Description

Ecological toilet module for pond culture

Technical Field

The invention belongs to the field of aquaculture, and relates to an ecological toilet module for pond culture and an aquaculture pond containing the ecological toilet module.

Background

In many aquaculture modes in China, pond aquaculture is still the most important mode, statistics shows that the freshwater pond aquaculture area in 2015 in China reaches 270 million hectares and accounts for 43.94 percent of the total freshwater aquaculture area, and the total output and total output of pond aquaculture make important contributions to aquaculture. However, under the condition that the problems of frequent diseases, environmental pollution, water resource shortage, sudden increase of ecological environment pressure and the like are increasingly serious, the problems exposed by the traditional pond culture mode are also increasingly serious. According to incomplete statistics, the loss caused by aquaculture diseases in China is as large as hundreds of billions of yuan each year, the trend that the diseases are rapidly spread and the damage is more and more serious is presented, and the diseases become the biggest obstacle for the development of aquaculture industry in China.

Pond culture is generally an activity of performing culture in a relatively closed area, and the culture pond is a living place of culture objects, a decomposition place of excrement, residual bait and the like, and a culture pond of plankton. Thus, pathogenic bacteria can be rapidly spread, biological oxygen consumption and nitrogen and phosphorus element overload in the water body can be easily caused, eutrophication pollution of the water body is caused, and the virtuous cycle of an ecological system of the aquaculture water body and the healthy and sustained development of aquaculture are influenced. In the three-pond-in-one cultivation mode, various functions of the pond are mixed, and the positions of consumers, producers and decomposers in the pond are uncertain, so that the management difficulty is increased, and ecological imbalance is easily caused. Meanwhile, under the high-density pond culture mode, metabolites generated by the cultured objects cannot be separated and degraded in time, so that the water quality is more easily deteriorated. According to different culture varieties, in order to maintain the water body of the pond to meet the culture standard, the purposes of keeping water quality and cleaning excrement and residual bait are generally achieved by irregularly replacing a certain proportion of culture water body and cleaning pond bottom sediments every 3-5 years. However, the traditional method often discharges a large amount of untreated culture tail water into the environment, and causes great pressure on the surrounding ecological environment; in addition, a large amount of water resources are wasted, and labor is occupied. If sediments such as excrement, residual bait and the like in the pond cannot be cleaned in time, pathogenic bacteria can be rapidly spread, the culture water quality is unstable, and the health of a culture object is finally influenced. Therefore, excrement, residual bait and plankton corpses in the aquaculture pond can be timely and efficiently collected and timely discharged to become the key of pond aquaculture management, so that the healthy aquaculture water body can be favorably kept, and the wastes can be intensively treated and utilized. Therefore, the risk of disease occurrence can be reduced, the water changing amount and the water changing frequency can be reduced, the labor intensity of cultivation personnel can be reduced, the quality of aquatic products is finally improved, and the income of farmers is guaranteed. Meanwhile, aiming at the current situation of pond culture, the invention provides the modularized pond culture excrement and residual bait collecting and discharging device which is easy to modify, install and disassemble and has low cost and the matched pond modification scheme thereof.
