Description
(54) КОАГУЛЯНТ ДЛЯ ОЧИСТКИ СТОЧНЫХ ВОД(54) COAGULANT FOR SEWAGE TREATMENT
В качестве реагента д.л . очистки стоков красильно-отделочных производств используют серицин, содержащийс в отходах шелкомотального производства.As a reagent d. The wastewater treatment of the dyeing and finishing facilities uses sericin contained in the waste of silk and cotton production.
Технологи способа заключаетс в добавлении водного раствора серицина 0,1%-1ной концентрации к сточным водам красильноотделочных производств в количест|ве эквивалентном концентрации загр знений (при рН в интервале 2,0-4,5);The process technology consists in adding an aqueous solution of sericin at a concentration of 0.1% -1% to the wastewater of the dyeing industry in an amount equivalent to the concentration of contaminants (at a pH in the range of 2.0-4.5);
В случае, если стоки наход тс поблизости , то очистку целесообразно вести смешением стоков в эквивалентных соотношени х , необходимых дл коагул ции красител .In the event that the drains are nearby, it is advisable to clean up by mixing the effluent in equivalent ratios necessary for the coagulation of the dye.
Пример 1. Готов т 10%-ный раствор серицина из осадка, полученного при обработке сточных вод шелкомотального Производства IB 0,1%-ной серной кислоте. К 1 л сточных вод красильно-отделочного производства шелковой промышленности с концентрацией красителей 100 мг/л добавл ют при перемешивании 2,мл 10%-ного раствора серицина. Выпавший осадок отдел ют от воды фильтрованием.Example 1. A 10% solution of sericin is prepared from the sludge obtained by treating the wastewater of Silkomotal Production IB with 0.1% sulfuric acid. To 1 liter of wastewater of the dyeing and finishing production of the silk industry with a dye concentration of 100 mg / l, 2, ml of 10% sericin solution are added with stirring. The precipitate formed is separated from the water by filtration.
Количество образующегос осадка составл ет 1-3% от объема обрабатываемыхThe amount of precipitate formed is 1-3% of the volume processed
сточных вод в зависимости от «концентрации загр знении. Степень очистки 85%.wastewater depending on the concentration of contamination. The degree of purification is 85%.
Пример 2. 1 л сточной воды шелкОМотальнОГо производства, содержащего серицин в количестве 0,5 г/л, добавл ют к 2,5 л сточной воды с содержанием красителей около 100 мг/л, подкисленной до рН 3,0. Выпавший осадок отфильтровывают.Example 2. 1 liter of silk-made wastewater containing 0.5 g / l of sericin is added to 2.5 l of wastewater with a dye content of about 100 mg / l acidified to a pH of 3.0. The precipitate is filtered off.
Степень очистки, как в примере 1.The degree of purification, as in example 1.
К преимуществам Предложенного способа относитс удешевление процесса очистки сточных вод.The advantages of the proposed method include the cheaper process of wastewater treatment.
