Intensive Aquaculture Wastewater Treatment by Photochemical Recovery Technology for Pollutant Removal and Water Recycling

Recently, the pollution from pond aquaculture waste water has become more and more serious. In order to perfectly deal with such problem, the paper discussed the feasibility of using photochemical reactivity to remove pollutants through improving pond aquatic ecosystem from wastewater with the aim of water recycling and zero discharge. A photochemical treatment system (PTS) was designed that used photochemical reactivity to treat the polluted aquaculture wastewater. A spot observation method has been used in discussing the reactivity for the treatment of pond aquaculture wastewater with this system on a shrimp farm in Hainan province of China. The result showed that culture pond with PTS could realize progressive efficiency of pollutant removal without water exchange in a recirculating system, which could perfectly meet the need of environment protection and culture production.
