Description

Изсбретение относитс  к способам очистки сточных вод, содержащих органически примеси, например лигнины} лигносульфона ты, протеины. Известен способ очистки сточных вод, содержащих органические примеси, наприме азокрасители, заключающийс  в том, что стоки подвергают облучению V -лучами, а выделившийс  осадок отдел ют, Способ позБол ет тгри исходном содержаНИИ примесей (ХПК) стоков 485 мг О / и дозе облучени  2,6 Мрад достичь 60%- ной степени очистки. О целью повышени  степени очистки сто ных вод перед облучением в очищаемые сточные воды ввод т мономер, например м тилметакрилат, в количестве 0,25-1%. В процессе очистки мономер под действием облучени  V -лучами полимеризуетс  и вьшадает в виде осадка, который, осажда сь , захватьюает органические примеси и вьюодит их из очищаемой воды, Опособ позвол ет при исходном ХПК стоков 800 мг/О /л и дозе облучени  0,01 Мрад достичь 90°о-ной степени оч1:ст ки. Вода после очистки не приобретает никакой наведенной активности и может употребл тьс  дл  производственных нужд, а после специальной обработки и дл  питьевых целей. Удаление кислорода и снижение рН раствора интенсифицирует процесс очистки и улучщает фильтруемость образующегос  осадка. Стои.ость радиационной очистки с введением в очищаемую воду мономера определ етс  стоимостью дозы излучени , необходимой дл  ее осуществлени . Пример, Облучению v -лучами подвергают черный сток сульфат-целлюлозного производства с исходным ХПК 8ОО мг О /л. Перед облучением в сточные аоды ввод т мономер, например метилметакрилат, в количестве 0,25-1%, Облучаютс  пробы в закрытых стекл нных сосудах. Мощность дозы 3 рад/сек, врем  облучени  от 30 до 60 мин. 469 3 Содержание примесей (ХПК) в оставшейс  воде определ ют фильтрованием после отделени  выпавшего осадка Степень очистки 70-90%« изобретени  1. Способ очистки сточных вод, содержащик органические примеси, ионизирующим облучением У -лучами, отличаюшийс   тем, что, с целью очистки стоков, содержащих лигнины, лигносульфонаты, протеины , в последние перед облучением ввод т мономер, например метилметакрилат. 2. Способ по п. 1, о т л и ч а ю ш и йс   тем, что мономер ввод т в количестве 0,25-1%.The exclusion refers to methods of treating wastewater containing organically impurities, such as lignins} lignosulfones, proteins. A known method of treating wastewater containing organic impurities, such as azo dyes, is that the wastewaters are irradiated with V rays, and the precipitated sediment is separated. , 6 Mrad to achieve 60% purity. For the purpose of increasing the degree of purification of wastewater before irradiation, monomer, for example methyl methacrylate, is introduced into the wastewater being treated in an amount of 0.25-1%. During the purification process, the monomer undergoes polymerization under the action of irradiation with V-rays and precipitates as a precipitate, which precipitates, captures organic impurities and removes them from the water being purified. 01 Mrad to reach 90 ° of the -th degree och1: st ki. Water after purification does not acquire any induced activity and can be used for industrial needs, and after special treatment and for drinking purposes. Removing oxygen and lowering the pH of the solution intensifies the cleaning process and improves the filterability of the resulting precipitate. The cost of radiation cleaning with the introduction of monomer into the water to be purified is determined by the cost of the radiation dose required for its implementation. Example, Irradiation of v-rays is subjected to black stock sulfate-cellulose production with the original COD 8OO mg O / l. Prior to irradiation, monomer, for example methyl methacrylate, is introduced into wastewaters in an amount of 0.25-1%. Samples in closed glass vessels are irradiated. A dose rate of 3 rad / s, an irradiation time of 30 to 60 minutes. 469 3 Content of impurities (COD) in the remaining water is determined by filtration after separation of the precipitated sediment effluent containing lignins, lignosulfonates, proteins, monomer, for example methyl methacrylate, is introduced into the latter before irradiation. 2. A method according to claim 1, in which the monomer is introduced in an amount of 0.25-1%.
