Известен способ приготовлени питательной среды дл выращивани хлореллы, включающий обработку сточных вод свинарников путем аэрировани . Сточные воды свинарников выдерживают при 25°С 60 дней в услови х брожени , затем аэрируют и после отстаивани осветленную часть разбавл ют дес тикратным объемом водопроводной воды.There is a known method for preparing a culture medium for growing chlorella, which includes the treatment of pigs wastewater by aeration. The waste waters of the pig houses are kept at 25 ° C for 60 days under fermentation conditions, then aerated and, after settling, the clarified part is diluted with ten times the volume of tap water.
С целью ускорени процесса приготовлени питательной среды сточные воды свинарников раздел ют на твердую и жидкую фракции, причем жидкую фракцию аэрируют в циркул ционно-окислительном канале в течение семи - дев ти суток при 22-25°С, а затем подвергают минерализации на пластинчатом фильтре до снижени значени 350 мг Ог/л.In order to speed up the preparation of the nutrient medium, the pigs wastewater is divided into solid and liquid fractions, the liquid fraction being aerated in the circulation and oxidation channel for seven to nine days at 22-25 ° C, and then subjected to salinity on a plate filter reduction of 350 mg Og / l.
Пример. Сточные воды от свинарников раздел ют на центробежном фильтре на твердую и жидкую фракции. Жидкую фракцию с тыс мг 02/л подвергают аэрации в циркул ционно-окислительном канале доExample. Wastewater from the pig houses is divided into a solid and a liquid fraction on a centrifugal filter. The liquid fraction from thousand mg 02 / l is subjected to aeration in the circulation and oxidation channel to
значени ,3 тыс. мг О2/л, затем обрабатывают на пластинчатом биофильтре, где БПКз снижаетс до 300 мг О2/л. Обработанные таким способом стоки используют как питательную среду дл выращивани хлореллы . Выход биомассы составл ет 2,2 г/л абсолютно сухого вещества.values, 3 thousand mg O2 / l, then treated on a plate biofilter, where the BODC is reduced to 300 mg O2 / l. Waste treated in this way is used as a nutrient medium for growing chlorella. The biomass yield is 2.2 g / l of absolutely dry matter.
