Description

Technical Field

[0001] The utility model relates to the technical field of high-efficiency carbon source preparation, in particular to a system for preparing a high-efficiency carbon source based on waste beverages. Background Art

[0002] In all regions of my country, there is a common phenomenon of excessive nitrogenous substances in sewage and too low carbon-nitrogen ratio. The organic matter content in low carbon-nitrogen ratio sewage is low, and conventional denitrification processes cannot meet the demand for carbon sources in the denitrification stage. Therefore, most sewage treatment plants are facing the current situation of insufficient carbon sources. Insufficient carbon sources not only affect the removal effect of nitrogen and phosphorus in the biochemical pool and the water quality of the effluent, but also damage the environment of subsequent sewage discharge. Studies have shown that among the more than 3,000 urban sewage treatment plants in the country, more than 40% of the sewage treatment plants have an annual average BOD5 / TN value of less than 3, and less than 20% of the sewage treatment plants have an annual average BOD5 / TN value of more than 5. External carbon sources have become an important choice to solve this problem. Glucose, methanol, sodium acetate, etc. have also become the most widely used carbon sources in sewage treatment plants, but their prices are too high, resulting in a significant increase in the operation and maintenance costs of sewage treatment plants, and there is also a risk of deteriorating tail water. Therefore, we provide a system for preparing efficient carbon sources based on waste beverages, aiming to provide sewage treatment plants with an economical, stable and efficient external carbon source. Utility Model Content
