Example Embodiment

[0047] Example 1:

[0048] Such as figure 1 As shown, this embodiment provides a constructed wetland system, which mainly includes a water intake pretreatment system and a wetland ecosystem. The wetland ecosystem includes vegetation layer 1, sandy soil layer 2, and microbial immobilization layer 3 from top to bottom. , Mix the filter material layer 4 and the gravel layer 5.

[0049] A water inlet pipe 6 is arranged between the vegetation layer 1 and the sand layer 2 and a water outlet pipe 7 is arranged at the bottom of the gravel layer 5, and a plurality of drainage holes are arranged on the water inlet pipe.

[0050] The vegetation layer 1 is planted with emergent plants and floating-leaf plants, wherein the emergent plants are Zailiflower, Canna, and Barracuda, and the floating-leaved plants are Manchurian red.

[0051] The grain size of the sand in the sand layer 1 is 5 mm, and the thickness of the sand layer 1 is 23 cm.

[0052] The microbial immobilization layer 3 is prepared by...

Abstract

The invention provides a water-supplementing filtering type constructed wetland system and a treatment method thereof. The water-supplementing filtering type constructed wetland system mainly comprises a water feeding pretreatment system and a wetland ecological system, wherein the wetland ecological system comprises a vegetable layer, a sandy soil layer, a microorganism fixing layer, a mixed filtering material layer and a gravel layer in sequence from top to bottom. The water-supplementing filtering type constructed wetland system and the treatment method provided by the invention have the advantages that by the constructed wetland system, collected rainwater and water sources to be recycled and with worse water quality are purified and filtered, so that the discharged water can reach recycling standard; and simultaneously, the effects of purification, safety, landscape and benefit of the constructed wetland are considered.

Description

technical field [0001] The invention belongs to the technical field of resources and environment, and relates to a constructed wetland system and a processing method thereof, in particular to a water replenishing and filtering type constructed wetland system and a processing method thereof. Background technique [0002] In recent years, with the rapid development of urban construction, urban gardens and green spaces have decreased sharply, and the increase of impermeable ground has destroyed the natural hydrological and ecological balance, and various water ecological problems have emerged, mainly manifested in the deterioration of the water quality of urban inner lakes and the deterioration of rainwater resources. Loss, frequent urban floods, soil water source isolation and serious pollution of rainwater runoff, etc. How to scientifically and effectively manage urban landscape ecology, especially the construction of water ecological civilization and sponge city, has become ...
