Description
Technical field
The present invention relates to a kind of high conductivity method of wastewater treatment based on two-stage AO device, belong to refractory wastewater
Field.
Background technology
Heavy metal leading indicator refers to hydrargyrum (Hg), cadmium (Cd), lead (Pb), chromium (Cr), arsenic (As), copper (Cu), zinc (Zn), cobalt
(Co), nickel (Ni) etc., they are present among environment with different forms, and migration, accumulation in the environment.With China's industry
Fast development, heavy metal wastewater thereby pollution problem is outstanding day by day, and the pollution rate of river,lake and reservior substrate is up to 80.1%.Its source
Extensively, mining, the industry such as metallurgy, chemical industry are main man-made pollution sources in water body.The approach of solution electroplating wastewater pollution is at all
Electroplating wastewater is carried out with advanced treating, and strengthens the recycling of resource.One side formation has up to standard with environment on a fairly large scale
Plating garden；On the other hand, it is easy to implement the effective treating method making electroplating wastewater qualified discharge.An electroplating industry huge sum of money at present
Belong to ion processing and recovery aspect achieved with breakthrough, but in electroplating wastewater after treatment, the content of Organic substance and nitrogen is past
Toward being unable to qualified discharge.The method solving is the electroplating wastewater after factory processes to be collected unified place carry out depth
Process.
Currently for the advanced treating of heavy metal wastewater thereby, mainly there are chemical precipitation method, oxidation-reduction method, absorption method, ion
Exchange process, membrane separation technique, electrochemistry and biological treatment etc..Wherein Biochemical method has low cost, high efficiency, Yi Guan
Reason, the feature of non-secondary pollution, are conducive to the improvement of ecological environment.Additionally, by being answered based on technology such as engineering, molecular biology
With.Biology can be made to have higher absorption, flocculation, regulation repair ability.Single method is often difficult to obtain preferable effect
Really, simultaneously using two kinds or more of methods, play the length of each technology, faster and better realize reaching and administer heavy metal wastewater thereby
Purpose.
Handling process for process commonly used pretreatment --- biochemical treatment --- advanced treating of electroplating wastewater.Its
In, pretreatment is mainly heavy metal ion and the cyanides such as the nickel removing in waste water, copper, cadmium.Biochemical treatment is mainly in waste water
COD, ammonia nitrogen and total nitrogen.Advanced treating is mainly the Organic substance removing bio-refractory in waste water, so that water outlet COD is met up to standard
Emission request.Traditional A/O technique i.e. interior circulation front establishment method, the ammonia nitrogen in waste water is in O pond through nitrosation
Effect is become nitrate nitrogen with Nitrification by oxidation by nitrobacteria, contains substantial amounts of nitrate nitrogen, enter A pond by internal reflux in the water outlet of O pond, is lacking
Under the conditions of oxygen, using the Organic substance in waste water as electron donor, nitrate nitrogen, as electron acceptor, nitrate nitrogen is reduced to nitrogen to denitrifying bacterium
Gas enters air, completes biological denitrification process, simultaneously the Organic substance in degrading waste water.But the total nitrogen concentration of electroplating wastewater exists
50-60mg/L, COD in 300-500mg/L, if adopt one-level A/O, water outlet total nitrogen in 20-30, COD in 80-90mg/L, and

4000mg/L.Common one-level AO or A2Activated sludge in O technique is affected larger, activity in Aerobic Pond by high conductivity
Mud is difficult to be formed floccule body, easily runs off.Chloride ion can play promotion enzyme anti-as the nutrient of microorganism in low concentration
The effect that, cell membrane equilibrium should be maintained and adjust Premeabilisation of cells pressure；If excessive concentration, also microorganism can be produced with suppression and poison
Evil effect, and these toxic actions show that microbial cell is dehydrated, and cause cellular plasm to separate；Salting out makes dehydrogenase
Activity reduces；High-salt wastewater salinity is high, leads to waste water density to increase, and activated sludge easily floats loss, thus affecting biology
The clean-up effect of processing system.
