Embodiment 1

[0023] One water distribution pool (1), the length: width: height of the water distribution pool is 300: 100: 80cm respectively; the storage pool (2) is one, the length: width: height of the water storage pool is 200: 200: 80cm respectively; the planting pool (3-14 ) twelve, each planting pool length: width: height is 600:100:80cm respectively. Each planting pool is divided into 3 parts evenly by partitions. Each part is filled with the same matrix, from bottom to top, gravel with a thickness of 15 cm and a particle size of 5 to 8 cm, and sand with a thickness of 25 cm and a particle size of 0.05 to 1 mm. The planting pools (3-14) and the partitions (15) are constructed of reinforced concrete, and an anti-seepage film layer is laid inside (including laying in the middle of the two pools and the bottom of the pool). Collect the rhizomes of cattail and reed in the wetland of Beijing Wildlife Rescue and Breeding Center, and select the rhizomes with robust growth and uniform size...

Abstract

The invention relates to a novel wetland phosphorus cycle simulation device and an operation method thereof. The device mainly comprises a service reservoir (1), a storage reservoir (2) and planting pools (3-14), wherein the service reservoir (1) is connected with the planting pools (3-14) through a pipeline; different wetland plants and combination thereof are planted in the planting pools (3-14). The sewage in the service reservoir (1) is pumped into the planting pools (3-14), and the cyclical characteristics of phosphorus in the wetland are studied by regularly monitoring the concentration of phosphorus in different forms in the planting pools. The device can be used for comprehensively studying the influence of inflow rate, water depth and vegetation type on the phosphorus cycle process so as to provide scientific basis for wetland restoration.

Description

technical field [0001] The invention relates to a novel wetland phosphorus cycle simulation device and an operation method thereof, which are suitable for studying the influence of wetland phosphorus cycle and external factors on the phosphorus cycle process. Background technique [0002] With the development of the economy, my country is facing increasingly serious water pollution problems. The discharge of a large amount of domestic sewage, industrial wastewater, and farmland water has led to a rapid increase in the concentration of pollutants in the water body, and serious eutrophication of the water body has caused huge economic losses and social impacts. . [0003] Wetlands have the functions of retention, removal and transformation of toxic and harmful substances. Wetlands can effectively reduce the concentration of pollutants in water bodies through processes such as absorption and enrichment by aquatic plants, sediment adsorption and deposition, and microbial assimil...
