The invention belongs to the technical field of low-carbon source sewage treatment, and relates to a pericarp coagulant and carbon source application technology for low-carbon source sewage. The technical points include the following steps. According to the amount of incoming raw water and the quality of raw water, as well as the specific reduction target of sewage treatment and the main process of biological treatment, the peel coagulant at 15 ° C ~ 25 ° C is added to the exposure in a certain way using the dosing equipment. In the gas pool, the dosage of the peel coagulant is 5g/m 3 to 100g/m 3 , and the aeration time is controlled from 0.5 hours to 24 hours. The peel coagulant in the present invention has dual functions, one is to have the effect of coagulation and removal of pollutants, and the other is to release carbon that is easily utilized by microorganisms. The peel coagulant as an external carbon source is the recycling process of the carbon source. The invention can be applied to the fields of low-carbon source urban sewage and industrial wastewater, and can also be applied to the fields of seasonal emergency algae removal of rivers and lakes, denitrification of phosphorus, organic matter removal and the like. |
