Embodiment 1

[0026] A method for purifying eutrophic water body, comprising: first putting microbial preparations and filter-feeding fish in the water body to be purified. Then monitor the color change of the water body in real time or regularly. Finally, salvage operations are carried out in specific areas according to the color of the water body. The microbial preparation includes: nitrifying bacteria, bacillus, and photosynthetic bacteria, calculated according to the number of colonies, nitrifying bacteria: bacillus: photosynthetic bacteria=1:0.5:2. The filter-feeding fish includes: silver carp and bighead carp. The feeding ratio of silver carp and bighead carp is calculated by quantity, silver carp: bighead carp=1:0.4.

[0027] The method for monitoring the color change of the water body comprises:

[0028] S1. Before putting in filter-feeding fish, scan and record the color of the water body in a full range.

[0029] S2. After releasing the filter-feeding fish, use the method of d...

[0037] A method for purifying eutrophic water body, comprising: first putting microbial preparations and filter-feeding fish in the water body to be purified. Then monitor the color change of the water body in real time or regularly. Finally, salvage operations are carried out in specific areas according to the color of the water body. The microbial preparation includes: nitrifying bacteria, bacillus and photosynthetic bacteria, calculated according to the number of colonies, nitrifying bacteria: bacillus: photosynthetic bacteria=1:0.3:1. The filter-feeding fish includes: silver carp and bighead carp. The feeding ratio of silver carp and bighead carp is calculated by quantity, silver carp: bighead carp=1:0.7.

[0038] The method for monitoring the color change of the water body comprises:

[0039] S1. Before putting in filter-feeding fish, scan and record the color of the water body in a full range.

[0040] S2. After releasing the filter-feeding fish, use the method of dr...

Embodiment 3

[0046] A method for purifying eutrophic water body, comprising: first putting microbial preparations and filter-feeding fish in the water body to be purified. Then monitor the color change of the water body in real time or regularly. Finally, salvage operations are carried out in specific areas according to the color of the water body. The microbial preparation includes: nitrifying bacteria, bacillus, and photosynthetic bacteria, calculated according to the number of colonies, nitrifying bacteria: bacillus: photosynthetic bacteria=1:0.7:3. The filter-feeding fish includes: silver carp and bighead carp. The feeding ratio of silver carp and bighead carp is calculated by quantity, silver carp: bighead carp=1:0.3.

[0047] The method for monitoring the color change of the water body comprises:

Abstract

The invention provides a method for purifying a eutrophic water body to overcome the defects in the prior art. The method comprises the following steps: firstly, putting filter-feeding fishes into thewater body to be purified; secondly, monitoring the color change of the water body in real time or periodically; and lastly, performing salvage operation in a specific area according to the color ofthe water body. A method for monitoring the color change of the water body comprises the following steps: S1, scanning and recording the color of the water body in a full range before putting the filter-feeding fishes; S3, scanning and recording the color of the water body in a full range in real time or periodically by cruising with an unmanned aerial vehicle after putting the filter-feeding fishes; S3, comparing a scanning record obtained in the step S2 with a scanning record obtained in the step S1, and marking color change areas respectively; S4, performing putting or salvage operation inthe color change areas according to the positions of the color change areas obtained in the step S3 and a color change relationship. The technology has the advantages of rapidness, low cost, capability of realizing continuous monitoring and easiness in operation.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a method for purifying eutrophic water bodies. Background technique [0002] Eutrophication refers to that under the influence of human activities, a large amount of nutrients such as nitrogen and phosphorus required by organisms enter slow-flowing water bodies such as lakes, rivers, bays, etc., causing algae and other plankton to multiply rapidly and dissolve water bodies. Oxygen levels drop, water quality deteriorates, and fish and other organisms die in large numbers. Under natural conditions, lakes also transition from oligotrophic to eutrophic, but this natural process is very slow. However, the eutrophication caused by the artificial discharge of industrial wastewater and domestic sewage containing nutrients can appear in a short period of time. When eutrophication occurs in the water body, planktonic algae multiply in large numbers, forming a water...
