| Abstract: | 98% of the wastewater in the dairy industry belongs to the whey washing wastewater, the main components of the wastewater are protein, fat, dry matter, etc., and the biochemical performance is particularly good. The wastewater treatment process of dairy products is hydrolytic acidification + anaerobic + good nutrition process. In general dairy production enterprises, the average COD of wastewater inlet is 2000-2500mg/l, and the anaerobic part of the wastewater treatment process can produce a large amount of biogas. In the early design of wastewater treatment of dairy products, most of them were discharged by direct combustion of the torch, which not only wastes resources, but also has ecological environment and safety production risks. This paper considers that a set of biogas recovery and treatment system and biogas boiler system can be designed to realize resource recovery and utilization, which can not only save energy, but also reduce the total carbon emission of enterprises. After analyzing the sewage index of Mengniu Dairy (Maanshan) Co., LTD., this paper decided to first collect the gas generated in the anaerobic stage by using biogas recovery system, then use biogas desulfurization device to remove the sulfur in the gas, and finally enter the biogas boiler for combustion and output steam for utilization. The above treatment process can effectively utilize biogas and achieve energy saving and consumption reduction. |
