Description
Изобретение относитс к области Сиблогической очистки сточных вод и может быть использовано на предпри ти х по переработке сернистых природных газов дл очистки высококонцвитрированных сточных вод, соде жащих диэтанолаьшн. Цель изобретени повьшение степени очистки высококо центрирова ных сточных вод и содержани биомас сы. Пример 1. Обработке подвергают высококонцентрированные диэтанoлa шнcoдepжatqиe сточные воды, образующиес на установках аминовой очистки природного газа от сернисты компонентов газоперерабатывающего завода. Дл вьделени биоценоза микроорганизмов , p.p. Pseudomonas и Bacillus , адаптированных к- диэталамину (ДЭА), активный ил, отобранный из аэрационной зоны биологических очис иых сооружений завода, культивируют на питательной среде, содержащей возрастающие концентрации ДЭА (от 100 до 2000 мг/л), при в течение 216-240 ч (до 10 сут). Дл каждой концентрации ДЭА прои вод т один пассаж, на конечной концентрации (2000 мг/л) выделение био ценоза заканчивают. Таким образом п лучают биоценоз микроорганизмов,спо собных разрушать высокие концентрации ДЗА и устойчивых к другим специ фическим загр знени м стоков произв ства переработки г.ероводородсодержащих газов. Сточную воду нейтрализуют ортофосфорной кислотой до рН 7,5, при этом внос т необходимое количество источника фосфора. Затем высококонцентри рованные дизтаноламинсодержащие стоки развод т условно чистыми промстоками при соотношении 1:Гдо содержани ДЭА на уровне 1000 мг/л. В нейтрализованную сточную воду (объем 5 л) ввод т биоценоз культур p.p. Pseudoraomas и Bacillus в различных количествах (от 0,6 мл до 0,08 мл), что соответствует соотношению биоценоза и сточной воды (1г8000) -. (1S60000). В окситенк (объем рабочей зоны 5,0 л), заполнеиньсй активным илом из очистных сооружений (концентраци 10 г/Лц зольность 28%) подают разбавленную нейтрализованную стйчную воду с добавкой биоценоза, имеющую следующие показатели; ХПК 1100 MrOj/л, БПК„о 150 , В окситенк подают воздух в течение 10 ч с расходом 1. л/ч, что обеспечивает содержание растворенного кислорода в воде не менее мг/л. По истечении tO ч в воде по вл ютс нитраты, нитрить аммонийный азот, что говорит о разложении ДЭА и окончании процесса его окислени . Результаты проведенш-.: исследований приведены з табл.i. /Таблица IThe invention relates to the field of Siblogical wastewater treatment and can be used in sulphide natural gas treatment plants for the purification of highly constituted wastewater containing diethanolysis. The purpose of the invention is to increase the degree of purification of high-centered wastewater and the content of biomass. Example 1. The treatment is subjected to highly concentrated diethanol shneconed waste water generated in the amine purification plants of natural gas from the sulphide of the components of the gas processing plant. For the microbial biocenosis, p.p. Pseudomonas and Bacillus, adapted to diethyl amine (DEA), activated sludge taken from the aeration zone of biological refineries of the plant, are cultured on nutrient medium containing increasing concentrations of DEA (from 100 to 2000 mg / l), for 216-240 h (up to 10 days). For each concentration of DEA, one passage was made; at the final concentration (2000 mg / l), the release of biocenosis was completed. In this way, the biocenosis of microorganisms is obtained that are capable of destroying high concentrations of DZA and resistant to other specific contaminants of the production of hydrogen-containing gases. The wastewater is neutralized with orthophosphoric acid to a pH of 7.5, and the required amount of phosphorus source is introduced. Then, highly concentrated dizthanolamine-containing drains are diluted with conditionally clean industrial effluents at a ratio of 1: where the DEA content is 1000 mg / l. The biocoenosis of p.p. cultures is introduced into neutralized waste water (volume 5 l). Pseudoraomas and Bacillus in different quantities (from 0.6 ml to 0.08 ml), which corresponds to the ratio of biocenosis and wastewater (1y8000) -. (1S60000). Diluted neutralized still water with the addition of a biocenosis with the following parameters is fed to an oxytic bag (the volume of the working zone is 5.0 l), filled with active sludge from treatment plants (concentration 10 g / Lz; ash content 28%); COD 1100 MrOj / l, BOD "about 150, Oxytox serves air for 10 hours with a flow rate of 1. l / h, which ensures that the dissolved oxygen content in water is at least mg / l. After tOh, nitrates appear in water, nitrite ammonium nitrogen, which indicates the decomposition of DEA and the end of the process of its oxidation.

При соотношении $ 1:60000 степень очистки воды от ДЭА недостаточна, прирост биомассы невысок. При соотношении биоценоза микроорганизмов и стоков 1:8000 прирост 10 биомассы по сравнению с соотношением 1:10000 снижаетс , а степень очистки увеличиваетс незначительно на 0,5%, что не оправдьшает добавлени биоценоза в воду в большом 15 количестве.

В табл.3 приведены сравнительные данные по очистке сточных водот ДЭА биоценозом микроорганизмов p.p.Pseudomonas и Bacillus известным и предлагаемым способами.7.1 31269/4 As can be seen from Table 1, the optimal conditions for cleaning waste under deaeration are related to the correlation between the biocenosis of microorganisms and waste water 1: 10,000 - 1: 50,000. With a ratio of $ 1: 60000, the degree of water purification from DEA is insufficient, the biomass increase is not high. When the ratio of microorganism biocenosis and wastewaters is 1: 8000, the growth of 10 biomass decreases in comparison with the ratio of 1: 10,000, and the degree of purification increases slightly by 0.5%, which does not justify adding a biocenosis to water in a large amount of 15. EXAMPLE 2 Purification at various pH values (from 6.8 to 8.0) is subjected to waste water having the following indices: COD 1100, 20 BOD "„. "150 MGO ,, / l. POLY is introduced into drains. the biocenosis of microorganisms at a ratio of 1: 30,000. The conditions of the experiment are the same as in Example 1. The results of the studies are included in Table 2. 9 T a blendsa 2 As can be seen from Table 2, the optimum pH values for maintaining the process are 7.2-7.8, since at smaller and larger values, a decrease in the growth, biomass and protein content is observed her. Table 3 shows the comparative data on the wastewater treatment of DEA by the biocenosis of p.P. Pseudomonas and Bacillus microorganisms by known and proposed methods.
