Description
Изобретение относитс к спосоЬам биохимической очистки сточных вод активным илом и может быть использовано в химической промышленности при вводе в действие сооружений биологической очистки.The invention relates to methods of biochemical wastewater treatment with activated sludge and can be used in the chemical industry during the commissioning of biological treatment facilities.
Целью изобретени вл етс ускорение прироста биомассы.The aim of the invention is to accelerate the growth of biomass.
Способ осуществл ют следующим образом .The method is carried out as follows.
К сточной воде (кубовый остаток) производства метанола с ХПК 1400- 1425 кг/л и ЬПК 810-825 мг/л добавл ют раствор адипиновой кислоты или сточные воды производства капролактама с таким расчетом, чтобы содержание адипиновой кислоты в сточной воде производства метанола составило 50-550 мг/л. Далее сточную воду обогащают биогенными элементами из расчета N-NH| 3,0-7,0 мг/100 мг БПК иAdipic acid solution or caprolactam production waste water is added to wastewater (vat residue) from methanol production with COD 1400-1425 kg / l and LPC 810-825 mg / l so that adipic acid content in methanol production waste water is 50 -550 mg / l. Further, waste water is enriched with nutrients based on N-NH | 3.0-7.0 mg / 100 mg BOD and
Р - 0,2-0,5 мг/100 мг БПК, нейтрализуют до рН 7,5-8,5 и непрерывно подают в первый коридор четырехкори- дорного аэротенка с активным илом, врем очистки составл ет 12-16 ч.P - 0.2-0.5 mg / 100 mg BOD, neutralized to a pH of 7.5-8.5 and continuously fed into the first corridor of a four-aerial aerotank with active sludge, the cleaning time is 12-16 hours.
П р и м е р 1 (по прототипу). Сточную воду предпри ти с ХПК 1423 мг/л и БПК 825 мг/л инокулиру- ют микрофлорой. В аналогичную пробу сточной воды добавл ют 150 мг левулиновой кислоты и также иноку- лируют микрофлорой. Пробы аэрируют в течение 1-3 сут. Количество бактерий на третьи сутки составл ет в контрольной пробе 10 -105 млн/мл, прирост биомассы 150 мг/л (принимаетс за 100%). В оптимальной пробе количество бактерий на третьи сутки составл ет 40-105 млн/мл, прирост биомассы 370 мг/л.PRI me R 1 (prototype). Sewage water with a COD of 1423 mg / l and BOD 825 mg / l is inoculated with microflora. 150 mg of levulinic acid is added to a similar sample of wastewater and also inoculated with microflora. Samples are aerated for 1-3 days. The number of bacteria on the third day was 10 -105 mln / ml in the control sample, the biomass increase was 150 mg / l (taken as 100%). In the optimal sample, the number of bacteria on the third day is 40-105 million / ml, the biomass increase is 370 mg / l.

П р и м е р 2. Сточную воду с ХПК кг/л и ВПК 810 мг/л (контрольна проба) инокулируют микрофлорой и аэрируют в течение 1-3 сут. Количество бактерий на третьи сутки составл ет 12-105 млн/мл, прирост биомассы 170 мг/л (эта величина принимаетс за 100%).PRI mme R 2. Sewage water with a COD of kg / l and VPK 810 mg / l (control sample) is inoculated with microflora and aerated for 1-3 days. The number of bacteria on the third day is 12-105 million / ml, the biomass increase is 170 mg / l (this value is taken as 100%).
ПримерЗ. В сточную воду пред-jQ при ти с ХПК ЙОО мг/л и ВПК 810 мг/л добавл ют адипиновую кислоту в количестве 50 мг/л, инокулируют микрофлорой и аэрируют в течение 1-3 сут. Количество бактерий на третьи сутки сос- тавл ет 2510 мли/мл. Прирост биомассы составл ет мг/л или 158,8% по сравнению с контролем.Example Adipic acid in the amount of 50 mg / l is added to the waste water of pre-jQ with COD YOOH mg / l and MIC 810 mg / l, inoculated with microflora and aerated for 1-3 days. The number of bacteria on the third day is 2510 ml / ml. The biomass increment is mg / l or 158.8% compared with the control.
Пример. В сточную воду предсоставл ет 12-106 млн/мл. Прирост биомассы 710 мг/л или 417,6% от контрольной пробы.Example. It represents 12-106 million / ml into waste water. Biomass growth is 710 mg / l or 417.6% of the control sample.
Примерб. В сточную воду предпри ти с ХПК ЙОО мг/л и ВПК &1С мг/л добавл ют адипиновую кислоту в количестве 650 мг/л, инокулируют микрофлорой и аэрируют в течение 1-3 сут.Example Adipic acid in the amount of 650 mg / l is added to the wastewater of the plant with COD YOOH mg / l and MIC & 1C mg / l, inoculated with microflora and aerated for 1-3 days.
Количество бактерий на третьи сутки составл ет 5 ТО6 млн/мл. Прирост биомассы 320 мг/мл или 188,2% от контрольной пробы.The number of bacteria on the third day was 5 TO6 million / ml. Biomass gain 320 mg / ml or 188.2% of the control sample.
