Abstract
The invention discloses a kind of deep treatment method for removing industrial wastewater mineral oil in fluid, waste water inhales reactor, primary sedimentation basin, pH value regulating reservoir, aeration nitrification tank, biological denitrificaion pond, secondary sedimentation tank, water purifying tank processing by sump, coarse rack, microvesicle air supporting mineral oil adsorbent equipment, mineral oil catalysis again neutralizing successively.This method creativeness make use of catalytic action of the π allyl Ni compounds to mineral oil molecule, when the mineral oil in waste water is modified kieselguhr adsorption and at a temperature of 200 ~ 250 DEG C, under the catalysis of π allyl Ni compounds, of short duration fracture can occur for the C H keys in mineral oil molecule, and quickly in conjunction with for C C keys or C H keys, and C H keys can be broken again, C C keys are then limited without being broken again because of the catalytic action of π allyl Ni compounds, therefore the mineral oil molecule that carbochain can be made shorter gradually synthesizes the longer heavy oil molecules of carbochain.
Description
Technical field
The present invention relates to one kind to remove industrial wastewater Minerals oil treatment process, the wastewater treatment belonged in environmental protection
Field.
Background technology
Along with the fast-developing of China's economy and energy demand is continuously increased, the application of mineral oil is continuous
Expand, consumption also increases increasingly.During crude oil production, processing, transport and a large amount of uses of various refining oil, by
In the limitation of technological level and treatment technology, largely the waste water containing mineral oil, waste residue are inevitably discharged into water body, produce therewith
Problem of environmental pollution it is also increasingly severe.A large amount of presence of the mineral oil in water body environment can cause sternly to water ecosystem
The harm of weight, and the quality of water body oily pollution issue handling is directly connected to the sustainable development of natural ecological environment and economy.
Mineral oil typically can enter human body by approach such as breathing, skin contact, the edible foods containing pollutant, can shadow
The normal function of a variety of organs of human body is rung, triggers a variety of diseases.By the areas adjacent of mineral oil stain, child skin alkali drag
Obvious decrease, leucocyte decline, anemia rate rises, PFT is affected, and the swollen probability of liver of common people is significantly higher than check plot
Resident, malignant tumour especially alimentary system malignant tumour standardization mortality rate is apparently higher than check plot.The concentration of mineral oil is to examine
The key factor of its toxicity is examined, its toxic effect of the mineral oil of different component is also different, rise and open-assembly time with concentration
Extension, its toxicity enhancing.
After pollutant mineral oil enters water body, in the presence of the factors such as environmental condition, its composition and property and existence form
It will be varied from.In general, pollutant mineral oil is mainly with floating oil, dispersed oil, oil emulsion, dissolved oil, oil-solids
It is present in Deng 5 kinds of states in water.Different types of oil-polluted water will use different processing methods, contain mineral oil both at home and abroad at present
The treatment technology of sewage can be divided into 4 kinds by handling principle：Physical, chemical method, physical-chemical process and biochemical process.
（1）Physical：
The emphasis of physical treatment process is mineral matter and most of solid suspension, oil in removal oily water containing mineral etc..Including
The methods of Gravity Separation, centrifugation, coarse, filtering, UF membrane.
（2）Chemical method：
Method of chemical treatment is mainly for the treatment of individually can not be removed in oily water containing mineral with physical method or biological method one
Part colloid and dissolved matter, conventional method have chemical demulsification method, chemical oxidization method etc..
（3）Physical-chemical process：
Physical-chemical process mainly includes Bubble-floating Method, absorption method, electrochemical process, ultrasonic separation method etc., and these methods typically all have
There is the advantages of adaptability is relatively strong, selectivity is wide.
（4）Biochemical process：
