Embodiment 1

[0036] Please refer to figure 1 and figure 2 As shown, a sedimentation device, in this embodiment, the sedimentation device includes a sedimentation hopper 1, the side wall of the sedimentation hopper 1 is provided with a sludge inlet structure 2, and the sludge inlet structure 2 forms a mud-water mixture that enters the interior of the sedimentation hopper 1 The mud-water mixture enters the sedimentation hopper 1 through the sludge liquid inlet structure 2 for sedimentation and forms clear liquid and sedimentation sludge.

[0037] Among them, as an improvement to the sludge inlet structure 2, such as figure 1 and figure 2 As shown, the sludge inlet structure 2 includes a sludge inlet 201, which is provided on the side wall of the sedimentation hopper 1, and the sludge inlet 201 is used to introduce the mud-water mixture into the sedimentation hopper 1 through the sludge inlet 201. In this embodiment, the sludge inlet 201 is arranged on the side wall of the sludge settlin...

Embodiment 2

[0043] Please refer to figure 1 and figure 2 As shown, a settling device, in this embodiment, the settling device includes a settling hopper 1, the side wall of the settling hopper 1 is provided with a sludge liquid inlet structure 2, and the mud-water mixture in the pool body sedimentation area passes through the sludge liquid inlet structure 2 into the settling hopper 1 for sedimentation, and the mud-water mixture settles to form clear liquid and sedimentation sludge.

[0044] Wherein, as an improvement to the sedimentation bucket 1, such as figure 1 and figure 2 As shown, the settling hopper 1 includes a mud-water separation chamber 101 , and a sludge settling chamber 102 communicating with the mud-water separation chamber 101 is provided at the lower part of the mud-water separation chamber 101 . The sludge settling chamber 102 is a prism structure with a large top and a small bottom, and the sludge liquid inlet structure 2 is arranged on the side wall of the prism st...

Embodiment 3

[0058] The present invention also provides an application of a settling device. One, two, three, ... several settling devices are installed side by side in the settling process of a sewage treatment system (such as a physical sewage treatment system or a biochemical sewage treatment system). In zone 4, connect the liquid discharge port at the upper end of the sedimentation bucket 1 to the clear liquid treatment equipment; connect the sludge return pipe 3 of the sedimentation device to the sludge return device, and part of the settled sludge will be transported back to the anaerobic tank through the sludge return device. In the pool or anoxic pool, another part of the settled sludge is transported to the sludge treatment equipment for treatment.

[0059] In this example, if image 3 As shown, there are two sedimentation devices in the biochemical sewage treatment system. , when the sedimentation device is applied in the sewage treatment system, the sedimentation bucket 1 is lo...

Abstract

The invention provides a sedimentation device and application thereof. The sedimentation device comprises a sedimentation bucket composed of a mud-water separation chamber and a sludge settling chamber. A sludge liquid inlet structure is formed in the side wall of the sedimentation bucket, the sludge-water mixture enters the sedimentation bucket through the sludge liquid inlet structure to be settled, and the sludge-water mixture is settled to form clear liquid and precipitated sludge. The upper end of the sedimentation bucket is higher than the liquid level of the sludge-water mixture in thesedimentation area of the tank body; and the sludge liquid inlet structure is positioned below the liquid level of the sludge-water mixture. The sedimentation device further comprises a sludge returnpipe, wherein one end of the sludge return pipe extends into the sedimentation bucket from the lower part of the sludge settling chamber, and the other end of the sludge return pipe is connected witha sludge return device; and the sludge flows back to each process output point through the sludge return pipe by utilizing the sludge return device after the sludge-water mixture is settled and separated. The sedimentation device has the advantages of being simple in structure, low in cost, good in sedimentation effect, free of mud accumulation at the bottom and high in automation degree.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment and relates to sewage treatment system technology, in particular to a sedimentation device and its application. Background technique [0002] With the rapid development of science and technology and industrial technology, domestic sewage and production sewage are increasing, and the amount of sewage discharge is increasing. Direct discharge of sewage will pollute groundwater sources and the surrounding environment, reduce the amount of available water resources, and affect human health. Therefore, the national environmental protection department requires that production sewage and domestic sewage be treated up to standard before they can be discharged. [0003] At present, there are many kinds of sewage treatment systems and methods. The convenience of sewage treatment currently includes physical methods, biological methods, and chemical methods. Among them, the activated sludge ...
