Embodiment Construction

[0024] The governance process of the first embodiment is as follows figure 1 As shown, only three steps are included: the mechanical removal of floating objects on the water surface, the promotion of fluidization of the water body, and the cultivation of biofilm. This treatment method is suitable for the treatment of waters with a water depth below 0.5 meters and obvious blue-green algae blooms. Because the water depth is relatively shallow, the degree of hypoxia at the bottom of the water is not serious, and no aeration and oxygenation steps are required.

[0025] Generally, in eutrophic waters, algae, mainly blue-green algae, accumulate in large quantities on the water surface to form obvious algae blooms, and mixed with some leaves, garbage, dead fish, etc. to form floating objects on the water surface, so the first step of treatment The first step is to take the step of mechanical removal of floating objects on the water surface, remove a large amount of algae enrichment ...

Abstract

The invention discloses a synthesis treatment method for eutrophic water area, which comprises following steps: a. clearing the floater on water composed of algae water bloom by machine to take away mass algae particle and eliminate content of nitrogen and phosphor; b. using water-flow construction device to drive and promote water flow and destroy the over breeding of algae; c. cultivating biomembrane with microbe carriers in water to degradate pollutant.

Description

technical field [0001] The invention relates to a method for comprehensive treatment of eutrophic waters, which is mainly used for comprehensive treatment of water quality in surface waters such as lakes, rivers, reservoirs, pond landscape waters and other surface waters where high eutrophication causes a large number of algae outbreaks. Background technique [0002] There are many eutrophic surface waters in my country, whether it is large lakes such as Dianchi Lake or Taihu Lake, or small park lakes in cities, closed rivers, etc., many of which have been severely eutrophicated. In eutrophic surface waters, excess nutrients such as nitrogen and phosphorus often lead to a large number of algal blooms such as blue green algae, and often form a thick floating layer of algae on the water surface, which is called "algae bloom". "Water bloom" is called an ecological cancer, which has greatly deteriorated the water environment, resulting in a foul smell in the water and a large nu...
