Problems solved by technology

The system is composed of reservoirs, primary or secondary purification pools, and breeding pools. It adopts ectopic ecological restoration technical measures to alleviate the impact of aquaculture production on the external environment to a certain extent, but reduces Waste, the removal efficiency is limited after all
At the same time, because it is necessary to sacrifice part of the breeding area to purify the water quality, most farmers are unwilling to apply this technical model, causing most farmers to be unwilling to apply this technical model

Embodiment 1

[0043] Such as Figure 1-3 Shown, a kind of circulating water ecological farming community in a new type of pond, comprising:

[0044] Breeding area: used for aquaculture;

[0045] Ecological purification area: used to purify water for aquaculture, the ecological purification area includes primary utilization area, fruit and vegetable purification area, biological purification area and deep water area, and

[0046] Control area: used to monitor the water quality of the aquaculture water, the control area includes the office area and the management room set up near the aquaculture area;

[0047] The breeding area and the ecological purification area are arranged in such a way that the water flows in the form of a circular runway. The primary use area, deep water area, and biological purification area in the ecological purification area are arranged in sequence along the circular runway, and the fruit and vegetable purification area is arranged in the middle of the circular run...

Embodiment 2

[0061] The present invention provides another technical scheme on the basis of embodiment 1. This technical scheme adds the following scheme to the technical scheme of a kind of circulating flowing water ecological cultivation area in a new type of pond in embodiment 1: in the sedimentation tank, pass through the dividing plate with water hole 23 22 is divided into a primary sedimentation area and a secondary sedimentation area. The water hole 23 is arranged on the upper part of the partition 22, and the purified water is discharged from the outlet hole 21 arranged in the secondary sedimentation area. The purification is concentrated and discharged to the sewage collection unit. During the purification process, the height of the water hole 23 is used to make the purified water circulate from a high place, and the range of activities of microorganisms entering the sedimentation area is limited so that it is limited by the water flowing near the high water hole 23. Under the infl...

Embodiment 4

[0069] When the circulating flowing water ecological breeding quarter in a novel pond of the present invention was put into use: on the basis of Embodiment 3, the water pushing flow velocity in the setting breeding area was 0.2m / min, and fish farming was carried out in the breeding unit 14, and the fish The excrement and residual bait produced are collected by the sewage collection unit 12. After the water flows out of the sewage collection unit, it flows through the water chestnut area, the lotus area, the reed area, the artificial island and the deep water area, and then flows through the biological purification area. The aquaculture water is purified around the fruits and vegetables. The area flows like a runway, and finally returns to the water pushing unit 17. When the aquaculture water returns to the water pushing unit 17, the water quality is basically close to the source water, which fully meets the requirements for aquaculture water: pH is 6.5~8.5, NH 3 -N content belo...

Abstract

The invention discloses a new type of circulating water ecological breeding area in a pond. The breeding area: used for cultivating aquatic products; the ecological purification area: used for purifying the water for cultivation. The ecological purification area includes a primary utilization area, a fruit and vegetable purification area, a biological purification area and a deep water area. Area, and control area: used to monitor the quality of aquaculture water, the control area includes the office area and the management room set up near the aquaculture area; the aquaculture area and the ecological purification area are arranged in a layout that makes the water flow like a circular runway, and the ecological purification area The primary use area, deep water area, and biological purification area are laid out in sequence along the circular runway, and the fruit and vegetable purification area is arranged in the middle of the circular runway in a straight line. The invention also provides a new type of ecological breeding method for circulating water in a pond. The invention can realize the recycling of water resources, reduce the feed coefficient, and ecologically breed fish, aquatic plants, vegetables, etc., which is green, environmentally friendly, energy-saving and emission-reducing, and has high breeding benefits.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a novel pond internal circulating water ecological breeding plot and a novel pond internal circulating water ecological breeding method. Background technique [0002] At present, the average yield per mu of intensive culture ponds is more than 1000 kg, and there are not a few more than 1500 kg. The main means of maintaining such a high yield is the large-scale use of compound feed, large-scale water changes and the use of fishing machinery. Under normal circumstances, the bait coefficient is about 2.5, the water consumption per ton of fish is about 4,000 tons, and the power per mu is about 0.7 kilowatts. And 70-80% of the feed is discharged into the environment in the form of dissolved and particulate matter. According to the principle of energy transfer, that is to say, there are about 1,000 kg of N, P, and CO in each acre of breeding water. 2 and other organic...
