Изобретение относитс к способам очистки сточных вод и может быть иснользоваио дл очистки сточных вод цехов гальванических нокрытнй.The invention relates to wastewater treatment methods and can be used to clean wastewater from galvanized shops.
Известен снособ очистки сточных вод после травлени медных и бронзовых изделий, содержащих нерсульфат аммони и медь, обработкой едким натром до рН 12 при 100°С. Известен способ очистки сточных вод от меди обработкой известью но схеме усреднитель - смеситель - камера реакции - отстойник . В очищенной воде меди содержалось до 1 мг/л. Однако известными способами не достигаетс достаточна степень очистки от меди.A known wastewater treatment detachment after pickling copper and bronze products containing ammonium nersulfate and copper, is treated with caustic soda to pH 12 at 100 ° C. A known method of purification of wastewater from copper by treatment with lime but the scheme averager - mixer - reaction chamber - sump. In purified copper water contained up to 1 mg / l. However, a sufficient degree of purification from copper is not achieved by known methods.
Известен способ очистки сточных вод от меди осаждением щелочью при рН 8-10, остаточна концентраци иоиов меди составл ет 0,1-0,15 мг/л и осаждение меди происходит через 15 мин.The known method of purification of wastewater from copper by precipitation with alkali at pH 8-10, the residual concentration of copper ions is 0.1-0.15 mg / l and copper is deposited after 15 minutes.
С целью ускорени процесса и повыщени степени очистки осаждеиие провод т в присутствии натриевой соли мопохлоруксусной кислоты, добавл емой в количестве 0,3- 0,7 мг на 1 мг меди, содержащейс в воде. При этом образуетс быстрооседающий и легкоотделимый осадок. Степень очистки предлагаемым способом составл ет 100% и осаждение меди происходит через 5 мин.In order to speed up the process and increase the degree of purification, the precipitation is carried out in the presence of sodium salt of mopochloroacetic acid added in an amount of 0.3-0.7 mg per 1 mg of copper contained in water. This forms a fast settling and easily separable sediment. The degree of purification by the proposed method is 100% and copper is deposited after 5 minutes.
Пример 1. 300 мл сточной воды нроизводства трихлорфенол та меди, содержащей 300 мг/л меди, смешивают с 3 мл 1%-ного щелочного раствора натриевой соли монохлоруксусиой кислоты. Образовавшийс осадок отстаивают в течение 15 мин и отфильтровывают . В полученном фильтрате медь отсутствует .Example 1. 300 ml of waste water from the production of trichlorophenol copper containing 300 mg / l of copper is mixed with 3 ml of a 1% alkaline solution of sodium salt of monochloroacetic acid. The precipitate formed is allowed to settle for 15 minutes and is filtered off. In the resulting filtrate copper is missing.
Пример 2. 1000 мл сточной воды, содержащей 50 мг/л меди, обрабатывают 1,5 млExample 2. 1000 ml of waste water containing 50 mg / l of copper is treated with 1.5 ml
1%-ного щелочного раствора натриевой соли монохлоруксусной кислоты. Образовавшийс осадок отстаивают в течение 30 мин и отфильтровывают . Медь в фильтрате отсутствует .1% alkaline solution of sodium salt of monochloracetic acid. The precipitate formed is settled for 30 minutes and filtered off. Copper in the filtrate is missing.
Пример 3. К раствору хлорной меди с концентрацией 5000 мг/л добавл ют щелочной раствор 10%-ной натриевой соли монохлоруксусной кислоты в количестве 4,5 мл. Полученный осадок отстаивают в течеииеExample 3. To a solution of copper chloride with a concentration of 5000 mg / l, an alkaline solution of 10% sodium salt of monochloroacetic acid is added in an amount of 4.5 ml. The precipitate is defended in the course of
15 мин и отфильтровывают. Медь в фильтрате отсутствует.15 min and filtered. Copper in the filtrate is missing.
