Embodiment 1

[0030] A method for removing antibiotic resistance genes in an aquaculture environment, comprising the steps of:

[0031] (1) Construction of ecological floating bed plant system

[0032] Two groups of grass carp, silver carp, crucian carp and carp were mixed in the test pond. The area of ​​the aquaculture pond was 1 mu and the water depth was 3m. The breeding density of the aquaculture pond is: grass carp is 400 / mu, and the stocking size is about 200g / tail; silver carp is 200 / mu, and the stocking size is about 200g / tail; The specification is about 150g / tail. The management measures are the same, one group of fish ponds does not do any treatment, and one group of fish ponds builds ecological floating bed plants. The ecological floating bed accounts for 10% of the area of ​​the fish pond. The test plant of the ecological floating bed is water spinach. The ecological floating bed adopts degradable polystyrene foam board (300cm×100cm×10cm). For the planting holes, 2 to 3 water...

Abstract

The invention provides a method and a system for removing antibiotic resistance genes in an aquaculture environment. The method comprises the following steps: (1) constructing an ecological floating bed in an aquaculture pond: the ecological floating bed is arranged in the aquaculture pond with aquatic organisms and aquatic plants are planted on the ecological floating bed; (2) constructing a vertical flow artificial wetland and a water circulation system of the vertical flow artificial wetland: the upper layer of the vertical flow artificial wetland is a soil layer, the lower layer thereof is a gravel layer, wetland plants are planted in the soil layer, water in the aquaculture pond successively flows through the soil layer and the gravel layer, and then reflows to the aquaculture pond to form the water circulation system after entering the vertical flow artificial wetland. The method and the system for removing the antibiotic resistance genes in the aquaculture environment can effectively lower COD (Chemical Oxygen Demand) and the content of ammonia nitrogen in the aquaculture environment, and further can effectively control spreading of the antibiotic resistance genes in the environment to effectively reduce harm of the antibiotic resistance genes in the aquaculture environment on human health and provide scientific and reliable technical support for human health and environmental protection.

Description

technical field [0001] The invention relates to water purification technology in aquaculture environment, in particular to a method and system for removing antibiotic resistance genes in aquaculture environment. Background technique [0002] my country is the world's largest aquaculture country, accounting for about 70% of the world's total aquaculture production. However, due to the intensive development of aquaculture in recent years, the pollution has intensified, the quality of the aquaculture environment has continued to deteriorate, and the types of pathogenic organisms have increased and the speed of transmission has accelerated. At present, the main method of disease prevention and control is to use antibiotics. In addition to preventing and treating diseases, antibiotics also have the functions of promoting plant growth and saving nutrients. However, due to the lack of corresponding rules and regulations on the type and quantity of antibiotics used in the aquacultu...
