Fresh water scale pond ecological breeding system

Abstract

The invention discloses a fresh water scale pond ecological breeding system. The system comprises five parts, namely a breeding pond, a pond water normal-position distributed treatment part, a pond discharge water abnormal-position centralized treatment part, a backwater function recovery treatment part and a pond water quality compensation treatment part. Breeding water aquatic ecology, pond breading and an aquaculture engineering technology are integrated organically; and pond microcirculation is formed through absorption, decomposition and nitrification functions of microorganisms, algae and the aquatic plants, particularly continuous removal of aquatic plants with growth and intermittent water supply, so that the utilization rate of pond eutrophic substances is improved, and breeding backwater is restored. The system has the remarkable effects of water saving and emission reduction and provides the high-efficiency pond ecological breeding system which is novel in process and is high in operability and economic and practical and has a unique structure for fishery industrialization and scale production.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a large-scale freshwater pond ecological cultivation system, which is characterized by aquaculture ponds, in-situ dispersed treatment of pond water, heterogeneous centralized treatment of pond discharge water, return water function recovery treatment and pond water quality compensation Processing consists of five parts. Background technique [0002] At present, my country is in the situation of saving resources and protecting the environment, and vigorously promotes the closed circulation pond culture method. Compared with the complex ecological system of natural rivers and lakes, the ecological environment of traditional pond culture is relatively fragile, lacks continuous self-purification ability, and can no longer meet the needs of social development. There are still many technical problems to be solved. [0003] In the traditional farming method, the feeding, metabolism ...

AI Technical Summary

Problems solved by technology

[0009] From the data analysis, the physical methods can be summarized as dredging, sedimentation, filtration and water exchange to achieve the purpose of improving the ecological environment of the water body. The disadvantage is at the expense of the external environment.

The chemical method is summarized as putting chemicals and oxidizing agents. The disadvantage is that while disinfecting and increasing oxygen, it also destroys the ecological balance and causes secondary pollution; the pharmacology is unknown, the dosage is unclear, and it will also cause drug residues or poisoning

The biological method is summarized as adding micro-ecological agents, such as microorganisms and algal agents. The disadvantage is that the smaller the water body, the easier it is to cause fluctuations in the physical, chemical and biological indicators of the pond.

The use of the three methods will generate certain operating costs and have an impact on the external environment. Therefore, closed breeding is imperative

[0010] The comprehensive method is mainly aimed at large-scale or large-scale ponds. The shortcomings are as follows: First, there is a serious imbalance between the input and output of the traditional pond culture method

With the growth of farmed animals and plants, the input materials continue to accumulate, and there is no effective method to continuously remove pond accumulations; second, for the entire pond ecosystem, it is difficult to meet the needs of regulation with one or two technologies alone, and there is a lack of existing methods. There are systematic combing and integration of technology and process flow, equipment matching and integration; third, the structure of the pond and the relationship between them, and the compensation for water supply are not reasonable. Disease occurs and affects the entire pond in series, making it difficult to prevent and control

At present, how to solve the above-mentioned problems in the large-scale freshwater pond ecosystem has not been reported in the literature
