Embodiment 1

[0040] This embodiment provides a method for assisting algicidal bacteria to dissolve algae, by adding algogenic bacteria to achieve the purpose of removing pollutants in the water body-algae, including the following steps, step 1, adding algogenic bacteria and H to the water body 2 o 2 , through H 2 o 2Carry out pre-oxidation of algal substances in the water body, and at the same time of pre-oxidation, carry out the first stage stirring 300r / min-350r / min, which is used to break the algae substances in the water body. Then, the algae-dissolving bacteria are lysed by the second-stage stirring at 100r / min-150r / min. At this stage, a large number of algae-dissolving bacteria obtained in step 1 begin to lyse the algae.

[0041] Add H 2 o 2 Increase the concentration of dissolved oxygen in the water, and the high-speed stirring of the first stage 300r / min-350r / min breaks up part of the algae and provides conditions for the reproduction and growth of alginolytic bacteria, which i...

Embodiment 2

[0044] The battery of this embodiment adopts lead-acid battery, and the motor of the stirring system is arranged inside the casing; the volume of the bacterial agent storage tank is 5L, H 2 o 2 The volume of the storage tank is 2L. The floating system 2 is made of lightweight foamed plastic. h 2 o 2 The storage tank, the metering pump and the gate valve are connected by pipelines; the bacteria storage tank, the metering pump and the gate valve are connected by pipelines; the chlorophyll measuring device, the bacteria storage tank, the H 2 o 2 The storage tank and the surface of the box are made of stainless steel.

[0045] Comply with the above technical solutions, such as Figure 1-4 As shown, this embodiment provides an in-situ mixing and oxygenation device for assisting algae-dissolving algae, including a box body 1, a floating system 2, and a bacterium injection system 3. The box body 1 is suspended in water by the buoyancy of the floating system 1, The bacterium in...

Abstract

The invention discloses a method for assisting algicidal bacteria for algae-lysing and an in-situ mixing and oxygenating device. The device comprises a tank body, a floating system and a bacteria throwing system, wherein the tank body is suspended in water through a buoyancy force of a float system; the bacteria throwing system is located in the tank body. The device also comprises a dosing system and a stirring system, wherein the dosing system comprises an H2O2 storage tank; the H2O2 storage tank is located in the tank body; the stirring system is located under the tank body, and comprises a rotary shaft; an upper paddle and a lower paddle are arranged on the rotary shaft and inclined to a horizontal surface; the upper paddle adopts a single-side sawtooth-shaped structure. According to the device provided by the invention, at the earlier stage of operation, the concentration of dissolved oxygen in water is increased by utilizing the H2O2, the paddles run at high speed so as to break part of algae, and a growth condition of the algicidal bacteria is provided, which is the key of efficiently removing algae through the device. At the later stage of operation, the stirring device runs at low speed so as to promote the algicidal bacteria and the algae to mix sufficiently, the whole system is at a suspended state, the occurrence of deposit is prevented through stirring, meanwhile, the dissolved oxygen with a certain concentration is contained in the water, the update of a liquid level is promoted, and meanwhile, growth and reproduction of the algae are inhibited.

Description

technical field [0001] The invention belongs to the technical field of treatment of polluted water bodies, and relates to a method for controlling algae in eutrophic water bodies, in particular to a method for assisting algae-dissolving bacteria to dissolve algae and an in-situ mixing and oxygenating algae-dissolving device. Background technique [0002] The global water environment is polluted, leading to severe eutrophication of water bodies, and harmful algae blooms continue to occur in different parts of the world. Algal blooms can wreak havoc on aquatic ecosystems, and besides hampering tourism and shipping, many of the algae that cause blooms are poisonous. This phenomenon has seriously affected the quality of the water environment and the ecological safety of water bodies, and caused great losses to human health, biological safety, and economic and social development. Eutrophication caused by pollution in major rivers, reservoirs, and lakes in my country is common. T...
