Description
Technical field
The invention belongs to the field of purification of waste water, particularly relate to a kind of advanced waste treatment system.
Background technology
To economize on resources and protection of the environment is the fundamental state policy of China." 12 " period, National urban sewage treatment and recovery utilization ratio will reach the target of 10%, can save fresh water resource more than 70 hundred million m every year
3, this can alleviate China effectively, and the problem of especially Water Resources In Arid Regions shortage, therefore waste water recycling has important practical significance.
The total quantity of wastewater effluent in the current whole nation is more than 700 hundred million tons, and the consumption of national reuse water only has 16.6 hundred million m
3, only account for 2% of national wastewater/sewage quantity discharged, the target of distance 10% falls far short.Therefore to complete this target and not only depend on the macro adjustments and controls factor such as the guiding of national policy, the adjustment of market water price, more need the reliable Sewage advanced treatment efficient, clean, reduced investment, running cost are low and the practical application of reuse technology, therefore reuse water future investments space is very wide.
Reuse water refers to that city domestic sewage and factory effluent etc. reach the discharge water of emission standard after pre-treatment and biochemical process process, again after further processing, reach the water quality standard of a certain purposes, be back to the Ecology of this production process as industrial cooling water, garden landscape irrigation etc.But in wastewater to reach standard treating processes, the parent compound in former sewage/wastewater there occurs significant change, is not only embodied in the composition of compound, changes in nature, and its molecular conformation has different significantly from size.Therefore, continuing with biochemical process in advanced treatment is main purification process, then often to COD(chemical oxygen demand) etc. to close the removal efficiency of key control water-quality guideline very low.The treatment technology of current reuse water common are membrane technique, MBR method, Fenton reagent oxidation style, photocatalytic oxidation etc., or with other physical chemistry methods, as the combination process of flocculation, filtration etc.But not only there is the particular problems such as treatment scheme is long, floor space is large, running cost is high in these combination procesies; A large amount of mud can be produced in treating processes simultaneously.These moisture percentage in sewage sludge are high, and processing cost is high, and the mud especially containing I pollutant is all the more so.The environomental pollution source that the direct discharge of mud or mud miscarriage become new with regard to making the sewage work disposed of sewage, has now caused showing great attention to of various circles of society, has also become new problem urgently to be resolved hurrily in current wastewater treatment process.
Great many of experiments finds, the catalytic electrolysis efficiency of catalyzer is not only relevant to the current density value of working electrode, strength of electric field, and in close relations with its potential difference size in resuspension procedure on instantaneous displacement.The precondition that experiment proof catalyzer effective activation dissolved oxygen becomes active oxygen needs to exist the voltage difference being greater than more than 0.66V on a suspension path.Therefore, in existing Waste Water Treatment, be provided with tens of to working electrode at the two ends of reaction tank, adopt this mode of production, when when full production, the electrolyzer power supply required for certain current density be applied on often pair of working electrode must have high total supply current and export and relatively low operating voltage; Also need the supply main (wire cross-section area is very large) can bearing very high currents intensity matched with this power supply simultaneously, and then be assigned on often pair of working electrode.This adds processing request and the manufacturing cost thereof of power supply and supply main undoubtedly.
Especially for the double-electrolyzer Waste Water Treatment after improving, in this double-electrolyzer Waste Water Treatment, adopt insulating material that single electrolyzer is therefrom separated into two homalographics or isometric(al), double-electrolyzer that structure is consistent.Therefore, when double-electrolyzer tandem working, need to provide two to overlap the working electrode of independently transmitting line and twice quantity to (its working area reduces 1 times) outward, time under optimum oxidation state with full production, also need the working current often pair of working electrode in two electrolyzers applying same current density.Therefore, this total current value just causing the working electrode that is installed in parallel right is high, now just need to bear the supply main (wire cross-section area is very large) of very high currents and coupling thereof power supply (its have high electric current export with 10V within relatively low operating voltage).
