Abstract
The invention discloses an advanced treatment method for removing mineral oil in industrial waste water. The waste water is sequentially treated by a water collecting well, a coarse screen, a micro-bubble air floatation mineral oil adsorbing device, a mineral oil catalytic heavy desorption device, a primary sedimentation basin, a pH value adjusting tank, an aerated nitrification tank, a biological denitrification tank, a secondary sedimentation basin, and a water purification tank. According to the method disclosed by the invention, the catalytic action of pi-allyl nickel compound on mineral oil molecules is creatively utilized, and when the mineral oil in the waste water is adsorbed by modified diatomite and is at a temperature of 200-250 DEG C, under the catalysis of the pi-allyl nickel compound, the C-H bond in the mineral oil molecules can generate transitory breakage and then is quickly rebonded into a C-C bond or C-H bond, however, the C-H bond can be broken again, and the C-C bond cannot be broken again due to limited catalytic action of the pi-allyl nickel compound, so that the mineral oil molecules with relatively short carbon chains can be gradually synthesized into heavy oil molecules with relatively long carbon chains.
Description
Technical field
The present invention relates to a kind of deep treatment method removing trade effluent mineral oil in fluid, belong to the field of waste water treatment in environment protection.
Background technology
Fast development along with China's economy and the continuous increase to energy demand, the range of application of mineral oil is in continuous expansion, and consumption also increases increasingly.In a large amount of use procedures of crude oil production, processing, transport and various refining oil, due to the restriction of state of the art and treatment technology, a large amount of waste water containing mineral oil, waste residue inevitably enter water body, and the problem of environmental pollution thereupon produced is also more and more serious.The a large amount of existence of mineral oil in water body environment can cause serious harm to water ecosystem, and the quality of water body oil pollution issue handling is directly connected to the sustainable development of natural ecological environment and economy.
Mineral oil generally can enter human body by approach such as breathing, skin contact, the edible foods containing pollutent, can affect the normal function of the multiple organ of human body, cause various diseases.By the areas adjacent of mineral oil stain, child skin alkali drag obviously weakens, leukopenia, anemia rate rise, pulmonary function is affected, the liver of the common people probability that swells is significantly higher than check plot resident, malignant tumour especially alimentary system malignant tumour standardization mortality rate apparently higher than check plot.The concentration of mineral oil investigates the key factor of its toxicity, and its toxic effect of the mineral oil of different components is also different, and with the rising of concentration and the prolongation of open-assembly time, its toxicity strengthens.
After pollutant mineral oil enters water body, under the effect of the factors such as envrionment conditions, its composition and property and existence form all can change to some extent.In general, pollutant mineral oil is mainly present in water with 5 kinds of states such as floating oil, dispersed oil, oil in water emulsion, dissolving oil, oil-solidss.Dissimilar oily(waste)water will adopt different treatment processs, can be divided into 4 kinds both at home and abroad at present: Physical, chemical method, physico-chemical processes and biochemical process containing the treatment technology of mineral oil sewage by handling principle.
(1) Physical:
The emphasis of physical treatment process removes containing the mineral substance in mineral oil sewage and most of suspended solid, wet goods.Comprise the methods such as gravity separation, centrifugation, coarse, filtration, membrane sepn.
(2) chemical method:
Method of chemical treatment is mainly for the treatment of containing can not a part of colloid of independent physical method or biological method removal and dissolved matter in mineral oil sewage, and conventional method has chemical demulsification method, chemical oxidization method etc.
(3) physico-chemical processes:
Physico-chemical processes mainly comprises By Bubble-floating Method, absorption method, electrochemical process, ultrasonic separation method etc., and these methods generally all have the advantage that adaptability is comparatively strong, selectivity is wide.
(4) biochemical process:
Biological chemistry (biochemistry) facture is the biochemical action utilizing microorganism, is simple material, thus toxic substance is converted into non-toxic substance by the organic substance decomposing of complexity, and oily(waste)water is purified.Microorganism can using organism as nutritive substance, and make a wherein part be absorbed into as the organic composition in microbe or be proliferated into new microorganism, rest part can be resolved into simple organic or inorganic material by microbiological oxidation.
Because above-mentioned traditional administering method all exists certain shortcoming, therefore, be necessary to break away from existing Treatment process route, hew out and be separated and process the new way of trade effluent mineral oil, and then develop a kind of trade effluent mineral oil further treatment technique of new type.
Summary of the invention
