This article describes the method, based on the kinetics of enzyme reaction, for calculating treatment rates for wastewater effluents of varied concentrations in mixing aeration tanks and continuous flow aeration tanks. Using this method would make it possible to optimize the parameters of the biological treatment of wastewater. In addition, the authors illustrate that partitioning of the aeration space of the mixing aeration tank in a separate KU‐200 compact installation, which is intended for wastewater treatment from small sources, would make it possible to increase its efficiency by a factor of 1.8.
Рассмотрены основные способы интенсификации биологической очистки сточных вод путем воздействия химических, физических и биологических факторов. Обоснована целесообразность применения биотехнологических методов при пусконаладочных работах на сооружениях биологической очистки в режимах нитрификации и денитрификации, основанных на использовании биолого-ферментных препаратов, магнитной обработки и освещения. Приведены результаты исследований для городских сточных вод на модельной установке биореакторов в режиме нитрификации и денитрификации. The main methods of intensifi cation of biological wastewater treatment by chemical, physical and biological factors are considered. The expediency of using biotechnological methods during commissioning works on biological treatment facilities in the modes of nitrifi cation and denitrifi cation, based on the use of biologic-enzyme preparations, magnetic treatment and lighting, is substantiated The results of research for urban wastewater on the model installation of bioreactors in the mode of nitrifi cation and denitrifi cation are given.
Проанализированы причины критических ситуаций на очистных сооружениях коммунального водоотведения. Проведено обследование локальных очистных сооружений микрорайона в критической ситуации отказа и определены проблемы, обусловленные сбросом либо недоочищенных, либо полностью неочищенных сточных вод в водоём. Для восстановления функционирования очистных сооружений разработан оптимальный технологический режим с учетом изменения подачи воздуха, ввода биопрепаратов, добавления пероксида водорода и использования светодиодов в аэробной части сооружений. The causes of critical situations in sewage treatment plants for municipal water disposal are analyzed. A survey of local treatment facilities of the microdistrict in a critical failure situation was carried out and problems were identifi ed, caused by the discharge of either under-treated or completely untreated sewage into the reservoir. To restore the functioning of treatment facilities an optimal technological regime has been developed, taking into account changes in air supply, introduction of biologics, addition of hydrogen peroxide and the use of LEDs in the aerobic part of structures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
