Microbial treatment method for eutrophication of landscape water body

Abstract

The invention provides a microbial treatment method for eutrophication of a landscape water body, which comprises the specific steps of step 1, chemical phosphorus removal, specifically, adding a chemical phosphorus removal agent into the landscape water body; step 2, microbial purification, specifically, adding a composite microbial remediation agent into the landscape water body; and 3, carryingout aquatic plant assisted purification, carrying out filler biofilm culturing, placing the filler subjected to biofilm culturing at the lower part of a floating bed, and placing the biological floating bed on a landscape water body to be treated. According to the method, a chemical method and an ecological method are organically combined, and phosphate in the water body is quickly removed by utilizing the advantage of quick effect of the chemical method, so that flora playing a main role in subsequently added microbial inoculants and filler biofilms can quickly establish advantages, the water body is quickly and continuously treated, eutrophication is avoided, the flora in the microbial inoculum and the filler biofilm culturing is relatively reasonable, and the effect is relatively quick.

Description

technical field [0001] The invention relates to the technical field of landscape water body treatment, in particular to a microbial treatment method for landscape water body eutrophication. Background technique [0002] Most of the landscape water in cities is artificially constructed water bodies, most of which are in a closed or semi-closed state, with poor fluidity and low flow rate. The massive reproduction of algae and microorganisms makes the water body eutrophic, which can easily lead to low water transparency, serious odor, and even the death of aquatic animals, which is difficult to recover from. [0003] At present, the methods for treating eutrophication of landscape water bodies mainly include physical methods, chemical methods and ecological methods. Among them, physical methods can only use physical methods to remove existing algae. The state of eutrophication will be restored; the chemical method can achieve obvious algae removal effect in a short time and im...

Problems solved by technology

[0002] Most of the landscape water in cities is artificially constructed water bodies, most of which are in a closed or semi-closed state, with poor fluidity and low flow rate. A large number of algae and microorganisms multiply, making the water body in a state of eutrophication, which can easily lead to low transparency of the water body, serious odor, and even the death of aquatic animals, which is difficult to recover

[0003] At present, the methods for treating eutrophication of landscape water bodies mainly include physical methods, chemical methods and ecological methods. Among them, physical methods can only use physical methods to remove existing algae. The state of eutrophication will be restored; the chemical method can achieve obvious algae removal effect in a short time and improve the transparency of the water body, but it cannot remove nutrients such as nitrogen and phosphorus out of the water body, and long-term use of low-concentration algicides will also Make algae resistant to pesticides; although the ecological method can solve the problem of eutrophication in the water body from the root, it is often due to the unreasonable ratio of the bacterial flora, which leads to poor control effect, and there are also defects of slow effect
