Background
With the improvement and popularization of freshwater aquaculture technology, pond aquaculture in China increasingly adopts a fine aquaculture technology mode with high density and high bait casting rate. Because the intensive culture in ponds is mostly semi-closed water purification culture, feed, chemical residues and excrement of aquatic products added in the culture process are accumulated in water bodies for a long time, so that the wastewater contains a large amount of nitrogen, phosphorus and organic pollutants, and fish poisoning death and water eutrophication can be caused, and the culture water environment is deteriorated. Key factors influencing the degradation and purification effects of microorganisms on pollutants are the number of microorganisms, the type of flora, environmental conditions and the like. The traditional method for increasing the microorganism quantity is to directly inoculate microorganisms into the culture water body, but the microorganism is affected by the environmental conditions unsuitable for growth, is easy to run off along with the water body, and the treatment effect is often not ideal. The Microbial Immobilization (MIM) technology is a biological technology that uses physical or chemical means to confine or localize selected free microorganisms within a limited spatial area, so that they remain highly dense and highly bioactive. By MIM technology, biomass and concentration in the bioreactor are greatly improved, processing capacity is enhanced, the time for keeping activity of microorganisms is increased, and the microorganisms can be reused, so that pollutants in aquaculture wastewater can be removed more efficiently. However, when the concentration fluctuation of the pollutants in the cultivation wastewater is large and high, the condition that the quality of the effluent water exceeds the standard caused by untimely microorganism treatment often exists.
The ecological wetland is a novel artificial ecological engineering wastewater treatment technology by simulating a natural wetland mechanism, and the system can purify the cultivation sewage by utilizing the synergistic effect of physics, chemistry and biology, and has the advantages of more stable effect, small investment, low energy consumption and convenient operation management. Wherein the large plant is an essential component of the constructed wetland. The plant restoration is a green, environment-friendly, low-cost, energy-saving and economical sewage treatment technology, and the aim of efficiently removing pollutants is fulfilled by removing biomass of some plants, especially large plants, rhizome plants and the like. However, the ecological wetland technology has problems of low treatment efficiency and poor load impact resistance when the concentration of the influent pollutants is high.
