Description

50.00 мг/л) достигаетс  концентрацией активного ила 7-15 г/л.50.00 mg / l) is achieved by an activated sludge concentration of 7-15 g / l.

Предлагаем: й спосс б позвол ет очищать сточные воды с высокой концентрацией загр знений при максимальной окислительной мощности сооружени  5625 г/м в сутки и периоде аэрации 24 ч.We offer: th sposs b allows purification of waste waters with a high concentration of contaminants at a maximum oxidizing power of the facility of 5625 g / m per day and a period of aeration of 24 hours.

Пример 1. В аэротенк - смеситель с регенератором, заполненный активным илом (концентраци  10 г/л, зольность 30%), приготовленным изExample 1. In an aeration tank - a mixer with a regenerator, filled with activated sludge (concentration 10 g / l, ash content 30%) prepared from

почвы, подвергавшейс  длительное врем , проливам продуктов производства СЖЗ высоконцентрированных сточных вод того же производства, на агаризованную питательную среду с последующим выделением микроорганизмов родов Ptanococcu3,Peano3arclna,Bo(ci&eu9,Bacterium подают пpo ышлeннyю сточную воду с ХПК-5300мг/л,БПК полн.-444Змг/лsoil podvergavsheys long time, straits manufacturing products SZHZ vysokontsentrirovannyh wastewater the same production on agar nutrient medium and subsequent isolation Ptanococcu3 genera of microorganisms, Peano3arclna, Bo (ci & eu9, Bacterium fed ppo yshlennyyu wastewater with COD 5300mg / L, BOD full-444Zmg / l

и эломентм: азот 90 мс/ч, фосфор 45 мг/л.and elomentm: nitrogen 90 ms / h, phosphorus 45 mg / l.

Подачу воздуха в аэротенк осущостл ют в количестве, обеспечивающем содержание растворенного кислорода во вторичном отстойнике не менее 1 мг/л период аэрации 24 ч.Air is supplied to the aeration tank in an amount that ensures that the content of dissolved oxygen in the secondary settling tank is not less than 1 mg / l of aeration period of 24 hours.

Степень очистки сточных вол составила 97%, ХПК (очищенной воды) 236,5 мг/л, ВПК 145,7 мг/л. Процессы нитрификации протекают удовлетворительно .The degree of wastewater treatment was 97%, COD (purified water) 236.5 mg / l, VPK 145.7 mg / l. The nitrification processes proceed satisfactorily.

Пример 2. В аэротенк - смеситель с активным илом, приготовленным , как в примере 1, подают сточную воду (ХПК 7168 мг/л, ВПК полн. 5734 мг/л) и биогенные элементы (азот 100 мг/л, фосфор 50 мг/л).Example 2. In the aeration tank with activated sludge, prepared as in example 1, serves wastewater (COD 7168 mg / l, MIC total. 5734 mg / l) and biogenic elements (nitrogen 100 mg / l, phosphorus 50 mg / l).
