(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ НЕФТЕПРОДУКТОВ И МАСЕЛ(54) METHOD FOR CLEANING WASTE WATER FROM PETROLEUM PRODUCTS AND OILS
Изобретение относитс к способам очистки сточных вод от нефтепродуктов, масел и других органических веществ и может найти применение в нефтеперерабатывающей , нефтехимической и химической промышленности.The invention relates to methods of treating wastewater from petroleum products, oils and other organic substances and may find application in the refining, petrochemical and chemical industries.
Известны различные способы очистки сточных вод нефтеперерабатывающих заводов , например, с помощью порошкообразного активного угл 1. После контакта со сточной водой уголь отдел ют осаждением. Дл улучшени осаждени добавл ют коагул нты и флокул нты.Various methods are known for treating wastewater from refineries, for example, using powdered active carbon 1. After contact with waste water, the coal is separated by sedimentation. Coagulants and flocculants are added to improve the precipitation.
Известен также способ очистки сточных вод от нефтепродуктов флокул цией и флотацией 2. Сточную воду в этом способе обрабатывают флокул нтом и осветл ют во флотаторе. 5-20% осветленной воды, по . лученной в камере флотации, насыщают воздухом и вновь подают во флотационную камеру.Also known is a method for purifying waste water from oil products by flocculation and flotation 2. In this method, wastewater is treated with flocculation and clarified in a flotation device. 5-20% clarified water, by. radiated in the flotation chamber, saturated with air and re-fed into the flotation cell.
Однако эти способы не позвол ют достичь высокой степени очистки сточных вод (степень удалени загр знений составл ет 80-85%).However, these methods do not allow to achieve a high degree of wastewater treatment (the degree of contamination removal is 80-85%).
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ очистки нефтьсодержащих сточных вод пенной флотациейThe closest to the invention to the technical essence and the achieved result is a method of cleaning oil-containing wastewater froth flotation
; в присутствии поверхностно-активных веществ (ПАВ) и адсорбента - порощкообразного угл 3.; in the presence of surface-active substances (surfactants) and adsorbent - powdered coal 3.
Недостатками способа вл ютс большой расход активного угл (1200- 5 1600 мг/л) и недостаточно высока степень очистки сточных вод, что объ сн етс низкой степенью удалени порошкообразного активного угл , так как в очищенной воде остаетс до 5% взвешенных частиц неот10 флотированного угл .The disadvantages of this method are the high consumption of active carbon (1200-5 1600 mg / l) and the insufficiently high degree of wastewater treatment, which is explained by the low degree of removal of powdered active carbon, since up to 5% of suspended particles of non-flooded carbon remain in purified water. .
Кроме того, введение в сточную воду ПАВ загр зн ет очищенную воду, так как адсорбционна емкость порошкообразного активного угл (ПАУ) по отношению кIn addition, the introduction of surfactant into wastewater contaminates purified water, since the adsorption capacity of powdered active carbon (PAH) with respect to
15 ПАВ составл ет неполную долю их предельного адсорбционного объема. Так, например дл некоторых ПАВ их адсорбци на ПАУ осуществл етс до остаточной концентрации , равной 0,5-2,5 мг/л.15 surfactants comprise an incomplete fraction of their limiting adsorption volume. For example, for some surfactants, their adsorption on PAHs is carried out to a residual concentration of 0.5-2.5 mg / l.
20 Целью изобретени вл етс сокращение расхода порошкообразного активного угл и повышение степени очистки сточных вод.20 The aim of the invention is to reduce the consumption of powdered activated carbon and increase the degree of wastewater treatment.
2- Дл этого сточную воду обрабатывают коагул нтом и флокул нтом, флотируют и часть очищенной флотацией сточной воды (предпочтительно 20-100% от объема очищаемой сточной воды), после контакта2- For this, wastewater is treated with coagulant and flocculant, and flotation of a part of the treated wastewater by flotation (preferably 20-100% of the volume of treated wastewater), after contact
