Abstract: With higher levels of organic pollutants in water through the treatment pond sedimentation purification,after the initial treatment of water into the clean pool,clean pool in the application of traditional mechanical aeration method,an increase of cultivation of probiotics with quite well-developed root system in water,floating in submerged aquatic plants to enhance the adsorption and decomposition of organic matter in water abound with poisonous and harmful substances,through a comprehensive decontamination.The water quality standards for pollution-free fresh water aquaculture and water quality testing.The use of micro -organisms,aquatic plants,cleaning of excessive nutrients in water bodies and other physical,chemical and engineering methods,compared with a low cost,power consumption is small,the control effect is good,a small disturbance on the environment is conducive to resource optimization,there are good economic efficiency and high landscape value,contribute to the overall improvement of the ecological environment,the application of biological micro-ecological environment for the pond to the prospects for rehabilitation will have a vast.
