NOVELTY - Treating photovoltaic solar battery sheet production wastewater, comprises: separately collecting acid wastewater and alkaline wastewater; regulating pH value and forming treating solution; removing fluorine and/or removing carbon oxygen demand (COD) from treating solution; adding calcium salt into the treating solution to remove fluorine ion in wastewater; during removing COD, treating the treating solution by carrying out incomplete anaerobic reaction; then treating by aerobic organisms; and orderly finishing the above steps and discharging the wastewater which reaches the standard.    USE - The method is useful for treating photovoltaic solar battery sheet production wastewater.    DETAILED DESCRIPTION - Treating photovoltaic solar battery sheet production wastewater, comprises: separately collecting acid wastewater and alkaline wastewater; regulating pH value, adding strong acid or strong alkali into acid wastewater, alkaline wastewater or mixed wastewater of acid wastewater and alkaline wastewater for regulating pH value to 8-8.5 for forming treating solution; removing fluorine and/or removing carbon oxygen demand (COD) from treating solution; adding calcium salt into the treating solution to remove fluorine ion in wastewater; during removing COD, treating the treating solution by carrying out incomplete anaerobic reaction; then treating by aerobic organisms; and orderly finishing the above steps and discharging the wastewater which reaches the standard. An INDEPENDENT CLAIM is also included for a wastewater treating system to perform the above process, comprising: a wastewater collecting pool which is composed of an acid wastewater pool and an alkaline wastewater pool for collecting the acid wastewater and the alkaline wastewater; a pH value regulating pool connected with the acid wastewater pool and the alkaline wastewater pool, an acid and alkali feed port is arranged on the pH value regulating pool to add into strong acid or strong alkali for regulating the pH value of the wastewater; a unit for removing fluorine which is used for removing the fluorine ion, and comprises a reaction pool and a precipitating pool, pH value regulating pool, reaction pool and precipitating pool are orderly connected with each other, a feed port is arranged on the reaction pool, and a chemical sludge discharging port and a water outlet are arranged on the precipitating pool; an incomplete anaerobic reaction pool connected with the water outlet of the unit for removing fluorine and the pH value regulating pool for carrying out incomplete anaerobic reaction; and an aerobic organism reaction unit for carrying out aerobic organism treatment, which comprises an aerobic organism reaction pool and a biochemical precipitating pool, an incomplete anaerobic reaction pool, an aerobic organism reaction pool and a biochemical precipitating pool are orderly connected with each other, and the biochemical precipitating pool is provided with a wastewater discharging port and a biochemical sludge discharging port.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the process for carry out the photovoltaic solar battery sheet production wastewater treatment.
