METHOD FOR BIOLOGICAL TREATMENT OF ANIMAL BREEDING EFFLUENT AND DEVICE THEREFOR

摘要

The process of biological treatment of animal farm effluent is of two-stage type and comprises first stage of treatment with anaerobic flora and second stage of aerobic treatment with filament micro-fungi. An independent claim is also included for installation for conducting process as claimed, comprising: (i) first installation for decantation of effluent and treatment of decanted matter with anaerobic flora; (ii) second installation for treatment of effluent recovered from the first installation with filament fungi in presence of oxygen; (iii) system supplying farm effluent to the first installation; (iv) system transferring effluent from the first installation to the second installation; and (v) system for removal of treated effluent from the second installation.
