FIELD: waste water treatment.
SUBSTANCE: invention relates to apparatuses for treating household and compositionally related industrial waste waters as well as landscape waste waters and can be used in communal services of villages, urban settlements, tourist complexes, large recreation centers, when treating landscape sewages, e.g. from fur farming areas, aperies, food industry enterprises. Plant comprises filtering self-cleaning apparatus, consumption equalizer, reagent system, clarifier, post-treatment bioreactor, and cleaned water disinfection apparatus. Clarifier is constructed in the form of adhesion apparatus with ascending waste water flow and it is filled with brushing packing. Post-treatment bioreactor is provided with brushing packing and air lift recesses. Disinfection apparatus is constructed in the form of three filter steps filled with each step-specific grainy catalyst. First filter step has descending waste water flow and the second and third ones have ascending waste water flow and bubbler system.
EFFECT: increased impurities removal efficiency, simplified operation, reduced dimensions of equipment, and reduced operation expenses.
