(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД (54) METHOD FOR CLEANING WASTE WATER
1one
Изобретение относитс к области очистки сточных вод шелкомотгшьного производства и может быть использовано дл очистки стоков от сернци на на предпри ти х по производству натурального шелка..The invention relates to the field of wastewater treatment of silk-yielding production and can be used to clean sewage from sludge on natural silk production plants.
Известен способ очистки сточных вод, содержащих белки.A known method of purification of wastewater containing proteins.
Недостатками способа вл ютс сложность схемы очистки, ее многостадийность , длительность обработки и большой расход реагентов.The disadvantages of the method are the complexity of the purification scheme, its multi-stage character, the duration of the treatment, and the high consumption of reagents.
Наиболее близким к изобретению по технрхческой сущности вл етс способ очистки стоков шелкомотального производства с помощью Добавлени серной кислоты с последующим отделением осадка.The closest to the invention in terms of technology is a method for cleaning wastewaters of silk-melt production by adding sulfuric acid, followed by separation of the precipitate.
При этом степень очистки сточной воды составл ет не более 70%.In this case, the degree of purification of waste water is not more than 70%.
Целью изобретени вл етс повььшение степени очистки воды.The aim of the invention is to increase the degree of water purification.
Поставленна цель достигаетс обработкой воды сол ми трехвалентного железа при рН 2,0-4,5 с последующим отделением осадка,The goal is achieved by treating water with ferric salts at a pH of 2.0-4.5, followed by separation of the precipitate,
Пример. К2л сточной вода с концентрацией серицина 0,5 г/л добавл ют 13 МП 10%-него хлорного железа . Величину рН воды мен ют в преОТ СЕРИЦИНАExample. K2L waste water with a sericin concentration of 0.5 g / l is added 13 MP 10% ferric chloride. The pH of the water changes to SERICINE.
делах от 1 до 5. Выпавший осадок ртдвл йт центрифугированием.affairs from 1 to 5. The precipitated precipitate is centrifuged.
Вьздёлёййес рйЦйка наиболее полно проходит в интервале рН 2,7-3 и составл ет 95% см. таблицу, степень очистки по ХПК 81%. Объем осадка после центрифугировани .по предложенному способу 1-2%.The output of the RyTeSa most fully passes in the pH range 2.7–3 and is 95%. See the table, the degree of purification by COD is 81%. The volume of sediment after centrifugation. According to the proposed method, 1-2%.
В таблице приведены данные о10 степени извлечени серицина из сточных вод в зависимости от рН при дозе FeCtj 650 мг и содержании серидина в исход ной воде 500 мг/л.The table shows data on the 10 degrees of recovery of sericin from wastewater, depending on the pH at a dose of FeCtj of 650 mg and the content of seridin in the source water of 500 mg / l.

Изоэлектрическа точка дл сери30 дина находитс в области рН 3,8-4,2,The isoelectric point for serine dyne is in the pH range of 3.8-4.2,
однако наибольша степень выделени данного белка с помс цью хлорного , железа наблюдаетс при более низких рН. доза железадл выделени серицина мен :етс в зависимости от исходной концентрации белка Поэтому необходимо устанавливать эквивалентное количество железа дл выделени серицина путем турбодиметрического. титровани .however, the greatest degree of excretion of this protein with respect to chlorine and iron is observed at lower pH. The dose of iron for sericin release varies depending on the initial protein concentration. Therefore, it is necessary to establish an equivalent amount of iron for the production of sericin by turbodimetric. titration

Преимуществом предложенного спосо ба по сравнению с известным способом ёьщелени белков вл етс повышение степени очистки, сокращение ее времени , что ведет к уменьшению капитальных затрат при строительстве и эксплуатации очистных сооружений. Вода после отделени серицина может быть использована повторно дл обработки коконов.The advantage of the proposed method in comparison with the known method of protein bifida is an increase in the degree of purification, a reduction in its time, which leads to a decrease in capital expenditures during the construction and operation of sewage treatment plants. The water after separation of sericin can be reused to treat the cocoons.
