Изобретение относитс к способам биологической очистки сточных вод от органических , соединений, например сточных вод микробиологических производств, и может быть использовано в хилгической, пищевой промышленност х .The invention relates to methods for biological purification of wastewater from organic compounds, for example, wastewater from microbiological production, and can be used in the chemical and food industries.
Известен способ очистки сточных вод от органических загр знений путем обработки зелеными водоросл ми ElJ,- Однако этот способ не может быть дл высококонцентрированных по органике стоков с ХПК до 1О бОО мг/л, так как они обладают высокой мутностью и цветностью, что затрудн ет фотосинтетическую де тельность зеленых водорослей, а следовательно, и их рост . The known method of wastewater treatment from organic pollution by treatment with green alga ElJ, - However, this method cannot be for highly concentrated organic wastewaters with CODs up to 100 mg / l OO, as they have high turbidity and color, which makes photosynthetic difficult. the activity of green algae, and, consequently, their growth.
Кроме того, необходимые дл жизнеде тельности зеленых водорослей биогенные элементы в кондентрированных сточных водах содержатс в труднодоступных формах.In addition, biogenic elements necessary for the life of green algae in the condensed wastewater are contained in hard-to-reach forms.
С целью повышени степени очистки сто ных вод и возможности использовани образующего активного ила в производстве бактериальных препаратов в предлагаемом способе в сточную воду ввод т комплекс сине-зеленых водорослей yauoph taIn order to increase the degree of purification of sewage and the possibility of using active sludge in the production of bacterial preparations in the proposed method, a complex of blue-green algae yauoph ta is introduced into the wastewater.
и бактериальны с культур, обладающих азотфиксирующей способностью, способностью разлагать фосфаты, клетчатку и гуматы, преимущественно Aioiobacter, ClosifLdium, Cvtophaja, Cellvibrio,Pseudomonas 3esmoliticu-m bo-cittus glutinosusЭтот комплекс обладает способностью к росту и развитию в широком диапазоне рН, при высокой, (до 1000О мг/л по ХПК) концентрации органических веществ в среде, снижа ее до 20ОО мг/л и менее, т.е. до значений, допускающих дальнейшую биохимическую очистку активным илом. Указанный комплекс может быть использован как дл обработки сточных вод дефицитных по азоту и легкогидролизуемым формам фосфатов, так и дл обработки сточных вод, сбалансированных по концентрации биогенных элементов, но содержащих трудноокисл емые органические загр знени , например клетчатку и гу- маты. При этом обеспечиваетс саморегулирование концентрации азота и фосфора, рН реды. Образующийс в процессе аэробной биохимической очистки избыточный активный ил по сравнению с исходной жидкостью обогадпен легкогвдролиауемыми формами Органических соединений азота и фосфора, соде1. жиг витамины, ростовые вещества и другие биологически активные соединени . Это позвол ет использовать избыточный активный and bacterial with cultures having nitrogen-fixing ability, ability to decompose phosphates, cellulose and humates, preferably Aioiobacter, ClosifLdium, Cvtophaja, Cellvibrio, Pseudomonas 3esmoliticu-m bo-cittus glutinosusEtot complex is capable of growth and development in a wide pH range, at a high ( to 1000O mg / l COD) the concentration of organic substances in the medium, reducing it to 20OO mg / l or less, i.e. to values that allow further biochemical purification with activated sludge. This complex can be used both for treating wastewaters deficient in nitrogen and easily hydrolyzable forms of phosphates, and for treating wastewaters that are balanced in the concentration of nutrients but contain hardly oxidizable organic pollutants, such as cellulose and gumate. This ensures self-regulation of the concentration of nitrogen and phosphorus, pH pH. Excess activated sludge formed in the process of aerobic biochemical purification, as compared with the initial liquid, is enriched with lightly controlled forms of organic compounds of nitrogen and phosphorus, soe1. Burning vitamins, growth substances and other biologically active compounds. This allows the use of excess active
ил в производстве различных бактериальных препаратов, таких как знтобактерин и р д других инсектишадных препаратов.Sludge in the production of various bacterial preparations, such as zntobakterin and a number of other insecticide drugs.
Дл осуществлени предлагаемого снос о- ба концентрированные сточные воды с содержанием органических загр знений по ХПК до 4-15 г 0 /л соотношением ВПК: ХПК 1:1 - 1:2 инокулируют указанными выше организмами, выращенными на селективньЛх средах. Полученную суспензию организмов культивируют в сточной жидкости в аэробных нестирильных услови х в открытом резервуаре до накоплени максимальной биомассы активного ила.To carry out the proposed demolition, both the concentrated wastewater with the content of organic impurities in the COD up to 4-15 g 0 / l, the MIC: COD ratio 1: 1 - 1: 2 is inoculated with the above organisms grown on selective media. The resulting suspension of organisms is cultured in wastewater under aerobic unsterile conditions in an open tank until the maximum biomass of activated sludge is accumulated.
В дальнейшем обработку сточной жидкости ведут при рециркул ции части нарастающей биомассы, поддержива ее концентрацию до 2-4 г/л. При этом автоматически устанавливают оптимальное соотношение между отдельными микроорганизмами и за 8-17 и достигают снижени загр знений на 80-93%Subsequently, wastewater is treated by recycling part of the growing biomass, maintaining its concentration up to 2-4 g / l. At the same time, the optimal ratio between individual microorganisms and for 8–17 is automatically established and a decrease in contamination by 80–93% is achieved.
Прощедшую обработку сточную жидкость направл ют на канализащюнкые очистные сооружени или используют повторно в микробиологическом производстве дл приготов лени сред.
