￣deng inorganics. because organism mostly is aromatic compounds and poisonous organic solvent, also have the inorganic salt (Cu particularly of high density simultaneously
2+).It is a difficult problem that saccharin wastewater is processed always.
After utilizing the utility model to saccharin wastewater biochemical treatment, carry out advanced treatment.Through trimestral test, after biochemical treatment, effluent quality, generally in 300mg/L left and right, adopts the utility model, and gac dosage is about 0.6kg/t left and right, and the effluent COD concentration after processing is in 90mg/L left and right.If employing single stage adsorption, dosage is about 1.3kg/t.In process of the test, dosage can be saved 1/2 left and right, if according to 4000 yuan of meters of gac per ton, if every processing 1t saccharin wastewater cost calculates according to single stage adsorption, cost is 5.2 yuan, and according to this technique, cost is only 2.6 yuan.Visible cost for wastewater treatment reduces greatly.So just make adsorption technology can obtain practical engineering application.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
