Embodiment Construction

[0022] Such as figure 1 , 3 As shown, the composite constructed wetland system includes surface flow constructed wetland unit 1 and vertical subsurface flow constructed wetland unit 2.

[0023] The surface flow constructed wetland unit 1 includes a pool body, an aeration pipe 4, a flow partition 5, a planting foam board 6, aquatic plants, and biological rope fillers. The pool body is made of pebbles, and the surface is fixed by barbed wire. The pool body is provided with a groove that is wide at the top and narrow at the bottom; one side of the pool body is provided with a water inlet 9, and the other side is provided with a water outlet 10. The water outlet 10 is provided with a filter grid for intercepting large volume of solid debris. One end of the aeration pipeline 4 is located outside the pool body, and the other end is buried inside the pool body. An air pump is arranged outside the pool body. The air outlet of the air pump communicates with the aeration pipeline 4; ...

Abstract

The invention discloses a composite constructed wetland system, which comprises a surface flow constructed wetland unit and a vertical underflow constructed wetland unit. The surface flow constructedwetland unit comprises a pool body, an aeration pipeline, a flow separation plate, a planting foam plate, aquatic plants and a biological rope filler. The vertical underflow constructed wetland unit comprises a planting layer, a first-stage filler layer, a second-stage filler layer, a third-stage filler layer and a pebble layer. The composite constructed wetland system is composed of the surface flow constructed wetland unit and the vertical underflow constructed wetland unit, can effectively solve the problem that the wetland is easy to block in the operation process, and meanwhile, improvesthe purification capacity of the whole wetland system on high-load sewage.

Description

technical field [0001] The invention relates to a compound constructed wetland system and its operation method. Background technique [0002] Constructed wetland technology is a process that can be used to treat sewage constructed by simulating the physical, chemical and biological effects of natural wetland ecosystems by artificially configuring substrates, plants and microorganisms. It has been widely used in small-scale sewage treatment due to its long service life, low operating cost and considerable treatment efficiency. Because constructed wetlands are prone to clogging during operation, the resulting reduction in treatment efficiency and easy impact on the surrounding environmental sanitation limit their further promotion and application. [0003] The clogging of constructed wetlands can be divided into three types: physical clogging, chemical clogging and biological clogging. Among them, the physical clogging is caused by the adsorption of inorganic or organic part...
