Description

A kind of method that utilization blue-green algae prepares organic fertilizer
Technical field
The invention belongs to organic fertilizer technical field, and in particular to a kind of method that utilization blue-green algae prepares organic fertilizer.
Background technology
In some nutritious water bodys, some blue-green algaes form one layer of blue-green often in summer amount reproduction in the water surface And have the offscum of bad smell, it is referred to as " wawter bloom ", large-scale blue algae bloom is referred to as " green tide "(The red tide pair occurred with ocean Should).Green tide causes water quality deterioration, exhausts water oxygen when serious and causes the death of fish.More seriously, have in blue-green algae A little species(Such as Microcystis aeruginosa)Microcystin can also be produced(Microcystins, abbreviation MCs), contain in about 50% green tide A large amount of MCs.MCs is also the major incentive of liver cancer in addition to directly producing murder by poisoning to fish, people and animals.
It is one of Main Means that current China solves lake eutrophication pollution that blue-green algae physics, which is salvaged,.Annual blue algae bloom Phase, the serious lake of each body eutrophication has number to pull lake out with ten thousand tons of blue-green algae daily.How to solve, handle blue-green algae well and beat Accumulation problem after pulling out is to administer one of the problem of water eutrophication pollution is considered as.Blue-green algae be rich in N, P, by fermentation after Using biogas residue therein, biogas slurry, mineral nutrition can be not only better profited from, is turned waste into wealth, and can be to a certain extent Reduce chemical fertilizer to utilize, mitigate environmental pressure, with environmental benefit, Social benefit and economic benefit.
