Pond differential niche ecological water treatment facility

Abstract

A pond differential niche ecological water treatment facility is characterized in that a T-shaped water partition wall is arranged in a long strip-shaped aquiculture pond along the length direction to divide the cultivation pond into an eating fish aquiculture zone and a filter feeding fish aquiculture zone; the two zones are communicated by a fishing gate, a water inlet gate, a sewage colleting pipe and an aeration pipe; a conical sewage collecting pit is arranged at the pond bottom of one end, close to the fishing gate, of the eating fish aquiculture zone as an eating and defecting zone for fishes. Fishes of different niches in the pond are cultured in a separating mode, feces and residual baits of the eating fishes are concentrated and input to the filter feeding fish aquiculture zone by pneumatic water flows, and are re-eaten, purified, disintegrated or adsorbed by algae in the filter feeding fish aquiculture zone, thus ensuring the good water quality of the eating fish aquiculture zone, facilitating the growth of eating fishes, culturing the filter feeding fishes with the feces and residual baits of the eating fishes, improving the ecological effect of the pond aquiculture and reducing culture pollution.

Description

technical field [0001] The invention relates to the field of pond culture, in particular to the pollution control and reuse technology of pond culture. Background technique [0002] my country is the country with the largest pond farming scale in the world. Due to the low level of industrial development, the technical level of related facilities, water quality regulation, and pollution control is not high. After the 1970s, large-scale pond reconstruction and construction were carried out, which increased the production of aquaculture and promoted the development of the pond aquaculture industry. However, there are still problems such as low degree of facilities for pond aquaculture, serious aquaculture pollution, and low conversion efficiency of aquaculture materials. Problems have seriously restricted the development of pond aquaculture. [0003] Since the 1980s, some domestic researchers have proposed construction methods for pond facilities, but little progress has been ...

AI Technical Summary

Problems solved by technology

[0005] First, the structure of traditional aquaculture ponds is simple, and the ecological efficiency of aquaculture is not high;

[0006] Second, although the traditional pond polyculture method can make full use of different ecological niches in the water body, there are problems such as the mutual influence of different fishes with different emergencies and the inconvenience of fishing;

[0007] Third, traditional ponds have problems such as difficulty in regulating the environment of aquaculture water;

[0008] Fourth, in traditional pond culture, fish excrement and fecal residual bait are mainly deposited on the bottom of the pond, causing problems such as deterioration of the breeding environment and serious sediment pollution.
