Method for constructing pond culture circulating water system

Abstract

The present invention provides a method for constructing a pond culture circulating water system. The method comprises the following steps of constructing a culture system and circulating water. A culture system comprises a purification pond and a plurality of culture ponds, the purification pond is positioned in middle of the culture system, the plurality of the culture ponds are distributed on two opposite sides of the purification pond, and a water purification device, a first purification area and a second purification area are sequentially arranged in the purification pond from left to right; a backflow reservoir is arranged outside the culture system, circulating water pipelines are arranged on an outer periphery of the culture system in a surrounding mode, a water gate, a water inlet and a water outlet are arranged on the circulating water pipelines, the water inlet and the water outlet are respectively arranged on two sides of the water gate, a water inlet valve is arranged onthe water inlet, a water outlet valve is arranged on the water outlet, each culture pond communicates with the circulating water pipeline and the purification pond, and a water outlet branch pipe anda water inlet branch pipe on the same culture pond are oppositely arranged at a bottom part of each culture pond; and the purification pond communicates with the circulating water pipeline through a water drainage pipe, and a control valve is arranged on the water drainage pipe. The method is high in efficiency, low in investment, low in energy consumption, good in applicability and high in operability.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a construction method of a pond culture circulating water system. Background technique [0002] Artificial pond culture constructed of concrete is a common way to use ponds for high-density intensive culture. The water circulation method adopted in this method is stagnant. After a period of breeding, with the accumulation of excrement from the breeding objects and the corruption and deterioration of residual erbium caused by excessive feeding, the water quality in the pond will continue to deteriorate, and the bacterial content in the water will increase. Oxygen content drops, affecting the healthy growth of breeding objects. Therefore, replacing water in large quantities has become an important technical measure to improve the water quality of ponds. The direct discharge of pond wastewater will not only pollute the environment, but also waste water resources, which is not ...
