Abstract

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.

低频脉冲电磁场对生活污水净化的影响

研究了脉冲重复频率为16 Hz的脉冲电动势在活性污泥微生物存在下对废水中有机物分解的影响。结果表明，在频率为16 Hz、磁感应强度不大于0.5 μT的连续脉冲电磁场条件下，对废水和活性污泥进行好氧净化，可使氨化过程加快25%，硝化和反硝化过程加快15%，COD降低约20%。注意到活性污泥生物量的增加强度及其沉积速度。

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
