Liquid lime fermentation strain composition and livestock wastewater purification treatment method using the same

摘要

The present invention is to purify livestock wastewater such as livestock manure discharged from large animals such as cattle and pigs using a lime fermentation strain composition, and treat livestock wastewater at the same time using a liquid lime fermentation strain composition. This is to simultaneously process the purification of the sludge generated later. The lime fermentation strain composition according to the present invention is prepared by mixing 50 to 150 parts by weight of the liquefied strain in 100 parts by weight of water containing lime in a concentration of 70 to 90%. The lime fermentation strain is fermented in a closed state, and the fermentation temperature is fermented at 30 to 37° C. for 20 to 40 days to prepare a liquid lime fermentation strain composition. The liquid lime fermentation strain composition is added to livestock wastewater to be treated, but the liquid lime fermentation strain composition is mixed in 1L of livestock wastewater at a ratio of 10 to 100g of the liquid lime fermentation strain composition to improve the water quality of contaminated livestock wastewater. Cleanse. The liquefied strain is a liquid strain cultured at 32 to 37°C for 24 to 48 hours by mixing 1 to 5 parts by weight of a Bacillus strain or 2 to 7 parts by weight of a strain of the genus Paenibacillus to 100 parts by weight of water Use The water purification method using the liquid lime fermentation strain composition of the present invention is to purify livestock wastewater including livestock manure such as pigs or cows using the liquid lime fermentation strain composition.
