Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0016] Such as figure 1 As shown, the flow of the artificial wetland sewage (waste) water treatment system is that the sewage enters the pressure regulating inspection well 2 through the main water inlet pipe 1, and part of it enters the subsequent hydrolysis pool 3 and artificial wetland 4 through the pressure regulating inspection well for biochemical treatment and then undergoes final treatment. The outlet pipe 5 is discharged; a part of the overflow flows out of the pressure regulating inspection well 2, and the water level of the subsequent hydrolysis tank 3 and constructed wetland 4 does not exceed the design water level to ensure the stable operation of the ecological treatment system.

[0017] Such as figure 2 , 3 , shown in 4: a pressure regulating inspection well for stabilizing the water intake of constructed wetlands. Water pipe 21, w...

Abstract

The invention discloses a pressure regulation manhole used for stabilizing constructed wetland inlet water. The pressure regulation manhole comprises a pressure regulation manhole body. The pressure regulation manhole also comprises a water inlet pipe, a water outlet pipe and an overflow apparatus connected on the wall of the pressure regulation manhole body. The water outlet pipe is positioned at the middle of the pressure regulation manhole body. The water inlet pipe and the overflow apparatus are positioned on the upper part of the pressure regulation manhole body. The overflow apparatus is arranged above the water inlet pipe. The water inlet pipe is provided with a flow guiding device. The water outlet pipe is connected to a hydrolysis tank and the constructed wetland. The manhole provided by the invention serves as an important component in a constructed wetland treatment process. The manhole can be used for stabilizing inlet water flow rate, and for preventing the impact towards the treatment system. Also, the manhole has a certain suspending solid separation effect. Therefore, the manhole is suitable for domestic sewage pretreatment in different areas, and is especially suitable for distributed and small-scale domestic sewage treatment projects of small towns and rural areas.

Description

technical field [0001] The invention relates to a pressure-regulating inspection well for stabilizing artificial wetland water intake, which is mainly used for adjusting and controlling the intake water level of a small-scale and decentralized artificial wetland sewage (waste) water treatment system, and belongs to the field of sewage (waste) water treatment. technology field. Background technique [0002] At present, the treatment of decentralized and small-scale sewage (wastewater) at home and abroad is mainly based on biological treatment processes (such as constructed wetlands, etc.), especially the treatment of vast rural sewage is mainly based on small-scale constructed wetlands. In view of the instability of rural sewage water, especially emergencies such as summer floods, it is easy to submerge the constructed wetland, which will cause the constructed wetland to fail to operate according to the normal load, and may cause the constructed wetland to be washed away in s...
