Facility system for regulating and controlling water quality of deep water aquaculture pond

Abstract

The invention relates to an improved system for regulating and controlling the water environment of a deep water aquaculture pond. In a facility system for regulating and controlling the water quality of the deep water aquaculture pond, the side part of the deep water aquaculture pond (1) with a water depth of over three meters is vertically provided with a draw well (3) with the same depth as the pond (1); the bottom of the pond (1) is communicated with the draw well (3) through an intake pipe (2); water conveying equipment (4) is arranged on the upper port of the draw well (3); the outlet of the water conveying equipment (4) is communicated with the upper layer of the pond (1) through a water return pipe (5); the water conveying equipment (4) can also be communicated with the upper layer of the pond (1) through a water body treating facility and the water return pipe (5); the water conveying equipment (4) is a low-lift axial-flow pump or an aeration water elevator; and the water treating facility (6) is an artificial wetland or an aeration biochemical filter chamber. The system can break the thermocline of the deep water pond, improves, regulates and controls the aquaculture environment of the pond and has the characteristics of energy conservation, emission reduction, cycle, simple structure, convenient construction, easy maintenance and high popularization and application values and social and economic benefits.

Description

technical field [0001] The invention relates to a system for improving the water environment of aquaculture ponds, in particular to a water quality control facility system for deep-water aquaculture ponds. Background technique [0002] Pond aquaculture is the main production mode of aquaculture in China and occupies an important position in my country's aquaculture industry. According to the 2007 "China Fishery Yearbook", in 2006, there were 2.531 million hectares of freshwater pond aquaculture in the country, and the aquaculture output was 14.95 million tons. The average national pond aquaculture output was only 394 kg / mu. The water depth of traditional aquaculture ponds in my country is generally about 1.5-2.5 meters. Increasing the water depth of ponds will increase the production of pond aquaculture. Under the situation of increasingly tight land resources in our country, it is of great practical significance to carry out deep-water pond aquaculture, which can be used wi...

Problems solved by technology

Deep-water ponds generally refer to ponds with a breeding water depth of more than 3 meters. In deep-water ponds, due to the deep water body, the upper and lower water bodies can easily form a water layer due to changes in water temperature, resulting in a lack of oxygen and poor water quality at the bottom of the pond. The equipment and facilities in the water layer of deep-water ponds have not been promoted and used nationwide for many years

At present, deep-water pond aquaculture has been used in southern and northern China. The methods used to improve pond water quality are mainly to increase water stirring power, bottom aeration and increase water exchange. It has a certain effect on regulating water quality, but it needs to consume a lot of electricity, and the effect of water quality regulation is not very stable.
