Nitrogen Removal Technology and Application in Facility Fish Farming Wastewater in Guiyang City
Abstract：In recent years, Guiyang City has conducted in-depth exploration and practice in the field of mountainous area characteristic fishery, developing various facility fish farming models. By utilizing idle mountain ponds and irrigation-type reservoirs to develop engineering circular water farming; transforming old ponds into high-position pools for farming; building modern farming workshops in idle factories and greenhouses, promoting factory-based farming; relying on barren mountains and slopes to develop land-based circular pool circular water farming; and using mountain spring water and reservoir bottom water resources to develop flowing water and micro-flow farming in a way that suits local conditions. The city has built a total of 40 circular water farming channels in reservoirs, 88 high-position pools, 4 modern farming workshops, 133 land-based circular pools, and more than 50,000 square meters of flowing water pools, with both fish production and economic benefits increasing simultaneously.
