SUMMÀRY:
Objective: We analyzed the materials on the improvement of the efficiency of wastewater treatment and ventilation emissions at building up of the local sewerage treatment plants in rural ar-eas.
Materials and methods: Modern technologies of sewage treatment at low capacity sewerage treatment plants using inert loading and treatment of ventilation emissions at the industrial ozone and sorption facilities. In the study we used the methods of expert evaluation, sanitary-epidemiological examination, and sanitary-hygienic, physico-chemical, analytical ones.
Results: The technology of deep sewage treatment at the block-modular structures of the Ecocompact series with the use of self-regenerated carriers of biocenosis “OPET” and other small sewerage treatment plants with capacity of 50-500 m3/day in rural settlements and cottage villages was considered. The technology also includes deep purification of ventilation air on the ozonizers or sorption filters. It provides an effective reduction of harmful substances in waste water and atmos-pheric emissions and creates conditions for adjusting of the size of the sanitary protection zone de-pending on the capacity of small treatment plants.
Conclusions: Improvement of the method for the treatment of residential water of the small treatment plants with a capacity of 50-500 m3/day, as well as ventilation emissions due to the inclu-sion of ozonizers or sorption filters in their plant mix allows to clean effectively the ventilator emis-sions of harmful substances and to locate rationally the small sewerage treatment plants on the plots in the small rural settlements and cottage villages in accordance with the requirements of the legislation.
