Изобретение относитс к способам очистки сточных ВОД от фенольных соединений. Этот способ может быть рекомендован как стади доочистки после комплексной очистки сточных вод предпри тий химической, коксохимической промышленности.This invention relates to methods for treating waste HATS from phenolic compounds. This method can be recommended as an aftertreatment stage after complex wastewater treatment of chemical and coke industry enterprises.
Известен Способ очистки сточных вод от органических соединений, в частности от фенольных соединений, водными растени ми, например камышом озерным (Scirpus lacustis) 1.A known method for purification of wastewater from organic compounds, in particular from phenolic compounds, is by aquatic plants, for example, lake reeds (Scirpus lacustis) 1.
Недостатком данного способа вл етс сравнительно невысока степень очистки от фенольных соединений, наход щихс в стоках в малых копцентрапи х ().The disadvantage of this method is the relatively low degree of purification from phenolic compounds that are in the effluent in small centers ().
С -целью Повышени степени очистки и удешевлени процесса предлагаетс в .качестве водных растений при очистке сточных вод от фенольных соединений использовать харовые водоросли.With the goal of increasing the degree of purification and cheapening of the process, it is proposed to use char algae in the quality of aquatic plants in the treatment of wastewater from phenolic compounds.
Харовые водоросли в отличие от других водных растений, которые поглошатот коМПоненты стоков, характеризуютс наличием активной фенолоксидазы, локализованной на поверхности клеток, и могут о.кисл ть фенолы до хинонов, которые легко подвергаютс дальнейшим превращени м до гуминовых кислот (нетоксичные соединени ).Chara algae, unlike other aquatic plants, which absorbed the waste components, are characterized by the presence of active phenol oxidase, localized on the cell surface, and can oxidize phenols to quinones, which are easily subjected to further transformations to humic acids (non-toxic compounds).
Нар ду с окислительными превращени ми возможно накопление |фенолов в водоросл х.Along with oxidative transformations, accumulation of | phenols in algae is possible.
Проведение процесса с харовыми водоросл ми позвол ет извлекать из сточных вод как относительно высокие, так и очень низкие концентрации фенолов (10-1 м:г/л). Степень очистки достигает 80-90%.Carrying out the process with char algae makes it possible to extract both relatively high and very low concentrations of phenols (10-1 m: g / l) from wastewater. The degree of purification reaches 80-90%.
Пример. В сточную воду, содержащую от I ДО 10 МГ/л фенолов, помещают харовые -водоросли из расчета 10 г (сырой вес) на I л раствора. Степень очистки от фенолов за двоеExample. In the waste water containing from I to 10 MG / l of phenols, put char-algae at the rate of 10 g (wet weight) per I liter of solution. The degree of purification from phenols for two
суток достигает 80-90%. Содержание монофенола в воде уменьшаетс на 85%, пи1рокатехина - на 95%.days reaches 80-90%. The content of monophenol in water is reduced by 85%, and that of pyrocatechin by 95%.
Применение харовых водорослей дл доочистки стоков требует незначительных затрат,The use of chara algae for the final treatment of wastewaters requires a small amount of
водоросли необходимо высадить в районе выброса стоков или создать дополнительные промежуточные пруды с посадками водорослей.algae should be planted in the area of discharge of wastewater or create additional intermediate ponds with algae plantings.
