Description

Printing and dyeing wastewater treatment system
Invention field
The present invention relates to a kind of Waste Water Treatment of handling dyeing and printing sewage that is mainly used in, belong to the environmental protection field.
Background technology
Dyeing waste water contains COD, BOD and the colourity of higher concentration, and wherein colourity can reach 100-400 times, BOD 5Can reach 100-400mg/l, COD CrCan reach 600-800mg/l, and biodegradability of organic matter wherein is poor, the quantity discharged instability adopts common biological treatment mode difficulty bigger.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of printing and dyeing wastewater treatment system, the technical process collocation rationally, can eliminate the organic pollutant in the dyeing waste water effectively, and by electric biochemical processing device electrolysis treatment process and biological treatment process are integrated, not only bring into play electrolytic redoxomorphism, also improved the environment of biological treatment simultaneously, improve whole processing power and treatment effect, realized satisfied treatment effect.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of printing and dyeing wastewater treatment system, mainly by the preaeration equalizing tank, one heavy pond, hydrolysis acidification pool, aerobic biofilter, second pond and electric bio-oxidation treatment facility constitute, described preaeration equalizing tank, one heavy pond, hydrolysis acidification pool, aerobic biofilter, second pond and electric bio-oxidation treating pond interconnect successively, described electric bio-oxidation treatment facility comprises housing, be provided with the space that constitutes water stream channel in its housing, be provided with biologic packing material in the space of described formation water stream channel, also be provided with some counter electrode, the bearing of trend of described electrode is vertical mutually with the bearing of trend of described water stream channel.
Because the present invention has adopted rational processing step and processing unit, earlier unsettled draining is regulated, carrying out preaeration simultaneously in the process of regulating handles, improve its organic biodegradability by hydrolysis acidification pool, and carry out purifying treatment by aerobic biofilter efficiently, organic pollutant content in the sewage after the processing reduces significantly, handle for the efficient electric bio-oxidation that wherein partly is difficult to the electric bio-oxidation treatment facility of biodegradable process again, by in water, forming partial electrolysis, the Oxidizing and Reducing Agents that generates carries out oxidation or reduction reaction to the organism in the water, biology direct and on every side contacts, help to improve the speed of biological treatment, and reduce the density of electrolysis resultant at any time, make electrolytic equilibrium help direction object space exhibition to resultant, improve electrolytic effect, formed mutually promoting of biological treatment and electrolysis treatment thus, make whole structure be better than electrolysis and biological two independent treating processess, although at present because biological complicacy, also do not understand biological mechanism of answering under the electrolysis fully, but this structure of mutually promoting is sure.In addition, because electrode direction is vertical with water (flow) direction, the electric field change that helps the route of current process, making different water all pass through similar electric field alternately changes, avoid the treatment effect because of the uneven influence integral body that weighs of the treatment effect of each several part current, it is just accurate to make final outflow water meet country's discharging.
