Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like figure 1 As shown, in this composite constructed wetland system, sewage enters the pressure regulating inspection well 1 through the main water inlet pipe, and further enters the subsequent high-load hydrolysis tank 2, natural reoxygenation / sedimentation integrated device 3 and constructed wetland 4 for multi-stage treatment Then it is discharged through the main outlet pipe.

[0028] like figure 2 As shown, the pressure regulating inspection well 1 includes a pressure regulating inspection well body 10, and the well wall of the pressure regulating inspection well body 10 is provided with a water inlet pipe 11, a water outlet pipe 12, and an overflow pipe 13, and the water outlet pipe 12 Located in the middle of the well body 10 of the pressure regulating inspection well, the water inlet pipe 11 and the overflow pipe 13 are locat...

Abstract

The invention discloses a composite constructed wetland system for sewage (waste water) treatment and ecological restoration. The composite constructed wetland system comprises four parts including a pressure regulating inspection well, a high-load hydrolysis tank, a natural reaeration / sedimentation integrated device and a constructed wetland, and the constructed wetland further comprises a constructed wetland body, an anti-blocking inlet water distributor, a strengthened dephosphorization denitrification groove, an outlet water collector and the like. The pressure regulating inspection well is located at the most front end of the system, sewage sequentially passes through the pressure regulating inspection well, the high-load hydrolysis tank and the natural reaeration / sedimentation integrated device to enter the constructed wetland, inlet water is distributed through the anti-blocking inlet water distributor, and the water is collected and discharged through the outlet water collector after being subjected to treatment of the constructed wetland body and the strengthened dephosphorization denitrification groove. The composite constructed wetland system is mainly used for urban sewage treatment, deep purification of initial stage rainwater and industrial tail water and the ecological restoration of polluted ground water bodies such as rivers and lakes.

Description

technical field [0001] The invention relates to a composite artificial wetland system for sewage (waste) water treatment and ecological restoration, mainly used for urban sewage treatment, deep purification of initial rainwater and industrial tail water, and ecological restoration of surface water bodies such as polluted rivers and lakes , belongs to the technical field of sewage (waste) water treatment. Background technique [0002] Constructed wetland is an ecological sewage treatment technology developed in the 1970s. Due to its characteristics of low investment, low operating cost, simple operation, and stable treatment effect, it has been widely used in various sewage (waste) water treatment fields. more widely used. However, since the artificial wetland is derived from simulating the natural ecology, it still has some natural and extensive characteristics, especially easy to block, the lack of dissolved oxygen affects the nitrification and denitrification effect, and ...
