Embodiment 1
[0025] A domestic sewage treatment system, the sewage treatment system includes from left to right successively connected artificial grid 2 pools, sedimentation tank 7, primary treatment pool 19, secondary treatment pool 18, tertiary treatment pool 17, fourth Level treatment pool 16, horizontal subsurface flow constructed wetland 11, vertical subsurface flow constructed wetland 12 and outlet pool 13, the artificial grid 2 pools are connected with water inlet pipe 1, the outlet pool 13 is connected with outlet pipe 14, and the sedimentation tank 7 , first-level treatment pool 19, second-level treatment pool 18, third-level treatment pool 17, and fourth-level treatment pool 16 are provided with water outlet channel 5, and described sedimentation tank 7, first-level treatment pool 19, and second-level treatment pool 18 1, tertiary treatment pool 17 and the top of the fourth-level treatment pool 16 are all provided with a clearing mouth 15, and crushed straw 8 is placed in the sedi...
Embodiment 2
[0028] On the basis of Example 1, the artificial grid 2 is provided with a grid 2 and an oil separation net 3 sequentially from top to bottom. Larger floating objects, impurity particles and grease are removed by setting the grille 2 and the grease trap 3 in the artificial grille 2 pool.
Embodiment 3
[0030] On the basis of Example 1, a water barrier is provided below the outlet channel 5 in the sedimentation tank 7 . The splashing of sewage can be effectively controlled by setting the water baffle 6 , so that the flow of sewage entering the primary treatment tank 19 is more gentle.

Abstract
The invention discloses a domestic sewage treatment system, which comprises a manual grid pool, a sedimentation tank, a primary treatment tank, a secondary treatment tank, a tertiary treatment tank, afourth treatment tank, a horizontal subsurface constructed wetland, a vertical subsurface constructed wetland, and a discharge pool, the artificial grid pool is connected with an inlet pipe, and thedischarge pool is connected with an outlet pipe, and water outlet channels are arranged among the sedimentation tank, the primary treatment tank, the secondary treatment tank, the tertiary treatment tank, and the fourth treatment tank, the tops of the sedimentation tank, the primary treatment tank, the secondary treatment tank, the tertiary treatment tank and the fourth treatment tank are all provided with a clearing mouth, the sedimentation tank is provided with crushed straw, the primary treatment tank and the secondary treatment tank are all provided with an activated carbon adsorbent, andthe tertiary treatment tank and the fourth treatment tank are all provided with a biological filler. The domestic sewage treatment system has the advantages of fully automatic operation, simple process, no energy consumption, and high decontamination efficiency, and is suitable for the treatment of decentralized domestic sewage.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a domestic sewage treatment system. Background technique [0002] Water pollution will cause the degradation of the ecosystem and the reduction of biodiversity in rivers and lakes. Usually, urban sewage treatment plants treat industrial and urban domestic sewage as the treatment object, and the effluent water quality is the second-level standard. deal with. The main characteristics of rural sewage are: low concentration of sewage, good biochemical properties, scattered and difficult to collect. From the perspective of resource utilization, rural sewage belongs to sewage that can be treated and reused because of its high nitrogen and phosphorus content, which is another form of fertilizer. Therefore, rural sewage treatment should fully consider this water quality characteristic for treatment. [0003] At present, the technology of rural domestic sewage treatment is mat...
