Изобретение относитс к области очистки промышленных сточных вод рыбокомбинатов, обрабатывающих рыбу и вырабатывающих рыбокоисервы, пресервы и рыбную муку; оно может быть использовано при утилизации побочных продуктов.The invention relates to the field of purification of industrial wastewater from fish factories that process fish and produce fish preserves, preserves and fish meal; It can be used in the disposal of by-products.
По основному авт. св. № 457668 известен способ очистки сточных вод рыбоконсервных комбинатов от органических соединений и питательных веществ. По этому способу флотирование осуществл ют раздельно дл жирсодержащих и жир-белоксодержащих стоков, полученные продукты смещивают с отходами жира от технологического процесса и с концентрированным активным илом, а смесь подвергают гомогенизации и пастеризации. Однако известный способ не решает проблему утилизации нобочных продуктов прн выработке рыбной муки.According to the main author. St. No. 457668 discloses a method for the purification of waste waters of fish canning plants from organic compounds and nutrients. In this method, the flotation is carried out separately for fat-containing and fat-protein-containing effluents, the products obtained are shifted with waste fat from the process and with concentrated activated sludge, and the mixture is subjected to homogenization and pasteurization. However, the known method does not solve the problem of utilization of nocturnal products for the production of fish meal.
Целью изобретени вл етс выделение из стоков побочных продуктов и отходов производства . Это достигаетс тем, что полученные после флотации продукты перед смещиванием с концентрированным активным илом сепарируют преимущественно при 60-70 С дл выделени жира, а сепарат в смеси с рыбным соком от технологических процессов производства выпаривают в две стадии соответственно при 60-65°С на первой стадии и 55- 60°С на второйThe aim of the invention is the isolation of by-products and waste from the effluent. This is achieved by separating the products obtained after flotation prior to displacement with concentrated active sludge mainly at 60-70 ° C to release fat, and separate it from the technological processes of production in mixture with fish juice at 60-65 ° C at the first stage. stages and 55-60 ° C at the second
