An ecological symbiosis system and application method of multi-stage surface flow constructed wetland based on pool ridge

Abstract

The invention discloses a multi-order surface flow artificial wetland symbiotic ecosystem based on a pond ridge and an application method. The symbiotic ecosystem comprises two adjacent cultivation ponds, wherein the pond ridge for isolating is arranged between the two cultivation ponds; a plurality of aquatic plant planting areas which are adjacent in sequence and decreasing in bottom surface heights in sequence are dug on the pond ridge to construct a multi-order surface flow artificial wetland. Cultivation water bodies of the cultivation ponds are pumped into the multi-order surface flow artificial wetland through a diving pump to form water body circulation of the cultivation ponds and the multi-order surface artificial wetland and construct the symbiotic ecosystem. The symbiotic ecosystem is novel in structure, the cultivation water quality can be purified ecologically, the safety of aquatic products is promoted, the land utilization rate is increased effectively, and land waste is avoided; meanwhile, the pond ridge is reutilized, so that the income of peasants can be increased, the aim of increasing both production and income is fulfilled, and the demand of the national development strategy is met.

Description

technical field [0001] The invention relates to a multi-stage surface flow artificial wetland ecological symbiosis system based on a pool ridge and a method for using it, and relates to fish breeding, aquatic plant planting, and lower aquatic animal stocking, etc., and belongs to aquatic animal breeding, aquatic vegetable planting and water ecological environment Restoration technical field. Background technique [0002] The key to restricting the development of intensive aquaculture is the water quality of the aquaculture water body, and the water quality management of the aquaculture water body is the focus of the farmers. At present, there are several methods to deal with the water quality of aquaculture water bodies: [0003] One is the physical method, that is, through mechanical algae removal, pumping out old water, adding new water, etc., but it often treats the symptoms but not the root cause, and is time-limited, so it can only be used as an emergency measure; [...

Problems solved by technology

[0003] One is the physical method, that is, through mechanical algae removal, pumping out old water, adding new water, etc., but it often treats the symptoms but not the root cause, and is time-limited, so it can only be used as an emergency measure;

[0004] The second is chemical methods, such as the use of chemicals to kill algae and bacteria, but it costs a lot and is easy to cause secondary pollution;

[0005] The third is microbial or plant methods, such as putting photosynthetic bacteria, Bacillus bitternii and other beneficial bacteria, or stocking algae-controlling organisms, or setting up biological floating beds, but because a complete ecological chain cannot be formed, or the water surface is occupied, the photosynthesis of the water body is affected. , cannot be maintained for a long time;

[0006] The fourth is to establish artificial wetlands, such as artificial wetlands built by excavating ring ditches around fish ponds, or specially using ponds to establish artificial wetlands, but the efficiency is low due to large land occupation or difficult management

Existing ponds (such as figure 1 shown), the ridge between the two ponds 1 is only used for isolation or walking, and the land resources cannot be rationally utilized
