The invention relates to a composite microbial viable bacteria preparation and an application thereof in high-concentration pig-raising wastewater. The composite microbial viable bacteria preparationis a bacterial suspension which comprises Bacillus cereus 2-2, Pseudomonas sp. C2-1, Pichia pastoris 2-6 and Lactobacillus zeae 2-20, wherein the viable count of Bacillus cereus 2-2 is greater than orequal to 1.48*1010 CFU/mL, the viable count of Pseudomonas sp. C2-1 is greater than or equal to 2.04*1010 CFU/mL, the viable count of Pichia pastoris 2-6 is greater than or equal to 0.98*1010 CFU/mL,and the viable count of Lactobacillus zeae 2-20 is greater than or equal to 1.78*1010 CFU/mL. The composite microbial viable bacteria preparation is used for treating wastewater containing high-concentration COD and NH3-N, thereby achieving high-efficiency removal of COD and nitrogen. 本发明涉及种复合微生物活菌制剂及其在高浓度养猪废水中的应用。本发明中的复合微生物活菌制剂，是由蜡样芽胞杆菌2-2、假单胞菌C2-1、曼氏毕赤酵母2-6和玉米乳杆菌2-20组成的菌悬液，其中，蜡样芽孢杆菌2-2活菌数大于等于1.48×10CFU/mL，假单胞菌C2-1活菌数大于等于
