Abstract

The invention belongs to the field of waste water biological strengthening treatment, and concretely relates to an activation promoter capable of increasing microbiological treatment effect of daily chemical waste water. The daily chemical waste water has the characteristics of high organic matter, high salt and biological toxicity, and treatment by using a conventional biology method is difficultto reach the standard. The activation promoter comprises chitosan, glycine betaine, ferrous sulphate, trehalose, citric acid, proline, and composite vitamin, can effectively improve the survival breeding capability and metabolic activity of microbe under conditions of high organic matter and high salt, and can effectively increase the sewage processing effect. The activation promoter has the advantages of low cost and convenient making, and can be used for biological treatment of daily chemical waste water and other high-salt surfactant waste water.

Description

technical field [0001] The invention belongs to the field of wastewater biointensified treatment, and in particular relates to an activation accelerator for improving the microbial treatment effect of wastewater in the daily chemical industry. Background technique [0002] Daily chemical wastewater refers to the wastewater generated during the production of daily chemical products (such as shampoo, hand sanitizer, laundry detergent, and washing powder, etc.). The main characteristics of this type of wastewater are large discharge, high concentration of organic matter (mainly containing surfactants, including anionic surfactant sodium dodecyl sulfate SDS and nonionic surfactant Pingpingjia), and high salt content. If not effectively controlled and treated, surfactants in wastewater will slowly accumulate in the environment and cause harm to the ecosystem. [0003] At present, there are few reports on the treatment of high-salt daily chemical wastewater. The reported treatmen...
