Description

Изобретение относится к способам биологической очистки в аэротенках сточных вод, содержащих органические соединения, концентрация которых характеризуется величинами ХПК (хими- 5 ческое потребление кислорода) и ВПК (биохимическое потребление кислорода).The invention relates to methods for biological treatment in aerotanks of sewage containing organic compounds whose concentration is characterized by COD (chemical oxygen consumption) and MIC (biochemical oxygen consumption).

Целью изобретения является повышение степени очистки сточных вод и экономичности процесса. <0The aim of the invention is to increase the degree of wastewater treatment and process efficiency. <0

Приме р. Очистке подвергают сточную воду химических предприятий, содержащую органические соединения в концентрации 160 мг/л по ХПК и 130 мг/л по ВПК. В смесь активного 15 ила, находящуюся в аэротенке, подаютPrimer p. Purification is subjected to waste water of chemical enterprises, containing organic compounds at a concentration of 160 mg / l by COD and 130 mg / l by VPK. In a mixture of 15 active sludge, located in the aeration tank, serves

биогенные элементы, азот и фосфор с одинаковой дозой по истечении различного времени от начала аэрации. Доза азота принята из расчета 4 мг, фосфора 1,5 мг на каждые 100 мг ВПК сточной воды. После расчетного времени аэрации смесь активного ила из аэротенка подают в отстойник, где происходит разделение ее на активный ил, который возвращают в аэротенк и очищенную воду.nutrients, nitrogen and phosphorus with the same dose after a different time from the start of aeration. The dose of nitrogen is taken at the rate of 4 mg, phosphorus 1.5 mg for every 100 mg of MIC wastewater. After the estimated aeration time, the mixture of activated sludge from the aero tank is fed to a sump, where it is separated into activated sludge, which is returned to the aeration tank and purified water.

Показатели качества очищенной воды приведены в табл.1.The quality indicators of purified water are given in table 1.

Сравнительные данные приведены в табл.2.Comparative data are given in table 2.
