Description
;о;about
00 i 11980 Изобретение относитс к способам очистки сточных вод и может быть йспользовано при очистке сточных вод гидролизной промышленности. Цель изобретени - повышение сте-s пени очистки от лигногуминового Kotrплекса . Очистку последрожжевой бражки ществл ют следующим образом. Иммобилизованную полифенолоксида- Ю зу готов т смешением поливинилспир- тового волокна, ацеталированно о таровым диальдегидом, с 0,2%-ным раствором препарата полифенолоксидазы из базидиомицетов, выдерживают при коьг-15 иатной температуре в течение I ч. По окончании реакции раствор отдел - ют, волокно промывают водой. Количество сорбированной полифенолоксидазы определ ют спектрофотомётрически.20 Иммобилизованную полифенолоксидазу 2I в количестве мг ввод т в 1 л . последрожжевой бражки с рН А,,0, Смесь выдерживают при температуре 30 С и вращении на ротационной качалке в течение i-i ч. Степень очисткк последрожжевой бражки оценивают по содержанию в ней лигногуминовых j веществ и изменению ее цветности, Количество лигногуминового комплек са в последрожжевой бражке определ ют на спектрофотометре, цветность на приборе Specoi. Приме р..Способ осуществл ют при характеристике исходной бражки, котора содержит: цветность 0 ,в усл.ед.; химическое потребление кислорода (ХПК) - 7700 мг лиг ногуминовый комплекс (ЛГК) 1160 мг/л. Результаты очистки представлены в табл. 1, Таблица 100 i 11980 The invention relates to wastewater treatment methods and can be used in wastewater treatment of the hydrolysis industry. The purpose of the invention is to increase the ste-s stumps of purification from the ligno-humic Kot-complex. Post-yeast cleaning is implemented as follows. The immobilized polyphenol oxide-Uz is prepared by mixing polyvinyl alcohol fiber, acetalized with tare dialdehyde, with a 0.2% solution of the basidiomycetes polyphenol oxidase preparation, kept at a coagent-15 temperature of I h. I h. After the reaction, the solution is separated. the fiber is washed with water. The amount of sorbed polyphenol oxidase is determined spectrophotometrically. 20 Immobilized polyphenol oxidase 2I in the amount of mg is introduced per liter. The post-yeast brew with pH A ,, 0, the Mixture is maintained at a temperature of 30 ° C and rotated on a rotary shaker for ii h. The degree of purification of the post-brew brew is assessed by the content of lignohumine j substances in it and the change in its chromaticity. The amount of lignohumic complex in the post-yeast brew is determined are on the spectrophotometer, the color on the device Specoi. Example .. The method is carried out with the characteristic of an initial beer, which contains: chromaticity 0, in conventional units; chemical oxygen consumption (COD) - 7700 mg leagues of the nogumin complex (LGK) 1160 mg / l. The cleaning results are presented in table. 1, Table 1
