Embodiment 1

[0035] Example 1: (upflow bio-sedimentation filtration system configuration)

[0036] Such as figure 1 and figure 2 As shown, the present embodiment includes a trapezoidal trough, which is excavated below the ground, and is covered with impermeable film or other water-stopping materials 6 around and at the bottom. The tank body is filled with five parts, which are sand layer 1, sludge layer 2, mud-water separation layer 3, gas-collecting layer 4 and soil layer 5 from bottom to top. The backwashing air diffusion pipes 10 and 11 are laid in the sludge layer, the water distribution pipe 7 is laid in the bottom of the mud-water separation layer, and the water collection pipe 8 is laid in the middle and upper part of the mud-water separation layer. Wherein, the water distribution pipe 7 is located at the upper part of the air diffusion pipe, and the upper part of the water collection pipe 8 is close to the gas-collecting layer 4, and the pipe walls of the water distribution pi...

Embodiment 2

[0040] Example 2: (downflow bio-sedimentation filtration system configuration)

[0041] Such as image 3 and Figure 4 As shown, the structure of the functional area, backwash system and exhaust system of the downflow and upflow bio-sedimentation filtration systems are the same, the difference lies in the way of water inlet and outlet. Such as Figure 4 As shown, in the downflow biological sedimentation filtration system, the water distribution pipe 7 is horizontally arranged on the upper part of the mud-water separation layer, and the water collection pipe 8 is arranged at the bottom of the mud-water separation layer. The muddy water treated in the previous stage enters the sewage land bio-sedimentation filtration system for muddy-water separation through the water inlet pipe 13 through the perforated water distribution pipe 7 horizontally arranged in the mud-water separation layer 3 . The muddy water flows through the muddy-water separation layer 3 (composed of crushed ...

Embodiment 3

[0042] Embodiment 3: (direct advection biological sedimentation filtration system configuration)

[0043] Such as Figure 5 and Figure 6 As shown, the structure of the functional area, backwash system, exhaust system and water outlet method of the direct advection and upflow bio-sedimentation filtration systems are the same, and the only difference lies in the water inlet method used. The direct advection biological filtration sedimentation system does not need to set up water inlet pipes and water distribution pipes. The flow velocity distribution on the cross section of the biological filtration sedimentation system is roughly uniform. It is mainly suitable for occasions where the front-stage treatment method of sewage is the land biological treatment system. Such as Figure 6 As shown, the sewage land treatment system (such as Chinese patent CN 102001743 B) and the sewage land biological filtration sedimentation system for mud-water separation are built in the same tra...

Abstract

The present invention discloses a biological sedimentation filtering system for sewage land for separation of mud, including a groove body dug under the ground.: The sand layer, the sludge layer, the mud water separation layer, the gas collection layer, and the soil layer; there is a transitional layer between the mud layer and the mud water separation layer, the mud water separation layer and the gas collection layer;The soil layer is separated by mesh -shaped material; the water collection pipe is distributed in the middle and upper part of the mud water separation layer, and the water collection pipes are eventually connected to the drainage pipe; there are multiple trachea distributed in the gas pipe layer.The soil layer is connected to the atmosphere and extended above the ground.The present invention combines filtering and precipitation separation technology, the effect of sedimentation and separation of solid suspension is good, and the standard of water output is improved.At the same time, the separation layer of mud and the sludge layer is built under the land, reducing land occupation.

Description

technical field [0001] The invention relates to a sewage land bio-sedimentation filtration system for mud-water separation, and belongs to the technical field of sewage ecological treatment. Background technique [0002] At present, the commonly used solid-liquid separation methods in the sewage treatment process mainly include sedimentation and filtration. The method generally used for solid-liquid separation in sewage treatment is mainly precipitation. Sedimentation is a natural sedimentation separation method using gravity. [0003] The sedimentation tank is an important basic structure in the sewage treatment process based on the principle of sedimentation, and is mainly used to remove suspended solids. The sedimentation tank process is simple and effective, and it is an energy-saving mud-water separation method. However, the function of the traditional sedimentation tank is relatively single, only has the function of sedimentation and separation, and there are large ...
