Abstract: PURPOSE: To stably, economically and efficiently treat acidic org. waste gas, by using alkaline washing water containing a basophilic bacterial group capable of decomposing an acidic org. component.
CONSTITUTION: Alkaline washing water, which contains a basophilic bacterial group being bacteria having high activity in a high alkali region of a basophilic bacillus genus and has capacity for decomposing an acedic org. component such as phenol, is sprinkled from a washing water sprinkling port 3 to be subjected to the countercurrent gas-liquid contact with waste gas containing a acidic org. component such as phenol on leak shelves 4. The washing water is kept alkaline by the supply of an alkali agent and the basophilic bacterial group in a washing water tank 8 is aerobically cultured by oxygen in waste gas or oxygen sent from a blower 9 according to necessity to keep biological activity and the acidic org. component transferred to the alkaline washing water is rapidly separated and removed.

Abstract: PURPOSE: To economically treat exhaust gas while enabling the recovery of a hydrophobic org. substance, by washing exhaust gas with washing water containing bacteria to decompose a hydrophobic org. substance and subsequently containing the treated gas with an adsorbable solid to remove the remaining hydrophobic org. substance by adsorption.
CONSTITUTION: Exhaust gas 1 containing a hydrophobic org. substance and a hydrophobic org. substance is sent to a gas-liquid contact part 2 to be brought into contact with washing water 4 containing bacteria from a recirculation washing water tank 13 to perform the absorptive removal of the hydrophobic org. substance. Washing water 5 after absorption is flowed into the recirculation washing water tank 3 and all of or a part of the hydrophobic org. substance is decomposed by bacteria. The exhaust gas 6 passed through the gas-liquid contact part 2 is guided to and adsorbing part 7 packed with activated carbon to perfomm the adsorptive removal of the hydrophobic org. substance. In this case, because the hydrophobic org. substance such as phenol is already removed, the lowering in adsorptive capacity can be prevented by the covering of the surface of activated carbon with a phenol polymer. The adsorbent is desorbed by steam 9 and desorbing gas is condensed under cooling and the hydrophobic org. solvent is separated and recovered by the difference of specific gravity.

Abstract: PURPOSE: To efficiently remove the copper ion and org. substance in waste water, by a method wherein a neutralizing agent is added to treated water after electrolysis to remove the precipitate therein and, thereafter, microorganism treatment is applied to the treated water while a part of the flowed out water is combined with the stream of neutralization and flocculative precipitation treated water.
CONSTITUTION: Treated water 3 receiving electrolytic treatment in an electrolytic treatment tank 2 is sent to a pH control tank 4 and the pH thereof is pref. adjusted to about 10 by a neutralizing agent. Subsequently, the pH controlled water is sent to a precipitation tank 7 to be separated into a precipitate 8 and a supernatant liquid 9 while the supernatant liquid 9 is sent to a microorganism treatment and conditioning tank 10 and, if necessary, diluted and conditioned by return discharge water 18 to obtain microorganism treated inflow water 11. This microorganism treated inflow water 11 is sent to a microorganism treatment tank 12 to receive the decomposition of the residual org. substance by a microorganism and sent to a precipitation tank 16 as microorganism treated outflow water 15. Excessive sludge is withdrawn from the precipitation tank 16 and supernatant water 17 is discharged.
