Description
Technical field
The present invention relates to a kind of leaf mustard pickling waste water processing equipment, belong to technical field of sewage.
Background technology
Vegetable-pickling is a kind of common preservation edible way, such as southern hot pickled mustard tube, the leaf mustard in the north in China.Vegetables
Curing process produces a large amount of high organic wastewaters of high salt, because high salinity is inhibited to microbial activity, therefore such
Pickling waste water is treated as a great problem.
The conventional processing method of high-salt wastewater is the physical treatment sides such as electrolysis, membrane separation process, burning method or deep well injection
Method.Electrolysis and the high operating cost problem of burning method, the film blockage problem of membrane separation process and the secondary pollution of deep well injection
Problem all limits practical application, and because substantial amounts of vegetable-pickling scope of the enterprise is smaller and distribution scattered, therefore, cost compared with
The complicated sewage disposal technology of high, operational management is not particularly suited for the processing of such waste water.Activated sludge process has economical, high
Effect, operational management it is simple, it is applied widely the features such as, be widely used in all kinds of wastewater treatments.But the height of pickling waste water
Salt environment has inhibitory action to biochemical treatment, under high salinity environment, microbial metabolism enzymatic activity is obstructed, biology increasess slowly,
Yield coefficient is low, strongly limit application of the activated sludge process in high-salt wastewater process field.
Iron-carbon micro-electrolysis technology is a kind of ideal technology of current processing high concentrated organic wastewater, the technique be used for high salt,
COD and colourity can be not only greatly reduced in difficult degradation, the processing of high-colour intensity wastewater, be also greatly improved the biochemical of waste water
Property.The technology is that in the case of cold, " galvanic cell " effect is produced using the micro-electrolysis stuffing filled in light electrolysis equipment
Waste water is handled.After water flowing, it can be formed in equipment " galvanic cell " that countless potential differences reach 1.2V." galvanic cell " with
Waste water does electrolyte, and form electric current by electric discharge carries out electrolytic oxidation and reduction treatment to waste water, to reach degraded organic contamination
The purpose of thing.The main electrodes occurred in iron-carbon micro-electrolysis filler react：
Anode reaction (Fe):
Fe-2e-→Fe2+ Eθ(Fe2+/ Fe)=- 0.44 (V)
Fe2+-e-→Fe3+ Eθ(Fe3+/Fe2+)=0.77 (V)
Cathode reaction (C)：
2H++2e-→2[H]→H2↑ Eθ(H+/H2)=0.80 (V) (acid condition)
O2+2H2O+4e-→4OH-, Eθ=0.40 (V) (neutral alkalescence condition)
4H++O2+4e-→H2O2, Eθ=1.23 (V) (acid excess oxygen)
The H of generation2O2Can be with the Fe in water2+The extremely strong hydroxyl radical free radical (OH) of reaction generation oxidability:
Fe2++H2O2→Fe3++·OH+OH-
Nascent state OH, [H], the Fe produced in said process2+、Fe3+Etc. can be aoxidized with many components in waste water
Reduction reaction, than if the chromophoric group or auxochrome group of the coloring matter in damaged colored waste water, or even chain rupture, reach degraded
The effect of decolouring；The Fe of generation2+It is further oxidized to Fe3+, their hydrate have stronger absorption-flocculation activity, especially
It is that ferrous hydroxide and ferric hydroxide colloid flocculant are generated after adjusting PH with base value is added, their flocculation ability is significantly larger than typically
The molecule that disperses in the obtained ferric hydroxide colloid of medicament hydrolysis, the water body that can largely flocculate, metallic and organic big point
Son, collective effect of its operation principle based on electrochemistry, oxidationreduction, physics and flocculation sediment.The technique, which has, is applicable model
Wide, high treating effect, short with low cost, processing time, convenient operating maintenance, the low advantage of power consumption are enclosed, can extensive use
In the pretreatment and advanced treatment of industrial wastewater.
