Water quality treatment suspending bed for eutrophic water area and water treatment method thereof

Abstract

The invention discloses a water quality treatment suspension bed for a eutrophic water area and a water treatment method thereof. A ring structure floating on the water surface is used in the suspension bed; water hyacinth seedling plants are planted in the ring structure, so that the cultivation density of water hyacinth and the like is gradually increased to force the root systems of the water hyacinth in the ring structure to stretch downwards and mutually intertwine to form a three-dimensional net structure; adsorbent is evenly sprayed into the net-shaped root systems of the water hyacinth and the like in the ring structure and adhered in the net-shaped root systems; and microorganism strains used for water treatment enter into the net-shaped root systems and are adhered to the root systems and the adsorbent so as to form a three-dimensional net-structured microbiological treatment membrane. The suspension bed has water treatment functions of enrichment, biological flocculation, nitration, phosphorus accumulation, absorption, activation, filtration and the like, can regulate the circulation of ammonia, nitrogen phosphorous, sulphur, mercury and the like of polluted water quality. based on the suspension bed, the water treatment method can treat eutrophic water quality effectively has high efficiency and is convenient for control.

Description

technical field [0001] The invention relates to the technical field of sewage purification and treatment, in particular to a suspended bed for water quality treatment in eutrophic waters and a water quality treatment method thereof. Background technique [0002] Eutrophication is a phenomenon of deterioration of water quality caused by excessive content of nitrogen, phosphorus and other plant nutrients. In our country, the pollution and harm caused by eutrophication of water body have been reported more and more. Taking Dianchi Lake as an example, the eutrophication and pollution of Dianchi Lake water body has been reported in the newspapers a long time ago. However, the application of a large number of new technologies and measures has limited effect until now. Currently, comprehensive methods and comprehensive measures are not used. , the treatment effect on water eutrophication is not obvious, and the effectiveness of treatment cannot meet people's hopes and desires for ...

Taking Dianchi Lake as an example, the eutrophication and pollution of Dianchi Lake water body has been reported in the newspapers a long time ago. However, the application of a large number of new technologies and measures has limited effect until now. Currently, comprehensive methods and comprehensive measures are not used. , the treatment effect on water eutrophication is not obvious, and the effectiveness of treatment cannot meet people's hopes and desires for pollution control and environmental protection when the investment is high, and it has become a complex and difficult system project within decades; Let us all see no hope of success

[0003] At present, there is no efficient and easy-to-control method to control water eutrophication in China. The most widely used is to stock aquatic plants, such as water hyacinth, which uses its own growth and reproduction to absorb the excess nutrients in the water. However, due to the rapid reproduction of water hyacinth, it often Cause water hyacinth flooding, causing greater ecological deterioration accidents
