Currently, there is too much oil and grease in our catering wastewater, slaughtering wastewater and some food wastewater, which leads to the decrease of the efficiency of biochemical system and the high COD of the effluent. Microbial decomposition bacteria can quickly decompose the large amount of oil and grease contained in the wastewater to improve the efficiency of the sewage system, reduce the COD of the effluent, so that the effluent of the sewage system to meet the relevant national standards.

Oil and grease is a combination of glycerol and 3 fatty acids, this decomposition of oil and grease special bacteria can cut off the combination of 3 fatty acids and glycerol, and decomposition of oil and grease special bacteria can be secreted outward to decompose oil and grease lipase enzyme, and oil and grease decomposition of enzyme in the final stage can be absorbed by the bacteria as a nutrient into the metabolism, and degradation of oil and grease and the water of the BOD, COD and part of the ammonia and nitrogen.
