Embodiment 1

[0034] Such as figure 1 , figure 2 As shown, an enhanced nitrogen and phosphorus removal and resource reuse type constructed wetland system, including a constructed wetland pool 7, a water distribution system 1, an aeration system 2, a ventilation observation well 4, and a nitrogen and phosphorus removal substrate located in the constructed wetland pool And a liquid level control system 6; wetland plants 3 are planted in the nitrogen and phosphorus removal substrate.

[0035] The nitrogen and phosphorus removal matrix includes upper, middle and lower layers, and the height of each filler layer is 20 cm. The upper layer of the denitrification and phosphorus removal matrix is ​​the insulation layer 5.1, and the insulation layer is ceramsite with a particle size between 8 and 32 mm. The middle layer is the natural filler layer, and the lower layer is the construction waste mixed filler layer. Described natural filler layer comprises the first natural filler layer 5.2 of upper...

Abstract

The invention discloses an enhanced nitrogen and phosphorus removal and resource recycling type constructed wetland system. The constructed wetland system comprises a constructed wetland pool, a water distribution system, an aeration system, a ventilation observation well, a nitrogen and phosphorus removal matrix located in the constructed wetland pool and a liquid level control system, wherein wetland plants are planted in the nitrogen and phosphorus removal matrix. The constructed wetland system provided by the invention has the characteristics of high water quality purification capacity, low capital construction cost, convenience in operation and maintenance, good landscape effect and the like, and can meet the requirements of garbage recycling and resource saving.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an enhanced nitrogen and phosphorus removal and resource reuse type constructed wetland system. Background technique [0002] Constructed wetland has the characteristics of strong water purification ability, low infrastructure cost, convenient operation and maintenance, and good landscape effect. Therefore, it has been widely used in rural domestic sewage treatment, agricultural non-point source sewage prevention and control, tail water advanced treatment, and river micro-polluted water restoration. application. As a complete ecosystem, constructed wetland is mainly composed of substrate, plants and microorganisms. Among them, the substrate serves to purify water, provide growth carriers and nutrients for plants, provide attachment surfaces for microorganisms, and provide good hydraulic conductivity for water flow. It is not only the link between plants and microorganis...
