Abstract

SBR tehnološki postupak korišten je za biološko pročišćavanje komunalnih otpadnih voda. Istraživan je utjecaj duljine trajanja i naizmjeničnost aerobnih i anoksičnih faza u radu SBR-a s ciljem učinkovitog uklanjanja dušikovih spojeva procesima nitrifikacije i denitrifikacije, kao i uklanjanja ugljikovih i fosfornih spojeva. Povećanjem broja naizmjeničnih perioda aeracije povećava se aktivnost simultanog procesa nitrifikacije i denitrifikacije, smanjuje se akumulacija NOx –N spojeva, a zapažena je i visoka učinkovitost provođenja biološkog procesa uklanjanja fosfora.

Abstract (english)

The biological treatment of municipal wastewater by applying the SBR technology was used. The effect of duration and alternation of aerobic and anoxic stages in SBR due to efficient nitrogen removal via nitrification and denitrification processes as well as carbon and phosphorus removal was investigated. With the increasing number of alternating aerobic stages, the activity of simultaneous nitrification and denitrification increases, the accumulation of NOx-N decreases, and high efficiency of biological phosphorus removal was observed.
