Embodiment Construction

[0029] Below in conjunction with embodiment the present invention will be further described.

[0030] The invention discloses a wetland system for purifying coastal aquaculture water bodies based on microbial immobilization technology and farmland irrigation technology, such as figure 1 As shown, including microbial agents, farmland wetland systems and aquaculture water bodies, by using microbial agents to hold feces, free nitrogen ions, feed residues, and microorganisms in aquaculture water bodies to form a large complex, and then relying on farmland wetland systems to achieve The interception of pollutant complexes realizes the purification of aquaculture water.

[0031] Specifically, during application, the microbial inoculation agent is firstly prepared.

[0032] The microbial bacterial agent is prepared by Bacillus amyloliquefaciens IAE, and the strain preservation number of Bacillus amyloliquefaciens IAE is CCTCC NO: M2013086. Inoculate Bacillus amyloliquefaciens IAE i...

Abstract

The invention discloses a wetland system for purifying a coastal aquaculture water body based on a microorganism immobilization technology and a farmland irrigation technology. The wetland system comprises microbial agent, a farmland wetland system and an aquaculture water body, wherein by utilizing adhesion functions of extracellular polypeptide and thalli of the microorganism, pollution substances such as a large quantity of excrement, feed residues and free-state nitrogen ions in the aquaculture water body are immobilized and concentrated; by adopting an irrigation way, a formed complex of thallus-metabolites-pollutants is effectively intercepted by using the farmland wetland system, and the interception efficiency of the pollutants can reach 93%. According to the system disclosed by the invention, the coastal aquaculture water body can be effectively treated, and the pollution to offshore ecological environment is reduced; meanwhile, water resources are provided for agriculture, and the system has a good application prospect.

Description

technical field [0001] The invention relates to a wetland system for purifying coastal aquaculture water based on microbial immobilization technology and farmland irrigation technology, belonging to the technical field of microorganisms. Background technique [0002] With the improvement of the quality of social material life, the demand for aquatic products in residents' diet is increasing year by year. Due to the abundance of land and less pollution in coastal areas, a large number of aquaculture industries are concentrated in coastal areas. Therefore, the annual water exchange in the aquaculture process produces a large amount of pollutants, which leads to the deterioration of the offshore water environment. [0003] In recent years, the country has included "ecological civilization construction" and "ecological red line protection" into the construction of social systems, and ecological environment protection into the comprehensive consideration of social and economic d...
