The a small amount of pernicious gas and waste liquid evaporated when two hybrid reaction tanks heat in waste liquid generated during degradation reaction
Pernicious gas.
The concrete application embodiment of high COD waste liquids is handled using above-mentioned compound advanced oxidation technology：
(1) the high COD cutting fluids waste liquid of certain factory is handled, treatment effect is shown in Fig. 2.As can be seen that in initial treatment 4h,
As processing time extends, total organic carbon (TOC) concentration in waste liquid is of a straight line type rapid decrease, and the TOC concentration of waste liquid is from first
Beginning, 19000mg/L was reduced to 2000mg/L or so；As processing time extends after 4h, TOC concentration slowly reduces, until processing
16h, TOC concentration are close to zero.Thus illustrating, the Best Times of the degradation treatment cutting fluid waste liquid are initial 4h, after 4h, place
Reason efficiency slows down.
(2) high COD degreasings waste water is handled, treatment effect is shown in Fig. 3.As can be seen that in initial 2h, with processing time
Extend, COD concentration is of a straight line type rapid decrease in waste liquid, and the COD concentration of waste liquid is reduced to from initial 26000mg/L or so
2000mg/L or so；As processing time extends after 2h, COD concentration slowly reduces.Thus illustrate, the degradation treatment degreasing is given up
The Best Times of water are initial 2h, after 2h, without apparent treatment effect.
(3) printing house's board-washing high-COD waste water is handled, the result is shown in Fig. 4.As can be seen that in initial 2h, during with processing
Between extend, COD concentration is of a straight line type rapid decrease in waste liquid, and the COD concentration of waste liquid is reduced to from initial 8000mg/L or so
500mg/L or so；As processing time extends after 2h, COD concentration slowly reduces.Thus illustrate, the degradation treatment printing house
The Best Times of waste water are initial 2h, after 2h, treatment effect unobvious.
