STUDY ON SOME POLLUTANT SUBSTANCES TREATMENT IN SMALL AND MEDIUM SIZE OF BREEDING WASTE WATER BY ZEOLIT SUBTITLES X.P1 COMBINED WITH ALUMINUM OXIDE
Abstract
The research results are performed by authors on wastewater samples of pig farms, located in Ngoc Van - Tan Yen - Bac Giang with a scale of less than 200 pigs. During the farming process, the farm has discharged a large amount of livestock wastewater containing many components polluting the environment, especially organic compounds. Although the farm has invested in biogas systems for treatment, the quality of wastewater after the biogas has not met the standards. Adsorption materials for the treatment include Zeolite X.P1, Al2O3. The study results showed that the optimal value of Zeolite X.P1 is 5g and 0.3g Al2O3 for 200mL of wastewater. The processing efficiency of the numbers is TSS reaching 59.69 - 84.31%, COD reaches 84.9 - 87.47%, BOD reaches 88.65 - 91.58%, Nitrogen reaches total 89.98 - 91% and total phosphorus reached 41.74 - 48%.
