Blue-green algae fishing and separating method
The invention relates to the technical field of environmental treatment, in particular to a blue-green algae fishing and separating method. Fished blue-green algae are subjected to pressurizing precipitation to enable gas vesicles in blue-green algae cells to be irreversibly broken to be inactivated, and the inactivated blue-green algae precipitate under the action of gravity to form algae residuedue to loss of buoyancy, so that the treatment effect of the blue-green algae is improved; algae mud with a lower water content is obtained after the algae residue is dehydrated, and can be subjectedto outward transportation or resourceful treatment, wetland microorganisms in wetland purification treatment can absorb and convert organic matters in water, filler and the plant root system can intercept insoluble suspended matters in water, clear water subjected to wetland deep purification is directly discharged back to lakesides, biological prevention and control are utilized to improve the water purification effect, the method is safer, free of side effect, green and environmentally friendly, finally, concentrated water with a high algae density is returned into an algae slurry pool through tail water treatment to be repeatedly separated, pollution caused by direct discharge can be avoided, and the purification effect is improved.
本发明涉及环境处理技术领域，具体地说，涉及一种蓝藻打捞分离方法，通过将打捞后的蓝藻进行加压沉淀可以使蓝藻细胞内伪空泡发生不可逆破裂而失活，失活蓝藻因失去浮力而在重力作用下发生沉淀形成藻渣，提高蓝藻的处理效果；藻渣脱水处理后得到含水率更低的藻泥，可外运或资源化处理，湿地净化处理中湿地微生物可吸收并转化水中的有机物，填料和植物根系可截留水中的难溶性悬浮物，经湿地深度净化的清水直接回排入湖滨，利用生物防治，提高水的净化效果，更加安全，无副作用，绿色环保，最后通过尾水处理将藻密度较高的浓水返回藻浆池中进行重复分离，可以避免直接排放造成污染，提高净化效果。
