Embodiment 1

[0029] This embodiment provides a constructed wetland pool, such as Figure 1~3As shown, it includes a waterproof wetland pool bottom 34 and a waterproof wetland pool wall fixedly arranged on the waterproof wetland pool bottom 34. The waterproof wetland pool bottom 34 is a pool bottom covered with a waterproof layer, and the waterproof wetland pool wall is a pool covered with a waterproof layer. Wall; the waterproof wetland pool wall includes a pool wall 12 in a water-dividing area, pool walls 21 in two vegetation areas, and pool walls 18 in two water-distributing areas. It is an outwardly protruding arc-shaped pool wall, and two water dividing walls 24 are symmetrically arranged behind the water inlet 9 of the wetland pool near the water inlet 9 of the wetland pool, and one end of the two water dividing walls 24 is connected, and the two water dividing walls 24 The other end of the water divider is connected to the two ends of the pool wall 12 of the water divider respectivel...

Embodiment 2

[0038] This embodiment provides a composite sewage treatment system, such as Figure 4 As shown, it includes a grid grit chamber 2 and at least one composite constructed wetland treatment system, the grid grit chamber 2 is connected with a main water inlet pipe 1; the composite constructed wetland treatment system is connected in parallel to the grid grit chamber through the water inlet channel 3 On the water outlet of the pool 2, the outlets of each composite constructed wetland treatment system are connected to a main outlet pipe 8 through the water inlet channel 3; 4. The wetland treatment system and post-treatment pool 7. The wetland treatment system includes a subsurface wetland pool 5 and a surface flow wetland pool 6 connected by an inlet channel. The subsurface wetland pool 5 and the surface flow wetland pool 6 are not limited Sequentially, subsurface wetland 5 and surface flow wetland pool 6 are the constructed wetland pools in Embodiment 1, the vegetation area of ​​s...

Abstract

The invention discloses a constructed wetland tank; a waterproof wetland wall of the constructed wetland tank includes a division region tank wall that is an arc tank wall raised out, two water division walls are arranged in the rear of a wetland tank water inlet, the two water division walls are connected at one end, the other ends of the two water division walls are connected with a vegetation region tank wall, the vegetation region tank wall is connected with one end of one outflow region tank wall, the other ends of the outflow region tank walls are connected together, the joint of the two outflow region tank walls is provided with a wetland tank water outlet, an outflow wall is arranged in the front of the wetland tank water outlet, two ends of the outflow wall are connected to the tail ends of the vegetation region tank walls, and the outflow wall is provided with a plurality of homogenous flow outlets. A composite wastewater treatment system is also disclosed; the constructed wetland tank and the composite wastewater treatment system allow water flows to be uniformly distributed, water flow speed is decreased, water retention time is extended, wastewater purification time is longer, and pollutants are degraded more thoroughly.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an artificial wetland pool and a composite sewage treatment system. Background technique [0002] The distribution of water resources in my country is characterized by more in the south and less in the north. The per capita water resources in the northern region are less than 1 / 3 of the national average. The contradiction between the shortage of water resources and social and economic development and the protection of the ecological environment has become more and more prominent. It has become difficult to solve it only by saving water and tapping the potential of local water resources without guest water resources. As a major measure to solve the serious shortage of water resources in my country and even the world, pollution control and water purification are also the basic strategic national policies related to the sustainable development of my country's economy and soc...
