湖库水华治理的微电流电解抑藻技术研究

Inhibition of cyanobacteria by low- amperage electric current electrolysis in water bloom control of lake and reservoir

相比于现有的水华末端治理方式,采用以预防为主的思路进行水华防控,避免水华发生带来的不利影响,是更为经济有效、生态友好的水华治理措施。详细阐述了控制藻类"种源"的微电流电解抑藻技术,对微电流电解抑藻技术的最佳应用时机、技术原理、应用效果等进行了分析,深入探讨了微电流电解技术抑制湖库藻类生长的机理,同时开展了技术应用研究。结果表明,移动式微电流电解对湖泊藻类生长具有良好的抑制效果,2 h的处理可使50 m3水体中85%的藻类失活。

Compared with the traditional algae treatment mode that is conducted after the bloom, the treatment measure that prevents the algae bloom from its occurring can avoid the unfavorable influence, which is more economic, effective, and environ-mental friendly. The inhibition of cyanobacteria species sources by low-amperage electric current electrolysis is introduced, and the best application time, mechanisms and effects of the technology are analyzed. The inhibition mechanism of cyanobacteria in lake and reservoir by low-amperage electric current electrolysis are further discussed and the application study was carried out. The result shows that the inhibition of algae by the mobile equipment of low -amperage electric current electrolysis for water bloom control was effective, 85% of the algae in the water area of 50m3 was inactivated by 2h treatment.
