Influence of the different filtrate thickness of table 3 to waste water indices removal rate
It can be seen that removal rate average value COD > TS > TP > TN, TS removal rate, TP removal rate, TN removal rate from table 2 and table
As the trend that is gradually increased, TS removal rate and TN removal rate is presented as filter cloth thickness is increased by 4mm in the increase of filter cloth thickness
It is slightly larger to 6mm increasing degree, increase tend towards stability later；As filter cloth thickness increases to 8mm by 4mm, TP removal rate increases
2.36%, subsequent amplification is smaller；Filter cloth thickness increases to 8mm by 4mm, and COD removal rate increases by 1.49%, 10mm to be reduced compared with 8mm
The reason of 2.54%, 12mm increase by 1.65% compared with 10mm, and COD removal rate is caused to fluctuate may be that waste water is gone out by gap between filtrate
Existing short circuit causes, and the overall increase that can be seen that filter cloth thickness, waste water and filter cloth time of contact extend, and contact area increases, and increases
Dissolve the effect of substance in strong filter cloth arrested particles and absorption waste water, there is increase in various degree in filtered wastewater pH,
And as the increase of filter cloth thickness, pH value are gradually increased, this and filter cloth itself are to H+、OH-Selective absorption is related.Conductivity has
Different degrees of decline, the biggest drop reaches 16.66% when filtrate thickness 8mm, and the reduction of conductivity of waste water reflects filter cloth after filtering
It is limited to water intermediate ion removal ability.Utilize SPSS statistics20.0 software analysis data, multivariate analysis of variance result
COD removal rate, TS removal rate, TP removal rate, TN removal rate correspond to P value be respectively 0.689 > 0.05,0.652 > 0.05,
0.337 > 0.05,0.307 > 0.05, under 0.05 level of signifiance, the variation of filtrate thickness to COD removal rate, TS removal rate,
