Example Embodiment

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Such as figure 1 As shown, the constructed wetland system includes a pool body 1 and a water inlet pipe 2. The pool body 1 is provided with a three-layer wetland filler for growing wetland plants 3, and the bottom of the pool body 1 is provided with a water outlet pipe 5 leading to a water outlet tank 4. A number of micro-sprinkler irrigation branch pipes 6 connected to the water inlet pipe 2 and equipped with sprinklers 13 are arranged above the pool body 1. The installation height of the micro-sprinkler irrigation branch pipes 6 is higher than the maximum growth height of the wetland plants 3, and the water inlet pipe 2 is provided There are a main water inlet valve 7, a booster pump 15, and a first timer 8. The first timer 8 is used to control the opening and closing of the main water inlet valve 7 and the booster pump 15. The outlet pipe 5 is provided with a ...

Abstract

The invention discloses a drying artificial wetland system and method capable of enhancing absorption of nitrogen and phosphorus. The system comprises a pool body and a water inlet main pipe, whereinthree layers of wetland filler for planting wetland plants are arranged in the pool body, a water outlet pipe leading to a water outlet trough is arranged at the bottom of the pool body, and a micro-spray branch irrigating pipe which is connected with the water inlet main pipe and provided with a nozzle is arranged above the pool body; and the set height of the micro-spray branch irrigating pipe is higher than the growth height of the wetland plants, the water inlet main pipe is provided with a water inlet main valve, a pressure pump and a first timer, and the water outlet pipe is provided with a water outlet main valve and a second timer. A mode of foliar-rhizome double cycled water distribution is adopted, the total nitrogen removal rate is 69.76%, the total phosphorus removal rate is 74.45%, and the removal rate of nitrogen and phosphorous is improved significantly when the method is compared with a traditional method of water distribution in roots; and through foliar spraying, thebiomass of the plants is also significantly higher than that of the traditional method.

Description

technical field [0001] The invention relates to a constructed wetland sewage treatment system and method, in particular to a dry-dry constructed wetland system and method for enhancing nitrogen and phosphorus absorption. Background technique [0002] As an engineered ecological treatment system, constructed wetlands strengthen natural processes through artificial design and transformation, retain wetland properties and purposefully treat sewage. The mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, and transformation. , plant shading, residue accumulation, transpiration water and nutrient absorption, and the role of various microorganisms. [0003] Constructed wetlands have low investment and operating costs for denitrification and dephosphorization, and are easy to manage, so they are favored in rural domestic sewage treatment projects. The removal of nitrogen in constructed wetlands is mainly through the ammonif...
