Description
О) (ХO) (X
Изобретение относитс к биологи ческой очистке сточных вод от соединений азота и может быть использовано на предпри ти : : химической, микро;биологической и других отраслей промышленности , сбрасывающих в канализацию азотсодержащие загр знени ..The invention relates to the biological treatment of wastewater from nitrogen compounds and can be used in the enterprise:: chemical, micro, biological and other industries that discharge nitrogen-containing contaminants into the sewage system.
Цель изобретени - сокращение длительности процесса.The purpose of the invention is to reduce the duration of the process.
Способ осуществл ют следующим образом.The method is carried out as follows.
Обрабатьгоаемую сточную воду, содержащую нар ду с органическими соединени ми, аммонийньй азот, подвергают аэрации с активньм илом при гН,2 18-25. Образующийс в этих уелоВИЯХ активный ил состоит из смеси микроорганизмов , окисл ющих органичекие вещества, нитрифицирующих и денитрифицирующих микроорганизмов, при этом скорости нитрификации и денитрификации уравниваютс и необходимость в проведении-отдельной стади денитрификации отпадает.The treated wastewater containing ammonia nitrogen along with organic compounds is subjected to aeration with activated sludge at rH 2 18-25. The activated sludge formed in these fields consists of a mixture of microorganisms, oxidizing organic substances, nitrifying and denitrifying microorganisms, while the rates of nitrification and denitrification are equalized and the need for a separate denitrification stage is eliminated.
П р и м .е р 1 . Сточную воду, содержащую аммонийного азота 700 мг N/л, органических веществ 2000 мг БПК/л, подвергают аэрации с активным илом. Возраст активного ила поддерживают равным 12 сут. rHz иловой смеси 18. Очищенна вода содержит органических веществ 15 мг БПК/л, соединений азота 140 мг N/л. Длительность процесса 30 ч.P r and m p 1. Sewage water containing ammonium nitrogen 700 mg N / l, organic substances 2000 mg BOD / l, is subjected to aeration with activated sludge. The age of activated sludge is maintained at 12 days. rHz sludge mixture 18. Purified water contains organic matter 15 mg BOD / l, nitrogen compounds 140 mg N / l. The process time is 30 hours.
Пример 2..Сточйую воду, содержащую аммонийного азота 700 мг N/л органических веществ 2000 мг БПК/л, подвергают аэрации с-активным илом. Возраст активного ила поддерживают равным 30 сут-. гН2 иловой смеси 23. Очищенна вода содержит органических веществ 15 мг БПК/л, соединений азота 140 мг N/л. Длительность процесса 12 ч.Example 2. Sewage water containing ammonium nitrogen 700 mg N / l organic matter 2000 mg BOD / l, is subjected to aeration with active sludge. The age of activated sludge is maintained at 30 days. rH2 sludge mixture 23. Purified water contains organic matter 15 mg BOD / l, nitrogen compounds 140 mg N / l. The process duration is 12 hours.
П р и м е р 3. Сточную воду, содержащую аммонийного азота 700 мг N/л органических веществ2000 мг БПК/л, подвергают аэрации с активным илом.PRI me R 3. Sewage water containing ammonium nitrogen 700 mg N / l organic matter 2000 mg BOD / l is subjected to aeration with activated sludge.
iВозраст активного или 47 сут. гЕ иловой смеси 25. Очищенна вода содержит органических веществ 15 мг БПК/л, соединений азота 140 мг N/л. Длительность процесса 33 ч.iActive active or 47 days. gE sludge mixture 25. Purified water contains organic matter 15 mg BOD / l, nitrogen compounds 140 mg N / l. The process time is 33 hours.
Предлагаемый способ по сравнению с известным обеспечивает сокращение длительности процесса с 72 до 1237 ч за счет проведени процессов нитрификации и денитрификации в аэроных услови х, что стало возможным только при предложенных параметрах процесса - при гН2, 18-25 и возрасте активного ила 12-47 сут.In comparison with the known method, the proposed method reduces the duration of the process from 72 to 1237 hours by carrying out the processes of nitrification and denitrification under aeronautical conditions, which became possible only with the proposed process parameters — with rH2, 18–25 and the age of activated sludge 12–47 days .
