Description
(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ ОРГАНИЧЕСКИХ . . ВЕЩЕСТВ, ПРЕИМЭТтЩСТВЕННО НЕФТЕСОДЕРЖМтЩХ Получают достаточно концентрированные микробные суспензии каждой из культур - клеток. Два раза в мес ц в отдельно сто щую емкость подают биопленку, осевшую во вторичном отстойнике, и туда же внос т культуры микроорганизмов Pseudomonas aeruginosa u Mycobacterlum 1 urn из расчета 20-30 мл на 1 г сухого вещества биопленки биофильтра. Смесь продувают 3-4 ч, потом ее постепенно ввод т в подающий трубопровод и вместе с неочиценной водой равномерно распредел ют по поверхности биофильтра. Пример. Предлагаемый способ апробирован в лабораторных услови х на городских сточных водах, содержа щих нефтепродукты. Сточные воды подавались в лабораторную модель аэрофи тра высотой 3,0 м диаметром .150 мм. Проведены серии опытов без внесени смеси нефтеразрушающих культур и регенерированной биоппенки и с внесением. Результаты очистки приведены в таблице. При внесении смеси нефтеразрушающих культур и регенерированной биопленки эффект очистки по органи- ческим загр знени м ХПК (химической потребности в кислороде) и нефтепродуктам значительно увеличиваетс . После внесени смеси количество нефтепродуктов уменьшаетс в 4,4 раза , ХПК - в 2 раза. В био пленке, отобранной с различных горизонтов аэрофильтра, после внесени смеси количество микроорганизмов , окис;7 ющих органические вещества, в том числе нефтеокисл ющих микроорганизмов, увеличилось в несколько сот раз. Сточные воды,, очищенные на аэрофильтре с внесением смеси микроорганизмов с регенерированной биопленкой , могут быть использованы на нужды промыьчленных предпри тий, а также на полив зеленых насаждений без строительства дополнительных дорогосто щих сооружений по доочистке биохимически очищенных сточных вод.(54) METHOD FOR CLEANING WASTEWATER FROM ORGANIC. . SUBSTANCES, PRIORESTICALLY OIL-CONTAINING A fairly concentrated microbial suspension of each of the cultures is obtained. Twice a month, biofilm deposited in the secondary settling tank is fed into a separately standing tank, and cultures of microorganisms Pseudomonas aeruginosa and Mycobacterlum 1 urn are added to the same volume at a rate of 20-30 ml per 1 g of biofilm dry matter biofilter. The mixture is blown for 3-4 hours, then it is gradually introduced into the supply pipeline and, along with the inadequate water, is evenly distributed over the surface of the biofilter. Example. The proposed method was tested in laboratory conditions on municipal wastewater containing petroleum products. Wastewater was fed to a laboratory model of aerostatic height 3.0 m in diameter .150 mm. Conducted a series of experiments without making a mixture of oil-depleting crops and regenerated biopen and with the introduction. The cleaning results are shown in the table. When a mixture of oil-depleting crops and regenerated biofilm is applied, the cleaning effect on organic pollutants of COD (chemical oxygen demand) and oil products increases significantly. After making the mixture, the amount of oil products decreases 4.4 times, the COD - 2 times. In the biofilm selected from different horizons of the aerofilter, after adding the mixture, the number of microorganisms oxidizing organic substances, including oil-oxidizing microorganisms, increased several hundred times. Wastewater, purified on an aerofilter with the introduction of a mixture of microorganisms with a regenerated biofilm, can be used for the needs of industrial enterprises, as well as for irrigation of greenery without building additional expensive facilities for the purification of biochemically treated wastewater.
