Property sludge reflux is to biological membrane separation zone pond body top.Flow of inlet water is gradually increased to design discharge by low, and continuous operation 7 days, when
65% is reached to the removal rate of COD, to the removal rate average out to 65% of ammonia nitrogen, 20% or so has been reached to the removal rate of TN and TP,
It is believed that biofilm success.
The water outlet status of reaction unit after measuring biofilm success, obtains device to the removal effect of COD, such as 2 institute of attached drawing
Show.Figure it is seen that effluent COD concentration is relatively stable, and 56.6 mg/L of average out to, average removal rate 63.1%.It uses
Spectrophotometry measures biological membrane separation zone pond body along the nitrogen concentration of journey, obtains nitrogen concentration with the situation of change along journey, obtain as
Attached drawing 3.From figure 3, it can be seen that nitration reaction occurs mainly in ceramic packing area, it is segmented along ceramic packing layer height and carries out carbon oxygen
Change and nitration reaction.
From fig. 4, it can be seen that the removal rate to TN is 66% when reflux ratio is 3, although when reflux ratio is 4, to TN
Removal rate rise to 68%, but higher reflux ratio means to consume more energy, therefore economically, in TN
In the case that removal rate is not much different, preferably select reflux ratio for 3.
Handle sewage example:
Reaction unit structure as shown in Figure 1, above-mentioned inoculation tame process after, the water-in and water-out flow of stable operation stage
Using design discharge, reflux ratio 3.Average removal rate to COD is 63.1%, reaches " urban wastewater treatment firm pollutant emission
Standard " (GB18918-2002) level-one B standard.NH4+-N is averagely only 1.91mg/L, TN average out to 9.60mg/L, removal
Rate is 68.6%, has reached the level-one A standard of 2002 standard of GB18918-.
