Description

Four phase catalytic oxidizing equipments
Technical field
The utility model belongs to technical field of waste water processing, is related to a kind of four phases catalytic oxidizing equipment.The main pin of the device To the industrial enterprise such as COD high of the industry such as pharmacy, chemical industry, agricultural chemicals, coking, fuel discharge, it is highly-saline, with bio-toxicity or The waste water COD of person's biological inhibition effect is removed.
Background technology
High salt, COD high, there are bio-toxicity or the wastewater treatment always enterprise headache the most of biological inhibition effect to ask Topic, its content of organics is high, and biodegradability is poor, it is difficult to be degraded by microorganisms.For such waste water, more typical handling process bag Include:(1), absorption method;(2), air/ozone oxidation technology;(3), Feton oxidation technologies;(4), electro-catalytic oxidation technology;(5)、 Incineration technology.But the characteristics of these methods have oneself and limitation.
(1), adsorption treatment process, when high-concentration waste water is processed, is adsorbed mainly for the advanced treating of low concentration wastewater Agent is very easy to reach adsorption saturation state, and frequent replacement cost is expensive, it is necessary to regenerate in vitro when using regeneration treatment, It is cumbersome, and loss is big;
(2), air/ozone oxidation technology, air aeration oxidation technology is mainly used in biological treatment aerobic section, for can The preferable waste water of biochemical, is a kind of most currently used technique according to the advantage for having low energy consumption, but for high concentration COD, tool There is the waste water of bio-toxicity or inhibitory action, its oxidability is too weak, and treatment effect is excessively poor.Ozone oxidation has oxidability By force, reaction speed block, science and engineering at the advantages of sludge and secondary pollution, its successive depths generally as wastewater treatment is not produced Section, when high concentration wastewater treatment is directly applied to, the huge but utilization rate of dosage is low, and ozone oxidation has certain selection Property, might not well aoxidize many organic pollution materials;
(3), Feton oxidation technologies are produced greatly by a certain proportion of FeSO4 and H2O2 is added in waste water, making in waste water The OH groups of amount, using poisonous and harmful substance and the organic matter of difficult degradation in the strong oxidation performance and waste water of OH groups React and generate harmless carbon dioxide and water and reach the purpose of pollutant removal, with quick, efficient, pollution-free etc. Advantage, but technology PH accommodations are narrow, it is necessary to adjust PH for 3-5, while Fe2+ consumptions are big, can produce after the reaction substantial amounts of Iron containing sludge is precipitated, and H2O2 consumptions are big, and processing cost is high;
(4), widely, advantage is a lot, mainly there is treatment for electro-catalytic oxidation technology application study in the treatment of waste water Efficiency high, easy to operate, applied widely, controllability easily realizes by force automation, the advantages of environment compatibility is good, but due to pole plate The reasons such as material, processing solution electric conductivity, filler composition material limit, its often oxygen evolution potential it is low, in catalytic degradation water Organic matter when, can cause that current efficiency reduction, electrode life are short, substantial amounts of energy consumption is used for the shortcomings of produce hydrogen, oxygen. Such as:Two-dimentional electrocatalytic oxidation, its mainly produce hydroxyl radical free radical position be battery lead plate plan-position;Conventional three-dimensional electrocatalytic oxidation Change, although produce hydroxyl radical free radical to occur in whole container space, but its filling system cost when using noble metal catalyst Higher, the easy dissolution of noble metal, carbon distribution lose catalysis activity.Equally when using dissolution formula irony battery lead plate, can produce a large amount of Molysite sludge settling, and use the pole plate of non-dissolution and during relatively low water quality treatment salinity, its needs takes operation electricity higher (voltage is raised pressure, and the speed of electrolysis water accelerates, and substantial amounts of energy consumption is used for electrolysis water rather than hydroxyl radical free radical is produced, while producing The substantial amounts of hydrogen of life and oxygen), or add electrolyte in addition (such as NaCl increases extra processing cost);
(5), the incineration treatment technology of waste water is mainly for COD>100000ml/L, calorific value>4.1868*2500kJ/kg's High-concentration waste water, the waste water burning method treatment relatively low for COD concentration is more consumed energy than other method, does not possess actual behaviour The property made.When higher containing chlorine ion concentration in solution, incinerator corrosion is very serious.
