Series multi-step landscape type pond culture integrated system

Abstract

The invention belongs to the technical field of ecological agriculture, and discloses a series multi-step landscape type pond culture integrated system. The integrated system comprises aquaculture ponds, an ecological ditch and a tail water purification pond, wherein the culture ponds are connected through pipelines; the culture ponds and the tail water purification pond are in gradient distribution; filter dams are arranged between the culture ponds and between the culture ponds and the tail water purification pond; a brush filter tank and a ceramsite nitrification tank are arranged on each filter dam, and the ecological ditch is located on one side of the culture ponds and connected with the brush filter tanks; the tail water purification pond comprises a settling zone, an aeration zone, a constructed wetland restoration zone and a water collecting zone which are connected in sequence; the settling zone is connected with the ecological ditch, and the culture water passing through the filter dams and the settling zone respectively flow into the aeration zone; then the culture water sequentially flows into the constructed wetland restoration zone and the water collecting zone, purified water in the water collecting zone flows back to the culture ponds through a water pump, and water recycling is completed; and the settling zone is connected with a sewage collecting well, so that comprehensive utilization of culture water is realized.

Description

technical field [0001] The invention belongs to the technical field of ecological agriculture, and more specifically relates to a series multi-level landscape pond culture comprehensive system. Background technique [0002] With the improvement of living standards, the public's demand for aquatic protein and quality requirements are getting higher and higher. High-density and intensive aquaculture is increasingly favored by many farmers because it can produce higher yield and quality aquatic products with the same aquaculture area, and has become an important mode in current aquaculture. However, high-density aquaculture means higher water load, water quality deterioration leads to frequent disease occurrence, and the discharge of aquaculture tail water is not up to standard. The invention provides an internal circulation ecological aquaculture system that uses comprehensive measures such as slope topography and artificial wetlands to realize low-energy consumption series w...
