The invention discloses a method for lowering para-toluenesulfonic acid waste water COD through an A2/O2 biological method. Waste water sequentially flows through a water inlet adjusting tank, a first-level anaerobic mixing tank, a first-level anaerobic mud lifting tank, a first-level aerobic aeration tank, a first-level aerobic mud lifting tank, a second-level anaerobic mixing tank, a second-level anaerobic mud lifting tank, a second-level aerobic aeration tank, a second-level aerobic mud lifting tank and a final sedimentation tank; water soluble alcohols and micromolecule organic acid are added to anaerobic activated sludge of the mixing tank at the anaerobic stage; water soluble alcohols, organic acid and monosaccharide are added to aerobic activated sludge of the aeration tank at the aerobic stage. By means of the method, biodegradability of para-toluenesulfonic acid can be improved, and para-toluenesulfonic acid pretreatment time and cost are reduced. Added agentia is safe, free of toxicity, sufficient in agentia source, easy and convenient to make, low in production cost, long in shelf life and can obviously lower the value of COD in waste water, so that safe emission is reached.
Description
Technical field
The present invention relates to a kind of method of wastewater treatment, waste water especially contains the method for wastewater treatment of p-methyl benzenesulfonic acid.
Background technology
P-methyl benzenesulfonic acid is a kind of important industrial chemicals, has stronger bio-toxicity and inhibitory action.Traditional biological A/O method is difficult to its waste water is processed.Owing to the biodegradability of p-methyl benzenesulfonic acid is poor.Current p-methyl benzenesulfonic acid wastewater biological A/O processes needs multiple method to carry out pretreatment, such as By Ozone, photocatalytic oxidation etc., these methods can improve wastewater biodegradability to a certain extent, but there is number of drawbacks, as: operating cost is higher, and materialization reagent consumption amount is big, and solid waste yield is big.
Summary of the invention
It is an object of the invention to provide a kind of method that can effectively reduce p-methyl benzenesulfonic acid waste water COD.
The technical solution adopted for the present invention to solve the technical problems is:
To sequentially pass through into water regulating reservoir, one-level anaerobism mixing pit containing p-methyl benzenesulfonic acid waste water, one-level anaerobism carries mud sump, one-level aerobic aeration pond, one-level is aerobic carries mud sump, secondary anaerobic mixing pit, secondary anaerobic carries mud sump, two grades of aerobic aeration ponds, and two grades aerobic carries mud sump and final deposition pool；Mixing pit and interpolation water soluble alcohols and small molecular organic acid in the anaerobic activated sludge carried in mud sump at anaerobic stages；Aeration tank and interpolation water soluble alcohols, organic acid and monosaccharide in the aerobic activated sludge carried in mud sump at aerobic stage；Interpolation water soluble alcohols is methanol, ethanol, ethylene glycol, propanol, propylene glycol, the one of butanol or two kinds or three kinds.
Small molecular organic acid is formic acid, acetic acid, propanoic acid, butanoic acid, lactic acid and the one in sodium salt thereof or two kinds or three kinds.
Anaerobic stages anaerobic activated sludge adds the volume that volume is water soluble alcohols 5 to 25 times of small molecular organic acid, according to wastewater volume 100,000/prepare to one of percentage.
Organic acid is malic acid, citric acid and the one in sodium salt two kinds or three kinds thereof.
Monosaccharide is xylose, glucose, fructose, the one in galactose two kinds or three kinds.
Aerobic stage, organic acid is water soluble alcohols 3 to 10 times added in aerobic activated sludge, monosaccharide is water soluble alcohols 2 to 5 times of interpolation, prepare according to million/mono-to one thousandth of wastewater volume.
The present invention can be directly used for biological A2/O2The anaerobic activated sludge of method and aerobic activated sludge, it is possible to improve the biodegradability of p-methyl benzenesulfonic acid, reduce time and the cost of its pretreatment.The own safety non-toxic of medicament added, medicine source is abundant, and simple for production, production cost is relatively low, and the shelf-life is longer, aerobic through secondary anaerobic and two grades, can substantially reduce the COD value in waste water, reach safety dumping.
