Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

The invention discloses a settling pond for rural sewage treatment. The settling pond comprises a hollow tank body, a sludge collection hopper as well as a bracket, a sludge backflow pump and a pipeline, wherein the sludge collection hopper is mounted in the hollow tank body; the bracket is filled with a denitrification filler to form a denitrification area; the bracket is positioned inside the sludge collection hopper and above the sludge collection hopper; a settling area is formed in the sludge collection hopper; the denitrification area is positioned above the settling area; the sludge backflow pump is mounted at the bottom of the sludge collection hopper; and the pipeline communicates with the sludge backflow pump and is used for pumping out sludge settled in the settling area. As thebracket of the settling pond for rural sewage treatment is filled with the denitrification filler to form the denitrification area, deep denitrification can be implemented; as the settling area is formed in the sludge collection hopper to implement settling, and the denitrification area is positioned above the settling area, the space of the settling pond can be sufficiently utilized, the floor space of the settling pond can be reduced, the settling effect can be additionally improved, the total nitrogen removal rate can be increased, and the cost can be lowered.
Description
technical field [0001] The invention relates to sewage treatment, in particular to a sedimentation tank for rural sewage treatment. Background technique [0002] In the field of rural sewage treatment, in order to make the suspended solids meet the target requirements, it is necessary to set up a sedimentation tank to remove the suspended solids. The commonly used sedimentation tank is a simple tank with a mud bucket at the bottom, and the upper sedimentation area has a large space. In addition, in order to achieve a higher level of denitrification effect, deep denitrification is required. The addition of deep denitrification tanks and sedimentation tanks after biochemical treatment greatly increases equipment costs and floor space. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a sedimentation tank with small footprint, low cost, good sedimentation effect and deep denitrificatio...
