Embodiment 1
[0027] Such as figure 1 A method for deep dehydration of cyanobacteria is shown. In this method, the cyanobacteria produced by the algae water separation station are conditioned and then press-filtered to obtain cyanobacteria mud with a water content below 60%. The filtered water is passed through lye, gas Floating tank, AO biological tank treatment and sedimentation tank meet the urban sewage discharge standard;
[0028] The lye adjusts the pH of the filtered water to neutral or slightly alkaline, and the air flotation tank uses coagulants and coagulants to react with the filtered water to form flocs and separate solids and liquids through air flotation .
[0029] Before the cyanobacteria is conditioned, air flotation sludge is added for mixing.
[0030] The air flotation sludge is obtained through reaction in an air flotation tank.
[0031] Said cyanobacteria adopts blooming cyanobacteria, which refers to cyanobacteria salvaged from eutrophic lakes or other still water bo...
Embodiment 2
[0039] A method for deep dehydration of cyanobacteria. In the method, the cyanobacteria produced by the algae water separation station are conditioned and then press-filtered to obtain cyanobacteria with a water content below 60%. The filtered water is passed through lye, air flotation tank, After AO biological pool treatment and sedimentation tank, it reaches the urban sewage discharge standard;
[0040] The lye adjusts the pH of the filtered water to neutral or slightly alkaline, and the air flotation tank uses coagulants and coagulants to react with the filtered water to form flocs and separate solids and liquids through air flotation .
[0041] Before the cyanobacteria is conditioned, air flotation sludge is added for mixing.
[0042] The air flotation sludge is obtained through reaction in an air flotation tank.
[0043] Said cyanobacteria adopts bloom cyanobacteria, which refers to cyanobacteria salvaged from eutrophic lakes or other still water bodies that form blooms...
Embodiment 3
[0051] A method for deep dehydration of cyanobacteria. In the method, the cyanobacteria produced by the algae water separation station are conditioned and then press-filtered to obtain cyanobacteria with a water content below 60%. The filtered water is passed through lye, air flotation tank, After AO biological pool treatment and sedimentation tank, it reaches the urban sewage discharge standard;
[0052] The lye adjusts the pH of the filtered water to neutral or slightly alkaline, and the air flotation tank uses coagulants and coagulants to react with the filtered water to form flocs and separate solids and liquids through air flotation .
[0053] Before the cyanobacteria is conditioned, air flotation sludge is added for mixing.
[0054] The air flotation sludge is obtained through reaction in an air flotation tank.
[0055] Said cyanobacteria adopts blooming cyanobacteria, which refers to cyanobacteria salvaged from eutrophic lakes or other still water bodies that form bloom...
