stored in the water buckets (21).

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to biological turntable sewage treatment equipment. Background technique [0002] The biological turntable is an efficient and economical sewage biological treatment equipment developed on the basis of the biological filter. The biological turntable is composed of a water tank and a rotating disc partially submerged in sewage. The microbial film grown on the surface of the disc repeatedly contacts the sewage in the tank and oxygen in the air to purify the sewage. [0003] The biological turntable process is a kind of biofilm sewage biological treatment technology. This treatment method makes microbes such as bacteria and fungi and protozoa grow and breed on the biological turntable filler carrier to form a film-like bioactive sludge. - biofilm. After primary treatment in the sedimentation tank, the sewage is in contact with the biofilm, and the microorganisms on the biofilm absorb the...
