Abstract
The invention discloses a blue algae killing method, which comprises the following steps: spraying 20 to 30 percent hydrogen peroxide, simultaneously spraying 3 to 8 percent ferrous salt or stannous salt solution, and decomposing blue algae cells by using instantaneous release energy of chemical reaction and active groups which permeate the blue algae cell walls to change molecular structures of the cells, wherein the blue algae remains become yellow solid substances in 24 hours after spraying; and then treating the remains, namely feeding 5 to 15 percent polyaluminium chloride and 0.03 to 0.08 percent polyacrylamide into the remains, simultaneously stirring the water surface by using a clean water pump in single circulation, pumping sludge by using a sludge pump after the blue algae remains are precipitated, and treating the sludge according to the conventional method; or adding 0.03 to 0.08 percent polyacrylamide into the remains, simultaneously stirring the water surface by using the clean water pump in single circulation, salvaging the blue algae remains by a tuck net, and then treating the sludge according to the conventional method, wherein the polyaluminium chloride and the polyacrylamide are water-purifying flocculating agents and can thoroughly purify the water areas.
Description
Technical field
The present invention relates to a kind of method for disinfection, especially a kind of blue algae killing method.
Background technology
At present, known blue-green algae belongs to a kind of ancient alga microbial, is subjected to the influence of weather condition, hydrologic condition, very easily cause breaking out on a large scale, since the metabolism of itself, the dissolved oxygen in the mass consumption water body, make water body smelly, the middle-and-high-ranking hydrocoles death of water.
The treatment technology of blue-green algae is mainly biological process now, comprises microbial method, plant method, animal law etc., breaks out on a large scale but all can't effectively handle blue-green algae.
Summary of the invention
In order to address the above problem, the invention provides blue algae killing method, this blue algae killing method can decompose the blue-green algae cell, changes the molecular structure of its cell, makes the alga microbials such as blue-green algae can't growth and breeding, thereby reaches the purpose of killing blue-green algae.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of blue algae killing method, carry out as follows:
1.. blue algae killing is handled: spray concentration is 20% ~ 30% hydrogen peroxide, and spray concentration is 3% ~ 8% divalent iron salt solution or tin salt solution simultaneously, the solid matter of blue-green algae yellowly after 24 hours (being the blue-green algae corpse);
2.. the blue-green algae corpse is handled:
(1). precipitation process: to add concentration be that 5% ~ 15% polymerize aluminum chloride and concentration are 0.03% ~ 0.08% polyacrylamide handling the waters, with fresh water pump the water surface is carried out single loop simultaneously and stir (playing the mixed solvent effect), blue-green algae corpse post precipitation aspirates mud with dirty pump, and mud is handled routinely;
(2). physics salvage to be handled: to add concentration be 0.03% ~ 0.08% polyacrylamide handling the waters, with fresh water pump the water surface carried out single loop simultaneously and stir (playing the mixed solvent effect), with sludge treatment routinely behind the string bag salvaging buoyant blue-green algae corpse.
The invention has the beneficial effects as follows: the utilization strong oxidizer: hydrogen peroxide and strong reductant: the chemical reaction abrupt release energy of divalent iron salt or tin salt and active group are (0.0H), cell walls by active group infiltration blue-green algae, decompose the blue-green algae cell, change the molecular structure of its cell, make the alga microbials such as blue-green algae can't growth and breeding, thereby reach the purpose of killing blue-green algae.The final product of hydrogen peroxide behind chemical reaction is oxygen again, can not bring influence and help animal survival development under water ecotope.Be aided with and be suitable for water purifying flocculating agent very widely: polymerize aluminum chloride and polyacrylamide carry out the blue-green algae corpse to be handled, and thoroughly purifies the waters.
Embodiment
Embodiment: a kind of blue algae killing method, carry out as follows:
1.. blue algae killing is handled: spray concentration is 20% ~ 30% hydrogen peroxide, and spray concentration is 3% ~ 8% divalent iron salt solution or tin salt solution simultaneously, the solid matter of blue-green algae yellowly after 24 hours (being the blue-green algae corpse);
2.. the blue-green algae corpse is handled:
(1). precipitation process: to add concentration be that 5% ~ 15% polymerize aluminum chloride and concentration are 0.03% ~ 0.08% polyacrylamide handling the waters, with fresh water pump the water surface is carried out single loop simultaneously and stir (playing the mixed solvent effect), blue-green algae corpse post precipitation aspirates mud with dirty pump, and mud is handled routinely;
(2). physics salvage to be handled: to add concentration be 0.03% ~ 0.08% polyacrylamide handling the waters, with fresh water pump the water surface carried out single loop simultaneously and stir (playing the mixed solvent effect), with sludge treatment routinely behind the string bag salvaging buoyant blue-green algae corpse.
Principle of work of the present invention is: mainly use strong oxidizer: hydrogen peroxide and strong reductant: the chemical reaction abrupt release energy of divalent iron salt or tin salt and active group are (0.0H), cell walls by active group infiltration blue-green algae, decompose the blue-green algae cell, change the molecular structure of its cell, make the alga microbials such as blue-green algae can't growth and breeding, thereby reach the purpose of killing blue-green algae.The final product of hydrogen peroxide behind chemical reaction is oxygen again, can not bring influence and help animal survival development under water ecotope.Be aided with and be suitable for water purifying flocculating agent very widely: polymerize aluminum chloride and polyacrylamide carry out the blue-green algae corpse to be handled, and thoroughly purifies the waters.
