( СПОСОБ БИОХИМИЧЕСКОЙ очистки сточных вод(METHOD OF BIOCHEMICAL sewage treatment
от ФЕНОЛОВfrom phenols
1one
Изобретение относитс к способам биохимической очистки сточных вод от фенольных соединений и может найти применение при очистке сточных вод предпри тий целлюлозно-бумажной, нефте- и углехимической промышленности.The invention relates to methods for the biochemical treatment of wastewater from phenolic compounds and may find application in the treatment of wastewater from pulp and paper, petrochemical and coal chemical industries.
Известен способ биохимической / очистки сточных вод путем окислени комплексом термофильных плесневых грибов из рода Aspergillus. Процесс ведут при 55-70 С, рН среды 6,58 ,0 1.There is a method of biochemical / wastewater treatment by oxidation with a complex of thermophilic mold fungi from the genus Aspergillus. The process is carried out at 55-70 C, pH of 6.58, 0 1.
Известен т.акже способ очистки сточных вод путем введени в сточные воды грибов из рода РепiciIlium sp. в чистой культуре или в смеси с Aspergi 1 lus sp. 2 .Also known is the method of wastewater treatment by introducing fungi of the genus RepiciIlium sp. Into wastewater. in pure culture or mixed with Aspergi 1 lus sp. 2
Недостатком этих способов вл етс сложность процесса очистки ввиду необходимости подогрева сточных вод.The disadvantage of these methods is the complexity of the cleaning process due to the need to heat the wastewater.
Наиболее близким по технической сущности и достигаемому результату к предлагаемому вл етс способ био логического разложени растворов.The closest in technical essence and the achieved result to the proposed is the method of biological decomposition of solutions.
содержащих до 3 г/л фенолов, с помощью штамма Nocardia sp В 87- Штамп используют в виде порошка высушенных оживл емых клеток дл обсеменени очистных сооружений 3Jcontaining up to 3 g / l of phenols, using strain Nocardia sp B 87-A stamp is used in the form of a powder of dried animated cells for seeding treatment plants 3J
Недостатком известного способа вл етс сложность приготовлени порошков высушенных оживл емых клеток . Необходимость подготовки порошков значительно усложн ет способ A disadvantage of the known method is the difficulty of preparing powders of dried, revitalized cells. The need to prepare powders significantly complicates the process.
10 очистки, особенно больших потоков вод.10 purification, especially large streams of water.
Цель изобретени - упрощение и удешевление процесса очистки сточных вод от фенолов.The purpose of the invention is to simplify and cheapen the process of wastewater purification from phenols.

Поставленна цель достигаетс тем что в сточные воды ввод т грибы Botrytis cinerea и Phytophtora infestans и выдерживают в течение времени.The goal is achieved by the fact that Botrytis cinerea and Phytophtora infestans mushrooms are introduced into wastewater and kept for a time.
2020
Источником этих грибов может служить сера гниль, поражающ а овощи.The source of these mushrooms can serve as sulfur rot, affecting vegetables.
Очистку ведут при рН в течение 1-3 сут.Purification is carried out at a pH of 1-3 days.
Способ осуществл ют следующим образом .The method is carried out as follows.
В сточную воду ввод т взвесь гни лых овощей, содержащую мицеллий грибов Botrytis cinerea или Phytophtora infestans, и перемешивают. Через сут воду фильтруют, дл освобождени ее от взвеси,A suspension of rotten vegetables containing the mycelium of the fungus Botrytis cinerea or Phytophtora infestans is introduced into the wastewater and mixed. After one day, the water is filtered to release it from the suspension,
Пример 1. В 250 мл сточной воды, содержащей м фенолов (пирокатехин, гидрохинонТ, ввод т взвесь гнилых овощей из расмета 5 г мицели Botrytfs cinerea на 250 г воды, перемешивают. После трех суток очистки воду фильтруют. Степень очистки сточной воды от пирокатехина 90, от гидрохинона . /Example 1. In 250 ml of wastewater containing m of phenols (pyrocatechin, hydroquinone T, a suspension of rotten vegetables is injected from an estimated 5 g of Botrytfs cinerea mycelium per 250 g of water, stirred. After three days of purification, the water is filtered. The degree of purification of waste water from pyrocatechin 90 from hydroquinone. /
Пример 2. Способ осуществл ют в-услови х примера 1, но ввод т мицелий грибов Phytophtora infestans Степень очистки воды от пирокатехина 99%, гидрохинона 90.Example 2. The method is carried out under the conditions of Example 1, but the mycelium of the fungi Phytophtora infestans is introduced. The degree of water purification from pyrocatechin 99%, hydroquinone 90.
Предлагаемый способ позвол ет производить эффективную очистку сточных вод от фенольных соединений. Кроме того, он значительно упрощает процесс так как не требует предварительной подготовки порошков высушенных оживл емых клеток дл очистки воды, а также делает его более деше вым.The proposed method allows for the efficient treatment of wastewater from phenolic compounds. In addition, it greatly simplifies the process, since it does not require the preliminary preparation of powders of dried, revitalized cells for water purification, and also makes it cheaper.
