Показано, что аэробная очистка смеси сточной воды и активного ила в присутствии непрерывного импульсного электромагнитного поля частотой 16 Гц и магнитной индукцией не более 0,5 мкТ ускоряет процесс аммонификации на 25 %, нитрификации и денитрификации на 15 %, снижает ХПК приблизительно на 20 %. Отмечена интенсивность увеличения биомассы активного ила и скорости его осаждения.</p></abstract><trans-abstract xml:lang="en"><p>The effect of pulsed EMF with a pulse repetition frequency of 16 Hz on the decomposition of organic compounds in wastewater in the presence of activated sludge microorganisms has been studied. It is shown that aerobic purification of a mixture of wastewater and activated sludge in the presence of a continuous pulsed electromagnetic field with a frequency of 16 Hz and a magnetic induction of no more than 0.5 μT accelerates the process of ammonification by 25 %, nitrification and denitrification by 15 %, reduction of COD by approximately 20 %.The intensity of the increase in the biomass of activated sludge and the rate of its deposition were noted.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>очистка сточных вод</kwd><kwd>активный ил</kwd><kwd>импульсное электромагнитное поле</kwd><kwd>удаление биологического азота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>active sludge</kwd><kwd>biological nitrogen removal</kwd><kwd>impulse electromagnetic field</kwd><kwd>wastewater treatment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Beretta G..
