Efficient Technologies Of Small Wastewater Treatment Plants

Abstract

This article discusses the results of a scientific research work on the use of various types of small wastewater treatment plants for objects of various purposes in conditions of periodic use. The study was carried out on model and real wastewater with subsequent refinement of the characteristics using the calculation methods of the DWA standard.The results of the operation of laboratory facilities operated in the restart mode after a certain time are presented. As a result, the duration of restoration of the operating mode under periodic operating mode was considered for each plant under study and the effectiveness of biological wastewater treatment was determined. More promising technological solutions for small wastewater treatment plants under intermittent use conditions have been identified. According to the sum of the characteristics, the operation of the flooded biofilter system, which is capable of entering the operating mode within 5 days after a long shutdown, is highlighted. These technologies are recommended for use in resort areas and hotels.
