| 摘要 |
<p>The invention relates to a device and a technique for the digestion of effluents by fluidised beds and limicolous filtration, said device consisting of four independent, intercommunicating tanks, without sludge recirculation, for treating liquid effluents in a vertical biological manner, with biological stratification by means of air injection pressure control, and filtration devices comprising elements which favour the adhesion of lime. The waste effluents follow a continuous and ordered flow throughout the process, resulting in water which satisfies the regulations for the discharge of effluents to receiving bodies of water and sewers.</p> |
